APPLIANCE SAFETY LOCK-OUT
This boiler has a cut-out indicator built in to it. Whenever a malfunction is detected in the ignition of the boil-
er, the boiler switches off automatically and the cut-out indicator lights up (red indicator light) To reset the boil-
er press the restart switch. The red indicator light should go out. IMPORTANT: Whenever the boiler has been
left idle for any length of time, or when a new gas bottle is installed (propane models), the appliance may
switch off due to the presence of air in the pipes. In cases such as these, repeat the ignition operation until
all of the air has been vented from the system.
FROST PROTECTION
Providing the boiler power supply and gas supply is connected and the main control switch is in the summer
setting the boiler will automatically fire on minimum setting when near freezing conditions are detected. When
the temperature in the system reaches 30
°
C it will switch off. For winter storage see notes at the end of this
section.
ANTI PUMP SEIZURE DEVICE
When central heating in not being used, but the boiler is in the summer setting (for domestic hot water only)
the pump will automatically run for three minutes every 24 hours to prevent it seizing. If the appliance has
been shut down with the gas and electrical supply switched off for a period, this device will not work. The
pump may be found to have jammed when the appliance is switched back on. If so, refer to “Routine
Servicing”page 19 .
PRESSURE GAUGE
The pressure gauge should indicate approximately 1 bar. If the pressure is seen to decrease over a period of
time there is a water leak. Consult your installer or service engineer.
ROUTINE SERVICING
To ensure continued safe and efficient operation of the appliance it is recommended that it is checked and
serviced as necessary at regular intervals. The frequency of servicing will depend upon the particular instal-
lation conditions and usage but in general once a year should be regarded as a minimum even if only occa-
sional usage has occurred. It is the law that any service work MUST be carried out by a registered engineer
such as CORGI registered personnel.
SAFETY
It is essential that these instructions are strictly followed for the safe and economical operation of this appli-
ance. The appliance is a fan-assisted balanced flue gas boiler and therefore the flue terminal MUST NOT BE
OBSTRUCTED under any circumstances. If it is damaged, turn off the appliance and consult your installer,
or service engineer. If it is known or suspected that a fault exists on the appliance it MUST NOT be used until
the fault has been rectified by a competent person.
PRECAUTIONS AGAINST FREEZING DURING WINTER STORAGE
During cold periods and if the boiler is situated in a place exposed to frosts, the D.H.W. circuit must be drained
down as follows:
- Turn off the cold water Supply
- Open all the hot water outlet taps on the installation (at least one tap should
be found at a level lower than the heater).
- Release the drain plug (shown opposite) which can be seen from under the
boiler.
- When the operation is finished, close the hot water outlet taps and replace
the drain plug.
- To put the boiler back into service, open the cold water inlet tap.
NOTE: In a Caravan Holiday Home installation there may be a drain cock on
the cold inlet under the van which may be used instead of the drain plug on the boiler.
NOTE: It is not necessary to drain the heating circuit if the heating circuit has been filled with anti-freeze.
