Electrical installation
Electrical connection
The electrical installation must be carried out
according to existing rules under the supervi-
sion of a qualified electrician.
The burner must be preceded by an all-pole main breaker.
The design depends on which boiler the burner is installed
on, whether the boiler has existing electrical equipment and
whether the burner is to control the boiler temperature.
Connections to burner
Feed auger
Temperature sensor
Power cable
Connector - 230 V~ power cable

a
c
The septuple-pole plug, a, is inserted in the socket, b, located
on the burner until the catch on the pushbutton, c, engages
and locks the plug in place.
For disconnection, the power to the burner must be switched
off first. Then press the pushbutton while pulling the plug out
of the socket.
N:
Neutral conductor.
: Earth conductor.
L1: Black, supply via overheating protection.
B4: Brown, connected to the boiler thermostat.
S3: Grey, alarm signal, 230 V~, from burner, max. load 1 A.
T1, T2: To any safety switch on the combustion chamber
hatch.
Alarm
In the event of an alarm, the burner generates a 230 V~
signal. The signal can be used for a visual/acoustic
presentation. If the function is not used, the cable end
must be insulated.
Hatch safety switch
A hatch switch must be installed if the combustion chamber
hatch can be opened without tools.
Safety can also be guaranteed if the supply hose is made
so short that it has to be detached before the hatch can be
opened and the burner’s connection cable is attached in such
a way that it has to be disconnected from the burner to allow
the hatch to be opened.
The jumper, T1 - T2, in the power cable’s contact part must
be removed when a hatch switch is connected.
Boiler temperature control via the burner
The boiler temperature sensor (accessory) is connected to
a contact on the burner.
It is advantageous to have the burner control the boiler
temperature if hot service water is heated in a heat
exchanger.
The temperature sensor should preferably be placed in
an immersion pocket high up on the boiler. If there is no
immersion pocket, the sensor is glued to the body of the boiler
with epoxy glue. The sensor must have good thermal contact.
In an exchanger boiler, the sensor is placed so that it senses
the exchanger’s return flow, but not on the return pipe.
When the burner is to control the boiler
temperature, the phase supply and control
phase must be preceded by overheating
protection.
