Framing and Finishing Inset Installations
1. Frame in the enclosure for the unit with framing material
Note: When constructing the framed opening ensure there is access to install
the gas lines,electrical. Also the wiring harness must be wall mounted using
the receptacle provided with the appliance. The wiring harness will be located
on the right hand side of the appliance if facing the unit from the front. This
must be done prior to any finishing.
2. F or exterior walls, insulate the enclosure to the same degree as the rest of
the house, apply vapour barrier and drywall, as per local installation codes.
(Do not insulate the fireplace itself.)
Note that in all applications while there is a zero clearance to combustibles
to the unit, all clearances to combustibles from the venting inside the chase
still applies. Please see venting clearances in the specific product manual.
WARNING: Failure to insulate and add vapor barriers to the inside of the
exterior wall will result in operational and performance problems including, but
not limited to: excessive condensation on glass doors, poor flame package,
carbon, blue flames etc. These are not product related issues.
3. IMPORTANT: Exterior wall/Alcove enclosure: When installing into an
exterior cavity or alcove enclosure (ceiling, back and sides), regardless of
where appliance is placed within the home, requires the use of either drywall
or other means such as plywood, wood studs, etc. to prevent heat from
escaping anywhere above /though the enclosure other than the required
grill/ventilation openings.
• Internal chase: When installing as an internal chase framing installation,
regardless of where appliance is placed within the home, requires the use
of either drywall or other means such as plywood, on the rear wall of the
chase to eliminate heat escaping into the rear wall cavity. If the chase is
extended to the ceiling, the ceiling will also need to be finished in a manner
to prevent heat escaping into floor joist/attic space. One of the following
methods must be used to prevent the heat from escaping :
a. If choosing drywall, ensure that the drywall is butt up tight with no gaps.
b. Plywood, wood studs, etc. installed tightly with no gaps.
• As this appliance has been designed with all hot air escaping through
the chase enclosure ventilation/grill openings only, if hot air is trapped as
a result of the hot air escaping through joints, crevasses, open studs, or
other openings within the enclosure above, this will change the clearances
within the enclosure causing the enclosure to overheat. It is vital that all the
hot air from within the enclosure exits through the ventilation openings only.
Ensure that the ventilation openings are made as such to prevent debris,
objects from falling into the enclosure.
4. C ombustible material (drywall,wood,wood panels, etc.) may be brought up
to the appliance (top,bottom and sides)
5. E nsure that the material being used does not encroach anywhere in the
area of the glass. This would cause dangerous operating conditions.
6. T his appliance comes with a 1/2" lip at top and bottom to hide the ends of
the drywall. The 1/2" side and bottom lip supplied with the appliance can
alternatively be removed (see Diagram 1) and replaced with J Style Trim
or Metal Corner Bead purchased at your local hardware store to cover cut/
exposed edges of the combustible facing material or any other finishing
materials being used. 6 screws secure the bottom lip — see Diagram 1.
These will be hidden so the outer panels will need to be removed to access
the screws. See outer panel removal in this manual.
7. T his appliance can also be recessed (using combustible materials) with
a hearth in front of the appliance. This can also extend to the top. See
manual for details.
Note : Combustible material may extend a minimum of 1/2" and to a maximum
of 5-1/8" (130mm) from the front top (with larger glass). See mantle clearance
chart for details. The base and side (with smaller glass) have no limit regarding
how far the combustible material may extend from the appliance. Ensure that
no material encroaches anywhere in the area of the glass as it is defined by
the finishing lip surrounding the appliance.
Drywall Lip - Bottom and Sides (Optional)
If desired the finishing lip on both sides and bottom may be removed. Re-
move the 2 screws on each side to remove the side drywall lip and loosen
6 screws (in locations shown below) from behind front face of unit with an
offset screwdriver and lift off drywall trim to remove. The top drywall lip can-
not be removed from the appliance. Also see finishing details on next page.
