Installation & Servicing

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.

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 control box fixing screw. Pull the box forward

and downward to disengage.

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.

a. 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.

b. Connect a suitable gas analyser to the sampling point on

the top RHS of the back panel. For correct boiler operation
the CO/CO

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 c.

c. Clean the main burner. Refer to Frame 51.

d. Clean the heat exchanger. Refer to Frame 52.

e.  Clean the main and pilot injectors. Refer to Frame 53.

49 SCHEDULE

f.

Remove any debris from inside the base of the casing.

g. Check that the flue terminal is unobstructed and that the flue

system is sealed correctly.

h. 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 50
to 54 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.

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.

Note.

 In order to carry out either servicing or replacement of

components, the boiler casing must  be removed. Refer to
Frame 50.

1. Open the controls pod door and release the 2 captive

screws at the bottom of the casing.  Swing the bottom of
the boiler casing out until the controls pod casing has
cleared the controls, then unhook the casing top from the
pack panel. Retain the casing in a safe place. Where the
removal of the casing is impaired by a pelmet, the
instruction in Frame 2 should be followed.

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