The indicator lights will operate in the following order.
1. Demand light on.
2. Service indicator light on.
3.Ignition light illuminated only during ignition.
4.Temperature indicator lights show increasing water
temperature.
5. High/Iow flame lights indicate the level of firing
of the main burner.
The water temperature of the central heating and hot
water circuits can be controlled separatelyaspreviously
described. It is suggested that both thermostat control
knobs are set to their mid setting initially. The user can
adjust the controls upwards or downwards in
accordance with their heating and hot water
requirements.
While the appliance is being usedto provide hot water,
at any draw off point, the central heating will not
operate.When hot water is no longer required the
appliance will automatically revert to central heating.
For normal hot water draw off, this will not noticeably
affect the level of central heating.
The appliance is designed to operate throughout the
year.When central heating is no longer requiredswitch
the right hand summer/winter switch to the summer
position. This will allow the appliance to function
normally for domestic hot water requirements but the
central heating system will not operate.
Switch the boiler on/off switch to OFF.For long
periodsof shut-down, (sayseveralmonths) the gasand
electricity supply should be turned off to the appliance.
The appliance is fitted with severalprotection devices.
Operation of any of these devices will result in the
appliance failing to operate.
In most casesswitching 'OFF' the boiler on/off switch
for a period of at least 30 seconds, and then switching
on again will restore the boiler to normal operation.
If this is not the case refer to the preliminary fault
finding chart at the back of this booklet.
The pressuregauge on the left handside of the control
panel indicates the pressure in the central heating
circuit.If the needlefalls below the point indicated by
the red marker, this indicatesthat water has leaked out
of the system and iflquires recharging. Your installer
can advise you on· what to do with your particular
system.
If the appliance is not in usefor severalhours or more
during very cold weather there may be a possibilityof
freezing.
To avoid freezing, three methods of protection can be
used:-
1. Insulation of the applianceand pipework taking care
not to impede any ventilation air supply.
2. Leave the appliance running on the lowest room
thermostat setting.
3. Having a special low limit thermostat fitted.Seek
advice from your installer.
If a low limit thermostat has beenfitted, or the central
heatingisto beleft running, the mainselectricity supply
must be left on.
If the appliance is to be out of usefor a long period in
winter,then the appliance should be drained unless a
low limit thermostat is used.
Similarly, refilling must bedone bya competent person,
e.g. your service engineer.
Fornormal cleaningwipe overthe painted surfaceswith
a damp cloth, then with a dry cloth, dry off the surfaces
and lightly polish. A good brand of silicone furniture
spray polish can be used to protect the painted
surfaces.
The control panel and switches can be wiped witha
damp cloth and dried as for painted surfaces.Spray
polishesmust not beusedon the control panelsurfaces
or switches and care must be exercised in preventing
any liquids entering the appliance.
Regularskilled servicingis requiredto maintainthe safe
and efficient operationof your boiler throughout its long
working life. It is recommended that this appliance is
servicedat leastonce a year, and it is advisableto have
the whole heating system checked over so that
excessivecosts are not incurred by such things asair
temperature thermostats or radiator valves getting out
of adjustment.
Servicing should be carried out by a trained service
engineer,and it is suggestedthat an annual contract be
arranged. Contact your local Potterton RegionalService
Office or return the post card supplied with this booklet
for further information.
Gas and electricity are required to operate your
appliance. The appliancewill not beaffected by normal
variations in gas or electricity supply, but a gas or
electricity failure will put the applianceout of operation.
It will automatically restart when the electrical supply is
restored provided that the time clock and/or
thermostats arein an ONposition. On restoration of the
gas supply it will normally be necessaryto switch the
boiler off for a period of 30 seconds,then on again
before the appliance can restart. If a gas leak is
suspectedturn off the applianceand consult your local
gas region or service engineer.
