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 a registered installer.
As the installer you may wish to undertake the service
contract yourself or, alternatively, to the customer the
benefits of the Ideal Care scheme, details of which are
outlined in the Householder pack supplied with this
boiler.
Note.
Some aluminium oxide build-up on the heat exchanger
fins is quite usual with this type of condensing boiler.
Though removal is recommended annually, the heat
exchanger must be inspected and cleaned after a
maximum of 2 years operation.
53 SAFETY
IMPORTANT.
Always turn OFF the gas supply at the gas service cock,
and switch OFF and disconnect the electricity supply to the
appliances before servicing.
WARNING.
After completing the servicing or exchange of components
always:
Test for gas soundness and carry out functional
checks as appropriate.
Check the sealing panel is correctly refitted, ensuring
that a good seal is made.

INSTALLATION
1.
Light the boiler and carry out a pre-service check, noting
any operational faults.
Run the boiler for at least 20 minutes and check the gas
consumption.
2.
Optional test
Connect a suitable gas analyser to the sampling point on
the boiler.
For correct boiler operation, the CO/CO
boiler 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 Step 3.
3.
Clean the main burner.
4.
Clean the heat exchanger.
Note. This must be done with the heat exchanger and
deposit in a dry condition.
5.
Clean the condensate trap and check the drain for
blockage.
6.
Check that the flue terminal is unobstructed and that the
flue system is sealed correctly.
The servicing procedures are covered more fully in Frames
54 to 60 and MUST be carried out in sequence.
Do NOT OPERATE the boiler if the
sealing panel is not fitted
Note.
In order to carry out servicing, the boiler casing and
sealing panel must be removed. Refer to Frames 54
and 55.
