A

Consult local and state codes pertaining to special building code and fire department requirements. Adhere to national code requirements.

Follow the listed maximum length of vent systems, which are boiler output dependent. The maximum permissible lengths are listed in table 9, chapter 6.7.6.

Decide how to install the exhaust and air intake system. You can choose between:

-Concentric system (see page 26)

The concentric connection is provided standard initially.

The boiler concentric connection diameter is 3"/5" (80/125 mm), to which the venting and air supply system can be fitted, with or without elbow pieces. The maximum permissible pipe length is displayed in table 9, chapter 6.7.6.

-Parallel system (see page 27)

The boiler can be converted to a parallel system with supplied adapters.

It is possible to use a parallel pipe connection of 2x 3". In this case a seperate supplied kit, with 2 vent adapters 3" (ø80mm), cover 5" (ø125mm), vent exhaust pipe and gaskets should be fitted instead of the concentric vent adapter on top of the boiler. See figure 12 for installation. The maximum permissible pipe length is set out in table 9, chapter 6.7.6.

-Room Air System (outdoor combustion air)

The boiler can use room air for combustion. If this option is selected the boiler must first be converted to the Parallel system. A single exhaust pipe can then be fitted. It is required to use a room air filter when using indoor air for combustion. The maximum permissible pipe length is set out in table 9, chapter 6.7.6.

We advise to install a vent system out of the venting system program supplied by Rinnai (See chapter 19 Parts list Vent system). For further information about the available components of the venting and air supply system we recommend you consult Rinnai and the Installation instructions and parts list documentation.
