The boiler is now running correctly and will proceed to switch itself on and off as the
heating reaches its operating temperature.
If the module green (run) lamp, the upper lamp adjacent to the flame symbol, goes out
and the red light illuminates for more than ten seconds, due to a failure to ignite or an
interruption to the gas supply, turn the boiler off, wait for 10 seconds and turn the boiler
on again as described above in To Light The Boiler. If the boiler still fails to ignite
after three successive attempts contact your Installer or Service Engineer.
NB:
The Keston 260 and Keston 340 displays on the LED display the actual flow
temperature of the boiler. To adjust the required flow temperature hold in the push
button on the sequence controller and rotate the knob until the required temperature is
displayed. When the push button is released the display will revert to showing the actual
flow temperature.
Precautions
Care must be taken at all times to ensure that no blockage or obstruction is
present in the condensate drainage line. In addition the air intake and flue
exhaust terminals of the appliance must be free of obstruction at all times.
Gas Leak or Fault
If you suspect a gas leak turn off the appliance immediately, turn off the gas tap
to the appliance and contact your local gas region without delay.
If you suspect a fault with the appliance it must not be used until the fault has
been corrected by a competent person.
In the unlikely event of a breakdown consult your Installer or Service Engineer
