Fire Risk
• Secure offsets with screws (not to exceed
3/4 in./19 mm in length).
WARNING
• Secure returns with strapping.
• Straight chimney sections may be secured with screws
(not to exceed 3/4 in./19 mm in length) at the joints.
Keep chimney sections from separating or twisting.
F. Double-check the Chimney Assembly
Continue assembling the chimney sections up through the
ceiling fi restops as needed. While doing so, be aware of the
height and unsupported chimney length limitations given un-
der Section 5.A. Chimney Requirements.
Check each section by pulling up slightly from the top to en-
sure proper engagement before installing the succeeding
sections. If they have been connected correctly, they will not
disengage when tested.
G. Secure the Chimney
When offsets and returns are joined to straight pipe sections,
they must be locked into position with the screws provided*
(outer only), using the predrilled holes. To prevent gravity
from pulling the chimney sections apart, the returns and the
chimney stabilizers have hanger straps for securing these
parts to joists or rafters. See Figure 5.9.
