5. Slide the starter pipe into the fireplace, matching the holes
in the plate to the holes in the fireplace.
6. Place the Adapter on the Mounting Plate lining up holes.
Using the 4 sheet metal screws included in the kit, secure
the Adapter and Mounting Plate into fireplace. After secur-
ing to the fireplace, tape down the Adapter edges to the top
of the fireplace with aluminum tape to prevent leakage.
7. Determine the location for the air register and fan housing
assembly. Cut a 7-5/8 in. x 13-5/8 in. (143 x 346mm) hole
between framing members (wall studs or floor joists). The
brackets can be rotated 180° and mounted to the back side
of the 2 x 4 if necessary. See Figure 11.6 on page 61.
NOTICE: The fan and electrical connections must be
accessible for servicing per local code requirements.
NOTE: If the fan housing is installed in a 2 x 4 wall, the
front of the housing will protrude approximately 1/4 in.
(6mm) from the finished wall. see Figure 11.5 on page
61.
8. Attach enough 6 in. (152mm) B-Vent as required for
your installation to the fan housing. A maximum of (4) 90°
elbows is recommended. Securely twist lock the B-Vent
to the Adapter.
Also screw the B-Vent to the outlet box on the fan housing.
See Figure 11.6 on page 61. Support duct at intervals of no
greater than 4 ft (1 m) as required by local code.
