venting installation
4.3.4 horizontal air terminal installation
4.3.5 extended horizontal and corner air terminal installation
A.
Move the appliance into position. Measure the vent length
required between terminal and appliance taking into account
the additional length needed for the fi nished wall surface and
any 1¼” (31.8mm) overlaps between venting components.
B.
Apply a heavy bead of Mill Pac sealant (W573-0007) (not
supplied) to the outer edge of the inner exhaust fl ue collar of
the appliance. Attach the fi rst inner rigid pipe component and
secure using a minimum of three #8 screws. Repeat using the
outer rigid pipe. Seal using Red RTV Silicone (W573-0002) (not
supplied).
C.
Insert the vent pipes through the fi restop maintaining the
required clearance to combustibles. Apply a heavy bead of
Red RTV Silicone (W573-0002) (not supplied) to both the inner
sleeve and outer sleeve of the air terminal. Slide the terminal
sleeves into the rigid pipes a minimum of 1 1/4”. Holding the
air terminal (lettering in an upright, readable position), secure
to the exterior wall and make weather tight by sealing with
caulking (not supplied).
The air terminal mounting plate may be recessed into the exterior
wall or siding no greater than the depth of the return fl ange.

FOR REAR VENT ONLY:
A 45° corner installation can have 0” (0mm)
rise between the appliance combustion air collar and the air terminal.
In this case, vent lengths must be kept to a maximum of 24” (61cm).
For longer vent lengths, a minimum vertical rise of 24” (61cm) is required.
A.
Follow the instructions for "horizontal air terminal installation" section.
B. Continue adding components alternating inner rigid pipe and outer
rigid pipe. Ensure that all inner rigid pipe and elbows have sufficient
vent spacers attached and each component is sealed and securely
fastened to the one prior. Attach the inner telescopic sleeve to the
vent run. Repeat using the outer telescopic sleeve. Seal and secure
as before. To facilitate completion, attach inner and outer couplers
to the air terminal.
C. Install the air terminal. See “horizontal air terminal installation” section.
Extend the outer telescopic sleeve; connect to the air terminal assembly.
Fasten with self tapping screws and seal.
