4.1.5 EXTENDED HORIZONTAL AND CORNER TERMINAL INSTALLATION
A 45° corner installation can have 0” rise between the appliance combustion
air collar and the air terminal. In this case, vent lengths must be kept to a
maximum of 24”. For longer vent lengths, a minimum vertical rise of 24”
is required.
A. Follow the instructions for "HORIZONTAL AIR TERMINAL INSTALLATION"
section.
B. Continue adding components alternating inner and outer vent pipes. Ensure that
all inner vent pipes and elbows have sufficient vent spacers attached and each
component is securely fastened to the one prior. Attach the telescopic sleeve to the
vent run. Secure and seal. 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.

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
high temperature sealant W573-0007 Mill Pac (not
supplied) to the inner sleeve of the air terminal. Slip
the vent pipe a minimum of 2” over the inner sleeve
of the air terminal and secure with 3 #8 screws.
B. Using the outer rigid pipe, slide over the outer combustion air
sleeve of the air terminal and secure with 3 #8 screws. Seal
using high temperature sealant 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. From inside the house, using silicone, seal between the vent
pipe and the fi restop. Then slide the black trim collar over the
vent pipe up to the fi restop.
E. If more vent pipe needs to be used to reach the appliance,
couple them together as illustrated. The vent system must be
supported approximately every 3 feet for both vertical and
horizontal runs. Use noncombustible strapping to maintain
the minimum clearance to combustibles.
The air terminal mounting plate may be recessed into the exterior wall or siding no greater than the depth of its
return fl ange.
