WARNING
Prolonged exposure to elevated temperatures is capable of inducing
hyperthermia. Hyperthermia occurs when the internal temperature of
the body reaches several degrees above the normal body temperature
of 98.6°F. The symptoms of hyperthermia include an increase in the
normal temperature of the body, dizziness, lethargy, drowsiness, and
fainting. The effects of the hyperthermia include failure to perceive
heat, failure to recognize the need to exit the room, unawareness of
impending hazard, fetal damage in pregnant women, physical inability
to exit the room and unconsciousness.
WARNING
The use of alcohol, drugs, or medication is capable of greatly
increasing the risk of fatal hyperthermia.

9/64" holes to fasten the heater brackets to the wall. Install two ¼" x 1
½" hex head lag screws (supplied with the heater) through the top holes
on the mounting brackets (one screw per bracket). Tighten these
screws. The screws must be threaded through the wall into a framing
member or backing board to support the heater weight. Locate the two
¼" x 1" hex head lag screws (supplied with the heater) then install them
into the two lower mounting holes. Tighten to lock the heater brackets
in place.
Place the heater on the wall brackets and fasten with screws. See
Diagram 1 & 2 for the heater location details and the necessary
SECTION 3: PLACING OF ROCKS
The rocks supplied with the heater have been chosen to provide the best
heater performance. Use of any other type of rock may void the heaters

Rinse the rocks with water before placing in the heater. Packing the
rocks too tightly may cause the heater high limit switch to trip. Follow
the below rock placement instructions. After completion, attach the
guard with the screws provided.
On a yearly basis, remove all rocks, clean rock fragments, and reinstall
reusable rocks. Follow the directions below for placement and the
High Limit
