9.2 Minimum Chimney Height
The top of the chimney should be tall enough to be above the air turbulence caused when wind
blows against the house and its roof. The chimney must extend at least 3 ft. (1 m) above the
highest point of contact with the roof, and at least 2 ft. (60 cm) higher than any roof line or
obstacle within a horizontal distance of 10 ft. (3 m). The total system height, from the floor the
appliance is mounted on to the top of the chimney, should never be less than 15 feet (4.6 m).
9.3 Chimney Location
The location of the chimney is crucial for the proper functioning of the appliance. The chimney
should be installed within the house rather than up an outside wall and should rise straight up
through the tallest part of the house. This installation benefits from being enclosed within the
warm house environment, produce stronger draft, accumulate fewer creosote deposits and will
be unaffected by cold temperatures or harsh winds.
Outside chimneys will lead to cold back drafting when there is no fire in the stove, slow kindling
of new fires, and smoke roll-out when the door is open for loading.
On the other hand, excessive draft will make the fire uncontrollable, creating very high
temperatures in the unit as well as in the chimney and seriously damaging them. A reddish glow
on the unit and on the chimney components indicates overheating. Excessive temperatures can
cause a chimney fire.
