19. Reconnect ignition and fl ame rectifi cation leads.
20. Reconnect gas union and tighten.
21. Refi t combustion chamber cover, secure with screws.
22. Examine seals on room sealed cover refi t cover and secure with screws.
23. Turn on gas and electricity.
24. Fire boiler and check all gas joints for soundess.
25. Check fl ame picture and all controls for correct operation.
26. Check room sealed cover for leakage.
27. Check operation of all safety cut off devices.
28. If a combustion analyser is to be used there are test points provided on the front of the room sealed cover.
The right hand grommet is for air and the left hand one is for fl ue gas. The boiler must reach operating
temperature before this test is carried out (normally 10-15 minutes). CO/CO2 ratio should not exceed 0.0080.
Immediately after servicing (0.0040 at any other time)
29. Refi t case and secure with screws.
30. Leave boiler set to customers requirements.
6.04 Flue Gas Analysis
1. The appliance should be checked visually for obvious defects.
2. After removing the jacket on the boiler there are two test point, one for fl ue gas and the other for air.
3. Open the air and fl ue gas test points;
4. Introduce the probes as far as the retainer;
5. Turn on the hot water tap;
6. Turn the domestic hot water stat to maximum;
7. Allow the boiler to reach thermal equilibrium (10 - 15 min.);
8. Take reading;
9. The CO/CO 2 ratio should be 0.0040 or below. If the reading is
above this then a full strip down service must be carried out and
the cause remedied.
10. Following a full strip down service and after reaching thermal
equilibrium the permissible reading is 0.008 or below.
N.B.: To ensure correct readings the boiler must have reached normal
operating temperature. Testing the boiler before thermal equilibrium
has been attained will give incorrect readings.
N.B.: If you have only 1 probe, measure separately air and fl ue gas,
close the test point not in use.
