CONNECTING TO THE BOILEr
•
The device should be placed a in way, so there will be enough space for cleaning, removing the soot from the burner,
the boiler and the draught pipes.
•
The burner must be installed in the boiler outlet with the relevant isolation. It must be joined up with nuts.
Under one of the nuts there must be put a SPECIAL T-FIGURE TIN DETAIL which is for pushing the limit switch,
INFORMING THAT THE BURNER IS INSTALLED. It is absolutely forbidden the eliminating of this protection since it is
directly connected to the fire safety.
•
The contact between the burner and the boiler should be well tight in order to prevent gas leaks in the service room.
•
When installing the system, it should be in optimal horizontal position. The hose should be straight and the connections
should be tight.
CONNECTING TO THE ELECTrICAL NETWOrK
•
After connecting the burner to the boiler, the technician should connect the burner to the electrical network as shown on
the enclosed connection scheme.
ATTENTION
•
The connection must be done by a qualified electrical technician and there must be paid high attention to the safety
grounding of the device.
The connecting is shown in the present manual and also with special stickers to the main cable.
Connecting:
- A four-wired cable which is connected to the boiler, goes out of the burner.
The meanings of the conductors are as they follow:
-
black
- phase (220V, 50Hz) - the black conductor connects to a terminal from the boiler, which when the main switch is
on always has 220V phase (if the emergency thermostat is not on). This is the power supply of the burner.
-
brown
- (220V, 50Hz) from thermostat (start burner) - the brown conductor connects to a terminal, connected with the
boiler’s thermostat. It gives a phase (with the same polarity as the power supply ) for starting the burner, i.e. when a
voltage shows on this conductor, the burner perceives it as a start-burning signal.
When the set temperature is reached, the thermostat turns off, the pressure goes off and the burner stops running.
-
blue - N
- neutral - the blue conductor must be connected to the neutral conductor.
-
yellow/green
- PE - protective earth - the yellow-green conductor must be connected to the grounding.
