• 3 X 5 inch reduces to 2 X 4 inch

• New tankless can go in an old

condensing vent system for

replacement if needed

• New install can have smaller, lighter,

less expensive concentric• Single penetration through the wall,

reducing install time and costs

• Simple positive-fit components for secure

connection

• Joint seals that expand and contract with

weather to prevent damage

• Ease of assembly and adjustment

SENSEI Series Concentric Venting

• Check valve integrated between the fan assembly and combustion chamber

• Creates additional venting solutions• Additional freeze protection• Stops backdraft of exhaust with common vent

Integrated Check Valve

• Room air can be used for combustion

• Unbalanced zones – Snorkel, T, many options

Operational Performance

Turbo Fan- Feeds burner with gas/air mixture- Provides longest venting options

by any tankless manufacturer- Manufactured by Rinnai

Switching Venturi- Provides consistent mixture of air

and gas to burner- Self-compensates with low or

fluctuating gas pressures- Manufactured by Rinnai

Fiber Mesh Premix Burner- Provides even flame

distribution for optimal performance at any demand

- Manufactured by Rinnai

Primary Stainless Steel HEX- Resists the corrosive natureof the condensate, which occurs early in the high-efficiency combustion process. - Manufactured by Rinnai

Zero Governor Gas Valve- Optimizes combustion by

consistently delivering gas and air- Manufactured by Rinnai

Performance All components working together provide the best combustion performance possible

Integrated Flue Check Valve- Prevents backflow of

combustion gases in common vent systems

A parameter adjustment can be made for greater hot water flow (up to 11

GPM) in areas with low delta T. Maximum flow rates may vary based on set

temperature, and altitude

Increased Water Flow

Natural 3.5 in. w.c. - 10.5 in. w.c.

Propane 8.0 in. w.c. - 13.5 in. w.c.

The gas and air are premixed in the venturi

before delivery to the burner assembly.


• The unit will self compensate (de-rate) in

areas with fluctuating or low gas pressures,

to optimize performance.

• Minimizes errors due to poor gas pressures

or air flow

Lower Minimum Gas Pressure

• Integrated MC-91-2 controller in

all water heaters. It is located

behind the front panel on external

units

• Cascade systems

• Residential units are linked with

EZ connect or MSB accessories

• Commercial units have onboard

cascade controls built into the

PCB (up to 24 units)


Operational Performance - Recirculation

• Two models available with

• RUR199 and the new smaller RUR160 with by-pass mode

• Select the accessory controller for desired recirculation

Serviceability

Quick Change Components

Designed for Serviceability

Every component was designed to be

removed in under 10 minutes

• Heat exchanger

• Water flow servo

• PCB (Data Transfer)

• Turbo Fan

• Etc.

Stainless Steel Primary Heat ExchangersThe SENSEI combustion system has several

new components working together in harmony.

• Zero governor gas valve

• Switching venturi

• Turbo fan

• Premix burner

The entire burner surface area comes on at

low inputs rather than a staged burner.

This combustion system is more efficient at

lower inputs and will produce condensate

earlier in the combustion process.

Stainless Steel Primary Heat ExchangersBecause of the potential for condensate at a low

inputs, Rinnai chose stainless steel on the

Primary Heat Exchanger

To further optimize durability:

Tubes are made from 444 SS which is superior for

corrosive properties, and has a lower coefficient of

expansion, and better thermal conductivity. The body

is also made from 400 series SS.

• The tube design incorporates a 1.0 mm wall

thickness vs. .8 mm tubes for extra durability.

• Fluorine gaskets are used at the joints rather than

EPDM for durability and heat resistance

Internal Insect Trap

• Internal insect trap

helps keep the

combustion system

clean

• Easy to remove

• Minimizes the need

and time to service

Intake vent screen

• Intake vent screen included with all units

• Use for room air or 2 pipe venting systems
