birch bark, wood chips and other natural materials, or using paper or throwaway
newspapers.
4.
Close the door.
5.
Partly close the ash drawer
after heating up of the chimney and development of stable
draft (usually after burning of the first load of firewood), leaving a gap within 10 mm.
It is necessary to constantly ensure sufficient draft, while avoiding the development of
excessive one, that leads to heating of the firebox red hot, which significantly reduces
the heater service life. Control the draft by adjusting the ash drawer gap.
6.
When additional firewood is required
, open the door smoothly, without jerks. Load the
firewood and close the door. Adjust the draft. A couple of logs are enough to maintain
the optimum temperature for steam bathing. Bear in mind, that excessive heating (for
example, several full loads in a row) leads to overheating and shortens the heater and
chimney service life, and can also cause a fire.
7.
The heater operation may be terminated
after the entire load of firewood burns up.
IMPORTANT! The following is prohibited:
‒
allowing firewood to burn inside the heating flue;
‒
using explosive, toxic, highly flammable substances, paints, solvents, gasoline, etc., to
ignite the firewood;
‒
operating the heater at a constant excessive draft in the firebox.
IMPORTANT!
•
Partial burning out of heat-resistant enamel is possible on the most thermally loaded
elements of the heater during operation, which is not a manufacturing defect.
•
The firebox metal may become slightly deformed during operation, which is not a
manufacturing defect provided the integrity of weld joints is preserved.
•
In case there is a hot water tank, water shall be drained from the tank every time
after termination of the heater operation, if the room temperature drops below + 5 °С
during interruptions of the heater operation.
2.7. Water in the sauna
The water poured onto the stones shall be clean tap water. Ensure the water quality. Water
with a high content of iron, salt, humus, or lime can lead to early corrosion of the heater
elements. For example, seawater will lead to rapid corrosion of the stone heater. The tap
water quality shall meet the following requirements:
‒
humus content <12 mg/liter;
‒
iron content <0.2 mg/liter;
‒
calcium content <100 mg/liter;
‒
manganese content <0.05 mg/liter.
IMPORTANT! Water shall only be poured onto the stones. If water is poured on heated
steel surfaces, they can be deformed due to high differential temperature.
IMPORTANT! It is prohibited to use solution of salt to generate steam during operation:
pouring it into the closed stone heater (if available), pouring it onto outer stone heater
and the heater metal.
2.8. Maintenance
Routine maintenance
of the chimney, heater and its parts is the key to their efficient and
safe operation, your safety and safety of your close ones!
