Main gas connection
The connection is made using gas pipes with Rp 1/2 ISO 7 threading. Torque: 25 Nm.
If, alternatively, flanges (available on request) are used, first screw the pipes onto the
flanges and then the flanges to the valve. Recommended torque for the flange fixing
screws: 3 Nm.
Connection to the pilot burner
Pipes with Ø 4 mm, Ø 6 mm or Ø 1/4 can be used. Use a nut and olive of appropriate
dimensions. Tighten the nut to 7 Nm torque.
Connection to the combustion chamber
Pressure regulator / combustion chamber compensation is possible when the latter is
pressurized (see figure).
Use the special SIT hose connectors for this purpose. Torque: 1 Nm.
Electrical connections
Use the special connectors for connection to the thermopile and to the thermostat.
Make the connections in accordance with the plan below and in accordance with the rules
for the appliance.
The electrical safety cut-off devices (for example, the flame failure device, limit
thermostat, and the like) must cut off the power supply to the thermoelectric circuit of the
safety magnet unit.
Caution:
after making the connections, check gas tightness.
