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

- Concentricsystem

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 tted, with or without elbow pieces. The maximum

permissible pipe length is displayed in table 9, chapter 6.7.7.

- Parallelsystem

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 separate supplied

kit, with 2 vent adapters 3" (ø80mm), cover 5" (ø125mm), vent exhaust pipe and

gaskets should be tted instead of the concentric vent adapter on top of the boiler.

See chapter 6.7.3.1 for installation. The maximum permissible pipe length is set out

in table 9, chapter 6.7.7.

-RoomAirSystem(indoorcombustionair)

The boiler can use room air for combustion. If this option is selected the boiler must

rst be converted to the parallel system. A single exhaust pipe can then be tted.

It is required to use a room air lter (Part nr. 808000025) when using indoor air for

combustion. See chapter 6.7.3.2 for installation. The maximum permissible pipe

length is set out in table 9, chapter 6.7.7.
