BRING THE BENEFITSOF NATURAL GAS TO
YOUR HOME
Determine availability at your home
To confirm that natural gas service is available at your home
go to WashingtonGas com. Depending on your location, more
research may be needed. If further research is required, an
email regarding availability will be sent in about three days
Have your contractor provide us with information
Your contractor will send along the number/type/BTU rating of
the gas appliances you are installing, distance from street to
desired meter location and gas pressure requirements. Along
with the appliance and pressure information, we will need a
scalable copy of your site plan or property plat with the meter
location clearly marked. To find a participating conversion
contractor or to download the required forms,
visit WashingtonGas com
Determine the total cost
Once the forms are submitted, Washington Gas will send you a
commitment letter outlining your cost, if any. (Please allow three
weeks or more for processing.) This cost, if required, would be
in addition to whatever your conversion contractor has quoted
for the natural gas equipment and installation, and contributes
to installing the gas service line, meter and regulator. If you are
using a Washington Gas Participating Conversion Contractor, all
costs for the natural gas appliances and appliance installation
can be financed (with approved credit) through financing options
provided by the contractor.

Steps to Convert Your Home to Natural Gas
76
Return the commitment letter
Washington Gas will not take any further action until you sign
and return the commitment letter and pay any installation
contribution (if required). If you do not return the commitment
letter, the price estimate is valid for six months from the date on
the commitment letter
Schedule all installations You will need to contact the underground contractor to schedule an installation date. As required by law, Washington Gas will have the utility locating service mark any public underground utilities. All private underground utilities—such as sprinkler systems, buried oil tanks, landscape lighting systems—must be located and marked by you. Once the underground line is installed, your gas meter will be installed (no scheduling is required). Then, contact your conversion contractor to install and arrange for inspection of all the interior gas piping and equipment.
Seven steps to add or replace natural gas appliances if you are already a Washington Gas customer
Newer natural gas appliances may have higher gas volume demands
and pressure requirements. To ensure proper installation:
1. Contractor verifies the total BTU input rating for existing appliance(s)
as well as the appliances being added and/or replaced.
2. Contractor verifies the gas pressure requirements that the
manufacturer suggests for the appliance(s) being added.
3. Contractor submits the Added Load/Split Meter Request Form to
Washington Gas
4. Washington Gas will determine if both the existing service line and
gas pressure to the home are adequate.
5. If it is determined that your existing service does not have the capacity
to handle the additional load, a service replacement will be required.
6. If a service replacement is not needed, the meter company will contact
the customer and/or contractor to schedule the installation and confirm
whether a contribution for the upgraded meter/split is required.
7. If a service replacement is required, the job will be designed as
a new service and you will receive a commitment letter with a
contribution quote, if any.

Split Meter
When adding a gas appliance, contractors may request
Washington Gas to install a split meter. In this application,
Washington Gas would install a new meter (or reinstall the
old meter) and two regulators to provide 2PSIG pressure to
the new appliances and 7.0 inches water column pressure to
the existing appliances where higher pressure is available.
When & Why Contractors Would Use a Split Meter
1. It can be less expensive and easier to run new gas piping
from the meter than tapping into the existing house piping
system
2. The existing low pressure house piping system is
inadequately sized for handling the additional load of a
new gas appliance.
3. The new gas appliance may require a higher gas pressure
that can be delivered by the existing system, thus making
the split meter the only feasible system to install.

