AIR FORCOMBUSTION ANDVENTILATION

Today’s homes are built more energy effi-cient than ever. New materials, increasedinsulation, and new construction methodshelp reduce heat loss in homes. Home ownersweather strip and caulk around windows anddoors to keep the cold air out and the warm airin. During heating months, home ownerswant their homes as airtight as possible.

While it is good to make your home energyefficient, your home needs to breathe. Freshair must enter your home. All fuel-burningappliances need fresh air for proper com-bustion and ventilation.

Exhaust fans, fireplaces, clothes dryers, andfuel burning appliances draw air from thehouse to operate. You must provide ad-equate fresh air for these appliances. Thiswill insure proper venting of vented fuel-burning appliances.

Confined Space and UnconfinedSpaceThe National Fuel Gas Code, ANS Z223.1defines a confined space as a space whosevolume is less than 50 cubic feet per 1,000Btu per hour (4.8 m3 per kw) of the aggre-gate input rating of all appliances installedin that space and an unconfined space as aspace whose volume is not less than 50cubic feet per 1,000 Btu per hour (4.8 m3 perkw) of the aggregate input rating of allappliances installed in that space. Roomscommunicating directly with the space inwhich the appliances are installed*, throughopenings not furnished with doors, are con-sidered a part of the unconfined space.

This heater shall not be installed in a con-fined space or unusually tight constructionunless provisions are provided for adequatecombustion and ventilation air.

* Adjoining rooms are communicating onlyif there are doorless passageways or ventila-tion grills between them.

PROVIDING ADEQUATEVENTILATIONThe following are excerpts from NationalFuel Gas Code, NFPA 54/ANS Z223.1, Sec-tion 5.3, Air for Combustion and Ventilation.

All spaces in homes fall into one of the threefollowing ventilation classifications:

1. Unusually Tight Construction

2. Unconfined Space

3. Confined Space

The information on pages 4 through 6 willhelp you classify your space and provideadequate ventilation.

Unusually Tight ConstructionThe air that leaks around doors and windowsmay provide enough fresh air for combustionand ventilation. However, in buildings of

PRODUCTFEATURESOPERATIONThis vent-free fireplace is clean burning. Itrequires no outside venting. There is no heatloss out a vent or up a chimney. Heat isgenerated by both realistic flames and glow-ing embers. When used without the blower,the fireplace requires no electricity makingit ideal for emergency backup heat.

SAFETY DEVICEThis fireplace has a pilot with an OxygenDepletion Sensing (ODS) safety shutoff sys-tem. The ODS/pilot is a required feature forvent-free room heaters. The ODS systemshuts off the fireplace if there is not enoughfresh air.

PIEZO IGNITION SYSTEMThis fireplace has a piezo ignitor. This sys-tem requires no matches, batteries, or othersources to light fireplace.

BLOWER ASSEMBLY(GA3750 & GA3650T SERIES)This fireplace accepts an optional blowerassembly. The GA3750 blower has a manualvariable control. The GA3650T bloweroperates thermostatically. The blowercirculates heated air from the fireplace intothe room. Use of blower is optional. SeeAccessories, pages 24 and 25.

WARNING: This heater shallnot be installed in a confined spaceor unusually tight constructionunless provisions are providedfor adequate combustion and ven-tilation air. Read the following in-structions to insure proper freshair for this and other fuel-burningappliances in your home.

unusually tight construction, you mustprovide additional fresh air.

Unusually tight construction is de-fined as construction where:a. walls and ceilings exposed to the

outside atmosphere have a con-tinuous water vapor retarder witha rating of one perm (6 x 10 -11 kgper pa-sec-m 2) or less with open-ings gasketed or sealed and

b. weather stripping has beenadded on openable windows anddoors and

c. caulking or sealants are appliedto areas such as joints aroundwindow and door frames, be-tween sole plates and floors, be-tween wall-ceiling joints, be-tween wall panels, at penetra-tions for plumbing, electrical, andgas lines, and at other openings.

