brackets into a 90 degree position. The brackets along the
outer edge of the ring are for locating the ring in the center
of the hole.

Figure 7.17
Attach the heat shield to the trim ring with the four screws
provided. Screws go through the heat shield and into the
brackets on the trim ring.
2. Installing Slim Line Trim Ring and Heat Shield
Measure from the floor to the center of the flue pipe. Cut out
a 9-1/2 in. (240 mm) 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 previous page.
Use that mark as a guide to trim off excess heat shield with
a pair of sheet metal shears.
Figure 7.18
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 20 mm
minimum clearance maintained to combustibles from the
top of the heat shield.
Ensure that framing on the inside of the wall is a minimum
inner framing diameter of 9 in. x 9 in. (229 mm x 229 mm).
The four trim ring mounting screws provided should be
replaced with appropriate fasteners for stucco, brick,
concrete, or other types of sidings.