NATURAL GAS HEAT IS CLEAN, COMFORTABLE AND EFFICIENT
HEAT YOUR HOME WITH NATURAL GAS
PROPANE FURNACE

Types of natural gas heating systems:
Forced-Air: This most common system uses
natural gas burners to heat air that is “forced”
through ductwork by a blower or fan
Hydronic: Steam or hot water, created by a
gas boiler, circulates through radiators, radiant
tubing built into the floor or baseboard units
Ductless: Whether it’s supplemental heat for
one room or even heating the whole house,
direct-vent furnaces require no chimneys or
ductwork
Combo: Combine heating, water heating and
sometimes even cooling in a single system
Today’s high-efficiency natural gas heating
systems—now up to 96% efficient—keep you
warm and comfortable on the chilliest days Since
space heating accounts for nearly half of your
annual gas usage and heating systems often
operate 15 hours a day during winter months,
increasing efficiency is the single most effective
way to reduce your gas bill
How much can you save? Compared to older
models with efficiency ratings of 60 to 65%, new
systems can save up to 40% on utility bills.
You’ll feel more comfortable than ever, too. A heat
pump just can’t match the warmth and comfort of
a natural gas heating system. Nor the reliability—
gas furnaces, on average, last twice as long as
heat pumps.

Making the right choiceFurnace size: To find the right furnace capacity for your home, have
your licensed HVAC contractor perform a load calculation.
Efficiency: High-efficiency furnaces may cost more to buy, but they
should cost less to operate monthly. Ask your contractor to provide
a pay-off period for the model you’re thinking of buying—that is, the
time it will take your energy cost savings to surpass the higher price.
Compare products and contractors: Prices may vary considerably.
Get written installation estimates and references from licensed
HVAC contractors
Installation: Make sure it’s been properly installed—ask your
contractor for all the test results specified in the manufacturer’s
installation instructions
Natural Gas Forced-Air Heating SystemsIn a forced-air system, the furnace draws cool air into a
metal box called a heat exchanger. There, it’s warmed by a
gas burner and forced through a filter and into ducts by an
electric fan or blower The air vented into rooms is about
120° Fahrenheit, as much as 30° warmer than air circulated
by an electric heat pump.1 Systems can feature electronic
air filters, electric cooling equipment, a humidifier, pilot-
less ignition, zone heating and venting directly through
basement walls
With forced-air systems, you not only enjoy a steady flow
of warm air, you heat your home faster while using less
energy And a gas furnace lasts two times longer than an
electric heat pump.

Making the right choice Boiler size: To find the right boiler capacity for your home, have
your licensed HVAC contractor perform a load calculation.
System type: Conventional hydronic systems warm a room
through baseboard units located along the outside wall or under
windows to counteract chilly downdrafts. Baseboard tubing
continues to disperse warmth even after the hot water has
stopped flowing. For different temperatures in different living
spaces, choose zoned heating.
Service after installation: To ensure the boiler will provide
comfortable heat on demand for many years, select a licensed
contractor for after-sale support. Ask for written estimates and
references before you sign a contract
Natural Gas Hydronic Heating SystemsHydronic systems circulate hot water or steam
throughout homes Older systems use steam and
radiators to give off a radiant heat while newer systems
send hot water through baseboard units or piping in
the floor to produce both radiant and convection heat.
They come in a wide range of sizes and efficiencies
and need venting: atmospheric venting for lower-
efficiency models; induced draft or sealed combustion
for higher-efficiency units
Higher-efficiency boiler units with secondary heat
exchangers, known as condensing systems, also
require special piping and a drain.

Sizing: Your licensed contractor can determine the
appropriate heater capacity based on the size of your
room, insulation value of your windows, walls and roof.
Other Natural Gas Heating Systems
Ductless
Ductless heaters allow you to enjoy gas heat without adding
ductwork or a chimney. Easy-to-install, efficient direct-vent
models can be installed on any outside wall and can heat the
whole house. Vent-free models offer supplemental heat in a
single room or emergency heat during a power failure.
Combo
Heat your home and water with a natural gas water heater—
storage or tankless. Simple and inexpensive to install—there
are no vertical flues and only one gas line is needed Direct
venting is required, but the air handler can be installed where
convenient. The home is heated when hot water is pumped
through the coil in an air handler

