FACTORY BUILT (METAL) HEATER INSTALLATION
Prior to installation: Stand-offs may be removed to fit
the insert into the fireplace.
When installing the insert into a masonry fireplace, do
not remove any brincks or masonry. Do not weaken the
structure, or reduce the protection for combustible
materials to less then that required by the National
Building Code.
Bolted or screwed together pieces (smoke shelf /
deflectors) may be removed, but must be able to be re-
installed if the heater was removed.
External trim pieces, which do not affect the operation of
the fireplace, may be removed, provided they are able to
be re-installed in the event the heater is removed.
A warning label must be attached to the back wall of the
fireplace stating that "This fireplace has been altered to
accomodate a fireplace insert and must be re-inspected
by a qualified person prior to re-use as a factory built
fireplace".
A non-combustible hearth must cover the flooring
underneath, as well as extend a minimum of 6" in front
and to both sides of the stove.
Clean all ashes out of the inside of the fireplace.
Make sure that the chimney and fireplace are free of
cracks, loose mortar, creosote deposits, blockage, or
other signs of deterioration. If necessary, have any repair
work done by a qualified professional before installing
the heater.
A. Remove the fireplace damper or fasten it permanently open.
B. Measure the throat of the fireplace and mark this shape on
a piece of 24 gauge sheet metal (flue cover). Cut a hole, sized
for the pellet liner, to lie directly below the fireplace flue opening. Allow 2" of material for a flange on
all sides and cut to these measurements. Bend down the flanges. If you have never done this
before, it might be a good idea to make a cardboard pattern and test it first. Fasten this flue cover in
position as high as possible with two masonry screws per side through the flanges into the fireplace.
C. If you plan on connecting outside air it is recommended to do so at this time.
D. Install floor protection if necessary.
E. Connect the pellet vent with a Clean-Out-Tee to the back of the insert.
F. Run a liner down the chimney and connect to the Tee.
G. Position the insert in it's final location.
H. Pull the excess length of the liner out through the top of the chimney. Trim the excess liner,
install the cap the chimney.
