Framing and Finishing
1) Frame the enclosure for the unit with framing material. Use the
determined total thickness of facing material (e.g. drywall plus
ceramic tiles) to adjust the framing depth to allow the fi nished
surface to be fl ush with the front of the unit. Total facing thickness
can vary from 1/2” (13mm) to 1-1/4” (32mm) thick.
Note: Header for the P40 must be non combustible.
2) For exterior walls, insulate the enclosure to the same degree as
the rest of the house, apply vapor barrier and drywall, as per local
installation codes. (Do not insulate the fi replace itself.)
3) Ensure that all of the clearances listed below are met. Combustible
material may be brought up to the sides of the unit and be covered
with ceramic tiles, bricks, rock or other suitable combustible
fi nishing materials. Non-combustible facing is required above
the unit. (See Dimension “N” on page 41)
Note: You must maintain proper clearances from the vent to
combustible materials (See Below).
4) Use metal studs for framing where the minimum clearance from
the vent to combustible material cannot be maintained.

chimney related fi res. Installation of this fi replace must comply
