Combustion Air
Intake or combustion air can be supplied to the stove in one of two ways. Consult your local build-
ing codes before proceeding.
1.
Outside air supply - (Necessary for mobile home installation, optional for residential installa-
tion.) To draw outside air through the floor, cut or drill a 102mm diameter hole directly below
the bottom hole of the ash box enclosure(see page 6 Fig. #1a). Connect enclosure to the floor
with a short 102mm diameter pipe.
This hole must get its air from a ventilated crawl space or be extended with duct to the outdoors
(see Figure #4, Page 11). The use of outside combustion air for residential installation requires
the unit to be secured to the structure to prevent dislodging of the air duct.
Not e: When installed in a mobile home, this unit is not designed to be operated with the firing door
open. In addition to the obvious hazard of sparks landing on combustibles, an open fire door
will cause the heater to draw air from the living space and possibly cause suffocation.
2.
Room air supply -There is a 102mm opening in the ash box enclosure. The stove will draw its
air from the room through this opening and into the firebox intake.
Note: The living space around the heater must be well ventilated with good air circulation. Anything
that may cause a negative pressure can cause gases or fumes to be pulled into the living area.
During extremely cold weather, and especially when burning at very slow rates, the upper parts
of the exposed chimney may ice up, partially blocking the flue gases. If blockage occurs, flue
gases may enter living space.
