Approval codes for installation of venting system
Terminals should be positioned as to avoid products of combustion entering
openings into buildings or other vents.
Maintain 12" of clearance above the highest anticipated snow level or grade
or, whichever is greater. Please refer to your local codes for the snow level in
your area.
The termination shall be at least 4 feet (1,220 mm) for the US and 6 feet (1,830
mm) for Canada distance from electric meters, gas meters, regulators and
relief equipment. (for room air application only)
Horizontal vent systems should always be installed sloping towards the boiler
(min. 21 mm/m, 1/4"/ feet), in order to avoid condensate retaining in the vent
system. With the condensate running back to the boiler the risk of ice forming
at the terminal is reduced.
The whole route of the exhaust vent system must be installed upwards, never
downwards, completely nor partly.
Place pipe supports every 4 feet (1219 mm) of horizontal run, beginning with
the support near the boiler to prevent movement in fittings and allow boiler to
be free from any strain or weight on boiler or fittings.
The terminal should be located where dispersal of combustion products is not
impeded and with due regard for the damage or discoloration that might occur
to building products or vegetation in the vicinity (see fig 15 and 16).
In certain weather conditions condensation may also accumulate on the outside
of the air inlet pipe. Such conditions must be considered and where necessary
insulation of the inlet pipe may be required.
In cold and/or humid weather water vapor may condense on leaving the vent
terminal. The effect of such 'water condensation' must be considered. The
terminal must be located in a place not likely to cause a nuisance.
Cellular or Foam core PVC, CPVC and Radel is not permitted for use with the
boiler.
The application of any type of insulation is prohibited for use with any Plastic
venting system.
