A source of air (oxygen) is necessary in order for combustion to take place. Whatever combustion air is consumed by the fire must be replaced. Air is replaced via air leakage around win- dows and under doors. In homes that have tightly sealed doors and windows, an outside air source is needed. An optional Out- side Air system is available.