If your home meets all of the threecriteria above, you must provide ad-ditional fresh air. See Ventilation AirFrom Outdoors , page 6 .If your home does not meet all of thethree criteria above, proceed to Deter-mining Fresh-Air Flow for FireplaceLocation on page 5.

DETERMINING FRESH-AIR FLOW FOR FIREPLACE LOCATION

Determining if You Have a Confined or Unconfined Space

Use this work sheet to determine if you have a confined or unconfined space.

Space: Includes the room in which you will install fireplace plus any adjoining rooms with doorless passageways or ventilation grillsbetween the rooms.

1. Determine the volume of the space (length x width x height).

Length x Width x Height = _________________cu. ft. (volume of space)

Example: Space size 22 ft. (length) x 18 ft. (width) x 8 ft. (ceiling height) = 3168 cu. ft. (volume of space)

If additional ventilation to adjoining room is supplied with grills or openings, add the volume of these rooms to the total volume ofthe space.

2. Divide the space volume by 50 cubic feet to determine the maximum Btu/Hr the space can support.

_________________ (volume of space) ÷ 50 cu. ft. = (Maximum Btu/Hr the space can support)

Example: 3168 cu. ft. (volume of space) ÷ 50 cu. ft. = 63.3 or 63,300 (maximum Btu/Hr the space can support)

3. Add the Btu/Hr of all fuel burning appliances in the space.

Vent-free fireplace ____________________ Btu/Hr

Gas water heater* ____________________ Btu/Hr

Gas furnace ____________________ Btu/Hr

Vented gas heater ____________________ Btu/Hr

Gas fireplace logs ____________________ Btu/Hr

Other gas appliances* + ____________________ Btu/Hr

Total = ____________________ Btu/Hr

* Do not include direct-vent gas appliances. Direct-vent draws combustion air from the outdoors and vents to the outdoors.

4. Compare the maximum Btu/Hr the space can support with the actual amount of Btu/Hr used.

_________________ Btu/Hr (maximum the space can support)

_________________ Btu/Hr (actual amount of Btu/Hr used)

Example: 63,300 Btu/Hr (maximum the space can support)

73,000 Btu/Hr (actual amount of Btu/Hr used)

The space in the above example is a confined space because the actual Btu/Hr used is more than the maximum Btu/Hr the space can support.You must provide additional fresh air. Your options are as follows:

A. Rework work sheet, adding the space of an adjoining room. If the extra space provides an unconfined space, remove door to adjoin-ing room or add ventilation grills between rooms. See Ventilation Air from Inside Building, page 6.

B. Vent room directly to the outdoors. See Ventilation Air from Outdoors, page 6.

C. Install a lower Btu/Hr fireplace, if lower Btu/Hr size makes room unconfined.

If the actual Btu/Hr used is less than the maximum Btu/Hr the space can support, the space is an unconfined space. You will need noadditional fresh air ventilation.

Continued

WARNING: If the area in which the heater may be operated is smaller than that defined as an unconfined spaceor if the building is of unusually tight construction, provide adequate combustion and ventilation air by one ofthe methods described in the National Fuel Gas Code, ANS Z223.1, Section 5.3 or applicable local codes.

Example:Gas water heater 40,000 Btu/Hr

Vent-free fireplace + 33,000 Btu/Hr

Total = 73,000 Btu/Hr

CONNECTING FIREPLACETO GAS SUPPLY


Figure 19 - Attaching Gas Lines Together

NOTICE: Most building codes donot permit concealed gas con-nections. A flexible gas line isprovided to allow accessibilityfrom the fireplace (see Figure 19).The flexible gas supply line con-nection to the equipment shutoffvalve should be accessible.

3. Route gas line (provided by installer)from equipment shutoff valve to fire-place. Route flexible gas supply linethrough one of the access holes.

Figure 17 - Gas Connection

* Purchase the optional CSA design-certi-fied equipment shutoff valve from yourdealer. See Accessories, pages 24 and 25.

CAUTION: Use pipe joint seal-ant that is resistant to liquid pe-troleum (LP) gas.

