PRIOR TO INSTALLATION
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, cresote deposits, blockage or other signs of deterioration. If necessary, have any repair work done by a qualifi ed professional before installing the insert.
Do not remove bricks or mortar from the fi replace.
INSTALLATIONINTOAMASONRYFIREPLACE
1.Remove the fi replace damper or fasten it permanently open.
2.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 mea- surements. 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 first. fasten this flue cover in position as high as possible with two masonry screws per side through the fl anges into the fi replace.
3.If you plan on connecting outside air it is recommended to do so at this time.
4.Connect the pellet vent with a clean out tee to the back of the stove. Refer to manufacturer's installation instructions and the "General Venting Section".
5.Run a liner down the chimney and connect to tee.
6.Position the stove in it's fi nal location.
7.Pull the excess length of liner out through the top of the chim- ney. Trim the excess liner, install the cap and cap the chimney.
