Troubleshooting
The boiler water temperature does not rise to the desired level
Make sure that the burner is adjusted
properly.
Make sure that fuel is supplied from the
adaptor to the burner.
Make sure that thermal valve eventually
connected to hot water supply coil is
closed.
Make sure that mixture valve is function-
ing correctly.
The boiler boils and sputters
Make sure that water quantity is sufficient
in the system and pressure in the system is
0.8-1.5 bar.
If there is no water in the sys-
tem immediately stop heating by switch-
ing off the burner. Do not add water to the
boiler at once, let it cool down by blowing
it with cold water. When the boiler is
cooled down, the system can be filled
with water and heating process can be
started again.
Check that the pump and the mixing valve
are working and check the circulation
through the pump and piping. The air pre-
sent in the system can inhibit water circu-
lation.
The flue gas temperature is too high
Flue gas temperature shall not exceed
350 ºC as stacks do not tolerate high
temperatures.
Clean the boiler.
Soot, ash and tar contaminate fired surfac-
es of the boiler and act as heat insulation.
Make sure that turbulent plates of convec-
tion part flue gases are in the right place
and are integral.
Warranty
The warranty is confirmed to be two years for the boiler and one year for the components. The war-
ranty is effective provided that installation, start-up, and maintenance are done or approved by an
