1. Assembling Slim Line Trim Ring and Heat Shield
2. Installing Slim Line Trim Ring and Heat Shield
Figure 5.31 Lay the trim ring on flat surface and bend up the
six welded 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 5.32 The heat shield is shipped flat and must be hand
bent into a half circle before attaching it to the trim ring.
Bend the heat shield as shown.
NOTE: Wear leather gloves when bending the heat shield
to prevent injury.
Figure 5.33 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.
Figure 5.34 When installing the trim ring/heat shield assem-
bly make sure the trim ring is centered in the hole and that
the shield is above the pipe. There must be a minimum of
3/4 in. (19mm) minimum clearance maintained to combus-
tibles from the top of the heat shield.
Measure from the floor to the center of the vent pipe. Cut out
a 9-1/2 in. (241mm) 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.
See 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 mini-
mum inner framing diameter of 10 in. x 10. in. (254mm x
254mm).
The four trim ring mounting screws provided should be
replaced with appropriate fasteners for stucco, brick, con-
crete, or other types of sidings.
