Note: All metric values are calculated from the Imperial values and are only approximate values.
1. Fuel Input is based on the high heat value of gas. Burner efficiency = 83%. Allowable supply gas pressure is 7”-10.5” wc.
2. Power consumption does not include external pumps or cooling tower fan motors.
3. “Width” dimension does not include Junction Box.
4. Specifications are all based upon water in all fluid circuits and fouling factor of 0.0005 ft²-hr-°F/Btu.
5. Pressure Loss ratings are +/- 10%.
6. Minimum Cooling Water flow is 100%.
