Codes require that solid-fuel chimneys extend 3 ft. (0.9 m) above the highest point at which they exit from the roof. Then, the chimney
must extend 2 ft. (6 m) above the highest point within a 10 ft (3 m) radius. Thus, the 3 foot, 2 foot, 10 foot rule:
•
3ft. - Above roof exit point
•
2ft. - Higher than anything within-
•
10ft. of the chimney.
NOTE: The restriction of not venting more than one appliance to the same flue applies to the U.S. specifically. While it is not
recommended that you use the same chimney for more than one appliance, in Canada certain exceptions may be made. Be sure to
contact your building code inspection official to see if this option is allowed in your area, and to find out the specific requirements for
such an installation.
Building codes require that solid-fuel chimneys extend 3 ft (0.9 m) above the point at which they exit from the roof, provided that no
part of any structure is within the top of the chimney, then the chimney must extend 2 ft (6 m) above the highest point with the 10 ft (3
m) radius top height. If there is not ten feet of clearance from the top of the chimney, then the chimney must extend 2 ft (6 m) above the
highest point with the 10 ft (3 m) radius.
3.5 EXISTING MASONRY CHIMNEYS
If you plan on using a preexisting masonry chimney, have it thoroughly
inspected and cleaned. Any faults which make the chimney unsafe and
unusable must be repaired prior to use. These can include improper
height, structural defects, blockages, inadequate clearance to
combustibles, unsealed openings into other rooms of the house, signs of
creosote or smoke leakage, a loose or absent clean-out door, or absence of
a liner.
When connecting to a masonry chimney, several provisions are standard.
First, whether the chimney connector is vented to the chimney through a
thimble or a breech pipe, neither must pass beyond the inner surface of
the chimney liner, and both must be firmly cemented in place with
refractory cement. (A thimble is a masonry pipe which is inserted through
the chimney wall, and is frequently the preferred method; a breech pipe is
a piece of steel pipe used the same way.) In Canada, a breech pipe has
ridges or protrusions to lock it firmly into the refractory cement. In either case, the chimney connector vents to the chimney through
the thimble or breech pipe.
