Notes:
  1. Fuel input is based on the Higher Heating Value of gas. Burner efficiency = 83%.
  2. Pressure Loss ratings are +/- 10%.
  3. Power Consumption does not include external pumps or cooling tower fan motors.
  4. "Height" does not include level bolts, but "Height with Vent Cap" includes both vent cap and the level bolts.
  5. "Depth" does not include Junction Box. Add 3.9" to Depth Dimension to include Junction Box.
  6. Specifications are based upon water in all fluid circuits and fouling factor of 0.0005 ft²-hr-°F/Btu.
