draft in your chimney depends on the length of the
chimney, local geography, nearby obstructions and
other factors. Too much draft may cause excessive
temperatures in the appliance. Inadequate
draft may cause backpuffing into the room and
‘plugging’ of the chimney. Inadequate draft will
cause the appliance to leak smoke into the room
through appliance and chimney connector joints.
An uncontrollable burn or excessive temperature
indicates excessive draft.
CHIMNEY
Take into account the chimney’s location to ensure
it is not too close to neighbors or in a valley which
may cause unhealthy or nuisance conditions. Your
wood stove may be hooked up with a 6” factory built
or masonry chimney. If you are using a factory built
chimney, it must comply with UL 103 or CSA-B365
standard; therefore it must be a Type HT (2100°F). It
is extremely important that it be installed according
to the manufacturer’s specifications. If you are using
a masonry chimney, it is important that it be built in
compliance with the specifications of the National
Building Code. It must be lined with fire clay
bricks, metal or clay tiles sealed together with fire
cement. Note: Round flues are the most efficient.
The interior diameter of the chimney flue must be
identical to the stove smoke exhaust. A flue which
is too small may cause draft problems, while a large
flue favours rapid cooling of the gas, and hence the
build-up of creosote and the risk of chimney fires.
Note that it is the chimney and not the stove which
creates the draft effect; your stove’s performance is
directly dependent on an adequate draft from your
chimney. The following recommendations may be
useful for the installation of your chimney:
1.
DO NOT CONNECT THIS UNIT TO A CHIMNEY
FLUE SERVING ANOTHER APPLIANCE.
2.
It must rise above the roof at least 3’ (0.9m) from
the uppermost point of contact.
3. The chimney must exceed any part of the
building or other obstruction within a 10’
(3.04m) distance by a height of 2’ (0.6m).
4.
Installation of an interior chimney is always
preferable to an exterior chimney. Indeed, the
interior chimney will, by definition, be hotter
than an exterior chimney, being heated up by
the ambient air in the house. Therefore the
gas which circulates will cool more slowly, thus
reducing the build-up of creosote and the risk
of chimney fires.
5. The draft caused by the tendency for hot air to
rise will be increased with an interior chimney.
6.
Using a fire screen at the extremity of the
chimney requires regular inspection in order to
ensure that it is not obstructed thus blocking
the draft, and it should be cleaned when used
regularly.
