Figure 5.17
When installing the trim ring/heat shield assembly make
sure the trim ring is centered in the hole and that the shield
is above the pipe. There must be a minimum of 2 cm mini-
mum clearance maintained to combustibles from the top of
the heat shield.
Measure from the fl oor to the center of the fl ue pipe. Cut
out a 25.4 cm hole in the wall. Hold the trim ring/heat shield
assembly in place and put a mark on the shield with a black
marker where it protrudes through the exterior wall. Figure
A on the next page.
Use that mark as a guide to trim off excess heat shield with
a pair of sheet metal shears.
Ensure that framing on the inside of the wall is a minimum
inner framing diameter of 25.4 cm x 25.4 cm.
The four trim ring mounting screws provided should be
replaced with appropriate fasteners for stucco, brick, con-
crete, or other types of sidings.
