5.2 CHIMNEY MAINTENANCE
One of the most efficient methods is to sweep the chimney is using a hard brush. Brush the chimney downward
so soot and creosote residues will come off the inside surface and fall at the bottom of the chimney where it can be
removed easily.
The chimney must be checked regularly and if creosote has accumulated, it must be removed without delay.
Cleaning on a monthly basis should be sufficient during the coldest months.
Smoke flue inspection
- The smoke flue should be inspected regularly during the heating season.
-
If possible, the smoke flue should be dismantled and cleaned.
- The flue should be inspected to detect any damage.
- If no damage is noticed, put the flue back in place; otherwise, it must be replaced.
- Use only wood as a combustible.
- Seasoned hard wood logs 18” to 22” long are recommended as a combustible.
5.3 MAINTENANCE OF THE BLOWER MOTOR
The two bearings of the motor must be lubricated once a year using non detergent SAE 20 oil.
DO NOT OVERLUBRICATE
FILTERS
The blower must not be operated without the filters. In order to operate a slow combustion heating system
efficiently and safely, you have to ensure regular maintenance. This means that the chimney, the joints and the flue
must be kept in good condition and the air filters must be cleaned or replaced regularly. Use the same size and
same type as the original filters.

5.4 DOOR GASKET MAINTENANCE
It is important to maintain the door gasket in good condition. After a while, the gasket might sag; a door
adjustment may be then required.