Natural gas fireplaces simulate the look of real wood—with none
of the hassles The “logs” are available in a variety of wood styles
A burner module creates the flames, which dance and flicker with
golden hues Some units even recreate the look of glowing embers
beneath the logs. Safety is built in: the main burner on most units
will not light if combustion cannot take place safely. Vent-free units
contain an oxygen depletion sensor to turn off the unit if the oxygen
level falls
Use as a Source of Heat
Some natural gas fireplace products can be used for substantial
zone heating. Look for the product descriptions “vented natural gas
fireplace heater” or “vent-free room heater.” Products certified as a
“vented natural gas fireplace” are not designed to heat, but offer the
ambiance of a beautiful fire
More Realistic Than Ever
Today, they don’t just look more like wood fireplaces, they can sound
and smell like them, too, with smoky incenses and crackling sounds
available. They can even improve on reality, with catalytic filters that
cleanse the air
heatnglo com(see our ad on page 45)
Natural Gas Fireplace Products
Vented Log Sets
Vented log sets offer the lowest initial cost and simplest
installation—right into existing wood-burning fireplaces.
Vented through the flue, much of the heat is lost up
the chimney (as in wood fires), making them primarily a
decorative product. Also available in vent-free models
(See page 32).
Fireplace Inserts
Inserts are self-contained units that, when installed in an
existing fireplace, are efficient sources of supplemental
heat. They vent through the existing chimney as
long as an approved flue liner is installed. Controlled
combustion and ventilation improve heating capability.
Also available in vent-free models (See page 32).
28
Factory-Built Fireplaces
Factory-built natural gas fireplaces can be added
to most rooms—neither an existing fireplace nor a
chimney (in the case of direct-vent models) is needed.
They are complete units available in a variety of
configurations including see-through, corner models,
and peninsula units with three open sides. Great for
remodeling or new home construction, they are also
available in vent-free models (See page 32).
Freestanding Stoves
Freestanding natural gas stoves are self-contained
units that resemble old-fashioned wood burning stoves
They can take the place of an existing wood stove if
a special flue liner or natural gas vent is inserted into
the chimney Natural gas stoves are available in both
contemporary and traditional styles, in an array of
colors, and most have a fire-viewing area. Natural gas
stoves can contribute significant heat to the room or
the entire house and are also available in vent-free
models (See page 32).
Fireplace Venting TechniquesHearth products are vented in three ways: natural draft,
direct-vent and vent-free
Natural draft products vent out through the roof by using a
relined masonry or metal chimney or newly installed “B-vent.”
Existing masonry chimneys must be relined to ensure proper
draft and prevent harmful condensation.
Direct-vent products can be vented vertically or horizontally
so a conventional chimney is not needed, providing greater
location flexibility. Direct-vent uses two pipes (often one
inside the other) to both draw the air needed for combustion
and vents the gases outdoors. Remember, these units cannot
be located too far from building exteriors. Some units will
circulate room air around the fireplace to provide additional
convective heating
3130 31
Manufacturer
heatnglo com(see our ad on page 45)
Vent-free products draw air from the inside of the home and burn
so efficiently that there is no need for venting. They are the optimal
choice as an additional heat source Vent-free units should not be
installed in bedrooms, bathrooms or other confined spaces, and are
for occasional, attended and supplemental use only. Because vent-
free natural gas hearth products are certified as vent-free space
heaters, they are required to have an oxygen depletion sensor
(ODS). Some models are available with a built-in catalyst to further
reduce the emission of combustion products. Washington Gas
recommends that consumers strictly adhere to the manufacturer’s
operating instructions.

WashingtonGas com Washington Gas recommends you consider
products that are design-certified by a nationally-recognized
laboratory that tests to American National Standards Institute
(ANSI) standards.
Choosing a Dealer/InstallerGet a free estimate and compare the total cost of the models you
are considering. Total cost includes the fireplace product price,
including any accessories, installation cost and operating and
maintenance costs
We recommend choosing your dealer on more than lowest price
alone Ask if they install and service their products. If not, ask if
they arrange for a professional to handle installation. Then, choose
the dealer you can trust to provide the greatest overall value.
Use a licensed installer who will provide you with a copy of all
necessary permits to show your fireplace is in compliance with
local codes and regulations Your installer should arrange for
inspection by the county or city that issued the installation permit
for the work (See page 83). After installation is complete, request
a review of how to operate the product and all recommended
service requirements.

