2.6 FRESH
AIR
KIT
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 modern airtight houses.
To overcome this problem, we strongly recommend that you
bring fresh air to the
fireplace. Check with local authorities having jurisdiction in your area, it may be
mandatory.
2.6.1 Fresh Air kit Installation
Refer to the following requirements to install a fresh air kit to the fireplace:
A)
Insulated duct length should be sufficient to avoid condensation.
B)
The outside wall termination must not be installed more than 10 ft. (3 m) above the
base of the fireplace.
C)
The fresh air must come from outside the house. The air intake must not draw air
from the attic, from the basement, or from a garage.
D)
The outside wall termination should be installed where it is not likely to be blocked
by snow or exposed to extreme wind and away from automobile exhaust fumes, gas
meter and other vents.
E)
The outside termination may be installed above or below floor level.
F)
If more fresh air is needed (airtight house or conduit exceeding 10 ft or 3 m), two
intakes may be installed, providing twice the quantity of incoming fresh air; you may
also increase both conduits to 4 inches, with the use of a 3 to 4 inch adaptor, again
increasing substantially the quantity of incoming fresh air.
Your fireplace contains the following components:
a.
One (1) 3" adaptor;
b.
One (1) air inlet block-off plate;
c.
Six (6) screws;
d.
One (1) 3” to 4” adaptor
The following components are not included:
e.
A 3” insulated flexible conduit
f.
The outside air inlet cap
g.
The 2 adjustable straps
To complete the fresh air installation, you will need a 3" insulated flexible pipe. Use the
length required for your installation while respecting the maximum length of 10 ft (3 m).
Make a 3 1/4" (83 mm) hole in the outside wall of the house at the chosen location. From
outside, place the outside air inlet cap in the hole (open side down) and fasten the register to
the wall, with screws as shown (see figure 27). Place the insulated pipe over the register tube
and over the fireplace outside air connector (see figure 28). At each end, carefully pull back
the insulation and plastic cover, exposing the flexible pipe. Attach the flexible pipe using
