Pump Overrun

The boiler controls operate the pump for several minutes
after the shut down of the boiler to prevent overheating. The
boiler controls will also operate the pump for a few minutes
every 24hrs, to maintain the free running of the pump.

Other Controls

A Potterton Electronic Programmer or other type of clock
may have been fitted in your system, together with room
and/or cylinder thermostats. Full instructions on the use of
these controls should be supplied with them.

Important

Gas and electricity are required to operate your boiler. Its
performance will not be affected by normal variation in
either supply, but a gas or electricity failure will put the boiler
out of operation. It will automatically re-start when the
supply is restored provided that the time clock and/or
thermostats are in the 'On' position.

Note: If the boiler is running and the gas is turned Off, the
boiler will switch off and attempt to light twice, after which the
Red L.E.D. will flash. The Reset Button will have to be
pressed before the boiler will relight.

Overheat Limit Thermostat

The boiler is fitted with a safety thermostat to protect against
overheating of the water. If this thermostat operates the
boiler will lockout and the Red L.E.D. will start to flash. Press
the reset button (

Do Not use excessive pressure), the Red

L.E.D. will stop flashing and the boiler will attempt to re-light.
If the control does not reset, leave the boiler for approx. 15
minutes before pressing the reset button again.

If the problem persists, turn off the boiler and consult your
Local Installer or Service Engineer. Note: Interruption of the
electrical supply to the boiler may also cause the overheat
thermostat to operate.

Having checked these points, run through the lighting

Frost Precautions

If your boiler has to be shut down for several hours or more
during very cold weather, it may be in danger of freezing,
due to its position, i.e. it may be in an outhouse or part of the
pipework may be vulnerable to frost. To avoid freezing,
various methods of protection can be used:-

1. Insulation of the boiler and pipework, taking care not to

impede any ventilation or air supply.

2. Completely draining the water system if not in use for

long periods. On a sealed system, draining and refilling
must be carried out by a competent person.

Note: Although the system can be emptied by using the
drain off taps installed in the pipework around the system,
to empty the boiler, it is necessary to remove the drain
screw which is situated on the heat exchanger casting.
This should only be done by a competent person.

3. Have a low limit thermostat fitted. If the system is fitted

with a low limit thermostat and protection of the system
is required during cold weather, all that is required is for
the programmer to be turned to the 'Off' position. This will
allow the boiler to operate if the temperature within the
house becomes too low. The low limit thermostat will not
operate if the boiler is completely shut down and the
electricity supply turned off. In this instance, the system
will have no protection and one of the other methods
must be used.

4. Where no frost protection is provided it may be necessary

to run the boiler at low thermostat settings at all times
when it would normally be shut off.

Cleaning the Outside of the Boiler Casing

The outside of the boiler casing can be wiped when
necessary by using a damp cloth to remove finger marks
etc. Do not use an abrasive cleaner as this may damage the
casing finish.

Information for the Suprima System Boiler

The system water pressure should be checked periodically.
This is done by removing the lower cover, released by
pulling forward at the base, to expose the pressure gauge.
The gauge is situated on the right hand side of the pump. If
the needle falls below the point indicated by the red marker,
this shows water is leaking from the system and that it needs
re-charging. Your installer can advise you on what to do with
your particular
system. Re-fit
the cover into
the spring clips
after checking.
