Heater Installation
Place the heater near the wall or as strategically is permissible. For safety and convenience, follow
the minimum safety distances as provided in Fig. 2. Follow the cubic volumes given in Fig. 6. Do
not install the heater to a wall niche. Do not install more than one heater in a sauna room unless
you follow the special instructions for twin-heater installations. In most countries, there is a law that
requires heaters to be screwed to the floor as provided in Fig 1.
The heater gets very hot. To avoid the risk of accidental contact with the heater, it is recommended
that a heater guard be provided.
A certified electrician must do the installation of the heater to ensure safety and reliability.
Improper electrical connection can cause electric shock or fire. Refer to the electrical diagram in
Fig.5.
