for natural gas.
Flue gas temperatures measured as gross values at 68ºF / 20 ºC combustion air temperature.
The details for partial load refer to an output of 30 % of rated input. Calculate the flue gas mass flow rate accordingly when the
partial load differs from that stated above (subject to the burner mode).
