4.6.7 INSTALLATION INTO A mASONRY hEATER

Prior to installation:
When installing 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 accommo-
date 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 profes-
sional 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 stove. Refer to manufacturer's installation instructions
and see the "GENERAL VENTING" section.
F. Run a liner down the chimney and connect to tee.
G. Position the heater 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.