Important Safety Requirements for Natural Gas Fireplaces 1 Installation of a vented gas log set must be in a wood-burning vented
fireplace that has a working flue constructed of noncombustible materials
and meets proper clearances to combustible materials.
2. If combustion air is drawn from the home (conventional venting or vent-free
products), at least 50 cubic feet of room volume is required for every 1000
BTUs of burner input. This applies to the sum of all equipment burners
drawing combustion air from the space.
3. When a vented natural gas log set is installed, a special damper clip must
be affixed to the chimney damper to prevent the damper from closing
completely (except for vent-free products).
4. A fireplace screen or glass door should be installed with all vented natural
gas logs and fireplaces.
5. When using an existing chimney for venting, a flue liner may be needed. In
addition, you should plan to have your chimney cleaned before installation.
6. In Washingtong Suburban Sanitary Commission (WSSC) jurisdictions
(Montgomery and Prince George’s Counties), a carbon monoxide (CO)
alarm is required in homes where a vent-free fireplace product is installed.
Aside from WSSC, this is recommended from a safety stand point.
7. Installation of natural gas logs in a prefabricated fire box that is not UL
listed for gas is prohibited.39

Water heating is the second largest use of energy in the home It’s
nice to know that high-efficiency natural gas water heaters heat
more water per hour—and do so up to twice as fast—as electric
water heaters. Choose from two types of natural gas water
heaters—storage, the most common type, or the newer, even more
efficient, tankless water heaters.
Storage Water Heaters
Storage water heaters range in size from 20 to 80 gallons, and
usually consist of a steel tank lined with glass or another anti-
corrosive material. Since hot water is lighter than cold water, hot
water leaves from the top of your water heater whenever someone
turns on a hot water tap. To replenish the tank, unheated water
enters from the bottom and is heated by a thermostat-controlled gas
burner. The burner will also turn on if the temperature in the tank
falls below a certain level, so that hot water will always be available
when a tap is turned. A relief valve protects against temperature
or pressure that is too high for the tank. Because installation is
relatively simple, they’re a good choice for homes converting to a
natural gas water heating system They offer the homeowner many
installation and location choices
Tankless Water Heaters
Making the right choice STORAGE WATER HEATERS
Capacity: While many consumers choose models based on
tank size, the first-hour rating (FHR) is actually more important.
FHR, required by law to appear on the Energy Guide label, is
the measure of how much hot water the heater will deliver in
an hour. So you don’t buy a water heater larger than you need,
estimate your household’s hot water needs and shop for a
water heater with an FHR in that range
Efficiency: The energy efficiency of a storage water heater is
indicated by its “Energy Factor” (EF). The higher the EF, the
more efficient the water heater
Cost: While it may be tempting to buy an inexpensive water
heater, the least expensive water heaters are often the most
expensive to operate. A high-efficiency water heater may cost
a little more, but reduced operating costs will more than make
up for the higher outlay. Use the Energy Guide label to help you
choose an energy-efficient heater
4746
Tankless Water Heaters
With a tankless water heater, the burner heats water only when
there is a demand for hot water Since there is no constant heating
and re-heating of stored hot water, no energy is wasted; the amount
of energy used is always proportional to the volume of hot water
being used. When the hot water tap is turned off, the system
shuts down. This translates directly to operational dollar savings
and reduced impact on our environment. Yet, hot water arrives as
quickly as with a storage heater, and never runs out (when sized
appropriately for your home). Tankless water heaters are designed
to last for 20 years, and because they are smaller than tank units,
they are perfect for homes where space is limited.
Condensing Storage Water Heaters
Gas condensing water heaters work much like other gas water
heaters. However, in lieu of venting the combustion gases, these
gases are used to reheat the water, making these waters heaters
more efficient

