9.8 CrEOSOTE FOrmATION ANd rEmOvAL
When wood is burned slowly, it produces tar and other organic vapors
which combine with expelled moisture to form creosote. These vapors
condense in the relatively cooler chimney flue of a slow burning fire and
when ignited, make an extremely hot fire. Check your chimney from
creosote and soot build-up daily, until a safe frequency for cleaning is
established. The chimney connector and chimney should be inspected
at least twice monthly during the heating season to determine if a
creosote build up has occurred. be aware that the hotter the fire, the
less creosote is deposited, and weekly cleanings might be necessary in
mild weather, even though substantially longer period without cleaning
may be sufficient in colder months.
also note that small intense fires are preferable to large smoldering
ones to reduce the amount of creosote deposited.
if accumulation is excessive, clean the chimney. you may want to
call a professional chimney sweep to clean it. both the chimney and
the appliance have to be cleaned at least once a year or as often as
necessary.
CREOSOTE IN EXCHANGER
TUBES
The three heat exchanger pipes should be inspected regularly during the burning season. easy access is provided
(without the use of tools); simply unscrew the common knob on the exchanger access door, figure 1.
before cleaning the three exchanger pipes move the upper baffles of the combustion chamber forward (see figure
2), and fully open the bypass damper.
using the 5” (127 mm) Poly Sweep brush and rod provided clean the three heat exchanger pipes. noTe: The 5”
(127 mm) brush will be difficult to remove from the 2 smaller exchanger pipes for the first couple uses. it is recom-
mended for the first use to lightly heat the plastic bristles with a heat gun until they are more pliable. Please note that
excessive heat can damage the brush. after a couple uses the brush will loosen up and require less force.
The accumulated creosote will fall into the combus-
tion chamber and can then be removed. ensure
the upper baffles are free of creosote and then
push them back into their original position. remove
any excess creosote from the exchanger cleanout
compartment and close the exchanger access door.
regular cleaning will ensure the greatest operating
efficiency.
