14. CLEANING AND MAINTENANCE
Each time before loading the fuel, clean the grate using a small shovel by opening the grate holder or through
open firebox door. Remove the ashes from the ash pan at least once a day and remove the larger residues by
opening the ash pan door and grate holder. All surfaces of the stove that are in contact with flue gases must be
regularly maintained and cleaned using a small shovel. Clean heating areas guarantee cost-effective stove
operation. It is recommended to clean the stove once a month or more often, if necessary.
Do not clean enameled surfaces and stove frame using wire brush or wire sponge because it could damage the
enamel and safety lining, but use wet cloth, cleaning agents and mild detergent instead. Clean the oven after
each use while still hot. After cleaning, leave the oven door open for a few minutes to prevent bad odors the next
time you heat the oven.
Clean the cooktop occasionally using fine sandpaper, and in the event of longer breaks, apply acid-free oil on the
cooktop (vegetable oil). Remove burnt material from the cooktop with a spatula, knife or treat it with graphite,
ashes from the ash pan or oil.
It is prohibited to cool down the stove by making an artificial draft or by using water to cool down the firebox.
15. CONSERVING THE STOVE
At the end of the heating season, clean the stove from ashes and soot. Discharge the water only if any repairs
need to be carried out on the installation. If the system is not used during heating season, poor a certain amount
of antifreeze liquid into the system or discharge the water to prevent freezing.
16. TROUBLESHOOTING
Table 3
No.
Problem
Possible cause
Repair
1
Water pressure in the
system dropping
slowly.
Installation is not
sealed.
Check whether all welded connections, threaded
connections, unions etc. are sealed.
2
Radiators are cold at
system’s maximum
height and a low
sound is heard.
Air in the system and
small pressure in the
system.
Increase system pressure and bleed the air from
the system and radiators.
3
Radiators are not
heated along their
entire length.
Air in the radiators.
Bleed the air from the radiators using release
valve.
4
Safety valve is not
discharging water
from the system and
the pressure is below
3 (2.5) bar.
Faulty safety valve.
Replace safety valve.
5
Pressure in the
system is over 3 (2.5)
bar and safety valve
is not discharging
water from the
system.
Faulty safety valve.
Replace safety valve.
6
Sudden water
temperature rise in
the system.
Air in the system.
Bleed the air from the radiators.
Valves toward
radiators are shut.
Open all valves in the heating system and enable
normal water circulation in the system.
Circulation pump
failure.
Repair or replace the circulation pump to enable
heating system operation.
Power outage.
Open all valves that reduced the heating system
and first of all, the by-pass valve.
Stop making fire or make less fire and carefully
monitor the system so that the water temperature
does not exceed 90
C when the power is back
on.
