Prefabricated Fireplace Installation
A factory-built fireplace will require modification prior
to installation of the insert.
Modification
1. Remove any fuel grate and other components if
attached. On most models, the firegrate is attached
to the unit with brackets which can be cut or pried off.
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 firescreen or door assembly. This is
usually accomplished with removal of a support rod
on the inside of the fireplace frame.
4. Remove the metal ashlip, if appropriate, to allow the
insert to sit flat within the fireplace. Be sure to
reinstall any screws removed.
IMPORTANT:
BEFORE STARTING THIS INSTALLATION, MAKE SURE THAT A
GAS LINE CAN BE INSTALLED OR IS INSTALLED TO THE FIRE-
BOX. THIS SHOULD ONLY BE DONE BY A QUALIFIED OR
LICENSED PLUMBER OR GAS FITTER.
Installation
Follow the same installation procedural steps detailed
on the preceding page for masonry fireplaces.
