Framing the Roof
•
Follow the manufacturer's instructions for the use of flashing and an
adjustable storm collar at the roof line to prevent water from entering the
house.
•
The table below may be used to determine the appropriate framing size.
When installing into a sloped roof, it is important to determine the size of
the framing for clearance purposes. Use the appropriate column for 2 x 4 or
2 x 6 rafters. It is not necessary to frame around the hole opening if the
clearance to combustibles can be maintained between two rafters.

Chimney Termination Requirements
•
The chimney must terminate a minimum 3' above the roof and 2' above any portion within 10' (measured horizontally).
This applies to flat and sloped roofs.
•
The chimney must have a
chimney cap
•
When using a chase to enclose a
chimney, the chimney termination
is not required to be 3' above the
chase as long as the chase is
above the roof structure. The
chimney cap must still maintain
the 2, 3, 10 clearance to any other
structure. See the illustration to
the right.
•
Chimneys extending beyond a
certain height (frequently 5')
above the roof may require braces
(check the chimney instructions
for details)
?
In some problematic situations,
additional chimney height above
the specified minimums may be
necessary to reduce wind-induced
down drafting and back puffing,
or to increase draft, thereby
improving fireplace operating
characteristics.
