The preferable option for heating up is outdoors, away from combustible surfaces and mate-
rials, in compliance with fire safety measures and safe work practices.
Install a portion of chimney stacks vertically (about 2 meters), load 3-4 logs into the heater
firebox and start up a fire. Slightly open the ash drawer to ensure sufficient draft (adjust the
gap to be within 50 mm). Once the firewood begins to burn and stable draft develops, partly
close the ash drawer (adjust the gap to be within 10 mm).
Add firewood into the firebox as it is consumed. Continue heating up until smoke and odor
disappear.
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 com-
plete 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.
Recommended fuel types:
hardwood with a moisture content not more than 25%.
The moisture contained in the firewood has a significant impact on the combustion pro-
cess 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 oper-
ated 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. Use the stone included
into the contents of delivery.
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.
