See Boiler Applications manual for additional venting information.
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 vent system must be installed upwards, never downwards,
completely nor partly.
Place pipe supports every 4 feet (1,219 mm) of horizontal run, beginning with
support near the boiler to prevent movement in fi ttings and allow boiler to be
free from any strain or weight on boiler or fi ttings.
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 fi g 19 and 20).
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.
Use the Instructions of the Rinnai venting system for installation and service.
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.
