P33 Gas Fireplace
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).

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

WARNING
Failure to maintain required clearances is a major cause of chimney related fires.
Installation of this fireplace must comply with these clearances
Please note: Due to ongoing product development, product appearance and specifications
are subject to change without notice.
WARNING
Fire hazard is an extreme risk
if these clearances (air space) to combustible materials are not
adhered to. It is of greatest importance that this fireplace and vent
system be installed only in accordance with these instructions.
Caution Requirements
The top, back and sides of the fireplace are defined by
standoffs. The metal ends of the standoff may NOT be
recessed into combustible construction.

When installing Cabinet Mantels: the wall thimble must be secured
first and venting must be attached to unit before sliding into final
position.
This venting system, in combination with the P33 Direct Vent Gas
Fireplace, have been tested and listed as a direct vent heater system by
Warnock Hersey. The location of the termination cap must conform to the
requirements in the Vent Terminal Locations diagram, see manual.
FPI Direct Vent (Flex) System Termination Kits include all the parts
needed to install the P33 using a flexible vent.
