Location of the fi replace and chimney will affect perfor-
mance.
• Install through the warm airspace enclosed by the
building envelope. This helps to produce more draft,
especially during lighting and die-down of the fi re.

the effects of wind loading.
• Locate termination cap away from trees, adjacent
structures, uneven roof lines and other obstructions.
