11. SECONDARY AND TERTIARY AIR REGULATORS
Secondary air regulator is placed in the firebox door (Fig. 1, Item 8 and Fig. 13). It controls additional lighting
of fire and burning unburned flue gases. It is opened and closed manually using the knob on the firebox door.
Leave the secondary air regulator open when the fire in the stove is lit.
Tertiary air regulator (Fig. 1, Item 30) is located behind the tertiary air regulator cover (Fig. 1, Item 27). It
controls additional lighting of fire and burning unburned flue gases. It is opened and closed manually using the
tertiary air regulator knob (Fig. 1, Item 26).
Leave the tertiary air regulator closed when burning wood and open it when burning coal.
12. COOKING, BAKING AND FRYING
During heating season, the stove is used mainly for heating. For faster baking, cooking and frying, use only dry
firewood.
The damper used for starting the fire must be closed and power regulator must be open. After you finish baking,
cooking or frying, place the power regulator in desired position.
While baking, increase the temperature of the water in the system to at least 60
°
C and, if necessary, close some
of the radiators during baking and adjust the oven temperature to the food being baked.
NOTE: If necessary, rotate the pan during baking.
13. FUEL
Fuel can be stored in the fuel box (Fig. 14). The fuel box is moved on guides. If you want to take the fuel box
out of the stove, you must lift it to remove it from the guides.
Use the fuel specified in Table 2 to ensure the nominal heating capacity of the boiler at chimney draft of 20 Pa.
Do not burn coal dust, sawdust or waste that generates large quantities of smoke!
