Framing And Finishing - Masport PG121-NG Owners & Installation Manual

INSTALLATION
1) For ease of installation, frame your fireplace after it is positioned and
the flue system is installed. Remember to install the top standoffs.
See page 11 for assembly. Use 2x4's and frame to local building
codes.
CAUTION: Verify your fireplace dimensions, framing methods
and finished wall facing details before framing. Determine the
total thickness of facing material - drywall plus ceramic tiles,
slate, etc. Allow the finish surface to be flush with the front or
side of the unit. Total facing thickness can vary from 1/2"
(13mm) to 1-1/4" (32mm) thick.
2) When locating your appliance on an exterior wall or in a chase, apply
a vapour barrier and drywall, as per local building codes. DO NOT
INSULATE THE FIREPLACE ITSELF.
CAUTION: The unit does not have to be completely enclosed in
a chase. The clearance on top of the unit is 0" to the standoffs
so combustible building materials can be laid directly on top of
the standoffs. You must maintain
combustible materials for both rigid and flex, see Flue Clear-
ances, page 9.
