CHIMNEY
Your wood appliance 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 speci
fi
cations.
If you are using a masonry chimney, it is important that it be built in compliance with the speci
fi
cations of the National Building
Code. It must be lined with
fi
re clay bricks, metal or clay tiles sealed together with
fi
re cement. (Round
fl
ues are the most ef
fi
cient).
The interior diameter of the chimney
fl
ue must be identical to the appliance smoke exhaust. A
fl
ue which is too small may cause
draft problems, while a large
fl
ue favours rapid cooling of the gas, and hence the build-up of creosote and the risk of chimney
fi
res.
Note that it is the chimney and not the appliance which creates the draft effect; your appliance’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
fl
ue 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 de
fi
nition,
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
fi
res.
5. The draft caused by the tendency for hot air to rise will be increased with an interior chimney.
6. Using
a
fi
re screen at the extremity of the chimney requires regular inspection in order to insure that it is not obstructed thus,
blocking the draft. It should be cleaned when used regularly.
7. Exterior chimney should be double or triple wall.
