text: To ensure an adequate supply of air to the combustion zone, a number of factors need to be considered: the amount of air required for the combustion process itself; the amount of air required for ventilation and cooling within the boiler room; the effect of the venting system, including such items as vent hoods, barometric dampers, economizers, and automatic draft control systems; the effect of heat transfer-enhancing turbulators; the presence of exhaust fans, either in the boiler-room or in any part of the building that may be a source of air for the boiler/burner or alternatively may draw air from the boiler room; the requirements of various codes and standards; the presence of any other equipment, fuel-burning or otherwise, that may potentially consume air required for combustion; the effect of altitude; boiler fire side and burner maintenance; and boiler room housekeeping.
