Polaris® High-Effciency
Residential Gas Water Heater
The perfect choice for combi systems
Polaris® has a high grade 444 stainless steel tank with brass connections for years of dependable, trouble-free service – no anode required. A submerged combustion chamber with spiral flue provides up to 96% thermal efficiency and ultra-low standby heat loss of approximately 1%.
SEALED COMBUSTION WITH WOVEN FIBRE PREMIX BURNER
- Metal fibre burner is designed for clean combustion in high-intensity blue flame mode. Manufactured of refractory steel that resists corrosion. Excellent resistance to thermal and mechanical shock, even at extreme temperatures. Uniform combustion provides excellent heat transfer.
WHISPER QUIET OPERATION
- Ultra quiet blower and burner minimize noise. Requires 120 volt 60Hz power supply. Draws less than 5 Amps.
POWER/DIRECT VENT USING 2” OR 3” PLASTIC PIPE
- Direct vents up to 120’ using ULC S636 PVC or CPVC pipe either Thru-the-Wall or Thru-theRoof. Optional concentric vent kit available for use Thru-the-Roof or Wall.
PLUG AND PLAY TECHNOLOGY
- No special adjustments are required at initial start up. Connect air inlet, exhaust outlet, water, electricity, and gas, set the temperature and the system functions properly.
SELF-DIAGNOSTIC CONTROL SYSTEM
- Three external LED lights indicate operational status of water heater. Microprocessor monitors nine critical functions. An LED troubleshooting light, visible through view port, signals heater operation status.
FULL SERVICEABILITY FROM THE FRONT
- Removal of two front-located access panels exposes all serviceable components. Modular components are easily removed.
ENERGY STAR® QUALIFIED
- PR100-34-2NV model meets ENERGY STAR® requirements

UP TO 96% EFFICIENT
- The quiet, brushless DC blower prepurges the submerged combustion chamber for 8 seconds and turns off.
- The hot surface igniter is energized and glows red hot.
- The blower turns on, precisely mixing air and gas for combustion. The mixture is forced through the metal fibre burner and is ignited by the hot surface igniter. A blue flame is evenly distributed across the entire burner, resulting in clean combustion with low nitrous oxide emissions.
- The combustion chamber wall transfers high temperature heat from the flame to the water.
- The blower pushes hot combustion gases through the spiral coil, which scrubs theremaining heat from the hot gases.
- As combustion gas exits the bottom of the spiral coil, it is barely warm to the touch. Up to 96% of the heat from the flame is transferred to the water.
- Combustion gases are vented through ULC S636 plastic pipe.
- Condensation formed by cooled combustion air is captured by a condensate trap and drained through a drain line.
THE QUIET WAY TO EFFICIENTLY HEAT WATER
An ultra quiet radial blower is combined with a submerged burner for whisper quiet operation. Indicator lights illuminate when the power is on and when the igniter and burner are operating.
THE BEST CHOICE FOR HOT WATER
Polaris is ideal for large homes. For dishwashing, showers, baths, clothes
washing, or hot tubs, Polaris is the best choice. Polaris models heat up to
255 GPH at a 90°F/50°C temperature rise, compared to 41 GPH for standard gas
water heaters.
FORCED AIR HYDRONIC HEAT
Polaris can be used to combine an air handler for comfortable forced air hydronic space heating with potable hot water. Hot water is circulated through a coil in the air handler. Air from the home is warmed as it is blown across the coil. Warmed air is returned to the home through air ducts. With up to 199,000 BTUs, Polaris can heat most homes, large or small.
RADIANT HYDRONIC HEAT
Polaris works great for homeowners who prefer radiant hydronic heat. With radiant floor hydronic systems, potable hot water is circulated through tubes under the floor. The floor absorbs heat from the tubes and radiates it into the room. With radiant baseboard heat, potable hot water is circulated through finned tube baseboard. Heat rises from the baseboard heaters, warming the home. All water components must be approved for use with potable water.
For propane, substitute “P” for “N” in the model number. 3” Concentric Vent Part #6911089 or 2” Concentric Vent Part #6911088. Specifications are subject to change without notice in accordance with our policy of continuous improvement. Input, output and recovery may vary depending upon air inlet and exhaust outlet installations. Length and number of bends in inlet and outlet pipes may reduce input and output. Consult installation, operation and service manual for details. Dimensions on all charts shown in inches. *1/2” gas supply line can be used for up to 150,000 BTU units, units over 150,000 BTUs require a 3/4” gas supply line.
