ing system shall terminate at least 4 feet below, 4 feet
horizontally from, or 1 foot above any door, window,
or gravity air inlet into any building. The bottom of
the vent shall be located at least 12 inches above grade.
Termination of the vent shall be not less than 7 feet above
an adjacent public walkway. The vent terminal shall not be
installed closer than 3 feet from the inside corner of an L
shaped structure. Termination of the vent should be kept
at least 3 feet away from vegetation. The venting system
shall terminate at least 4 feet 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. (See Figure 11)
H,
Locate or guard the vent to prevent accidental contact with
people or pets.
Terminate the vent above normal snow-line. Avoid loca-
tions where snow may drift and block the vent. Ice or snow
may cause the boiler to shut down if the vent becomes
obstructed.
Under certain conditions, flue gas will condense, forming
moisture. In such cases, steps should be taken to prevent
building materials at the vent terminal from being dam-
aged by exhaust of flue gas.
E,
The venting system shall terminate at least 4 feet below any
eve, soffit, or roof overhang.
F. The venting system shall not terminate underneath any
deck, patio, or similar structure.
G. Put vent on a wall away from the prevailing winter wind.

Joining and Sealing the Vent Pipe:
The vent pipe needs to be both watertight and gastight. Seal all
joints and seams as follows:
A. For Z-Flex Z-Vent stainless steel vent pipe use a high tem-
perature silicone sealant rated for 550°F. The outside of the
male end and inside of the female end of the pipe must be
cleaned with brake cleaner before applying silicone bead.
