• 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.
Operational Performance
• 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)

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
