Sauna Owner’s Manual
2.1kW and 8.0kW Heaters
These heaters are UL approved for permanent installations and electrical connections. Built with
splash proof construction, the conducting parts are protected against water. All wiring must be
performed in accordance with local codes. These heaters are wall mounted and have built-in controls.
Mounting of the Sauna Heater
Using the heater mounting bracket as a guide, drill 4 1/8” holes to fasten the bracket on the wall.
Attach the bracket with the 1/4” x 1 1/2” screws supplied with the heater. The screws must be threaded
through the wall into a framing member or backing board to hold the heater weight.
The heater is reversible. You can choose to locate the heater timer and thermostat controls on either
the right or left side for easy operation. To reverse the heater, simply remove the rock guard from the
top of the heater, rotate them and reinstall.
Line up the four holes at the bottom of the heater with four lugs on the mounting bracket. Push the
heater gently towards the wall, so the lugs of the mounting bracket pass through the four holes in the
heater. Fasten the heater to the mounting bracket using the two #8 sheet metal screws provided with
the heater.
Placing of Rocks
The rocks supplied with the heater have been chosen to provide the best heater performance. Use of
any type of rock other than those provided will void the heater’s warranty. Never operate the heater
without rocks in place.
Rinse the rocks with water before placing them in the heater. Place the larger rocks at the bottom and
the smallest at the top. Place the rocks loosely so that air can circulate through the heater. Packing the
rocks too tightly may cause the heater high limit switch to trip. The rocks must fully cover the heating
elements. Attach the guard with the screws provided.
Electrical installation must be made by a licensed electrician in accordance with the National Electrical
Code and local regulations.
Remove the heater’s electrical box cover and connect the feed with wires to the terminal block. Use
only copper wire, suitable for a minimum of 90 degrees C (194 degrees F).
