4. THE CHIMNEY

4.1 CHIMNEY INSTALLATION NOTES

1. If possible, install an interior chimney as it will provide better performance. In areas with

continuous temperatures below −18° C (0° F), the use of an exterior chimney increases the

likelihood of operating problems such as low draught, high rate of creosoting, and poor

start-up characteristics. Exterior chimneys are also prone to down-drafting and flow

reversal. Installations, which are located on lower floors in the house, such as in a

basement, in combination with outside chimney, are especially prone to flow reversal.

2. The ENERZONE SOLUTION 2.5ZC is listed only with chimney systems described in

table 2.

3. A chimney venting a fireplace shall not vent any other appliance.

4. The minimum chimney system height is 15 ft. (4.6 m).

5. All chimney installations must include at least one support. Reducing the amount of

chimney weight on the fireplace will help avoid the noise created when the fireplace

expands. This can be achieved by having the chimney supported by the supports. The

maximum chimney length that should be supported by the fireplace is 9 ft. (2.75 m) for 2"

Solid Pack Chimney, 12 ft. (3.7 m) for 1" Solid Pack Chimney, and 26 ft. (8 m) for AC

Triple Wall Chimney.

6. The chimney must extend at least 3 ft. (1 m) above its point of contact with the roof and at

least 2 ft. (0.6 m) higher than any wall, roof or building within 10 ft. (3 m) of it (Figure

21).

7. If the chimney extends higher than 5 ft.

(1.5 m) above its point of contact with the

roof, it must be secured using a roof

brace.

8. A rain cap must be installed on top of the

chimney. Failure to install a rain cap may

cause corrosion problems.

9. Cut and frame square holes in all floors,

ceilings, and roof that the chimney will go

through to provide a 2" (50 mm)

clearance between the chimney and any

combustible materials. Do not fill this 2″

space with insulation or any other

combustible material.

10. Portions of the chimney which may

extend through accessible spaces must be

enclosed to avoid contact with

combustible materials or damage the

chimney.
