•
Explain how, in the event of a fault, the appliance will display a fault code, emphasising that if a fault is indicated
they should note the fault code, turn off the appliance and contact a “competent person” which in normal circum-
stances would be a CORGI registered engineer.
•
Explain and demonstrate the function/operation of time/temperature controls and thermostatic radiator valves,
emphasising the economic use of the appliance.
•
If a programmer has been fitted, hand the user instructions that were supplied with the progammer to the occupier.
•
Point out the water pressure guage and explain what it indicates and that if the pressure falls over a period of time
when the system is cold, a water leak should be suspected and that a “competent person” should be contacted.
•
Emphasise the importance of a regular service and that servicing of the appliance MUST only be carried out by a
“competent person” which in normal circumstances would be a CORGI registered engineer.
•
As the installer you may wish to offer a service contract yourself, or alternatively you may wish to explain to the
occupier that they can take advantage of an extended warranty scheme offered by Johnson & Starley Ltd.
Reminder: following the commissioning and handover of the appliance, complete the Benchmark Log Book and
leave it with the occupier.
5. SERVICING SCHEDULE
To ensure that the appliance gives continued operation that is both safe and efficient, it is necessary to carry out regu-
lar service checks and whilst the period between servicing will depend on the installation condition and the demands
placed upon the appliance, it is recommended that the appliance be serviced annually.
NOTE: it is a statutory requirement that ALL work be carried out by a “competent person” which in normal circum-
stances would be a CORGI registered engineer.
5.1 Servicing Sequence:
•
Light the boiler and carry out a pre-service check, noting any operational faults.
•
Check the gas consumption.
•
Put the appliance in test mode and connect a suitable gas analyser to the sampling point on the top of the boiler
or into the flue terminal if access is possible
(optional test).
For correct boiler operation, the CO/CO
2
content of
the flue gas should not be greater than 0.004 ratio.
Check that the gas input is at least 90% of the
nominal.
•
Clean the main burner.
•
Clean the heat exchanger.
•
Check the condition of the combustion chamber
insulation. Any cracked or damaged pieces should
be replaced.
•
Wherever possible, remove and clean the conden-
sate 'S' trap (refer to section 6.12) and check the
drain for blockage.
•
Check that the flue terminal is unobstructed and that the flue system is sealed correctly.
Note. In order to carry out either servicing or replacement of components the boiler front panel and sealing panel must
be removed. (Refer to section 6.2)
WARNING. Always turn OFF the gas supply at the gas service cock and switch OFF and disconnect the electricity sup-
ply to the appliance before servicing.
•
After completing the servicing or exchange of components always test for gas soundness and carry out functional
checks as described above.
•
When work is complete, the sealing panel MUST be correctly refitted, ensuring that a good seal is made.
WARNING: Do not operate the boiler if the sealing panel is not fitted!
•
lf, for any reason, the condensate 'S' trap has been removed ensure the trap is refilled with water before reassembling.
•
Complete the service section in the Benchmark log book.
Test Mode
To put the appliance in test mode, press both the
MODE
and
T
buttons together for a minimum of 3 seconds.
“TEST” will be displayed in the LCD lower right hand cor-
ner and the flow and return temperatures will be displayed
along with the flame current value. The appliance will stay
in test mode for 30 minutes and the remaining time left in
test mode will be displayed. Whilst in test mode, the
appliance overrides all temperature setting and runs at
minimum rate. Pressing the
S
button will cause the
appliance to run at maximum rate, whilst still overriding
all temperature settings. Press RESET to take the appli-
ance out of test mode.
