Firestops
WARNING
: Many firestops are designed for a 1" clearance,
this fireplace requires a 2" clearance.
•
Whenever the chimney penetrates a floor or ceiling a
firestop is required on the bottom side of the floor joists
(see Figure 24).
•
When passing through an attic the firestop must be
placed on the attic side of the joists
•
When the chimney passes through a living space it must
be totally enclosed (maintain the minimum 2"
clearance to combustibles)
•
The space between frames that hold the firestop in
place should be measured as follows:
-- Temco
16"
-- Firecraft
16 1/2"
-- FMI
16 1/2"
-- Marco
16 1/2"

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 (see Figure 25). 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.
