INFORMATION FOR THE INSTALLER AND SERVICE ENGINEER.
Under Section 6 of the Health and Safety at Work Act 1974, we are required to provide information on substances hazardous to health.
The Adhesives and sealants used in this appliance are cured and give no known hazard in this state.
REFRACTORY CERAMIC FIBRE
This product uses fuel effect Pieces containing Refractory Ceramic Fibre (RCF), which are man-made vitreous silicate fibres.
Excessive exposure to these materials may cause temporary irritation to eyes, skin and respiratory tract, consequently, it makes
sense to take care when handling these articles to ensure that the release of dust is kept to a minimum.
To ensure that the release of fibres from these RCF articles is kept to a minimum, during installation and servicing we recommend
that you use a HEPA filtered vacuum to remove any dust and soot accumulated in and around the fire before and after working on
the fire. When replacing these articles we recommend that the replaced items are not broken up, but are sealed within heavy duty
polythene bags, clearly labelled as RCF waste. This is not classified as “hazardous waste” and may be disposed of at a tipping site
licensed for the disposal of industrial waste. Protective clothing is not required when handling these articles, but we recommend you
follow the normal hygiene rules of not smoking, eating or drinking in the work area and always wash your hands before eating or
drinking.
INSULATION and SEALS
Ceramic fibre and glass fibre used in insulation panels rope and gaskets.
These can cause irritation to skin, eyes and the respiratory tract.
If you have a history of skin complaint you may be susceptible to irritation. High dust levels are usual only if the material is broken.
Normal handling should not cause discomfort, but follow normal good hygiene and wash your hands before eating, drinking or going
to the lavatory.
If you do suffer irritation to the eyes or severe irritation to the skin seek medical attention.
Spare Parts
REMEMBER, When replacing a part on this appliance, use only spare parts that you can be assured conform to the safety and
performance specification that we require. Do not use reconditioned or copy parts that have not been clearly authorised by Hepworth

Safety Device.
This appliance is fitted with a flue blockage safety device which
will shut down the appliance in the event of abnormal flue
conditions. This device is NOT a substitute for an independently
mounted Carbon Monoxide detector.
If the boiler or fire front shut down frequently, for no apparent
reason, the first things that must be checked are the chimney
and air inlets into the room.
An additional cause of the fire shutting down could be that the
filter in the gas tap is blocked.
Any problems found must be put right, by a competent person,
before the boiler and fire front are used again.
If the burners go out, wait three minutes before relighting, but
check as above.
Lighting the Boiler

1.1 Important Notice
This fire front is for use only on G20 gas.
The back boiler is supplied pre-set to a maximum heat output
setting, for the 45/4 BBU: 11.72 kW (40000 Btu/h), for the 54/4
BBU: 14.21 kW (48500 Btu/h).
These values are permitted and must not be increased when
using the boiler in combination with a Chatsworth 4 or a
Dovedale 4 firefront.
221907B
8
1 General
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.
