F. Outside Air Kit Installation
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
windows and under doors. In homes that have tightly sealed
doors and windows, an outside air source is needed. An
optional Outside Air Kit is available.

• Drills and saws necessary for cutting holes through
the wall or flooring in your home.
