Chimney - Drolet NG1800 Austral Owner's Manual

CHIMNEY

Your wood stove may be hooked up with a factory built or masonry chimney. If you are using a
factory built chimney, it must comply with UL 103 or ULC S629 standards; 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. (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 draught problems, while a large flue favors 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 draught effect; your stove's performance is directly
dependent on an adequate draught 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' (0.9 mm) from the uppermost point of contact.
3. The chimney must exceed any part of the building or other obstruction within a 10'
(3.04 m) distance by a height of 2' (0.6 m).
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 draught 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 insure that it is not obstructed thus blocking the draught, and it should be cleaned
when necessary.
7. Follow pipe manufacturer's instruction to maintain an effective vapour barrier where
chimney or other component penetrates to the exterior of the structure.
