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.

The reason for having the air intake opening either near the floor or being provided with a duct terminating near the floor is to allow cooler outside air to enter the boiler room. If only one opening was provided, heat build-up in the boiler room would reduce the density of the air which, being lighter than cold outside air, would escape
