Install Instructions

f. Once the installation is complete, operate
appliance and inspect all joints to ensure that flue
gases and/or liquid condensate will not escape.
2. Procedure for joining the female end of Gasket-
Less Vent with the male end of Gasketed Vent. See
Figure 4D.
a. Clean joints of pipe or fittings using an alcohol
pad to remove any dirt and grease.
b. Slip a locking band over female (bell) end of
pipe/fitting.
c. Apply a continuous ¼ inch bead of sealant
around male end of joint no more than 1/8 inch
from end.
d. Align weld seams in pipes and use a slight
twisting motion to FULLY insert male end into
female end of joint.
e. Smooth sealant around joint for a continuous
seal. Reapply sealant if necessary.
f. Slip the locking band over joint and align closest
bead in locking band with bead in male end of
pipe.
g. Tighten locking band by HAND with a 5/16"
nut driver until snug plus ¼ turn. DO NOT
SECURE JOINTS WITH SHEET METAL
SCREWS OR POP RIVETS. DO NOT
PUNCTURE THE VENT SYSTEM!
h. Once the installation is complete, operate
appliance and inspect all joints to ensure that flue
gases and/or liquid condensate will not escape.

Gasketed Male Vent Joint Detail
H. Horizontal (Through Wall) Vent Installation.
1. Maintain minimum ¼ inch per foot slope in
horizontal runs. Slope pipe down toward vent
terminal. Position weld seams in vent pipes in all
horizontal runs at the top to avoid condensate from
lying on the seams.
2. Vent terminal location restricted per following:
a. Minimum 12 inches above grade plus normally
expected snow accumulation level, or 7 feet
above grade if located adjacent to public
walkway. Do not install over public walkway
where local experience indicates condensate or
vapor from Category III appliances creates a
nuisance or hazard.
b. Minimum 3 feet above any forced air inlet
located within 10 feet.
c. Minimum 4 foot below, 4 foot horizontally from,
or 1 foot above any door, window, or gravity air
inlet.
d. Minimum 4 feet (6 feet in Canada) horizontally
from, and in no case above or below, unless a
4-foot horizontal distance is maintained, from
electric meters, gas meters, regulators and relief
equipment.
e. Minimum 12 inches from overhang or corner.
3. Use wall thimble when passing through combustible
outside wall (thimble use optional for noncombusti-
ble wall). Insert thimble through wall from outside.
Secure outside flange to wall with nails or screws,
and seal with adhesive material. Install inside flange
to inside wall, secure with nails or screws, and seal
with adhesive material.
4. For noncombustible wall when thimble is not
used, size opening such that female (bell) end with
locking band attached cannot pass through.
5. Join vent terminal to vent pipe. Locate vent
terminal 3 inches (minimum) and 6 inches
(recommended) from wall when joined to inside
vent piping. See Figure 5. Vent terminal clearance
to vinyl wall surfaces is 6 inches.
6. Insert vent pipe through thimble/opening from
outside and join to vent system. Apply sealant
between vent pipe and opening/thimble to provide
weathertight seal.
