OPERATION AND REGULAR MAINTENANCE
Fill the furnace and heating installation with water and release air from it. Before commencing operation,
check if the furnace and installation are functioning properly and if all the latches, vents, measure and
regulation instruments are correctly set.
Put the circulating pump into operation when using the circulating pump heating system. If the chimney is
new, the furnace should not constantly be under full load until the chimney is completely dry.
IMPORTANT!
Before and during operation follow the instructions provided by the furnace manufacturer:
-
After checking the proper functioning of the furnace and installation, fully open the door for kindling
and ash pan (Fig. 8, pos. 4), open the fixed grate (Fig. 8, pos. 1), disperse paper and wood kindling over
the grate (Fig. 8, pos. 2), ignite it and wait for the fuel to catch fire.
-
Add a small amount of coal and wood and allow flaring. Close the kindling door (Fig. 1, pos. 9), and set
the airflow regulator (thermostat) to flow position 7.
-
Fill the furnace with fuel up to one third of the firebox area’s height
and allow it to stir up again until
the upper layer of coke, coal or wood catches fire. Set the desired temperature on the thermostat.
-
Fill the furnace with fuel up to the lower ledge of the filling door (Fig. 1, pos. 3). If the fuel emits
several gases, the use of the bottom of the fuel layer is recommended as well as frequent refilling.
When the fuel emits larger amounts of swelling gases, slightly open the filling door, the ash pan door
and the hob lid to enable releasing of the accumulated gases and to prevent flaming.
-
Additionally fill (refill) the furnace once the fuel has burnt out up to one fourth or one third of the
firebox area’s height. Before refilling, use the fire hook for stoking
(Fig. 10) through the fixed grate or
the furnace grate (Fig. 8, pos. 2), and then shake through the grate shaker handle (Fig. 1, pos. 8) by
moving the handle forward and back. Refill with fuel after shaking.
-
In order to regulate constant combustion when using coke as fuel, set the thermostat to positions 6 to
9 and allow fully loaded furnace to burn for half an hour, and then set the thermostat to positions 4–5.
Heating instructions are only guidelines and could vary depending on the installation type, chimney
'
s
draught
strength, and type of fuel and outside air temperature.
IMPORTANT:
Regularly check the level of furnace sealing (boiler kit and asbestos-free materials). Special attention should
be paid to the water amount in the installation, since the improper amount would disrupt the heating system.
In case of such disruptions, the installation should always be filled, but only when the boiler cools down.
