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 8 0 0 °C.
Recommended fuel type: hardwood with a moisture content not more than 20 % with a
maximum burning point less than 8 0 0 °C.
The moisture contained in the firewood has a significant impact on the combustion process
and the heater efficiency, hence to reduce the rate of soot formation on the walls of the
chimney and the flues of the firebox, it is necessary to use the recommended fuel types.
IMPORTANT! Different fuel types have different heat of combustion. When a large amount
of firewood with a high heat of combustion is burned, as well as when the heater is
operated at a constant excessive draft, the heater service life decreases.
IMPORTANT! The following is not recommended as fuel:
‒
coniferous, resinous tree species (spruce, fir, pine, etc.);
‒
construction and other materials containing chemicals, glue, etc.;
‒
Vegetation residues (grass, leaves, etc.).
IMPORTANT! The following is prohibited to be used as fuel:
‒
combustible materials with a high heat of combustion (coal, wood chipboard, plastic,
pellets and so on);
‒
painted or impregnated wood;
‒
waste (plastic, rubber, textiles, 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 after its complete cooldown.
• Clean the stones from dirt and dust before putting into the heater, thoroughly rinse them
with water.
• Put large stones down and small ones up.
• Choose the option which suits you the best when putting the stones, namely:
₋ put your stones loosely in order to allow for free circulation and intense convection of air,
thus ensuring maximum heating of the steam room;
₋ closely laid stones prevent convection and provide maximum protection from infrared
radiation.
IMPORTANT! It is prohibited to use halite to fill stone heaters.
