Locating Fireplace & Chimney - Heatilator A36C Installation Manual

2. Locating Fireplace & Chimney
Location of the fireplace and chimney will affect perfor-
mance.
• Install within the warm airspace enclosed by the building
envelope. This helps to produce more draft, especially
during lighting and die-down of the fire.
• Installing the fireplace in a basement is not recommended.
• Penetrate the highest part of the roof. This minimizes
the effects of wind loading.
• Locate termination cap away from trees, adjacent
structures, uneven roof lines and other obstructions.
• Minimize the use of chimney offsets.
• Consider the fireplace location relative to floor and ceiling
and attic joists.
• Take into consideration the termination requirements in
Sections 4 and 5.
Location NOT recommended:
• Not the highest point of the roof
• Wind loading possible
