3. Feed the power supply wires through the strain relief in the cover plate
and into the unit junction box.
4. Connect the black power supply wire to the power outlet red and black
pigtails together. Connect the white power supply wire to the outlet

OUTSIDE AIR KIT

It is mandatory to install an outside air connection to the wood burning
fireplace. The following components are required and are included with
the fireplace:
• Outside air kit (includes 4 inch flex that goes up to ten (10) feet long)
• 4" Adaptor for fireplace connection
The outside air assembly must be installed according to the following
requirements:
Outside Air Installation
The outside air assembly may 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 twenty (20)
feet (6.1 m). (See note below).
B) The air intake register must not be installed more than ten (10) feet
(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 4-1/4" (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 19A). 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 19B). 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.
