Important:
If the Contemporary Faceplate is used on the P33-NG4/P33-
LP4 Gas Fireplace, the burner orifice (Both NG/LP supplied in
package) must be replaced and an overlay decal (also supplied
with kit) must be affixed to the current serial number decal
supplied with unit.
Note: Also see framing dimensions for this optional front if
installed on the P33-4 unit.
Note: Unit must be raised up by 1' to allow for faceplate
installation.

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 1-¼”
(32mm) thick.
2) Frame in the enclosure for the unit with framing material.
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 30” (762mm) 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 finishing materials.
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.

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.
