Prefabricated Fireplace Installation
IMPORTANT:
BEFORE STARTING THIS INSTALLATION, MAKE SURE THAT
A GAS LINE CAN BE INSTALLED OR IS INSTALLED TO THE
FIREBOX. THIS SHOULD ONLY BE DONE BY A QUALIFIED
OR LICENSED PLUMBER OR GAS FITTER.
A factory-built fireplace will require modification prior
to installation of the insert.
Modification
1. Remove any fuel grate and other components at-
tached to the firebox. Do not cut out any sheet metal
parts of the fireplace into which the insert will be
installed.
If the factory-built fireplace has no gas access hole(s)
provided, an access hole of 1 1/2” (37.5 mm) or less
may be drilled through the lower sides or bottom of
the firebox in a proper workmanship-like manner.
This access hole must be sealed with non-combusti-
ble insulation after the gas supply has been installed.
2. Remove the damper assembly. This includes the
damper blade, handle and any linkage. Two 3” liners
must be able to pass through the damper area.
3. Remove any fire screen or door assembly. This is usu-
ally accomplished with removal of a support rod on
the inside of the fireplace frame.
4. Remove the metal ash lip, if appropriate, to allow
the insert to sit flat within the fireplace. Be sure to
reinstall any screws removed.
5. Attach the fireplace conversion notice to the back of
the factory-built fireplace.

NOTICE:
If the intake flex does not extend the full length
of the chimney and connect to the unit and the
termination cap - A METAL BLOCK OFF PLATE MUST
BE CONSTRUCTED AND INSTALLED ABOVE THE UNIT
BELOW THE END OF THE INTAKE DUCT (normally at
the damper area). See figure 9.
To avoid cross venting the insert, label the duct to
be used for the exhaust conduit at both the top and
bottom ends. This ensures that the exhaust duct will
be attached to the correct collar on the insert and on
the chimney termination kit.
CANADA NOTE: Both Intake and Exhaust ducts
must extend the full length of the chimney and be
connected to both the unit and the termination kit.
IMPORTANT NOTICE:
INSTALLATION OF A HIGH-WIND TERMINATION CAP
IS RECOMMENDED FOR ALL IPI APPLIANCES. IF USING
SIMPSON DURA-VENT, AN ADDITIONAL WIND SCREEN
#46DVA-VWG IS ALSO RECOMMENDED.
