A new data label, supplied with fire front loose items pack, must
be stuck over the top of the BBU data label, see diagram 1.1.
Care must be taken when oversticking the label on top of the
original as not to obscure the boiler serial number.
The fire front is fitted with a flue blockage safety device which
will shut it down if there is a lack of oxygen. The principle by
which this operates is that when there is a depletion of oxygen
resulting from a build up of combustion products. The flame on
the pilot light will become unstable and lift up off the thermocouple.
This will deactivate the mag unit in the gas control valve, cutting
off the gas supply.
If the fire shuts down frequently for no apparent reason the first
things to check are the chimney and air inlets into the room. Any
problems found must be put right, by a competent person, and
a full operational test carried out before the fire is used again.
IN ALL cases the room must be ventilated before attempting to
relight the fire.
The flue blockage safety device incorporates the electrode,
thermocouple and pilot assemblies.
The flue blockage safety device MUST NOT be adjusted or
disconnected. It must be serviced strictly in accordance
with the instructions in this book. Any unauthorised
interference could result in the device failing to operate,
creating a potentially dangerous situation. If replacing, use
only the correct and approved parts.
Sealed components must not be interfered with.
Servicing instructions and identification of parts is given in
Sections 6, 7, 8 and 9.
It is essential that only genuine Glow-worm parts are used.
All WARNINGS and cautions in these instructions must be
observed.

be taken when handling sheet metal parts, to avoid any possibility
