3.5.3 Flue Venting
This boiler is not certified for use with Type "B" vent nor with
boilers are dual certified as a Category II and Category IV appliances, as defined in
P-K SONIC™
, latest edition. The vent material must be as listed in the Table of Acceptable Materials for
Z21.13/CSA 4.9
Venting Systems in Section 3.5.1.2 above. The exhaust vent can be run horizontally or vertically.
Vent installations shall be in accordance with
, the Natural Gas and Propane Installation Code, or applicable provisions of the local building
CSA-B149.1
codes.
3.5.3.1 Vent Sizing
The vent must be sized in accordance with the
according to the vent manufacturer's recommendations. When using manufactured venting systems, consult
your vent supplier for correct sizing and structural support requirements.Table 3.5.3.1 Vent Design

3.5.3.2 Required Clearances
Conventional Vent Systems Clearances
The following termination clearance requirements are for
conventional non direct vent installations:
• The vent system shall terminate at least 3 ft. above a forced air inlet
located within 10 ft. horizontally.
• The vent system shall terminate at least 4 ft . below, 4 ft. horizontally
from or 1 ft. above any door, operable window or gravity inlet into any
building. The bottom of the vent terminal shall be at least 12 in. above
grade or highest expected snow line (if applicable).
• Through the wall terminations shall not terminate over public walkways
or over an area where condensate or vapor could create a nuisance or
hazard or could be detrimental to the operation of regulators, relief valves
or other equipment.
Direct Vent (Sealed Combustion) Systems Clearances
• The vent terminal shall be located at least 12 in. from any air opening
into a building. The bottom of the vent terminal shall be at least 12 in.
above grade. Both the vent and air intake terminals must be at least 12
in. above the highest expected snow line.
• Through the wall terminations shall not terminate over public walkways
or over an area where condensate or vapor could create a nuisance or
hazard or could be detrimental to the operation of regulators, relief valves
or other equipment.
• When multiple direct vent appliances are adjacent, the exhaust must
terminate at least 10 ft. horizontally or 3 ft. vertically from the air intake of
another appliance.

Do not locate intake or exhaust
terminations directly above a
walkway; dripping of condensation
can cause icing of the walking
surface. Maintain a minimum
clearance of 6 ft (1.83 m)
horizontally from any electric or
gas meter, regulator or relief
equipment.

Make sure that the weight of the
vent is not supported by the boiler
vent collar. The collar is not
designed to support the weight
of the vent. Horizontal vent
sections shall be supported in a
manner to prevent sags or low
spots where condensate can
collect. Structural supports must
be connected to building elements
of sufficient strength to withstand
the weight of the vent system and
any bending forces imposed by the
venting system.
