WARNING! Risk of Fire! You MUST maintain 2 in.
(51 mm) air space to insulation and other combustible
materials around the chimney system. Failure to do so
could cause overheating and fire.
The following steps should be skipped if using a
chase.
• Install roof flashing appropriate to roof pitch.
• Install round termination cap and storm collar.
• Nail the flashing to the roof. Keep gaps between the
flashing plate and the roof to a minimum.
• Caulk the flashing plate and roof junction as well as the
vertical seam on the flashing. All nail heads must be
caulked with a roofing sealant.
• Caulk the overlap seam of any exposed pipe sections
that are located above the roof line to prevent leaks.
Figure 8.12 Ceiling/Attic Construction
• Refer to Figure 8.11.
• Plumb from roof to center of chimney.
• Drive a nail up through roof to mark center of pipe.
• Measure to either side of nail and mark the 14-1/2 in. x
14-1/2 in. (368 mm x 368 mm) opening required.
• Measure opening on the horizontal; actual length may
be larger depending on roof pitch.
• Cut out and frame opening.
• Refer to Chapter 25 of the Uniform Building Code for
roof framing details.
Continue assembling the chimney sections up through the
ceiling firestops as needed. While doing so, be aware of the
height and unsupported chimney length limitations given un-
der Section 8.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.
