Creosote - Formation and Need for Removal
When wood is burned slowly, it produces tar and other organic vapors, which combine with expelled
moisture to form creosote. The creosote vapors condense in the relatively cool chimney ue of a
slow-burning re. As a result, creosote residue accumulates on the ue lining. When ignited, this
creosote makes an extremely hot re. The chimney and chimney connector should be inspected at
least twice monthly during the heating season to determine if a creosote buildup has occured. If creo-
sote has accumulated it should be removed to reduce the risk of a chimney re.
CSA Suggestions:
Establish a routine for the storage of fuel, care of the appliance, and ring techniques.
Check daily for creostoe buildup until experience shows how often cleaning is necessary
Be aware that the hotter the re, the less creosote is deposited, and that weekly cleanings may be
necessary in mild weather, even though monthly cleaning may be enough in the coldest months.
Have a clearly understood plan to handle a chimney re.
Prolonged Power Failure
The boiler air intake ap is closed when fan is not in operation and therefore not designed to operate
in event of power failure. A water circulation loop should be installed that would dissipate at least
10% of the estimated rated heat output of the boiler should be installed and only made inoperative
by a deliberate manual action. The minimum pipe size should be 3/4” diameter with a room ambient
temperature of 65F and a mean water temperature of 180F. The loop should be positioned above the
boiler with feature that promote natural thermal circulation of the water. The recommended piping be
such that excessive pressure will not be developed in any portion of the boiler. See page 12 for pip-
ing diagrams.
Off Season Preparation
Acids produced during the woodburning process can form when exposed to moisture inside the re-
box, heat exchanger tubes and secondary combustion chamber. It is important that the boiler be prop-
erly prepared for the off season (summer) idle period. The 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.
