Outside Air Floor Duct (OAFD-S)

Outside air can be delivered for combustion air by utilizing this floor penetration duct.

(Duct penetration measures 5 ¼” square)

Blower Kit (BK-100)

A Blower Kit (includes rheostat for variable speed con- trol) is available for increased heat circulation.

Back Cover Plate (BCP-19)

See illustration above. When using outside combustion air, the back cover plate is required to seal off the primary combustion air intake, so that it can no longer draw air from within the room.

Variable Speed Control, Dial-A-Temp

Stove-Stat Kit (SSK)

To automate the blower system an additional Stove-Stat kit can be purchased. The Stove-Stat is a heat sensor switch that will automatically turn on the blower when the stove is hot and automatically turn it off when the stove is cool.
