OPTIONAL FRESH AIR INTAKE INSTALLATION INSTRUCTIONS

Optional Fresh Air Intake Kit (Figure 1)
Installation of our 6" fresh air intake kit is simple and easy to complete. This system MUST BE installed before the fireplace is enclosed with finishing material. The air will be drawn into the cooling layer of the fireplace and be completely separated from the combustion casing of the direct vent fireplace. Cooler outside air will mix with room air, circulating around the firebox to reduce the heat output and bring heated, fresh air into the house to provide a more positive balance.
