To make installation easier, put the appliance in place and install the vent system before framing the
fireplace. Remember to install the required clearance post on top.
If you install your fireplace on an outside wall or in an alcove, use a firewall and drywall in compliance
with local building codes.
3.1.4. TOP CLEARANCE
Top clearance post are not installed when
you receive your fireplace. They must be
mounted before installing the unit. Eight
machine screws are already placed on top
of the fireplace where clearance post will
go (2 screws per spacer). Please see the
following illustrations.
3.1.5. FACING MATERIALS
Only non-combustible materials (brick, slate tile, steel or other non-combustible materials allowed by local
standards) can be used to cover
the appliance’s non-removable/fixed surfaces.
WARNING
Before framing your fireplace, check dimensions, framing methods and finished wall facing
details. Determine the total thickness of the finishing material
– drywall, ceramic, tile, slate, etc.
Make sure the finished surface will be flush with the front or side of the unit.

CAUTION
Never obstruct the air duct inlet or outlet. This could pose a risk of overheating, which could lead
to a fire.
CAUTION
Remote wiring (wall switch) must be before the facing materials to avoid costly reconstruction.
The appliance must not be completely enclosed in an alcove. Clearance above the top of the
fireplace is 0 in. from the top clearance post. This means that combustible building materials can
rest directly on top of the upper mounts.
You must leave a 3 in. clearance between the first 8 ft. of vent and combustible materials
(unless protected by a firewall). The rest of the vent requires a clearance of 1 in.
