16. Clean heat exchanger with a soft brush.
17. Re-assemble baffl e, fl ue hood and fan assembly, secure with screws previously removed.
18. Refi t burner assembly and burner rail.
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 domestic water fl ow rate and temperature is within specifi cations.
28. Check operation of all safety cut off devices.
29. 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 0.0040.
Immediately after servicing (0.0080 at any other time)
30. Refi t case and secure with screws.
31. 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/CO2 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.
