A. 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.

4 inch flex aluminum pipe, or if using alternate material,
then it shall be made from durable, non-combustible,
heat resistant material up to 350oF. Cut the pipe to the
required length for your installation.
