Sauna heater stones
- Sauna stones should be piled sparsely in order to enhance ventilation between the stones. Do not bend the heating
elements together or against the frame
- Stones are piled so that they cover the heating elements. Do not, however, pile a large heap of stones on the heating ele
ments.For a sufficient amount of stones refer to page 3. Any small stones in the package of stones must not be piled on the
sauna heater.
- Empty the stone compartment regularly, at least once a year in private use, remove small and broken stones and replace
them with new ones.
- In commercial use this operation must be performed at least every second month.
- Structural clay tiles are not allowed. They may cause damage to the sauna heater that will not be covered by the warranty.
- Do not use soapstone as sauna rocks. Any damages resulting from this will not be covered by the stove warranty.
- Do not use lava stone as sauna rocks. Any damages resulting from this will not be covered by the stove warranty.
DO NOT USE THE HEATER WITHOUT STONES.
LocatRemote controlling
The Heater can be remotely controlled by connecting a closed
contactor, which can be pulse triggered, to connectors 3 and 4
of a RJ10 circuit board. The recommended cable size is AWG 24
or 26. The maximum length of an AWG 24 cable is 200 m when
using a Trend controller.
The maximum length of an AWG 26 cable is 130 m when using
a Trend controller.
NOTE: Incorrect connections may break a circuit board.

Door switch
The door switch refers to the switch on the sauna door. This switch complies with regulations. Public and private saunas must
have a door switch, i.e. saunas where the heater can be switched on from outside the sauna, e.g. using an On/Off button or a
similar method.
