no water or moisture in the stone heater, the stones shall be dry, and so shall be the
boards in the rooms. If the rooms and the heater did not dry thoroughly, it is allowed to
carry out addional stoking of the heater with a completely closed ash drawer.
IMPORTANT! The following is prohibited:
‒ allowing rewood to burn inside the heang ue;
‒ using explosive, toxic, highly ammable substances, paints, solvents, gasoline, etc., to
ignite the rewood;
‒ operang the heater at a constant excessive dra in the rebox.
IMPORTANT!
• Paral burning out of heat-resistant enamel is possible on the most thermally loaded
elements of the heater during operaon, which is not a manufacturing defect.
• The rebox metal may become slightly deformed during operaon, 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 me
aer terminaon of the heater operaon, if the room temperature drops below + 5 °С
during interrupons of the heater operaon.
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 dierenal temperature.
IMPORTANT! It is prohibited to use soluon of salt to generate steam during operaon:
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!
IMPORTANT! Carry out maintenance works on the heater and chimney only aer their
complete cooldown.
IMPORTANT! Take measures recommended for safety. Use personal protecve equipment
required for such works.
The heater and chimney shall be cleaned of soot before the commencement of the heang
season, as well as during the enre heang season at least once every three months. Cleaning
to be performed mechanically. Use special devices, tools and machine
s (brush, cleaner,
scraper, sinker, vacuum cleaner, etc.). The selecon of the necessary tools is made based
on the needs of the cleaning works. Cleaning the ue channels of the heater is carried out
through the cleanout hole after removing the cap (refer to Appendix 2): unscrew both nuts,
remove the cap. After cleaning the flue channels, install the cap, pre-clean the old sealant and
apply a new layer, twin and tighten the nuts. Soot in the chimney accumulated due to poor
cleaning, as well as incomplete combustion of fuel, can break into flames.
