humming of the heater, too erratic flame) 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.
7.
Add firewood into the firebox as it is consumed. Carry out stoking until smoke and
odor disappear (for one hour approximately), then let the heater cool dowb without
removing the coals.
IMPORTANT! During the first heating up avoid the chance of mechanical impact on the
paint coating of the heater (do not put the stones into the stone heater, do not rub the
surface, do not pour water).
IMPORTANT! Do not heat up the heater at constant excessive draft which can lead to
heating of the firebox red hot, as this will reduce its service life. Control the draft by
adjusting the ash drawer gap.
IMPORTANT! Install the heater on the place of permanent operation only after
complete cooldown.
IMPORTANT! In case a water tank is installed, it shall be cleaned thoroughly before
use. The water tank shall be filled before heating.
2.4. Combustion material
Approved fuel types: dry wood, fuel briquettes without artificial binder resins with a
maximum burning point less than 800 °C.
Recommended fuel types: hardwood with a moisture content not more than 20 % with a
maximum burning point less than 800 °C.
The moisture contained in the rewood has a signicant impact on the combuson process
and the heater eciency, hence to reduce the rate of soot formaon on the walls of the
chimney and the ues of the rebox, it is necessary to use the recommended fuel types.
IMPORTANT! Dierent fuel types have dierent heat of combuson. When a large amount
of rewood with a high heat of combuson is burned, as well as when the heater is
operated at a constant excessive dra, the heater service life decreases.
IMPORTANT! The following is not recommended as fuel:
‒ coniferous, resinous tree species (spruce, r, pine, etc.);
‒ construcon and other materials containing chemicals, glue, etc.;
‒ Vegetaon residues (grass, leaves, etc.).
IMPORTANT! The following is prohibited to be used as fuel:
‒ combusble materials with a high heat of combuson (coal, wood chipboard, plasc,
pellets and so on);
‒ painted or impregnated wood;
‒ waste (plasc, rubber, texles, leather, etc.).
2.5. Stones for stone heater
The permissible stone sizes are given in Table 1.
Only the stones intended for sauna shall be used as heater stones.
IMPORTANT! Put the stones into the heater only aer its complete cooldown.
• Clean the stones from dirt and dust before pung into the heater, thoroughly rinse them
with water.
• Put large stones down and small ones up.
• Choose the opon which suits you the best when pung the stones into the outer stone
heater, namely:
₋ put your stones loosely in order to allow for free circulaon and intense convecon of air,
