DETECTION AND FIXING OF ERRORS/MALFUNCTIONS
Error Name Error Description Fixing Applications
Ignition does not occur Burner failure
Please follow the burner
manufacturer
Dark smoke coming out of chimney
Low air surplus coefficient, Low
supply voltage
Check fresh air coming into boiler
room or air setting of burner. Voltage
drop results in decrease of engine
speed, low fuel air mixture.
Knocking in water section of boiler
Air in installation. Installation and
assembly error
Drain the air. Check connections
as per installation assembly circuit
diagram.
Overheating in boiler water
Circulation pump failure Thermostat
failure
Please check whether there is
reverse turning in circulation pump.
Check whether the boiler thermostat
is working.
Failure in increasing boiler exit
water temperature
High water speed Selection of
burner unsuitable to boiler capacity
If circulation pump is speed-
adjusted, speed should be reduced,
if it is single-speed, by reducing
valve, tuning should be made or
Pump should be replaced with an
appropriate pump.
Make your burner checked by
authorized service.
Water accumulation or leakage in
smoke chest
Condensation of water vapor in
flue gas
Failure in operating boiler in low
temperature, failure in reducing
flue gas temperature under 70°C at
boiler exit.
3 or 4-way valve should be used,
thermostat settings of boiler should
be high. The condensed water must
be drained with a connection from
the lowest elevation of smoke chest.
Condensation drain may have
clogged.
Paint cover burning, heat increase,
refractory concrete and turbulator
deformation
Wrong burner selection and higher
setting
Burner change, renovation to
suitable conduit dimension and
burner setting are necessary.
Increase in flue gas temperature
Operating without turbulator or
missing turbulators, wrong burner
setting and selection
It may be required to install
turbulator and eliminate
deficiencies, carry out setting
of burner normally and procure
suitable burner.
If water continuously decreases in
the boiler
Mechanical / Installation failure
1. Possible leakage in installation.
Check the installation.
2. If water is coming from inside the
boiler, there may be leakage in
pipe or body.
3. Expansion tank might be low
on air.
