Sauna heater safety clearances
Table Safety clearances
Corner and wall installations:
The OLET 31 sensor is installed 40 mm from the ceiling on the centre line of the heater on a
wall. Alternatively, the sensor can be installed on the ceiling above the centre of the heater
– see 'middle installation' for
instructions. The heater must be secured to the floor or the sauna bench structure in order to keep the safety distances the
same.
Middle installation:
If the sauna heater is installed further than 60 mm off a wall or a corner, the installation method is always
middle installation. The heater must be attached to the benches or to a similar structure using a wall support. The OLET 31
sensor is always installed on the ceiling.
