OUTSIDE AIR
It is mandatory
to install an outside air connection to the LE LAVAL fireplace. The following
components are required and are included with the fireplace:
-
Outside air kit
-
4" adapter for fireplace connection
The outside air assembly must be installed according to the following requirements :
A)
Duct length should be kept to a minimum. The maximum length of a 4" interior diameter
(100 mm) insulated flexible duct is 20 ft. (6.1 m). The duct can be extended to a
maximum of 40 ft. (12 m) using a 6" interior diameter (150 mm) insulated flexible duct
(See note below).
B)
The air intake register must not be installed more than 10 ft. (3050 mm) 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, basement or garage.
D)
The air intake 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 meters and other vents.
E)
The duct and register may be installed above or below floor level.
Make a 4 ¼" (110 mm) hole in the outside wall of the house at the chosen location. From
outside, place the outside air register in the hole (open side down) and fasten the register to the
wall with screws as shown (see figure 24). Slip the pipe into the insulated sleeve. Place the
insulated pipe over the register tube and over the fireplace‟s outside air connector (see figure 25).
At each end, carefully pull back the insulation and plastic cover exposing the flexible pipe.
Using the aluminium tape provided, wrap the tape around the joint between the flexible pipe and
the air inlets. Carefully push the insulation and plastic cover back over the pipe. Using
aluminium tape, fasten the plastic cover in place.
NOTE
: We recommend not to exceed 20 feet of 4” flexible pipe. If you require a longer length
we recommend that you use a 5” diameter flexible pipe for the complete run up to 30 feet and a
6” diameter pipe for a run of up to 40 feet.
