Figure 3: Wind protection of air supply duct
WARNING
For operation independent of indoor air with RLU certified appliances, the outside air connection must be
connected.
For the dimensions of the air supply duct:
Air supply duct diameter
Maximum length
Max. number of 90° bends
100 mm
4 m
4
Note
If the dimensions are lower than specified, then it is not possible to operate the fireplace properly and it will
lead to increased contamination of the burner and inspection window.
5.4.1. Outside air connection (RLU)
To operate the stove independently of the air from the room, the combustion air must be supplied from the
outside or from an approved chimney system (e.g. LAS system).
5.5. Convection air distribution – Double Air
(only for stoves with a convection blower)
Depending on the specific variant of the stove, the hot air is either transported to the space in front of the stove
or it is piped to another heated space.
Hot air can be transported by the blower either directly to the stove installation room or to other rooms.
The temperature of the convection air at the outlet of the stove reaches a maximum of 120 °C.
The convection air duct to a room other than the stove installation room should be as short as possible, max. 8
meters long with a max. of 4 bends with a min. diameter of 80 mm.
WARNING
The pipe material must be made of heat-resistant, non-combustible material – risk of fire!
