4.7 INSERT VENTING INSTALLATION EXAMPLES
4.7.1 TYPICAL EXISTING MASONRY INSTALLATION
!
WARNING
Prior to installation:
When installing the insert into a masonry fi replace, do not
remove any bricks 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 / 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 fi replace 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 fi replace”.
Non-combustible fl oor protection must cover the fl ooring
underneath, as well as extend a minimum of six inches 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 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 fi replace.
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 th
“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.
DO NOT REMOVE BRICKS OR MORTAR FROM THE FIREPLACE.