We recommend that you install a sedimenttrap in supply line as shown in Figure 17.Locate sediment trap where it is withinreach for cleaning. Install in piping systembetween fuel supply and heater. Locate sedi-ment trap where trapped matter is not likelyto freeze. A sediment trap traps moistureand contaminants. This keeps them fromgoing into fireplace gas controls. If sedi-ment trap is not installed or is installedwrong, fireplace may not run properly.

4. Attach the flexible gas line to gas sup-ply (see Figure 19). Check tightness offlexible gas line attached to gas regu-lator of fireplace (see Figure 19).


6. Replace log base assembly back intofireplace. Feed flexible gas line into fire-place base area while replacing log baseassembly. Make sure the entire flexiblegas line is in fireplace base area. Reat-tach log base assembly to fireplace withscrews removed in step 2.

Check your building codes for any specialrequirements for locating equipment shutoffvalve to fireplaces.

Apply pipe joint sealant lightly to malethreads. This will prevent excess sealantfrom going into pipe. Excess sealant in pipecould result in clogged fireplace valves.

INSPECTINGBURNERS

MAIN BURNERPeriodically inspect all burner flame holeswith the heater running. All slotted burnerflame holes should be open with yellowflame present. All round burner flame holesshould be open with a small blue flamepresent. Some burner flame holes may be-come blocked by debris or rust, with noflame present. If so, turn off heater and letcool. Either remove blockage or replaceburner. Blocked burner flame holes willcreate soot.

CLEANING ANDMAINTENANCE

WARNING: Turn off heaterand let cool before cleaning.

CAUTION: You must keepcontrol areas, burner, and circu-lating air passageways of heaterclean. Inspect these areas ofheater before each use. Haveheater inspected yearly by a quali-fied service person. Heater mayneed more frequent cleaning dueto excessive lint from carpeting,bedding material, pet hair, etc.

LOGS• If you remove logs for cleaning, refer to

Installing Logs, page 13, to properly re-place logs.

• Replace log(s) if broken or chipped(dime-sized or larger).

MAIN BURNERPeriodically inspect all burner flame holeswith the heater running. All slotted burnerflame holes should be open with yellowflame present. All round burner flame holesshould be open with a small blue flamepresent. Some burner flame holes may be-come blocked by debris or rust, with no flamepresent. If so, turn off heater and let cool.Either remove blockage or replace burner.Blocked burner flame holes will create soot.

CLEANING BURNERINJECTOR HOLDER ANDPILOT AIR INLET HOLEThe primary air inlet holes allow the properamount of air to mix with the gas. This pro-vides a clean burning flame. Keep these holesclear of dust, dirt, lint, and pet hair. Cleanthese air inlet holes prior to each heatingseason. Blocked air holes will create soot. Werecommend that you clean the unit every threemonths during operation and have heater in-spected yearly by a qualified service person.

We also recommend that you keep the burnertube and pilot assembly clean and free of dustand dirt. To clean these parts we recommendusing compressed air no greater than 30 PSI.Your local computer store, hardware store, orhome center may carry compressed air in acan. You can use a vacuum cleaner in theblow position. If using compressed air in acan, please follow the directions on the can.If you don't follow directions on the can, youcould damage the pilot assembly.

1. Shut off the unit, including the pilot. Allowthe unit to cool for at least thirty minutes.

2. Inspect burner, pilot, and primary airinlet holes on injector holder for dustand dirt (see Figure 42).

3. Blow air through the ports/slots andholes in the burner.

4. Check the injector holder located at theend of the burner tube again. Remove anylarge particles of dust, dirt, lint, or pet hairwith a soft cloth or vacuum cleaner nozzle.

5. Blow air into the primary air holes onthe injector holder.

Figure 42 - Injector Holder On OutletBurner Tube

6. In case any large clumps of dust havenow been pushed into the burner repeatsteps 3 and 4.

Clean the pilot assembly also. A yellow tip onthe pilot flame indicates dust and dirt in the pilotassembly. There is a small pilot air inlet holeabout two inches from where the pilot flamecomes out of the pilot assembly (see Figure 43).With the unit off, lightly blow air through theair inlet hole. You may blow through a drinkingstraw if compressed air is not available.
