OUTSIDE COMBUSTION AIR
1.
Under certain conditions it is recommended that the stove be connected to an outside source
of combustion air to improve performance. Flexible metal hose, or rigid metal pipe,
(conduit), must be connected around (NOT INSIDE) the combustion air inlet tube. Be careful
not to pinch or bend the outside air pipe with too small a radius which may be terminated
flush with the outside wall but should be protected from wind and weather by a hood. Note:
The outside air pipe must terminate above the maximum snow line.
Optional Outside Air Kit
100354 is available to connect to the intake damper.

2.
Outside air may be drawn from a semi-enclosed attic or crawl space or any semi-enclosed
space. Take care not to draw cold air past water pipes that may freeze.
3.
Increase the outside air pipe diameter to 3” for runs over ten (10) feet and elevation over
4,000 feet. Note: Long runs should be avoided.
4.
Terminate the outside air pipe below the exhaust vent outlet.
5.
An open mesh screen should be placed over the outside air pipe opening to prevent birds or
rodents from nesting in the opening. Use an elbow or shield to prevent prevailing winds from
blowing directly into the outside air intake pipe. NOTE: Mesh screen should be no smaller
than one-fourth inch (1/4”) by one-fourth inch (1/4”).
WARNING: OUTSIDE COMBUSTION AIR IS REQUIRED FOR ALL MOBILE HOME INSTALLATIONS!
