6.0 INSERT INSTALLATION

6.1

mASONRY 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 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 / 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 available to be re-installed in 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 accommodate 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 six inches in front and to both sides of the heater.
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 two inches 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. 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 final 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.
