6. REPLACEMENT PARTS
Your HOTBLAST furnace is designed to burn clean and require little maintenance. It’s recommended to conduct a
visual inspection at least once a month to uncover any damage on the unit. Make necessary repairs as soon as
possible with genuine Hotblast replacement parts.
DOOR GLASS
• Inspect the glass regularly to detect any breakage or failure. If you find any defect, stop the furnace
immediately. Never operate a furnace with a broken glass.
• If you have to change your door glass, you must use Pyroceram 3/16”(5mm) thick glass available at your
HOTBLAST authorized dealer.
• To replace the glass, remove screws that hold the glass retainers in place. Remove these retainers and
replace the glass. The glass gasket should be replaced at the same time. To put back in place, follow the
same procedure backwards.
• Do not use an abrasive cleanser. Special cleansers for wood stoves glass are available in any good
hardware store.
• Clean glass ONLY when the unit has cooled down.
GASKET
We recommend to replace the gasket that seals the door once a year, in order to maintain a good control of the
combustion for maximum efficiency and security. To replace your door gasket, remove the old gasket and glue.
Clean the surface thoroughly, apply glue sold for that particular use, and put the new gasket onto the door. Wait for
at least 2 hours before lighting your furnace.
