Motor Lubrication
The blowers are permanently lubricated by the manufacturer. Do not
apply oil to any part of the blower. Doing so may cause damage.
Blower Cleaning
Clean the air holes on the motors of both the exhaust and room air blowers
annually. Remove the exhaust blower from the exhaust duct and clean
out the internal fan blades as part of your fall start-up.

Small Area Paint Touch-up
The stove body is painted with a quality high-temperature stove paint.
Use only model TSPK-B Stove Paint, Catalog # 70K99. Do not touch-up
your stove with any other paint.
Using one small piece of 320 grit sand paper and lightly sand the blemish so
that the edges are "feathered" or smooth to the touch between the painted
and bare surfaces. Do not let the sand paper gum up with paint, as this
will cause scratches on the metal surface. If there are any scratches, use
6
600 grit sandpaper instead. Mask off surfaces you do not want painted.
Paint lightly over the bare surface first as this will act as an undercoat.
Then paint over a larger area in smooth even strokes to blend.

The electronic control board is located on the left-hand side of the stove.
It is mounted to the side panel with four nuts. The control board can be

two bolts located on the top and bottom side of the panel. Pull the
edge closest to the door firmly away from the stove and swing side
