whichcreatesthedrafteffect;yourstove’sperformanceisdirectlydependentonanadequatedraft
fromyourchimney.
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’ (3.04m)
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 denition, 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 res.
5. The draft caused by the tendency for hot air to rise will be increased with an interior chim-
ney.
6. Using a re screen at the extremity of the chimney requires regular inspection in order
to insure that it is not obstructed thus blocking the draft, and it should be cleaned when
regularly.
