Installation and Operating Instructions Klapi
The draught control plate located under the
sweeping door can be used to either increase or
reduce draught.
A high chimney or other similar factors may
generate excessive draught, in which case the
draught control plate can be used to reduce the
opening.
Similarly, if the sauna is located in a hollow, for
example, better draught may be required, in
which case the opening of the draught control
plate should be made larger.
After the adjustment, make sure that the draught
control plate is tightened securely so that it
cannot move as a result of thermal expansion.

Adjusting the draught
When you begin building a fire in the heater,
you may want to keep the ash pan slightly
ajar to achieve good draught, which improves
combustion.
During bathing and when the sauna room has
heated sufficiently, the ash pan can be closed.
Excessive draught will heat the body of the heater
all over until red-hot, which will considerably
reduce the service life of the heater.
If you leave
the ash pan open, smoke may enter the sauna.
If necessary, add more wood in the firebox when
the embers start to fade. Use logs with a diameter
of about 10–15 cm.
To maintain suitable heat for bathing, adding a
couple of logs at a time is sufficient.
Prolonged intense heating may cause a fire
hazard!
As a rule of thumb, a temperature over 100 °C in
the sauna is excessive.
Follow the wood quantities given in the
instructions. Let the heater, flue and sauna cool
down, when necessary.
Checking the sweeping doors
Before starting to use the heater, ensure that the
sweeping doors on the sides are in the correct
position.
The braces of the sweeping doors must be
aligned with the direction of draught.
Water thrown on heater
Use clean drinking water to generate steam.
Make sure the quality of the water is high, as salty water or water containing lime, iron or humus may
corrode the heater fast! Using seawater corrodes the heater in an instant, so seawater or any other
saltwater may not be used.
