requirements. Adhere to national code requirements.
i
Follow the listed maximum length of vent systems, which are boiler output dependent.
NOTICE
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:
-
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.
-
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 14 for installation.
The maximum permissible pipe length is set out in table 9, chapter 6.7.6.
-
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
NOTICE
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
