Warning

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 fire 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.

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.

SECTION 1: GENERAL INFORMATION

Note: Saunatonttu users: Please read “Section 6” to understand the

principles around which this heater is designed, and to understand the
sauna conditions it will create for you.

Inspect sauna regularly for

required maintenance to

heater, control and benches.

Replace wood surfaces which

show any signs of deteriora-

tion.

The heater opening gets

extremely hot during opera-

tion.

Keep clear of opening while

sprinkling water on the rocks.

Steam is very hot and forceful.

Close heater lid after use.

Minors should be adequately

supervised whenever near a

hot or warming sauna.

These heaters are UL approved for permanent installations and electrical
connections. Built with splash proof construction, the conducting parts

SECTION 2: MOUNTING SAUNA HEATER AND CONTROL

Carefully locate the heater according to the dimensions shown in Diagram 1.

The supplied mounting block and control must be located and mounted
according to Diagram 1B. (This is to prevent the control from being placed in
an unsafe location.)

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 heater’s
warranty. Never operate the heater without rocks in place! Rinse the
rocks with water before placing in the heater. Place the rocks loosely to
keep the elements vertical and so the 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.

SECTION 4: ELECTRICAL HOOK-UP

Warning

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.

Do not install a shower in

the sauna room.

Electric Shock Hazard -

High voltage exists within

this equipment. There are

no user serviceable parts in

this equipment. All installa-

tion and service to this

equipment should be per-

formed by qualified licensed

personnel in accordance

with local and national

codes.

Do not construct sauna

room so as to restrict air

flow through the bottom of

the heater.

Electrical installation must be made by a licensed electrician in accor­dance with the National Electrical Code and local regulations.

To determine the correct wire size, refer to Diagram 2. Use copper
supply wire only, suitable for minimum 90 degrees C. The heater must
be grounded! See the heater wiring diagrams for proper connections.

Remove screws from the back cover to gain electrical access. Refer to
Diagram 10.

SECTION 5: GUARD RAIL

To reduce the risk of injury (hot surface of sauna heater opening) install
the heater guard rail with the clearances and dimensions shown in
Diagram 1.

SECTION 6: THEORY of OPERATION

This heater is always ready and is designed to keep the rocks in the rock
chamber hot at all times using a “Continuous Power” setting of 100 Watts, 200
Watts or 300 Watts. This amount of energy is stored and accumulates in the
rocks while the lid is closed.

First time use or with rocks cold:

With the lid closed, turn the system on by pressing the Reset button on the
control. Next press the upper “>” right arrow until the 60 minute indicator
glows. The sauna heater will be close to operational temperatures in 1 hour.
Refer to Diagram 4 for Control Discription.

Normal Use:

Rocks are hot and lid is closed. Open the lid to allow the energy to transfer into
the room. Leave room and return in 5-10 minutes. The room temperature should
be 125 F - 135 F. Now the sauna is ready to use.

Sprinkle the water on as desired to personal preferences of temperature and
humidity. Wait a few seconds and add another ladle of water on rocks. The
humidity in the air will rise and make the room feel hot. Continue to add water
as desired. The room temperature will also rise. If air becomes uncomfortable,
close the lid and this will remove the heat source.

Warning

Minimum clearance from

heater to wooden surfaces

(benches, side walls,

heater fence etc.) is shown

in diagram 1.

Use only copper wire of

the size and type indicated

in the Heater Specifica-

tion Chart and the tem-

perature rating indicated

on the heater junction

box.

All heaters and controls

must be grounded per

NEC to prevent electrical

shock in case of unit

failure.

This heater is designed to have the lid open for a maximum of 60 minutes
for any sauna bath.

The steam is very hot and forceful. Please stay clear of opening while
sprinkling water on the rocks.

After sauna bath, the lid should be closed to allow the Continuous Power to
replenish the rock temperatures.

Tips: Continuous Power settings vs. time to replenish rock temperatures:
Use sauna 4 - 5 times a week, set on 300 W
Use sauna 2 - 3 times a week, set on 200 W
Use sauna 1 time a week, set on 100 W

Turn on Boost Power if lid will be open longer than 30 minutes during 1 session.
This will keep rocks hot to create steam.

Note: Sauna temperatures are typically measured one foot from the ceiling. The
Saunatonttu is designed to operate between 130 and 150 degrees F, although it
can achieve higher temperatures if allowed to heat with the lid open for an hour.

Electrical outlets or

receptacles must not be

installed in a sauna room.

A guardrail or fence is

required around the

heater to prevent burns

from accidental contact.

Safety Locking Lid

Locking Pin

Safety Locking Lid:

On the right hand side of the lid, there is pin with a wood knob. To release the lock, pull out on wood pin.
This will allow the lid to be moved. There are two locking positions, full open or closed.
