Boiler’s emergency
overheating
Absence
of
heat
consumption
or
incorrect adjustment of
the
operating
parameters
of
the
boiler
or
poor
operation
of
the
heating system
It is necessary to check the
correct operation process of
the heating installation and
eventually
appropriate
adjustment of the operating
parameters of the boiler
and/or control valves of the
heating system – this should
be performed by authorized
technician. After the boiler is
cooled down to ambient
temperature and the reason
for boiler overheating is
serviced/solved
out,
the
protective
cap
of
the
emergency
overheating
thermostat
should
be
unscrewed, its rod should be
pressed until the thermostat
is reset and it’s cap should be
screwed back. The main
“POWER” switch is turned
OFF and back ON afterwards
and the boiler should be
started.
Low quality wood logs
(in most cases the
moisture content is
higher than 20%)
Fuel
replacement
is
recommended,
use
wood
logs, which have properties,
covering the requirements
4.
The flame looks
“opaque”
and
smoke is observed
at the exit of the
chimney
Inappropriate
operating
parameters
adjustment
It is necessary to perform
adjustment of the operating
parameters of the boiler and
achieve efficient combustion
process – see 5.3.7.
5.
Presence
of
unburned fuel in the
combustion
chamber
Ineffective
fuel
combustion process
It is necessary to perform
adjustment of the air flow
rate – see 5.3.7
6.
High temperature of
the flue gases (if
flue
gas
thermometer
is
mounted)
The heat exchanging
surfaces of the boiler
are deposited with ash,
presenting
heat
resistive layer, thus
It is necessary to clean
thoroughly
the
heat
exchanger surfaces of the
boiler;
