    As a "rule of thumb," 1 ft 3 of natural gas theoretically requires 10 ft 3 of air for complete combustion at 60°F and 14.7 psi under perfect conditions. 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
