venting installation
3.2.5 horizontal air terminal installation
3.2.6 extended horizontal and corner 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 2” (50.8mm) overlaps between venting
components.
B.
Apply a heavy bead of Mill Pac sealant
(W573-0007) (not supplied) to the outer edge of
the inner collar of the appliance. Attach the fi rst
inner rigid pipe component and secure using a
minimum of three 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.

Do not allow loose materials or insulation to touch the vent pipe. Remove insulation to allow for the installation
of the attic shield and to maintain clearances to combustibles.

WARNING
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.
