hot. DO NOT PLACE YOUR HANDS under the tap or use the shower until this initial flow has passed.
- Allow time (30 seconds) for the temperature to stabilise after making an adjustment at the tap before mak-
ing further adjustments.
APPLIANCE SAFETY
LOCK-OUT
This boiler has a cut-out indicator built in to it. Whenever a malfunction is detected in the boiler, the boiler
switches off automatically and the cut-out indicator lights up (red indicator light) To reset the boiler rotate the
main control knob to the position and go back to the chosen position. Some lockout sequences require the
thermistors to cool to within normal operating temperatures before the boiler will reset. 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 purged from the system.
FROST PROTECTION
Providing the boiler power supply and gas supply is connected the boiler will automatically fire on minimum
when near freezing conditions are detected. When the temperature in the system reaches 20°C it will
switch off. For winter storage see notes at the end of this section.
NOTE:It is still necessary to drain the domestic hot and cold water system.
ANTI PUMP SEIZURE DEVICE
When central heating is not being used, but the boiler is in the summer setting (for domestic hot water only)
the pump will automatically run for one minute every 24 hours to prevent it seizing. If the appliance has been
shut down with the 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, consult your installer or service engi-
neer.
NOTE: seized pumps are not covered under warranty.
PRESSURE GAUGE
The pressure gauge should indicate approximately between 0,8 and 1,6 bar. If the pressure is seen to
decrease over a period of time there is a water leak. The boiler is fitted with a safety device to prevent it work-
ing below a pressure of 0.8 bar.
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 room sealed 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 liable to freeze, 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
-Release the drain plugs fitted at the lowest point of the pipework.
NOTE: There is no drain plug fitted to the DHW side of 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 supply.
NOTE: In a Caravan Holiday Home installation there may be a drain cock on the cold inlet under the
van directly below the boiler which may be used. It is not necessary to drain the heating circuit if it
has been filled with antifreeze.
