P36 - P36D Gas Fireplace

Framing and Finishing

1)Determine the total thickness of facing material (e.g. drywall plus ceramic tiles) 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.

2)Frame in the enclosure for the unit with framing material.

Note: Header for the P36 must be installed vertically to maintain clearances to combustible materials. Non combustible header may be installed horizontally.

3)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 fireplace itself.)

4)The top of the unit must not be closer than 32” (813mm) to the ceiling.

5)Combustible material may be brought up to the top and sides of the unit and be covered with ceramic tiles, bricks, rock or other suitable combustible fi nishing materials.

If using the Barcelona Surround, Kensington, Balmoral, or Tripoli Screen Door please note that framing and facing must be non combustible (12” on top and 6” on both sides) and that the Barcelona is only approved for installation with a single sidewall.

Note: 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 proper clearances from the vent to combustible materials (See Below).

6)Use metal studs for framing where the minimum clearance from the vent to combustible material cannot be maintained.

Vent Clearances	Clearance Dimension
Horizontal - Top	2” (51mm)
Horizontal - Side	1-1/2” (38mm)
Horizontal - Bottom	1-1/2” (38mm)
Vertical (Flex or Rigid)	1-1/4” (32mm)

WARNING

Failure to maintain required clearances is a major cause of chimney related fires. Installation of this fireplace must comply with these clearances.

Combustible Mantels

Because of the extreme heat this fireplace emits, the mantel clearances are critical. Combustible mantel clearances from top of the louvers are shown in the diagram below. Mantel may be installed anywhere in the shaded area or higher.

Note: Ensure the paint that is used on the mantel and the facing is “heat resistant” or the paint may discolour.
