Instructions for Use
Clearances
A shelf or surround of a maximum depth of 150mm may be
fitted, provided that clearances are as diagram 1, however, for
every extra 25mm above the fire front the depth of the shelf may
be increased by 25mm.
On no account may carpet or other combustible material be laid
directly under the fire front.
Frost
If the boiler is to be out of use for any long time during severe
weather conditions we recommend that the whole of the system,
including the boiler be drained off to avoid the risk of freezing up.
If fitted, switch off the immersion heater in the domestic hot
water cylinder.
If you are in doubt your installation or servicing company or the
local gas undertaking should be contacted.
Electrical Supply
WARNING. The appliance must be earthed.
Connection of the appliance and any system controls to the
mains (230V~50Hz) must be through a 3A fused double pole
isolating switch, having a minimum double pole contact
separation of 3mm, serving only the boiler and system controls.
The colours of three core flexible cable are, Brown - live, Blue
- neutral, Green and yellow - earth.
Safety Device.
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.
If the boiler or fire front shut down frequently, for no apparent
reason, the first things that must be checked are the chimney
and air inlets into the room.
An additional cause of the fire shutting down could be that the
filter in the gas tap is blocked.
Any problems found must be put right, by a competent person,
before the boiler and fire front are used again.
If the burners go out, wait three minutes before relighting, but
check as above.
Lighting the Boiler
The boiler user control is placed behind the ashpit cover.
To remove the ashpit cover unhook from the fret.
Refer to diagram 2 to identify the boiler user control.
See that all other controls are calling for heat.
The clock, room thermostat and programmer, if fitted, will
probably be some distance away 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” fully anti-clockwise so that
the pointer is against the “Reset” position on the boiler user
control panel, see diagram 2.
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 panel
coming on, see diagram 2.
Note: Should the red light on the boiler user control panel 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 panel,
see diagram 2.
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 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
