5.1.5 Cleaning and painting the furnace
Do not attempt to clean or paint the furnace when the unit is hot. Painted surfaces
can be wiped down with a damp cloth. Plated or enameled surfaces may be scratched by
abrasive cleaners. To maintain the finish at its original brilliance, use only a damp soft cloth
to clean plated or enameled surfaces.
If the paint becomes scratched or damaged, you can give your wood furnace a brand new
look by repainting it with heat-resistant or enamel finish paint. Before painting, roughen the
surface with fine sand paper, wipe it down to remove dust, and apply two thin coats of
paint. For best results, use the same paint that was originally used on the furnace, which is
available in spray cans. See your dealer for details.
5.1.6 Heat exchangers care
Heat exchangers must be cleaned thoroughly at the end of every heating season. During
summer, the air in basements is damper and with minimal air circulation within the furnace,
it can mix with creosote and/or sooth deposits in the exchangers to form an acid that could
accelerate the corrosion process and induce premature decay of the steel. Corrosion
damages are not covered under warranty.
Smoke pipe and exchangers must be inspected regularly during the heating season.
Access to the exchangers is easy and does not require tools;
1. Unscrew the wing nut (B) and remove the washer (C) on the exchanger access door.
