Remote appliance diagnostic system
This appliance is capable of automatically communicating
operational data to a central computer processing system via the
house ring main and telephone line, known as 'Remote Appliance
Diagnostic System' (RADS).
The information is transmitted in the early hours of the morning
once every 30 days, or immediately if the boiler develops a fault.
If an attempt is made to use the telephone during the
transmission, some interference will be heard. In this event
replace the receiver and try again after 30 seconds.
Important Points
a.
If the boiler is installed in a compartment then the compartment
MUST NOT be used for storage purposes.
b.
The ventilation provided for the boiler during installation MUST
NOT be blocked, and a check should be made periodically that
the ventilation areas are free from any obstruction.
c.
If it is known or suspected that a fault exists on the boiler then it
MUST NOT be used until the fault has been corrected by a
CORGI
registered installer.
d.
Flammable materials must not be placed in close proximity to
the appliance. Materials giving off flammable vapours must not
be stored in the same room as the appliance.
e.
Under NO circumstances should any of the sealed components
on this appliance be used incorrectly or tampered with.
In cases of repeated or continuous shutdown
a
CORGI
registered
installer should be called to investigate and rectify the condition
causing this and carry out an operational test after each intervention
on the device. Only the manufacturer's original parts should be
used for replacement.
Minimum clearances
A clearance of 533mm (21") MUST be available at the front of the
boiler for servicing.
The minimum clearances given in Table 1 MUST be complied with,
in order to maintain the safe running of the boiler.
To light the boiler.
