Tech Data is based on Natural Gas with a calorific value of 970 Btu/ft3 and a methane No. >80.

The Tech Data is based on standard conditions in accordance with DIN ISO 3046-1. Atmospheric pressure: 14.5 psi or 328 ft above sea level, Air Temperature: 77 deg F, Relative Humidity: 30%
Tolerances: Fuel Consumption + 5%, Thermal Output +/- 8%

Sound Level Rating applies to Indoor Enclosed Module. Sound Level Rating applicable to Outdoor Enclosed Module is 65 dB(A) +/- 3 @ 10 m Heat transfer data is based on 40% antifreeze.
