2. Locating Fireplace & Chimney
Location of the fireplace and chimney will affect perfor-
mance. To reduce spillage of combustion products into
the living space avoid:
• 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.
• Penetrate the highest part of the roof. This minimizes
the effects of wind loading.
• Minimize the use of chimney offsets.
• Consider the fireplace location relative to floor and ceiling
and attic joists.
Negative pressure in the structure can cause spillage of
combustion products into the living space. To minimize
effects of negative pressure:
• Ensure adequate outdoor air for all combustion
appliances and exhaust equipment.
• Ensure furnace and air conditioning return vents are not
located in the immediate vicinity of the fireplace.
• Avoid installing the fireplace near doors, walkways or
small isolated spaces.
• Recessed lighting should be a “sealed can” design.
