NOTICE

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 finished 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 fittings. 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 fire, 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 specific 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.
