Loose knobs or
some screw on
the solid fuel
Tighten knobs and screws
11 Sounds in the pump
The pressure at
the pump suction
part is to low
Increase system pressure or check the expansion vessel.
12
The
solid
fuel
overheats, loud noise
(cracking) is heard in
the boiler of the solid
fuel.
Electricity outage
has occurred, the
circulation pump
does not work
and the boiler of
the
solid
fuel
overheats. There
is a danger of
boiler rupture.
To avoid this occurrence, it is best to have backup battery power supply
of the circulation pump with an inverter.
Installation of a thermal exhaust valve (Fig. 7, pos. 13) is required as
additional security against solid fuel overheating.
If you do not have backup supply of the circulation pump or a thermal
exhaust valve installed, then you should open the bypass valve connected
in parallel with the circulation pump on the pipeline system and remove
embers from the solid fuel.
13
Cooling thermal fuse
is activated (thermo
valve) because
water temperature
increased over 95
C
due to:
- loss of
electricity
This is proper and do not touch anything. When the system is cold,
thermal valve will be closed.
After that, check the pressure in the installation and fill the system to the
required.
- open ashtray
door and no
regulated
combustion
Close the ashtray door and through the knob on the cover of the ashtray
door and thermostat, reduce the water temperature in the system.
- the grate is in
lower position
and small number
of radiators are
switched on
Transfer the grate to upper position or switch on some other radiator.
Keep the ashtray door closed.

Insert combined valve or switch off some radiator from the heating
system
15

Switch of some radiators
Little heating

Increase the quantity of heating material in the firebox
16
Fire does not burn
regularly
Weak flue draft
Make a new flue or repair the old one
Flue pipe
connections do
not seal.
The doors on the
solid fuel and the
flue do not seal.
The flue draws
“false air”.
Seal all connecting spots so that “false air” would not occur
17
There is not enough
heat in baking,
cooking
The thermostat is
set to a lower
temperature
Increase water temperature through a thermostat or shortly open the
ashtray door
18
There is too much heat
in baking, cooking
The thermostat is
set to a high
temperature
Reduce water temperature through the thermostat or stoke moderately
19
The boiler-solid fuel
releases smoke during
initial startup
Combustion and
heating of the
solid fuel and flue
It is normal for the solid fuel to release some smoke during initial startup,
and this stops after some time.
20
The boiler-solid fuel
releases smoke during
regular use
Uncleaned flue,
flue pipes and
solid fuel
Clean the internal part of the flue, the flue pipe and solid fuel.
