All-Fuel Chimney - 5" to 8" Installation Instructions
Hart & Cooley, Inc.
Roof Guy Installation
If the chimney extends 5 feet or more above the roof deck,
roof guys are required. The roof guy kit, containing
telescopic legs and a draw band, is suitable for this
application. The draw band must be clamped around the
chimney and the two legs lagged to the roof into the rafters
and not just the roof sheathing. Position the band
approximately two-thirds of the way up the chimney height.
The preferred location for the band is next to a chimney
joint, immediately above or below a locking band.
The two telescopic legs should form an angle of about 60°
to give support to the chimney in all directions. Keep
bottom ends equal distance from the chimney and,
if possible, at the same elevation on the high side of the
sloped roof. Seal the roof with a suitable nonhardening,
waterproof caulking. After the legs are attached to the
chimney and bands, tighten the clamps on the legs to fix
the position of the telescoping legs. See Figure 27.
Maintenance and Cleaning of Chimney
Creosote and Soot - Formation and Need for Removal
The need for chimney maintenance depends on the kind
of appliance and how it is operated. Gas and oil-burning
appliances need very little chimney maintenance, but
wood-burning appliances may need a great deal more.
How you burn wood in your stove or fireplace directly affects
the formation of creosote. Use more dry kindling and paper
first to warm up the chimney to a temperature between
350°F to 500°F. Burn hot, bright fires, and fire each load
hot. It is important to load your appliance properly and to
avoid smoldering fires. Fast, effective start-ups are
important, as is the moisture content of the wood being
burned. If your wood is not completely seasoned, split your
wood into smaller pieces instead of larger ones. Ideally, the
moisture content of your firewood should be between 18%
to 22%. A good investment in assisting you in monitoring
your system is a surface thermometer for single-wall
stovepipe or a probe thermometer for double-wall stovepipe.
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 a
relatively cool chimney flue of a slow-burning fire. As a
result, creosote residue accumulates on the flue lining.
When ignited, this creosote creates a chimney fire with
extremely high temperatures.
With a new installation, the chimney should be inspected
frequently (every two weeks) to determine the rate of
creosote formation. When familiar with the appliance and
chimney characteristics, the chimney should be inspected at
least once every two months during the heating season to
determine if a creosote or soot build-up has occurred. Check
spark arrestor screens at least every two to four weeks.
If creosote or soot has accumulated, it should be removed
to reduce the risk of a chimney fire. Depending on the
rate of build-up (as little as
1
/
16
") and as you learn what is
going on in the chimney, you can adjust your cleaning
schedule accordingly. Every chimney flue and flue pipe
should be inspected annually and cleaned as often as
necessary to keep the chimney and flue pipe free from
dangerous accumulation of combustible deposits.
Contact a professional certified chimney sweep for
chimney cleaning services and advice if you have any
doubts about your ability to clean your chimney system or
if the task is too large. To visually inspect the chimney,
remove the rain cap by simply using the twist-lock feature.
This will permit the insertion of a flashlight for inspection
and a properly sized plastic chimney-cleaning brush.
A metal brush may scratch the liner and lead to premature
corrosion. The tee cap (if so equipped) can be removed
by turning counter-clockwise to clean from the bottom.
Be sure to replace the tee cap and rain cap when you are
finished cleaning the chimney.
To reduce corrosion in the chimney where coal is burned, the
system must be thoroughly cleaned within 48 hours of shutting
down the appliance for the season, and all soot should be
removed from the chimney system. Ensure that only low
sulphur content coal (1% or less), such as anthracite, is burned.
