CHIMNEY INSTALLATION
(CONTINUED)
:
15) STRAIGHT CHIMNEY SECTIONS
– Before running
the straight chimney through the roof, slide the
Firestop Spacer (shown in FIG. 16) over the Return
Elbow. Now, snap the remaining Straight Chimney
sections into place.
If the chimney is 30’ or higher, a support section (a
4‐strap x 12” length of pipe) is required after a
straight chimney section above the fireplace run, or
above a Return Elbow. The support section will sup‐
port the increased weight of the chimney.

FIRESTOP SPACERS
16) FIRESTOP SPACERS
– Firestop Spacers are required at
each point where the chimney penetrates a floor or ceil‐
ing joist space. Attach Firestop Spacer to joist using wood
screws.
If the chimney pipe passes through a framed opening into
an attic space, the Firestop must be placed in the attic
floor. When the pipe passes through a framed opening
into living space above, the Firestop must be placed onto
the ceiling from below.
Refer to local building codes and restrictions for varia‐
tions in Firestop spacer requirements.
17) CHIMNEY ROOF FLASHING
– A flat Chimney Roof Flash‐
ing is used for flat roofs and chimney chases. For pitched
roofs a pitched flashing is used. Slide the Chimney Roof
Flashing down over the last section of straight chimney
penetrating the roof or chase and attach to roof.

If an exposed portion of chimney is greater than 5’
above the roof line, use support wires to keep chimney secure.
The support wires may be attached to the outer pipe of the
chimney with screws but must not penetrate the inner flue pipe.

DO NOT SEAL VENTILATION OPENINGS ON THE ROOF
