4.3 HORIZONTAL AIR TERMINAL INSTALLATION
EN
TERMINALS MUST NOT BE RECESSED INTO A WALL OR SIDING MORE THAN THE DEPTH OF THE
DO NOT ALLOW THE INNER FLEX PIPE TO BUNCH UP ON HORIZONTAL OR VERTICAL RUNS AND
A.
Stretch the inner fl ex pipe to the required length taking
into account the additional length needed for the
fi nished wall surface. Apply a heavy bead of the Mill
Pac sealant (W573-0007) (not supplied) to the inner
sleeve of the air terminal. Slip the vent pipe a minimum
of 2" (50.8mm) over the inner sleeve of the air terminal
and secure with a minimum of 3 screws.
B.
Using the outer fl ex pipe, slide over the outer
combustion air sleeve of the air terminal and secure
with a minimum of 3 screws. Seal using red RTV
silicone (W573-0002) (not supplied).
C.
Insert the vent pipes through the fi restop maintaining
the required clearance to combustibles. 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).
D.
If more vent pipe needs to be used to reach the
fi replace, couple them together as illustrated. The
vent system must be supported approximately every
3 feet (0.9m) for both vertical and horizontal runs. Use
noncombustible strapping to maintain the minimum
clearance to combustibles.
E. Stove Appliances Only: From inside the house, using Red
RTV Silicone (W573-0002) (not supplied), seal between
the vent pipe and the fi restop. Then slide the black trim collar over the vent pipe up to the fi restop.
The air terminal mounting plate may be recessed into the exterior wall or siding no greater than the
depth of its return fl ange.
4.4 EXTENDED HORIZONTAL AND CORNER AIR TERMINAL INSTALLATION
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
INSTALLATIONS" 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.
