3.1. GENERAL
The Kastor sauna heater is ready for use once the stones are laid and the hot water tank, if any, filled.
However, pre-burn the stove when it is still outdoors. Make sure that the secondary air deflector
is in position as explained in section 3.2. Before laying the stones burn one or more fire boxfuls of
logs with the window open to remove any remaining protective agents and harden the coating.
To avoid damage to brickwork chimneys, do not instantly use the heater at full heat in cold
weather.
The service life of the heater is greatly reduced if exposed to salt water. Please note that water in
wells near the sea may contain salts.
The service life of the heater is affected by other factors as well, such as the steam room capacity,
frequency of use, type of fuel, operation in violation of the instructions, and general care. All
Kastor heaters have been carefully designed and tested.
Experience shows that if the heater
is damaged in use prematurely (e.g. walls are torn or burnt through, the top is burnt, etc.),
the heater has been used contrary to instructions. Kastor accepts no liability for such
damage.
If the heater is continuously red hot, its service life is shortened.
Please note that the extended fire door section of a heater with a hot water tank is not intended as a fire box –
logs must be burnt in the rear inside the actual fire box. Failure to do so will damage the heater.
3.2. SECONDARY AIR DEFLECTOR
There is a detachable secondary air deflector in the rear of the fire box (Figs. 2A and 2 B). The
heater may not be used without the deflector! If the deflector is worn in use (warped or
otherwise damaged), it must be replaced. Install the deflector as shown in Figs. 2 A and 2 B in
the rear of the fire box so that its support rests on the fire grate bracket. After this, always replace
the fire grate. Check the deflector regularly.
3.3. FUELS
For fuel, always use natural untreated wood , preferably solid birch or alder cut to a length of one-
third of a meter (12”). Wet or rotten wood does not produce much heat. Never burn
impregnated wood, wood containing nails, particle boards, plastic, plastic-coated
cardboard or paper, or liquid flammable fuels
– not even when starting the fire (to avoid
damage to the fire grate). Do not fill the fire box with finely chopped fuel, such as chips and
small splinters because of their instantaneous high thermal energy. Firewood may not be stored
in the immediate vicinity of the fire. (Observe safety distances!). Bring inside only the amount of
wood that can be used immediately.
3.4. INSTRUCTIONS FOR HOT WATER TANK
The heater may be provided with a hot water tank depending on the model. The tank may not be
used for any other purpose than heating water. Please note the following:
x
The water tank must always be at least half-full when there is a fire in the heater.
x
Make sure that the tap is properly closed.
x
Freezing of the water may break the tank. Empty the water tank after use.
x
The tap gets hot when there is a fire in the heater.
3.5. ADJUSTMENT OF DRAFT AND HEATING POWER
The sauna heater is designed to operate at a chimney negative pressure of about 10–20 Pa. This level
is often exceeded, if the chimney is very high. Typical indications of excessive height include the
following:
x
Combustion cannot be regulated with the ash pit (flames extend into the connecting pipe, possibly
even into the chimney).
x
The noise made by burning is strong and the flames viewed through the glass door appear to extend
upwards with great intensity.
x
The sauna and/or stones fail to get hot in less than 1 hour (even if the heater is of the right size).
Pull the flue damper and ash pit out before lighting the fire. Once the fire is burning well, adjust
the inlet air supply by opening it by 0.5 to 2 cm (1/4-7/8”) according to draft. Basic draft can also
be adjusted with the damper. Never close the flue damper when the fire is going –
beware of
carbon monoxide poisoning!
