11. COMMISIONING
h
11. Let the boiler run for a couple of minutes to get rid of
air in the gas pipe.
12. Set the correct burner pressure.
13. Optimal combustion efficiency can be obtained by
adjusting the plate on the rear of the economiser so
that a CO
2
of 7-8% is obtained at a minimum return
water temperature of 60
°
C.
14. Check that the thermostats are locked in position.
15. Check for flame protection by starting the boiler with
ionisation probe disconnected.
16. Check the operation of the air-pressure switch.
11.3 Switch off the boiler
1. Switch off the electric supply.
2. Turn off the gas cock.

11.2 Commissioning
1. Check gas connections.
2. Check electrical supply (L/N and earth).
The control box operates on a neutral/phase
supply.
3. Check water connections and release the air out of
the ECO and boiler. Fill the syphon with water.
4. Switch on circulation pump and check rotation direc-
tion.
5. Open main gas cock (release air in gas pipe work).
6. Switch on electrical supply.
7. Check rotation direction of the flue fan.
8. Set the control thermostat at about 85
°
C.
9. Adjust the sliding air inlet (see table).
10. After a waiting time of about 43 seconds you will get
ignition. At a minimum ionisation current of 7
µ
A the
safety gas valve will open and the pilot gas valve will
close after about 15 seconds. The boiler is on.
