F. Chimney Termination Requirements
Follow manufacturer’s instructions for clearance, securing
flashing and terminating the chimney, Figures 3.15 & 3.16.
• Must have an approved and Listed cap
• Must not be located where it will become plugged by
snow or other material
• Must terminate at least 3 feet (91 cm) above the roof
and
at least 2 feet (61 cm) above any portion of the roof
within 10 feet (305 cm).
• Must be located away from trees or other structures
NOTICE:
• Chimney performance may vary.
• Trees, buildings, roof lines and wind conditions affect
performance.
• Chimney height may need adjustment if smoking or
overdraft occurs.
E. Locating Your Appliance & Chimney
Location of the appliance and chimney will affect
performance. As shown in Figure 3.14 the chimney should:
• Install through the warm space 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
affects of wind turbulence and down drafts.
NOTICE:
Locating the appliance in a basement or in a
location of considerable air movement can cause intermittent
smoke spillage from appliance. Do not locate appliance near
• Frequently open doors
• Central heat outlets or returns
• Consider the appliance location in order to avoid floor
and ceiling attic joists and rafters.
•
Locate termination cap away from trees, adjacent
structures, uneven roof lines and other obstructions.
Your local dealer is the expert in your geographic area and
can usually make suggestions or discover solutions that will
easily correct your flue problem.
