Warning
Ensure that the boiler is switched off.
Do not commission the boiler if the type of gas supplied does
not match the gas types approved for the boiler.
1. Open the main gas valve.
2. Remove the boiler's front panel.
3. Check the gas inlet pressure at the measuring point C on the gas
valve unit.
The gas pressure that was measured at the measuring point C must
fall within the stated gas inlet pressure limits.

4. Vent the gas supply pipe by unscrewing the measuring point on the
gas valve unit.
5. Tighten the pressure socket again when the pipe has been fully
vented.
6. Check all connections for gas tightness. The maximum allowable test
pressure is 60 mbar (0.006 MPa).
1. Check for the presence of the recommended circuit breaker.
2. Check the electrical connection to the mains.
3. Check the connection of the sensors.
4. Check the position of the sensors. Respect the distance of the
sensors according to the power.
5. Check the connection of the circulating pump(s).
6. Check the connection of the optional equipment.
7. Check the length of the cables and that they are firmly secured in the
cable clamps.
1. Check the siphon, which must be completely filled with water.
2. Check that there are no leaks on the boiler's hydraulic connections.
3. Check the pressure in the expansion vessel before filling the system.