Making the right choice TANKLESS WATER HEATERS
A different set of considerations are involved in choosing a tankless
heater. A qualified contractor can help you decide both whether a
tankless water heater is suitable, and which one would be best for you.
Flow rate and simultaneous water usage needs: While tankless water
heaters can provide an endless supply of hot water, they can be limited
as to how much hot water can be produced at any given time. To find
the unit best for you, you’ll need to determine how much hot water
flow is required. It is important to have the unit sized properly. Some
applications may require multiple units to work properly.
Gas line sizing: Have your qualified contractor ensure your gas line is
sized properly; tankless water heaters draw many more BTUs than a
storage water heater and may require higher gas pressures.
Combustion air requirements: These apply only to indoor
installations where air is drawn from the room where the water heater
is installed. Some manufacturers offer only direct-vent units, which do
not require internal combustion air.
Venting your gas water heater To remove combustion by-products, natural gas water heaters must be vented to the outdoors in one of the ways below
Atmospheric venting is the most common, and simply lets the gaseous by-products, which are warmer than the surrounding air, rise naturally through a vertical metal vent pipe or masonry chimney. Fans or other mechanical boosters are not needed, keeping installation and operating costs down.
Direct-vent or horizontally-vented water heaters can be used when vertical chimneys or flues are not available or would be more expensive to install. The vents go directly through an outside wall, and also can bring combustion air to the burner. Most of these units require zero clearance at the sides and rear, so they can be installed in a small area
Fan-assisted or power-vented gas water heaters use an electric fan or blower to push out combustion gases. This type of venting allows gas water heaters to be installed as far as 40 feet away from an outside wall and in homes without existing vertical vents. The flue or vent pipe can be hidden behind walls and cabinets Other gas equipment installed with the water heater can use the same power venting system.
Note: In general, the water heater should be installed so the vent length is as short and straight as possible. Some models can be vented up to 41 feet, vertically or horizontally, while other models can be vented as far as 100 feet or more

