General Information N/A Up to 96% Efficient
  1. The quiet, brushless DC blower prepurges the submerged combustion chamber for 8 seconds and turns off.
  2. The hot surface igniter is energized and glows red hot.
  3. The blower turns on, precisely mixing air and gas for combustion. The mixture is forced through the metal fiber 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.
  4. The combustion chamber wall efficiently transfers high temperature heat from the flame to the water.
  5. The blower pushes hot combustion gases through the spiral coil, which scrubs the remaining heat from the hot gases.
  6. 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.
  7. Combustion gases are vented through PVC, CPVC or ABS plastic pipe.
  8. 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.
Woven Metal Burner N/A
  • Low NOx emissions
  • Resistant to thermal and mechanical shocks
  • Woven material provides even heat distribution
  • through uniform combustion
  • Protects from flashback
Whisper Quiet Blower N/A A high capacity, quiet, brushless, DC motor is combined with an integrated gas/air control safety system resulting in excellent combustion with flexible venting options.
Easy to Install and Service N/A
  • All gas valve and blower adjustments are factory preset
  • High altitude installations do not require adjustments or derating in the field
  • When optional concentric vent is used, only one hole is cut in the wall or roof
  • A self-diagnostic control automatically monitors all critical water heater functions and indicates the status of each using a flash code sequence
Features N/A
  • Sealed Combustion with Woven Fiber Premix Burner
    Metal fiber burner is designed for homogenous 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. Meets Low NOx requirements for California and Texas.
  • Whisper Quiet Operation
    Ultra quiet blower and burner minimize noise. Requires 120 volt 60 Hz power supply. Draws less than 5 Amps.
  • Power/Direct Vent Using 2" or 3" Plastic Pipe
    Direct vents up to 120' using PVC, CPVC, or ABS, either Thru-the Wall or Thru-the-Roof. Optional concentric vent kit available for use Thru-the-Roof or Wall.
  • "Plug-and-Play" Technology
    No special adjustments are required at initial startup. Connect air inlet, exhaust outlet, water, electricity, and gas. Set the temperature and the system functions properly.
  • External Temperature Adjustment Knob Up to 185 ºF.
  • 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.
  • Multiple 1 "Tank Connections.
  • Brass.
  • Certified to Current Edition of ANSI Z21.10.3/CSA 4.3.
