Venting must be ULC S636 certied for use as venting
material. The venting material class must be chosen
based upon the intended application of the unit and
must be installed according to the maximum ue gas
temperature and the vent manufacturer’s instructions.

2.C Vent and Air Pipe Sizing
This unit is certied to vent as a Category II or Category
IV appliance. Because Category II vent is non-positive,
the vent size may not be the same as the positive
pressure Category IV vent, even when the unit is the
same size. Be sure to follow the instructions in this
manual, based on the type of venting in your installation.
The venting must be correct to allow the condensate
to run back to the unit to drain. Route the vent pipe to
the boiler as directly as possible. Seal all joints. Provide
adequate hangers as required in the venting system
manufacturer’s Installation Instructions, or at least every
4 feet.
The unit must not support the weight of the vent pipe.
The maximum equivalent pipe length allowed is
100 feet (30m). Each elbow is considered to be 5 feet
(1.5m). The manufacturer o󰀨ers accessory kits to use
with horizontal and vertical exhaust vent systems, as
shown in Table 7.

NOTE: For Category II and IV boilers, the horizontal
runs must be sloping upwards not less than 1/4 inch per
foot (21 mm/m) from the boiler to the vent terminal, so
as to prevent accumulation of condensate and, where
necessary, have the means provided for drainage of
condensate.
ATTENTION: Pour la catégorie II & IV, les chaudières
ont horizontal en pente vers le haut au moins 1/4 de
pouce par pied (21 mm/m) à partir de la chaudière
pour l’évent borne; être installé de façon à éviter
l’accumulation de condensats; et, le cas échéant, ont
des moyens prévus pour l’évacuation des condensats.
NOTE: The use of PVC or CPVC schedule 80 is not
permitted.
