OPERATING THE BOILER
FAULT CONDITIONS:
If the boiler fails to operate.
Check the oil level in the oil storage tank.
Check there is not a power cut and the
power supply to the boiler is switched on.
Check the programmer is set to on.
Check the room thermostat and where fitted,
the radiator thermostats are set correctly.
Remove upper front panel and check the
thermostat control knob (A) is turned on.
If the above checks prove satisfactory and the
boiler remains off, then a safety device in the
boiler control system may have been activated to
prevent the boiler from operating.
Automatic reset:
An excessive boiler operating temperature
can activate a thermostat to switch off the
boiler. This thermostat automatically resets
when the boiler has cooled down sufficiently.
Do not attempt to repeatedly start the boiler
using the manual reset buttons as persistent
failure indicates a fault requiring the attention
of a service engineer.
Boiler overheat (manual reset):
Should the boiler temperature rise beyond
the automatic reset level, a high limit
thermostat will switch the boiler off,
indicated by button (B) standing proud.
When the boiler has cooled down, press
and release (B) to reset the thermostat.
Flue overheat (manual reset):
Excessive combustion gas temperatures can
activate a thermostat to switch off the boiler,
indicated by button (C) standing proud.
Press and release (C) to reset thermostat.
Burner lockout (manual reset):
Flame failure, for any reason, will cause the
burner to go safely to a lockout condition.
Remove the boiler top panel and check the
lockout button (D). If this is illuminated it
indicates a ‘lockout’ condition. To cancel
lockout, wait 2 minutes, then press and
release button (D).
ACCESSING RESET BUTTONS:
Reset buttons (A B & C):
To remove upper front panel pull panel
squarely away from the front of the boiler.
To replace, realign ball studs and push back
into place.
Burner lockout reset button (D):
Pull top panel squarely upwards to
remove.
To replace, realign ball studs and push
back into place.
Always keep pressure to the edges of the
panels to avoid accidental damage.
