COMMISSIONING

Note: Commissioning must only be carried out by a
qualified engineer with the relevant training and certifica-
tion i.e. Acops - Corgi. A commissioning data sheet /
boiler logbook must be completed on site for issue to
owner.
1. Check the gas connections.
2. Check the electrical supply (L/N and earth).
3. Check the water connections and whether the instal-
lation is full and under system pressure.
4. Switch on the circulation pump and check the rota-
tion direction.
5. Open the main gas cock (purge gas pipeline).
6. Switch on the electrical supply.
7. Set both the thermostats to about 85°C.
8. If a control system is built in, put the selector switch-
on manual operation.

9. Switch on the boiler.
- If a valve leakage control is installed the following
will take place:
A membrane pump will create overpressure
between safety valves VA1 & VA2, which are
inside the multibloc gas valve. When, within 27
sec, an overpressure of 30 mbar (compared to the
inlet pressure) is reached, the electric supply is
released to the control box.
10. After a waiting time of about 13 seconds the ignition
starts. The magnetic valve MK opens and ignition
burner lights. At a minimum ionisation current of 3
µA the ignition stops. After 5 seconds the main gas
valves VA1 en VA2 will open. The boiler runs.
11. Let the boiler run for a couple of minutes on high fire
to clear any air still in the gas pipe.
