OUTSIDE AIR
It is mandatory to install an outside air connec-
tion to the Cambria™ fireplace. The following
components are required and are included with
the fireplace:
• Outside air kit
• 4” adapter for fi
replace connection
The outside air assembly must be installed ac-
cording to the following requirements:
A) Duct length should be kept to a minimum.
The maximum length of a 4” interior diam-
eter (100 mm) insulated flexible duct is 20
feet (6.1 m). The duct can be extended to a
maximum of 40 feet (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 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 26).
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 27
). At each end, carefully pull back the
insulation and plastic cover exposing the flex-
ible 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
(6.1 meters) 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.
