Finish Top - Heatilator BIR50-B Owner's Manual

N. Finish Top
• Slide the storm collar down over the chimney to the top
of the flashing. The storm collar must be installed 1 in. off
the chase top flashing to provide proper ventilation (Figure
8.17).
• Tighten the bolts of the storm collar and seal the storm
collar against the chimney with sealant. Be sure chimney
and offsets are properly supported.
• Apply a non-hardening waterproof sealant around the
chimney at the point where the storm collar will meet the
chimney just above the flashing (Figure 8.17).
• Attach the chimney cap onto the top of the chimney by
setting the female end of the cap onto the male end of the
last chimney section. Secure the cap by using four sheet
metal screws (provided, Figure 8.18.)
• Do not push down from the top portion of the cap as this
may damage the cap. Push from the lower section of the
cap if needed.
• The chimney cap top can be removed for chimney cleaning
as described in the Chimney Inspection & Cleaning section
(Section 3) of this manual.
