from the desired indoor temperature.
Burner Performance Table
2. Values shown in above MBH Input Table are based on
-40° F Inlet Temperature. MBH input shown on unit
rating plate will be corrected for actual air density.
3. Natural gas units are limited to 130° F temperature
rise, propane units are limited to 100° F temperature
rise.
