P35i Fireplace Insert
F. Factory-Built Fireplace Installation
When installing the P35i Insert into a factory built
wood burning fireplace, several things need to be taken
into consideration.
The size of the fireplace opening. Will the unit fit into
the opening? Some of the factory built fireplaces have
metal smoke shields inside the top that can be removed
to gain height. Keep in mind that anything removed
from the factory built fireplace must be attached to the
fireplace with a metal wire.
as listed previously, must also be followed.
The manufactured fireplace may not be altered be-
yond the exceptions listed below. Never remove masonry
bricks or mortar from an existing fireplace.
The following modifications are permissible:
• Removal of the damper or lock in open position
• Removal of smoke shelf or baffle
• Removal of andirons or ember catchers
• Removal of log grate
• Removal of view screen or curtain
• Removal of doors
• External trim pieces, that do not affect the operation
of the fireplace, may be removed providing they can
be stored on or within the fireplace for reassembly if
the insert is removed.
• If the hearth extension is lower than the fireplace
opening, the portion of the insert extending onto the
hearth must be supported.
• Final approval of this type of installation is contingent
upon the authority having jurisdiction.

Floor protection guidelines,
Hearth must be constructed to
the proper height and finished
with a non-combustible
material.
The factory built chimney must be listed per UL 127 (US)
and meet type HT requirements of UL 103 (US). Factory
Built fireplace chimneys tested to UL 127-98 may be, at the
fireplace manufacturers option, tested to the same criteria
as UL 103HT requirements. If the chimney is not listed as
meeting HT requirements, or if the factory built fireplace was
tested prior to 1998, a full height listed chimney liner must
be installed from the appliance flue collar to the chimney top.
Liner must meet high temperature (2100 F) per UL1777 (US).
The liner must be securely attached to both the flue collar
and the chimney cap. To prevent room air passage to the
chimney cavity of the fireplace, seal the damper area around
the chimney liner with fiberglass batting.
