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 gen-
tly 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 small-
est 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 90C (194F).
