Vent/Air Intake for Continuum V2532C Hot Water Systems
The only vent/air intake systems approved for use with this appliance by CSA are the Rinnai/Ubbink vent
system or the Heatfab Saf-T Vent SC vent system. The vent system must vent directly to the outside of
a building and use outside air for combustion as indicated in the diagrams below. The minimum and maximum
wall thickness for sidewall venting are: Minimum = 4" and Maximum = 20".
Horizontal Direct Vent Installation
The Continuum V2532C may be installed on the internal
surface of an external wall using a standard vent system
kit. A typical installation is shown in the diagram to the
right. The standard vent system kit consists of :
•
One vent termination kit
•
One discharge adaptor
Horizontal Extension Installation
The Continuum V2532C may also be installed on an internal
wall which is near to an external wall. This can be done using
a combination of extension tube(s), 90° or 45° elbow(s).
The maximum "EQUIVALENT LENGTH" of the vent/air intake
system is 41 feet, with a maximum of 3 bends, as
calculated using the formula on page 29 (i.e. an installation
with 23 feet of extension tubes, and three 90° elbows). The
maximum vertical height of the vent/air intake system shall
not exceed 5 feet unless an approved condensation collar
is used.
Vertical Direct Vent Installation
The Continuum V2532C can also be installed in roof spaces
or areas where vertical venting is required. Venting vertically
can be acheived using a combination of extension tube(s),
a vertical flue adaptor, a roof terminal, and flashing. The
maximum "EQUIVALENT LENGTH" of the vent/air intake
system is 41 feet, with a maximum of 3 bends, as
calculated using the formula on page 29. However, the
maximum HEIGHT of the vent system is limited to 21 feet.
The maximum vertical height of the vent/air intake system
shall not exceed 5 feet unless an approved condensation
collar is used.
