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)
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.
Blower Kit (BK-100)
A Blower Kit (includes rheostat for variable speed con-
trol) is available for increased heat circulation.
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.
