- Caution: The boiler can produce water at over 70°C when in central heating mode. If you run a hot
tap when the boiler has been heating the radiators, the initial flow through the hot tap could be very
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 making further adjustments.
APPLIANCE SAFETY LOCK-OUT
Whenever a malfunction is detected in the boiler, the boiler switches off automatical-
ly and the red LED lock-out indicator lights up along with the digital display (see P19)
To reset the boiler turn the left main control knob (3) to the position and go back
to the chosen position. Some lockout sequences require the sensors to cool to with-
in 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 30 seconds every 23 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 on the central heating system.
The boiler is fitted with a safety device to prevent it working 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 competant gas registered engineer.
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 competant gas registered engineer.
