OPERATING YOUR BOILER AND FIRE
Safety Device
BOILER - This appliance is fitted with a flue blockage safety
device which will shut down the appliance in the event of
abnormal flue conditions. This device is NOT a substitute for an
independently mounted Carbon Monoxide detector.
FIRE FRONT- The fire is fitted with a safety device which will
shut it down if there is a lack of oxygen it also incorporates a
probe which senses that the heat from the pilot flame is correct.
If the probe is cool, the device will prevent any gas flow unless
the control knob is held down at the ignition position.
If, for any reason, the flames go out when the fire is hot or if the
fire is turned off when hot, always wait at least three minutes
before attempting to relight.
If the boiler and/or fire shuts down frequently for no apparent
reason the first things to be checked are the chimney and air
inlets into the room.
Any problems found must be put right, by a competent person,
before the appliance is used again.
Lighting the boiler
The boiler controls are situated at the bottom of the R/H louvre
of the fire front.
Refer to diagram 3 to identify the boiler controls.
See that all other controls are calling for heat.
The clock, room thermostat and programmer, if fitted, will
probably be some distance from the unit.
To see how these items work and need to be set, read the
manufacturers instructions supplied with them.
Turn the control thermistor knob “A” so that the pointer is
between maximum and minimum, "O" on the boiler user control,
see diagram 3.
Switch on electrical supply to the back boiler.
There will be a purge for approximately 30 seconds.
NOTE: If the electrical supply is switched rapidly off and on
without gas present the control will purge for 100 sec. Neither
of the indicators will be lit. The appliance will then operate
correctly.
The boiler will automatically light.
This is indicated by a green light on the boiler user control
coming on, see diagram 3.
Note: Should the red light on the boiler user control come on, it
indicates that the pilot light is not operating correctly, or the flue
blockage safety device has been activated.
When the fault has been corrected, turn the control thermistor
knob “A” fully anti-clockwise so that the pointer is against the
“Reset” position on the boiler user control, see diagram 3.
NO ATTEMPT SHOULD BE MADE TO RELIGHT THE BOILER
UNTIL ANY FAULT HAS BEEN CORRECTED. EXPERT
ADVICE SHOULD BE SOUGHT.
Adjust the control thermistor knob to the required setting between
the minimum, "O" and maximum position.
Maximum is approximately 82 o C.
The temperature of the hot water cylinder should be periodically
raised to 60
o C.
Check that all external controls are also set to your requirements.
If the burner goes out for no apparent reason it is IMPORTANT
that the advice given under “Safety Device” is followed.
To turn the boiler off
For short periods, turn the control thermistor knob “A” fully anti-
clockwise so that the pointer is against the “Reset” position on
the boiler user control, see diagram 3.