NATURAL GAS PRODUCTS EXTEND THE ENTERTAINING SEASON
MAKE THE GREAT OUTDOORS EVEN GREATER
Create a terrific getaway right in your own backyard with these natural gas outdoor products. Natural Gas Grills Get all the advantages of outdoor cooking without the mess, expense or long preparation time of charcoal. And unlike propane tanks, which always seem to run out of fuel just as hungry guests arrive, a direct connect to your home’s gas line means an uninterrupted fuel supply.
Start grilling in an instant, with precise cooking control. Natural gas grills heat up fast, and their precise temperature control gives you more flexibility than charcoal or propane. Cook at a constant temperature without having to tend the fire or check propane levels.
Special features such as flavorizer bars, side burners, rotisseries, multi-level cooking, flip-up side tables and food warmers let you create exactly what you’re looking for in a grill. Locate it permanently on your deck or patio or choose a “quick-connect” hookup that makes it easy to move the grill when not in use
With proper maintenance, safe, clean-burning natural gas grills will last for years, saving you the expense of charcoal and lighter fluid or propane. And cooking on a grill keeps your kitchen cooler, reducing the demand on your air conditioning when it’s warm outside
57
58
Making the right choice Grill Size: Make sure your grill fits safely and conveniently in
your outdoor area, especially if you are considering permanent
installation to your existing home gas line.
Ignition: Push button igniters produce a spark with each push;
knob igniters emit two or three sparks per turn.
Burners: Separate burners allow you to control heat better
than just one burner; most grills have at least two Check that
your burners are proportional to the grill cooking area for more
efficient and even cooking
Heat Distribution: To better distribute heat, use lava rocks,
ceramic briquettes, metal plates and metal bars. Consider a grill
that funnels grease away from the burners to be vaporized for
enhanced charbroiled flavor while reducing drip flare-ups.
Installation and Mounting Types: “Quick-connect” hookups
let you move the grill when you’re not cooking. Post or built-
in type grills connect directly to your home’s gas line and are
permanently located. For those, look for a grill that will stand up to
the elements
Assembly: If assembly is required, ask if your dealer offers
assembly services
Patio Heaters
Get gentle, sun-like warmth with natural gas patio heaters. Infrared
burners, emitter screens and reflector domes direct uniform, radiant heat
downward to warm people and objects, not the air in-between. While they
can operate effectively in exposed areas, patio heaters are more efficient
in wind- and weather-protected areas.
Making the right choice Size: The warmth from a patio heater can cover a 12- to 25-foot area.
Choose a model that’s best suited to how you’ll be entertaining
Location: Near cooking and eating areas or by a pool or spa—
where gas piping often already exists—are popular choices.
Burners and Ignition: Models with adjustable burners and piezo
ignitions light with the turn of a knob and allow you more control
over heating output. Individual remote control switches provide
instant starting
Safety: Some models have shut-off systems that automatically turn
the unit off in winds of 10 mph or more.
Installation and Mounting Types: Options include permanent post,
portable post (with a flexible gas line and quick connection) and
suspended mountings, great for limited space because they can be
permanently mounted out of the way. 59
61
Outdoor Lights
Get dependable security and the safety of non-shadowed
illumination from natural gas lights—all without electricity.
They cast light equivalent to a 60-watt bulb, and don’t attract
insects. With fuel-saving features built in, optional dimmers
or electronic ignitions make them even more cost efficient
Weatherproof and sturdy, they require little maintenance.
Making the right choice Mounting Types: Mount on a wall, on your deck, or on a post on your patio.
Consider installing on the same gas line serving a pool/spa heater or gas grill.
Location: Consider lighting walkways, entryways and outdoor entertainment
areas, especially those with other natural gas products.
Style: From carriage lamps to tiki torches, outdoor gas lights come in many styles.
Burners: Mantles (a covering of refractory material) provide incandescent light
when placed over a flame. Standard gas lights with dual-inverted burner and
mantles provide maximum light. Other burner options include triple and quad
burners, or an open flame burner for a more natural appearance.
Ignition: For convenience, look for a gas light that has an electronic ignition
and can be turned on and off with a typical light switch. Models with automatic
reignite will relight if the flame is blown out
60
Pool and Spa Heaters
Get precise temperature controls from even the most basic models. Extremely
durable, they heat water quickly and economically. Automatic thermostats and timers
let you maintain a constant temperature or heat only as needed. Quick-connect
plumbing connections allow simple hookups to existing water and gas lines, while
automatic shut-off controls provide added safety. Self-diagnostic programs that give
service technicians detailed information are an example of available options.
Making the right choiceHeater Size: Don’t choose a smaller heater solely on initial costs. Because
it doesn’t have to work as long to heat the same size pool or spa, a larger
heater may be more economical than a small heater Tell your dealer the
pool size and the water temperature desired during the coolest month you
plan to use it. For a spa heater, gallons and preferred heat-up time are the
deciding factors
Ignition and Burners: A standard electronic ignition system activates the
pilot light only when necessary. A millivolt ignition offers matchless ignition.
Stainless steel burners offer greater reliability and longer life
Maintenance: Consider models with easy serviceability to the igniter and
encapsulated controls that can extend heater life by maintaining a dryer,
cooler environment Annual maintenance is recommended
Conservation: Use a pool or spa cover to reduce heat loss and shield your
pool from the wind, as wind lowers temperatures significantly.

