5.7.2 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 /
de
fl
ectors) 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
fi
replace, may be removed provided they are available to be re-
installed in event the heater is removed.
A warning label must be attached to the back wall of the
fi
re-
place stating that “This heater has been altered to accommo-
date a
fi
replace insert and must be re-inspected by a quali
fi
ed
person prior to re-use as a factory built
fi
replace”.
A non-combustible hearth must cover the
fl
ooring underneath,
as well as extend a minimum of six inches in front and to both
sides of the heater.
Clean all ashes out of the inside of the heater. Make sure that
the chimney and
fi
replace are free of cracks, loose mortar, creo-
sote deposits, blockage or other signs of deterioration.
If necessary, have any repair work done by a quali
fi
ed profes-
sional before installing the heater.
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 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 two
inches 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 heater.
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 instal-
lation 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.
H.
Pull the excess length of liner out through the top of the chimney. Trim the excess liner, install the cap
and cap the chimney.
