Sauna Craft Heater & Control
Installation Manual
NOTES FOR ALL HEATERS
Heater Guard Fence:
A non-metallic guard (not included) shall be provided and installed as follows:
a) 4” from CW Series heaters
b) 6” from FM Series heaters
Sauna Rocks (included):
1) Wash the rocks before placing on heater.
2) Do not pack rocks too tightly into rock tray. There should be pockets of air. Stack
rocks loosely in a “pyramid” like pile. Packing rocks too tightly will trap heat and
cause the hi-limit to trip.
3) These units must not be operated without the igneous rocks in place
Water:
Do not soak the heater with water. Water should be used in moderation Sprinkling with a ladle is
recommended.
Manual Reset High Limit Control:
1) This safety device must not be by-passed in the wiring of this sauna heater.
2) Should the high temperature limit control trip frequently, a qualified serviceman should be
contacted.
• A licensed electrical contractor should do all electrical work.
• Do NOT use a G.F.I breaker.
• All cables used in the installation of these units must be rated for 300 VAC.
• All cables supplied and connected to these units must be rated for 90o Celsius.
FIRST TIME USE
When using the sauna for the first time it is normal to have a little smoke. The elements are
burning off oil residue left by the manufacturing process. Turn the sauna on for ½ hour,
leave the door open and do not go inside.

CW SERIES HEATER (4 - 9 kw)
SAUNA CRAFT “CW” heaters can be installed on a straight wall or in a corner of the
sauna room by means of TWO mounting brackets. The unit should be placed 6”
(minimum) from the floor, 45” (minimum) from the ceiling and 2” (minimum) from
vertical surfaces (walls) and the minimum ceiling height must be 78”.
A non-metallic guard shall be provided and located not closer than 4” from the sauna
heater.
Determine where the unit is to be located. Mark the locations for the top two angled
brackets on the back of the unit. Fasten the mounting brackets using the 1-1/2”
mounting screws (supplied). Be sure that the screws pass through the lining and into
reinforcing studs in order to hold the weight of the unit (approx. 60lbs. with the rocks).
Then simply hang the heater on the mounting brackets.
NOTE: THERE ARE ONLY TWO BRACKETS.
The controls are recessed into the outside wall of the sauna, preferably beside the
door. Only the sensor bulb is located inside the sauna 3’ to 4’ from the heater 1” to 3”
from the ceiling (see illustration).

SAUNA ROCK PLACEMENT-SC
SAUNA CRAFT HEATERS
FILLING THE ROCK COMPARTMENT (FIGURES 10-14)
The rocks should not be stuffed into every nook and cranny. This will "choke" the heater,
trapping the heat inside and will result in nuisance tripping of the heater’s built-in hi-limit.
Placing the rocks properly improves heater operation and speeds up the heat up time.
Extra rocks are supplied. Depending on the heater model, you will use about 1/2 to 2/3. Keep
the rest for extra.
The rocks should filled as indicated below:
CWS, CWM (Figure 10): Fill center and one side chamber. Leave the other side chamber open.
Fill center and one side. Leave the other side open.
Fill 3/4 of rock tray. Leave about 4” at one side open.
CW-XR (Figure 12):
FM (Figure 13):
FM-STL (Figure 13): Fill 3/4 of rock tray. Leave about 4” at one side open.

Problem Probable Cause Remedy
Heater will not start Control wired incorrectl
y
High temperature control has tripped
Thermostat off or set below room temperature
Timer off Turn timer clockwise
No Power
Call for assistance.
Call service person.
Sauna not hot enough Temperature not set high enough Set thermostat higher- normal range is 80-90. C.
Thermostat sensor not positioned properly Relocate sensor. Should be at ceiling 3' -4 ' from heater
Thermostat miscalibrated Recalibrate or replace
Replace element
High Limit tripped Reset. (See above)
High Limit defective Replace high limit
Thermostat sensor not positioned
properly
(very common)
Relocate sensor. Should be at ceiling 3' -4 '
from heater. (If bulb is further away it will report
a lower temperature and the heater will stay on
too long. You can also try to lower temperature
setpoint on thermostat to "compensate" for the
false reading.
Thermostat broken or miscalibrated Recalibrate or replace
High Limit defective Replace high limit
Sauna too hot Sensor not properly positioned
Thermostat broken or miscalibrated Recalibrate or replace
Breaker trips frequently G.F.C.I. breaker was used Replace with standard breaker
Breaker to small for heater installed Replace with properly rated breaker
Short circuit or ground in wiring Call service person.
Note: Except where noted otherwise, reference to control refers to TPT3 mechanical control
Sauna on, but no real heat.
Elements are not glowing red. Sauna has been wired at 120 volt. (Note:two 120 volt lines does not make 240 volt.
SAUNA TROUBLE SHOOTING
Using pencil or other non-condutive material, carefully
push in "reset" button at front bottom of heater
Turn thermostat clockwise. Saunas are generally set to
between 80-90 C. (175-194. F)
Faulty magnetic contactor (applies only to
heaters 7.5 kw & larger)
Check wiring diagram carefully to ensure control
circuit is wired correctly
Too many rocks or rocks packed too
tightly, trapping heat inside.
(very common)
Leave one side of rock tray free of rocks. Rocks
should be stacked so that air can pass through.
(Public) Sauna being tampered with by
users; i.e splashing water or placing wet
towel on thermostat sensor bulb
Close sauna to public use. Run heater for 2-3 three
hours. If sauna does not trip, this suggests the
problem is user tampering.
One or more elements burned out
Call qualified service person. Using meter, confirm there
is 240 across line 1 and line 2.
High Limit trips frequently
Pilot light on. No Heat
Turn on breaker. If on, it may be faulty or installed
incorrectly. Call for service.
Reposition sensor or lower thermostat setting to
compensate.
One or more elements not
glowing red

HOW TO TAKE A SAUNA
1. Start with a brief shower using warm water and soap. Rinse thoroughly. Do not towel dry.
2 Enter the pre-heated sauna - 80°-90°C⋅(176°-194°F). Take a towel in with you to sit on. Relax
and allow your body to perspire freely in the soft dry heat. Do not throw water on the rocks in this
first session. Do not expect to begin and finish your sauna in a few minutes. Even in the extreme
heat of a sauna, it takes time for your body temperature to rise and for you to begin to perspire
freely.
3 Stay inside the sauna only as long as it feels pleasant. Go out now and then to cool off and
freshen up with a quick cool shower. How long you stay in the sauna is up to you. It depends on
your comfort level. It is not an endurance test. People often start at 5-10 minute intervals and
work up to longer periods.
Young children love saunas. Let them splash about in a tub of water on the floor or the lower
benches where it is somewhat cooler. But remember to keep an eye on them at all times
4 Re-enter the sauna. Sprinkle water on the hot rocks to bring up a little steam and increase the
humidity. This will increase the feeling of heat and assist the perspiration process. If you like add
a few drops of scented essence such as eucalyptus into the water you splash on the rocks. It will
disperse throughout the sauna.
5 Take a cold shower. Repeat the sauna/cold water cycle as often as you desire.
6 Dry yourself completely. Then sit or lie down, letting your body relax.
7 Relax, treat yourself to a cold drink and enjoy a sensation of true well-being. Don’t get dressed
until your body has cooled down and your pores have closed. Never get dressed right after your
sauna. This will only cause you to perspire
NOTE: When used for the first time, you will notice smoke coming off the heater
elements. This is normal. Leave the door open and allow the sauna to run about
30 minutes.
