Stainless Steel Chimney Cover for GAK System
non UB Flex
Only the stainless steel pipe is UV proof and may be
exposed to the elements above the roof.
Adjust the last white pipe length so that the terminating
stainless steel pipe extends at least 11” (280mm) above
the top of the chimney crown where the cover will be
sitting. This will result in a minimum of 3” (75mm)
clearance of the pipe above the cap. The end pipe can
always be trimmed later.
Coat the gasket of the last white pipe and the mating
stainless steel pipe with CENTROCERIN® and assemble
using a slight turning motion.
Push the Chimney Cover over the terminating pipe. Using
a pair of snips, the chimney cover can be trimmed to size
to match the chimney crown.
Set cover on the chimney and mark 4 holes. Drill holes
and insert wall anchors. Caulk around the perimeter of
the cover to prevent rain water from entering the
chimney, then screw down firmly.
The steel cable attached to the cover is not being
used.
