Servicing Schedule - IDEAL HE15 Installation And Servicing

43 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 annually. It is the law that any service work must be carried
out by a CORGI registered installer. In IE service work must be
carried out by a competent person.
1. Light the boiler and carry out a pre-service check, noting
any operational faults.
2. Check the gas consumption.
3. Connect a suitable gas analyser to the sampling point on
top of the boiler or into the flue terminal, if access is
possible. Refer to Frame 44.
For correct boiler operation the CO/CO
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,
once compliance with the note above is ensured, then no
further action need be taken. If not, proceed to step 4 .
4. Clean the main burner.
5. Clean the heat exchanger and 'S' trap.
