Installation instructions
NOTICE:
▶ In areas where outside temperatures routinely come
close to freezing, sealed combustion operation is
required. Concentric termination or separate
terminations for combustion and vent, must be
installed on the same wall or roof surface; however,
never facing the direction of prevailing winds. Failure
to do so may result in heat exchanger freezing and
bursting. This failure is not covered under the
manufacturer's warranty.
WARNING: Appliance malfunction!
▶ Protect the exhaust and inlet from leaves and debris
by installing a screen on the end of the termination.
¼ " mesh minimum opening recommended on
screen.
4.3.1 Vent material
Establish vent clearances that comply with the vent manufacturer's
specifications. In all cases, follow local codes. See table 5:
Item Diam.
Exhaust Vent 3 or 4 inches
Intake Vent PVC
Table 5 Venting Specifications
Horizontal venting systems only:
An optional stainless concentric vent/air intake termination can be used
to provide only one penetration point through the exterior wall (see fig.
8, 9 & 10). The concentric vent/air intake kit can be ordered from your
local wholesaler. Note: Only tee terminals are approved for use with the
concentric vent/air intake kit (see Table 6). Vent piping and tee terminal
used with kit must be from the same vent pipe manufacturer. The
appliance can also be installed with separate air intake and exhaust
piping (see Fig.16).
