Of course, this never happens, therefore burner combustion air fans may be sized for 25% excess air, in which case the fan would deliver 12.5 ft 3 of air per 1 ft 3 of natural gas. Additionally, many burner manufacturers will size the combustion air fans to provide sufficient air to operate properly up to 2,000 feet in altitude, in which case the sea level capacity will be increased by an additional 6 1/4%.

In general, the following formulas have been developed to determine the amount of air required for any boiler room with a package firetube boiler firing gas or oil fuels. 1. Combustion Air = HP* x 8 CFM/HP = 2. Ventilation Air = HP* x 2 CFM/HP = 3. Total Air Required = HP* x 10 CFM/HP = *HP refers to the total maximum boiler HP located in the boiler room.
