Framing and Finishing
1. Determine the total thickness of facing
material (e.g. drywall plus ceramic tiles) to
allow the finished surface to be flush with
the front of the unit. Total facing thickness
can vary from 1/2" (13mm) to 3-3/8" (86mm)
thick.
2. Frame in the enclosure for the unit with
framing material. The framed opening is
45-1/4" high(46-3/8" - if using base
standoffs) x 46-1/2" wide x 21-1/2" deep
(1149mm high x 1181mm wide x 546mm
deep).
3. For 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.)
Unit Base Standoffs
To accommodate varying thicknesses and finishes
of hearth materials, we have increased the overall
height of the appliance by a further 1 1/8”. This
increase is added with the inclusion of two stand-
offs at the bottom of the unit, below the outer box,
taking the overall height of the framing dimensions
from 45-1/4” up to 46-3/8”.
In the event that you should choose to use thinner
materials to finish the hearth, you can omit the
standoffs provided for raising the unit. However, we
recommend that you leave the framing dimensions
as they are in the manual and alter only the facing
requirement by reducing it by the same distance
that you have lowered the unit.
Insert the 2 unit base standoffs underneath
the unit as shown in the diagram below. Space
the standoffs centrally, approximately 2 or 2-1/2
feet apart. Ensure that the unit is not unstable.
Install Top Standoffs & Side Nailing Strips
before unit is slipped into position. See the
"Unit Assembly Prior to Installation" section
for assembly details.

Note: After unit is framed in, steel studs can
be used inside of the wood framing to attach
the noncombustible material. An optional steel
stud framing kit is available for this purpose–see
manual for details. If choosing not to purchase
this kit, steel studs can be used in place–to
attach the non combustible material. Use the
optional steel stud kit instructions as a guide.