Outdoor Fire Pits and Campfires
Enjoy your deck or patio on chilly spring afternoons thanks to the warmth of a
natural gas fireplace. Select from a firepit, chiminea or built-in outdoor fireplace
to keep you warm.
No fuss. No mess. No smoke. Easy to start with the simple turn of a knob—
thanks to a permanent connection to your home’s gas line—there’s no chopping
and hauling firewood. When you’re done, just turn it off and there’s no clean up.
Protective covers guard against the elements and make campfires even easier
to maintain. Place one anywhere you can connect to a natural gas source, even
on a wood deck. The controlled flame is safe and won’t kick out sparks; and
there’s no wood-burning air pollution or forest depletion.
Create your own look There are a variety of stainless steel burner systems
available in several sizes, BTU outputs and different ceramic fiber logs.
Your campfire can also be customized using rock, brick, stone or fabricated
surrounds. You can even have a built-in outdoor fireplace.
Making the right choiceLocation: Consider the type of surface your outdoor fireplace or campfire will
sit on and how much room is around it
Styles and Construction: Outdoor fireplace styles are endless. Choose from
full-size, built-in fireplaces, the charm of chimineas, the rustic feel of firepits.
Log Types and Options: Logs are crafted to simulate the look of real wood and
are available in a variety of wood types. Many are split and charred for added
realism. Additional outdoor fireplace and campfire options include remote
control, wall mounted on/off switches, safety screens and grilling capabilities.
Surrounds: Build your own campfire surround or choose from prefabricated
surrounds, such as small cast iron bases, for use in smaller backyards.
Burners: High-input burners made of ceramic or stainless steel provide instant
heat to the surrounding area Models with variable flame control allow you to
adjust your fire and turn it on and off in an instant
Ignition: Electronic ignitions enable an easy, instant start with the push of a
button or turn of a knob Smaller models may have a manual ignition Some
models have safety shut-off valves and automatic reignite that will relight if the
wind should blow the flame out
Maintenance: If you have a built-in fireplace or campfire permanently installed
to your gas line, consider using a fireplace cover to protect it from the elements.
6564
See all your choices in person
Get an in-person look at all the different outdoor products discussed
above at the participating dealers listed on page 65. While there,
ask about warranties and ease of replacement part purchase and
installation. Look for design-certification from a nationally-recognized
laboratory that tests to American National Standards Institute (ANSI)
standards. Compare the total cost of any models you are considering
by including the price of desired accessories, installation, operation
and maintenance. Choose a reliable dealer you trust to provide the
greatest overall value — not just the lowest price.
Inquire about available financing options the dealer may offer. Ask if
they assemble, install and service the products they sell. If not, ask
if they will arrange or recommend a professional for installation or
service Get a written estimate and check references before signing
a contract
Make sure your outdoor product is in compliance with local codes and
regulations by getting a copy of all necessary permits. Any licensed
installer will gladly provide you with a copy. Your installer should also
arrange for inspection by the county or city that issued the installation
permit for the work. See page 83 for more information.

Serious chefs prefer natural gas. It’s energy efficient, turns on and off instantly,
and offers even heat and precise temperature control.
Natural gas cooking products come in all sizes and configurations, from the
familiar freestanding range with a cooktop and oven to built-in cooktops
and ovens, separated based on the layout of your kitchen. Drop them into
countertops or islands or between cabinets. Add an indoor gas grill as part of
the range or as a freestanding unit, too.
While true commercial ranges are not recommended for home use because
of their high heat output, many professional-style ranges are now available for
home installation. With extra insulation and other home safety measures, they
feature multiple burners and ovens.
To save energy, most new natural gas cooking products use electronic or
spark ignition rather than a continuously burning pilot light. Although an
exhaust system may not be required by code, exhaust fans eliminate the
normal by-products of cooking such as steam, smoke, grease and heat—and
indoor gas grills always require an exhaust system. You can use a traditional
overhead exhaust fan that runs through a wall or ceiling; some products
can even use a “downdraft” system. Downdraft exhausting is often used on
islands, avoiding a traditional oven exhaust hood in the center of the kitchen.

