Chimney Installation - Heatmaster G100 Operation And Maintenance Manual

Draft problems may occur because of incorrect chimney installation. Make sure to fol-
low these simple rules to ensure proper performance and safety.
1. The chimney must be connected using a minimum double wall stainless steel
chimney and connecter.
2. Use a direct exit whenever possible. A vertical exit with elbows is always the saf-
est and most trouble free installation.
3. Maximum chimney installation height is 15 ft.
4. Maximum horizontal installation from furnace to exhaust exit is 3 ft
5. Maximum 8 ft run from elbow to elbow but keep as short as possible.
6. Never use an elbow with a greater than 30 degree bend. 45 degree elbows and
tees cannot be used.
7. Elbows should never be installed in floor joists or roof and attic entries.
8. Shields should be used whenever going through floors, attics and roofs to keep
the wood and insulation from getting too hot and possibly catching fire.
9. Make sure to follow local building codes.

CHIMNEY INSTALLATION

Roof Penetrations and Clearances
The basic rule is this: the top of the chimney
must clear the roof penetration point (the upper
edge) by at least 3 feet and must clear anything
within a 10 foot radius by at least 2 feet. This in-
cludes: the peak of the house, parapet, dormer,
chimney, or spire. See diagram below.
If the chimney terminates beyond 10 feet from
the ridge of the roof it must clear the upper pen-
etration of the roof by 3 feet. Notice that the flue
still terminates 2 feet above the roof at the 10
foot perimeter:
