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 is not permitted for use with the boiler.
6.7.5 Dimensioning of the exhaust and air intake duct
The wall mounted boiler must be vented and supplied with combustion and
ventilation air as described in this section.
Ensure the vent and air piping and the combustion air supply comply with
these instructions regarding vent system, air system, and combustion air
quality.
Inspect nished vent and air piping thoroughly to ensure all are airtight and
comply with the instructions provided and with all requirements of applicable
codes.
Failure to provide a properly installed vent and air system may cause severe
personal injury or death.
Use only the material listed in Rinnai's vent documentation for vent pipe, and
ttings. Failure to comply could result in severe personal injury, death or
substantial property damage.
Installation must comply with local requirements and with the National Fuel
Gas Code, ANSI Z223.1 for U.S installations or CSA B 149.1 for Canadian
installations.
For closet and alcove installation, CPVC material (instead of PVC) must be
used in a closet/alcove structure. Failure to follow this warning could result
in re, personal injury, or death.
All vent pipes must be connected and properly supported, and the exhaust
must be pitched a minimum of a 1/4” inch per foot back to the boiler (to allow
drainage of condensate). Please refer to the venting manufacturer's manual
to see if a larger pitch is required for specic venting sytems.
For the Room Air System, combustion air piping from the outside MUST BE
used. Use of combustion air from indoor rooms using louvers, plenums, or
any other devices is not authorized.
See the Rinnai Boiler Applications Manual for further information on venting.