Making the right choiceSize: Most free-standing ranges are 30 inches wide, but
20-, 24-, 36- and 40-inch wide models are available. Drop-in
or slide-in ranges are usually 30 inches wide but may be
available in other widths. Cooktops come in 30-inch and
36-inch widths. Professional ranges are available in widths
from 24 to 60 inches, with varying heights. Special options
include sealed or removable burners, cleaning features,
convection ovens and heavy-duty burner grates
Cleaning and controls: Cleaning methods include
standard, continuous- and self-cleaning. Try out the
controls—are they easily understood and easy to reach
and use?
Exhaust system: Keep exhaust placement in mind as
you shop and consult with an appliance professional to
determine compatibility of the ventilation and the cooking
surface
Warranties and certification: Compare warranty and service
arrangements and consider design-certified models tested
to national standards by a nationally-recognized laboratory.

Making the right choiceLimited space: Compact natural gas dryers require only about
five square feet of space. Often a stackable washer/dryer unit
may provide the best fit for small laundry rooms.
Venting: Dryers can be vented from the side, back or bottom.
Capacity: Regular/large drum size dryers usually have a drum
volume of 5 5 to 7 cubic feet to easily handle average family
loads. In addition to large loads, extra-large drum sizes (volumes
up to 8 cubic feet) are designed to handle very bulky items such
as comforters
Certification: Models must be design-certified and tested to
national standards by International Approval Services or another
nationally-recognized laboratory.
Unlike electric, natural gas dryers provide full heat instantly for faster
drying, so the more laundry you do, the more you’ll want to choose
natural gas Today’s natural gas dryers use electronic ignition systems
(instead of a continuously burning pilot light) for additional savings and
energy conservation. And when natural gas dryers shut off, the heat
stops immediately.
Natural gas clothes dryers range in size from 24 inches to 29 inches
and generally come in three different drum sizes: compact, regular/
large and extra large. Almost all are front-loading with doors that can
swing down or to the left or right
71
Typical dryers have three to six different cycles for the desired
dryness and for different fabrics Some dryers also offer a feature
that continues to tumble clothes periodically to keep wrinkles
from setting in An adjustable end-of-cycle signal is available on
most dryers
KEEP YOUR HOME RUNNING WHEN THE LIGHTS GO OUT
POWER YOUR HOME WITH NATURAL GAS
Unforeseen events like extreme weather and construction
accidents can interrupt electrical service. If your electricity does
go out—at any time—a natural gas standby generator system will
still provide all the power you want. And for people who work from
home, reliable, on-site power generation is a must.
Permanently installed outdoors—much like an air-conditioning
unit—generator systems typically include an automatic transfer
switch, the generator, battery charger and distribution panel.
The transfer switch continually monitors utility power. If there’s
a failure, it starts the generator and transfers your home’s
electrical loads. When utility power resumes, the transfer switch
automatically reverses the process.
Choose one of three power distribution scenarios: essential
loads, managed loads or whole house. Essential Loads supplies
electrical power during an outage only to devices you’ve selected.
Examples are: furnace, lighting, sump pump, refrigerator/freezer,
security system and garage door opener. Whole House provides
generator power to all devices in your home, as if they were
drawing normal utility power.
73
Making the right choiceDetermining the proper size for your generator is critical. Estimate your
power needs with the help of a qualified contractor. (Note: Electric
power is measured in watts and 1,000 watts is called a kilowatt.)
Gas line sizing: Have your qualified contractor ensure your gas line is
sized properly; generators draw more BTUs and may require higher
gas pressures.
Compare quotes: Purchase and installation prices may vary
considerably. Compare the warranty and service package for
several models. Get written installation quotes from several licensed
contractors along with references and a contract. Be sure that the
contractor you choose has a proven track record working with standby
power generators and can provide you with immediate parts and
service. Keep in mind that you rarely want to make your decision based
on up-front price alone.
