24. Maintaining Tight Seals
It is very important to maintain tight seals on the doors, heat exchanger cover plate and the firebox bypass chimney damper. Poor
seals can result in smoke and gases leaking out of the boiler and lead to uncontrolled burning which may cause the boiler to overheat.
The fiberglass rope used to seal both doors and the heat exchanger cover should be inspected regularly and treated with graphite or
some other lubricant like motor oil or WD-40 as needed, to keep them flexible. Over time the rope seals on the doors can become
flattened through normal use. When this occurs, the door hinges can be adjusted to compensate for the new shape of the sealing rope.
To do that, remove the door, loosen the cap, turn the hinge 360°, and tighten the blocking nut to block the hinge retaining screw. The
upper and lower hinges should be adjusted at the same time.
25. Off Season Preparation
Acids produced during the wood burning process can form when exposed to moisture inside the firebox, heat exchanger tubes and
secondary combustion chamber. It is important that the boiler be properly prepared for the off season (summer) idle period. T he upper
and lower combustion chambers, heat exchanger tubes and chimney bypass damper should all be thoroughly cleaned of creosote, soot
and ash. After the boiler is cleaned, both doors should be left open to avoid condensation.
WARNING!
Chimney inspection and maintenance is a critical part of any wood burning maintenance schedule.
Inspect it at least once annually - preferably at the
start of heating season. Clean as needed.
