Combustion air can be supplied to the stove in one of two ways. Consult your local building code or CAN/
CSA-B365, or NFPA 211
1. Direct outside air supply - (Necessary for mobile home installation, optional for residential installation.)
•
To draw outside air through the floor; Attach the outside air adapter to the underside of the stove. Mark
then cut or drill a 3"(76mm) diameter or larger hole in the floor under the adapter. This hole must get its
air from a ventilated crawl space or be extended with duct to the outdoors (Figure 6 on page 15. or
Figure 7 on page 16
**If you are getting the intake air from a well ventilated crawl space, Connect the adapter to 3"(76mm)
flexible or rigid metal venting passing thru the hole using into the ventilated space. Cover the inlet of the
pipe with a 20GA wire mesh minimum rodent screen, and clamp in place.
**If you are extending the pipe thru to the outside, Install an approved 3"(76mm) inlet vent cap into the
closest outside wall. Connect the stove's adapter to the Inlet vent through the hole using 3"(76mm) flex-
ible and/or rigid metal venting.
•
To draw air from behind the stove. Cut or drill a corresponding hole in the closest exterior wall. Install an
approved 3"(76mm) inlet vent cap. Attach the outside air adapter to the underside of the stove. Connect
the adapter to the inlet vent cap using 3"(76mm) flexible and/or rigid metal venting. Provide water pro-
tection as required.
2. Room air supply - Remove the knockout or cover plate from the bottom of the Air box enclosure. The
stove will now draw its air from the room through this opening and into the firebox intake
Note:
The use of outside combustion air for installation requires the unit to be secured to the structure to prevent
dislodging of the air duct ("Securing Bracket Installation:" on page 13).
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.
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 in an air tight home.
