OUTSIDE AIR INLET
During operation, the fireplace requires fresh air for combustion and draws air out of the house. It
may starve other fuel burning appliances such as gas or oil furnaces. As well, exhaust fans may
compete for air, causing negative pressure in the house, resulting in smoke entering the house from
the fireplace. This situation is aggravated in an airtight house. To overcome this problem, we
strongly recommend that you
install an outside air assembly.
Check with local authorities having
jurisdiction in your area, it may be mandatory.
2.5.1
Installation of external air intake
The external air intake kit must be installed according to the following instructions.
1)
The maximum length of the duct must be 20 feet. The length of the duct should be as short
as possible, but should have a ‘’S’’ or loop to prevent air from entering too directly.
2)
The air register should not be installed at more than 7 feet above the base of the fireplace.
3)
Fresh air must come from the exterior of the house.
4)
The air intake should not be fed by the basement, the attic or the garage air.
5)
The external register should not be able to intake the release of car, gas or other air outlets.
6)
The register, if possible, must be placed in a way that it cannot be blocked by snow or
exposed to extreme winds.
7)
The register and the duct can be installed either under or over the floor. (See the following
page).
Make an opening of 102 mm (
4 ¼’’) in the exterior wall of the house at the chosen location. From
outside, install the exterior air intake in the opening (shutters opened downwards).
