52 SERVICING SCHEDULE

To ensure the continued safe and efficient operation of the appliance it is recommended that it is checked at regular intervals and serviced as necessary.

The frequency of servicing will depend upon the installation condition and usage, but should be carried out at least annually. It is the law that any service work must be carried out by CORGI registered installer. In IE service work must be carried out by a Competent Person.

As the installer you may wish to undertake the service contract yourself or alternatively offer to the customer the benefits of the Ideal Care Scheme, details of which are outlined in the household pack supplied with this boiler.

1.Light the boiler and carry out a pre-service check, noting any operational faults. Operate the boiler for at least 20 minutes. Check the gas consumption.

2.Connect a suitable gas analyser to the sampling point on the top RHS of the back panel. For correct boiler operation the CO/CO2 content of the flue gas should not be greater than 0.004 ratio. If this is the case and the gas input is at least 90% of the nominal, then no further action need be taken. If not, proceed to paragraph 3.

3.Clean the main burner. Refer to Frame 56.

4.Clean the heat exchanger. Refer to Frame 55.

5.Clean the main and pilot injectors. Refer to Frame 56.

6Clean the recuperator. Refer to Frame 57.

8.Remove any debris from inside the base of the casing.

9.Check that the flue terminal is unobstructed and that the flue system is sealed correctly.

10.If the appliance has been installed in a compartment, check that the ventilation areas are clear.

The servicing procedures are covered more fully in Frames 54 to 60 and must be carried out in sequence.

WARNING.

Disconnect the electrical supply and turn off gas supply.

IMPORTANT. After completing the servicing or exchange of components always test for gas soundness and carry out functional checks as appropriate. Refer to Frame 48, item 18 for gas adjustment sealing.

When work is complete the casing MUST be correctly refitted, ensuring that a good seal is made.

The boiler must NOT be operated if the casing is not fitted.

11.Complete the service section of the Benchmark Commissioning Checklist.

53 BOILER FRONT PANEL REMOVAL

1.Open the controls pod door and release the 2 captive screws at the bottom of the casing, then unhook the casing front panel from the back panel and remove. Retain the front panel in a safe place.

2.Isolate the gas supply at the service cock fitted to the boiler.

54 BURNER AND AIR BOX REMOVAL

1.Remove the screw retaining the front burner support strap to the combustion chamber. Remove the M5 pozi situated at the LH bottom rear of the burner and pull the burner downwards to disengage the retention tab. Remove the burner to a safe place for inspection and cleaning.

2.Remove the 2 control box fixing screws. Swing the box downwards to disengage.

3.Pull the HT lead connection off the printed circuit board and pull the lead upwards through the bottom panel grommet.

4.Remove the 4 screws retaining the air box/pilot assembly to the vertical manifold and carefully remove the assembly.

5.On re-fitting the air box assembly, remove the old gasket from the manifold and ensure the new gasket is located correctly. Check that the joint is made gas tight. Ideal Boilers recommend the air box fixing screws be replaced with a torque of 4.0Nm in the number order shown on the diagram below and be repeated to ensure even clamping.
