Masport P36-3 Gas Inbuilt

INSTALLATION
Note: 40-1/2" (1029mm) is the minimum
height for flex termination.
Note: The unit does not have to be com-
pletely enclosed in a chase. The
clearance on top of the unit is 0" to
the standoffs so combustible
building materials can be laid di-
rectly on top of the standoffs. You
must maintain 1-1/2" (38mm) clear-
ance from the flue to combustible
materials for flex.
5) Use steel studs for framing where the
1-1/2" (38mm) clearance from the flue to
combustible material cannot be maintained,
e.g. front top header.

CLEARANCES

gram below:
FRAMING AND
FINISHING
1) Determine the total thickness of facing ma-
terial (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 1-1/4" (32mm)
thick.
Maximum 38mm projection at 51mm minimum
clearance.
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.)
4) The top of the unit must not be closer than
32" (813mm) to the ceiling.
Install Side Nailing Strips, Top Facing
Support, and Top Standoffs before unit
is slipped into position. See page 9 for
assembly details.
2) Frame in the enclosure for the unit with
framing material. The framed opening is
36-1/4" high x 36-1/4" wide x 12-3/4" deep
(921mm high x 921mm wide x 324mm deep).
