WARNING!

* Hyperthermia occurs when the internal temperature of
the body reaches a level several degrees above the normal
temperature of 98.6° F. The symptoms of hypothermia include
an increase in the internal temperature of the body, dizziness,
lethargy, drowsiness and fainting. The eff ect of hyperthermia
include:
a) Failure to perceive heat;
b) Failure to recognize the need of exit the room;
c) Unawareness of impending hazard;
d) Fatal damage of pregnant women;
e) Physical inability to exit the room; and
f) Unconsciousness

• Do not take a sauna if using alcohol, drugs or medica­tions.

• Pregnant women or persons with poor health should con­sult their physician before using any sauna.

• Caution fi re hazard: Do not use the sauna room for drying
clothes, bathing suits, etc. Do not hang towels above
heater or place any object other than the rocks supplied
on the heater. If any darkening of the wall around the
heater is noticed discontinue sauna use immediately.

• Inspect sauna regularly for required maintenance to heat­er, control and benches. Replace wood surfaces which
show any signs of deterioration.

brackets supplied. Provides proper clearance from wall
behind heater.

• Use only copper wire of the size and type indicated in the
Heater Specifi cation Chart and the temperature rating
indicated on the heater junction box.

• A guardrail or fence is required around the heater to pre­vent burns from accidental contact.

• The heater gets extremely hot during operation and
should not be touched or burns may result.

• Minors should be adequately supervised whenever near a
hot or warming sauna.

• Fire sprinkler systems used inside any sauna room should
be properly rated for sauna room temperatures.

• Do not pour chlorinated pool or spa water on heater.
Excessive water use on heater may cause damage and
void warranty.

• This appliance is not intended for use by persons (includ­ing children) with reduced physical, sensory or mental
capabilities, or lack of experience and knowledge, unless
they have been given supervision or instruction concern­ing use of the appliance by a person responsible for their
safety. Children should be supervised to ensure that they
do not play with the appliance.

• All heaters and controls must be grounded per NEC to
prevent electrical shock in case of unit failure.

• Electrical outlets or receptacle must not be installed in a
sauna room.

Installation requirements

To ensure safe use of the heater, check that the following criteria
are met:

• Electrical wiring should be installed in accordance with NEC
and all state and local codes.

• Fuse size (A) and power cable size (AWG) must be suitable
for the heater (see The section called Connection/wiring
diagram, Page 9.

• The sauna ventilation must comply with the instructions in
this manual (see The section called Positioning the inlet vent,
Page 5, The section called Positioning the outlet vent, Page

5).

• The position of the sauna heater, control panel, and sensors
must comply with the instructions in this manual.

• The heater output (kW) must be suitable for the sauna
volume (cu.ft.) (See Table 1, Page 3). The minimum and
maximum volumes must not be exceeded.

• NOTE: A GFCI device is not required by ETL. A GFCI may
be installed if required by local codes. However, GFCI devic­es will tend to nuisance trip during use of the product.

The control panel can be installed inside or outside of the sauna
room.

The control panel must be correctly positioned with regard to
safety distances below when installed inside the sauna room

Positioning the heater - normal installation

Position the sauna heater:

• on the same wall as the door (or the side wall if very close to
the door wall).

• Position the heater at a safe distance from the fl oor, side
walls and interior fi ttings (see Figure 3).

Position the sensor according the picture (see Figure 3).

Sauna room ventilation

Compliments of www.saunasandstuff.com

In a sauna, the air should be changed about 6 times an hour. See
Figure 6.

It is recommended that ventilation openings meet the require­ments of UL Specifi cation 875. The minimum opening should be
determined using one of the following formulas:
For R< 31, V ≥ 9 .3
For R ≥ 31, V ≥ 0.3*R

where R = the fl oor area of the room in square feet and
V = the minimum vent size in square inches

ExampleVenting Calculation:
Room is 54 sq.ft.(9 ft. by 6 ft.) 54 is larger than 31.
Multiple 54 x 0.3 = 16.2 sq. in.
Vent size opening should be 4 in x 4 in.

Positioning the inlet vent

Install the inlet vent straight through the wall under the centerline
of the heater.

Removing the Rock Guard

Unscrew the two screws on the side of the heater and lift the
rock guard upwards, see Figure 7. (This is necessary when fi lling
the stone compartment or cleaning the fragrance holder and air
humidifi er).

Figure 6: Positioning the air intake and exhaust vents

1. Inlet vent position.

2. Outlet vent position through the sauna wall.

3. Outlet vent position through the cavity.

4. Outlet vent position via duct.

Positioning the outlet vent

Position the outlet vent

• at the maximum possible distance from the air intake vent,
e.g. diagonally (see Figure 6).

• high on the wall or in the ceiling (see Figure 6).

• so that it vents into the space that the door and air intake
vent open into.

Figure 7: Removing the Rock Guard

Room construction

For safety and reliability, the following rules must be addressed.

• The enclosed WARNING: Reduce the risk of overheating
… warning plate must be mounted on or alongside the door
outside the sauna room at about eye level. Use the supplied
screws.

• The enclosed CAUTION: Reduce the risk of fi re … caution
plate must be mounted on the interior wall above the heater.
Use the supplied screws.

• No permanent locking or latch system is to be used on the
sauna door.

• Acceptable door fi ttings are: magnetic catches, friction catch­es, spring or gravity loaded closures. The door must always
open outwards.

• No shower may be installed in a sauna room.

• No electrical receptacle shall be installed inside the sauna
room.

• The heater should not be operated without its container prop­erly fi lled with rocks and the rock guard in place.

• If an intercom speaker is installed, it should be away from the
heater and as close to the fl oor as possible.

• If a room light is installed, it should be a surface mounted
bracket type. Wall mounted lights should be about 70” above
the fl oor. Ceiling mounted lights should be of an approved
type with a junction box that is remote to the fi xture itself.
Use only a fi xture that uses A.F. or fi xture type internal wiring.
A 60 watt bulb should provide suffi cient lighting.

• Fire sprinkler systems installed inside any sauna room should
be properly rated for sauna room temperatures.

• Always mount the heater according to these installation
instructions.

The outlet vent must have the same area as the inlet vent.
Ensure that the outlet vent is open.
Mechanical ventilation is not recommended due to the risk of poor
air exchange, which can negatively aff ect the heater temperature
cut-out.
