The heater takes about 100 kg of stones. They should have the qualities listed above.
The stones supplied by the manufacturer have all the necessary qualities. They're prewashed, but we recommend rinsing
off the excess dust before piling them in the heater. Pile the stones carefully without pushing them in. Follow the three
following principles in piling the stones to make sure the sauna heater operates properly and to prolong the useful life of
the heating elements.
1.
Pile the stones airily and use large enough stones (70….100 mm).
2.
Don't push the heating element tubes together, try to keep them separate.
3.
Re-pile the stones often enough to remove broken and brittle stones before they harm the heating
elements.
Depending on the use, the stones should be piled again at least after every 400th sauna bath.
Pile the largest stones in the package on the edges and on the top.
Fill in the entire space intended for stones. However, leave a 50 mm gap at the opening under the lid to allow the steam
pressure to normalize. If there are stones immediately on the mouth of the opening, the steam pressure may shoot some
of the water out of the heater as hot drops.
Small and brittle stones block the heat transfer from the heating elements. Therefore the elements may overheat, which
shortens their useful life.
The warranty does not cover damage caused by too small, brittle, poor quality or too tightly piled stones.
NOTE: Structural clay tiles are not allowed. Using structural clay tiles may cause damage to the sauna heater.
Damages caused by using structural clay tiles will not be covered by the warranty.
DO NOT USE THE HEATER WITHOUT STONES.
CONNECTION OF CONTROL CURRENT
There are two switches at the lower front of the sauna heater. The left one is the main switch, 0/I. The switch should be
in the upper position, when you want the heater to warm up.
The right hand switch is the direct connection for 200 W simmering level to be used in remote control etc.
If you connect a telephone remote control relay between the sauna heater's connectors X-X and the 200 W switch is in
the upper position, you can remotely switch on the 300 W simmering level by telephone. The 100 W simmering level
switches on automatically.
For example, if you phone in the 300 W simmering level on Thursday, the sauna will be warm on Friday, when you
arrive to your cabin. The 300 W heating time is about 30 hours.
Note! There should be another switch connected in parallel with the remote control relay for use in the location.
8 kW: Saunatonttu's simmering level is 260W + 100W = 360W, so the heating takes 24 hours.
HEATING THE SAUNA HEATER TO STANDBY MODE
Ever Ready heaters can be preheated to a standby mode (with lid closed) by switching on the 0.3 kW simmering level
for about 30 hours. For faster preheating, you can also switch on the actual full sauna bathing power:
Saunatonttu 3
2.0 kW
Heats up in ~4-6 h
Saunatonttu 3 and 4
3.4 kW
Heats up in ~3-6 h
Saunatonttu 4
4.8 kW
Heats up in ~2-5 h
Saunatonttu 6
6.4 kW
Heats up in ~2-5 h
Saunatonttu 8
8.0 kW
Heats up in ~2-4 h
The above values are approximate.
NOTE:
Never heat up the sauna heater without stones. Damages caused by heating an empty heater will
not be covered by the warranty.
