Installation & Servicing Instructions Rinnai E-Series

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 ﬁ 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

ﬁ 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 ﬁ 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”/foot (21 mm/m) 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 speciﬁ c venting systems. The venting system

manufacturer's required venting pitch must always be followed if larger than

1/4” (21 mm). Ubbink concentric condensing venting requires a pitch of ¾”/

foot (6mm/m).

Combustion air piping from the outside MUST comply to the requirements

of the authority having jurisdiction or, in the absence of such requirements,

to the latest edition of the National Fuel Gas Code, ANSI Z223.1/NFPA 54. In

Canada, installation must be in accordance with the requirements of CAN/

CSA B149.1, Natural Gas and Propane Installation Code.
