4.7.2 FACTORY BUILT FIREPLACE
Prior to installation:
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 /
defl ectors) may be removed, but must be able to be re-installed
if the appliance is removed.
External trim pieces, which do not affect the operation of the
fi replace, may be removed provided they are available to be re-
installed in event the appliance is removed.
A warning label must be attached to the back wall of the
fi replace stating that “This heater has been altered to
accommodate a fi replace insert and must be re-inspected by a
qualifi ed person prior to re-use as a factory built fi replace”.
Non-combustible fl oor protection must cover the fl ooring
underneath, as well as extend a minimum of 6” (152.4mm) in
front and to both sides of the appliance.
Clean all ashes out of the inside of the fi replace. Make sure
that the chimney and fi replace are free of cracks, loose mortar,
creosote deposits, blockage or other signs of deterioration.
If necessary, have any repair work done by a qualifi ed
professional before installing the appliance.
A.
Remove
the
fi replace damper or fasten it permanently
open.
B.
Measure the throat of the fi replace and mark this shape on a piece of 24 (0.511mm) gauge sheet metal
(fl ue cover). Cut a hole sized for the pellet liner to lie directly below the fi replace fl ue opening. Allow 2”
(50.8mm) of material for a fl ange on all sides and cut to these measurements. Bend down the fl anges.
If you have never done this before, it might be a good idea to make a cardboard pattern and test it fi rst.
Fasten this fl ue cover in position as high as possible with two masonry screws per side through the
fl anges into the appliance.
C.
If you plan on connecting outside air it is recommended to do so at this time.
D.
Install
fl oor protection if necessary.
E.
Connect the pellet vent with a clean out tee to the back of the insert. Refer to manufacturer’s
installation instructions to see “REAR TO TOP VENT CONVERSION INSTRUCTIONS” section and the
“GENERAL VENTING” section.
F.
Run a liner down the chimney and connect to tee.
G.
Position the insert in it’s fi nal location.
