This fire is certificated to the current issue of BS6332 part 2, invoking the current issue of BS5258 part 8 for safety and performance.
It is, therfore, important that no alteration is made to the fire, without permission, in writing, from Hepworth Heating Ltd.

Any alteration that is not approved by Hepworth Heating Ltd., could invalidate the certification, the warranty and could infringe the
statutory requirements.

CE Mark

The CE mark on this appliance shows compliance with:

1. Directive 90/396/EEC on the approximation of the laws of the Member States relating to appliances burning gaseous fuels.

2. Directive 73/23/EEC on the harmonization of the Laws of the Member States relating to electrical equipment designed for use

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.

FUELBED

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 PADS, CERAMIC FIBRE, GLASS YARN & SEALANT

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.

SERVICING

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
Heating Ltd.

Electrical Supply

WARNING. The appliance must be earthed.

Connection of the appliance and any system controls to the
mains (230V-50Hz) must be through a 3A fused double pole
isolating switch, having a minimum double pole contact
separation of 3mm, serving only the boiler and system controls.

The colours of three core flexible cable are, Brown - live, Blue

laid directly under the fire, unless the minimum clearances
shown in diagram 1, is achieved.

The dimension is taken from the bottom of the fire case to the
top of the carpet pile or other floor covering.

Maintenance

To ensure the continued efficient and safe 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 installation and usage, but in general
once a year should be enough.

If this appliance is installed in a rented property there is a duty
of care imposed on the owner of the property by the current
issue of the Gas Safety (Installation and Use) Regulations,
Section 35.

It is the law that servicing must be carried out by a competent
person.

Hearth

A fire proof hearth under the fire front must have the minimum
dimensions as shown in diagram 2.

OPERATING YOUR BOILER AND FIRE

Safety Device

BOILER

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.

FIRE FRONT

shut it down if there is a lack of oxygen it also incorporates a
probe which senses that the heat from the pilot flame is correct.
If the probe is cool, the device will prevent any gas flow unless
the control knob is held down at the ignition position.

If, for any reason, the flames go out when the fire is hot or if the
fire is turned off when hot, always wait at least three minutes
before attempting to relight.

If the boiler and/or fire shuts down frequently for no apparent
reason the first things to be checked are the chimney and air
inlets into the room.

Any problems found must be put right, by a competent person,
before the appliance is used again.

- This appliance is fitted with a flue blockage safety

- The fire is fitted with a safety device which will

Lighting the boiler

The boiler controls are situated at the bottom of the R/H louvre
of the fire front.

Refer to diagram 3 to identify the boiler controls.

See that all other controls are calling for heat.

The clock, room thermostat and programmer, if fitted, will
probably be some distance from the unit.

To see how these items work and need to be set, read the
manufacturers instructions supplied with them.

Turn the control thermistor knob “A” so that the pointer is
between maximum and minimum, "O" on the boiler user control,
see diagram 3.

Switch on electrical supply to the back boiler.

There will be a purge for approximately 30 seconds.

NOTE: If the electrical supply is switched rapidly off and on
without gas present the control will purge for 100 sec. Neither
of the indicators will be lit. The appliance will then operate
correctly.

The boiler will automatically light.

This is indicated by a green light on the boiler user control
coming on, see diagram 3.

Note: Should the red light on the boiler user control come on, it
indicates that the pilot light is not operating correctly, or the flue
blockage safety device has been activated.

When the fault has been corrected, turn the control thermistor
knob “A” fully anti-clockwise so that the pointer is against the
“Reset” position on the boiler user control, see diagram 3.

NO ATTEMPT SHOULD BE MADE TO RELIGHT THE BOILER
UNTIL ANY FAULT HAS BEEN CORRECTED. EXPERT
ADVICE SHOULD BE SOUGHT.

Adjust the control thermistor knob to the required setting between
the minimum, "O" and maximum position.

o

Maximum is approximately 82

The temperature of the hot water cylinder should be periodically
raised to 60

Check that all external controls are also set to your requirements.

If the burner goes out for no apparent reason it is IMPORTANT
that the advice given under “Safety Device” is followed.

Instructions for Use

To turn the boiler off

For short periods, turn the control thermistor knob “A” fully anti­clockwise so that the pointer is against the “Reset” position on
the boiler user control, see diagram 3.

To relight the main burner turn control thermistor knob “A”
clockwise to the desired setting between the minimum, "O" and
maximum position.

For longer periods, turn the control thermistor knob “A” to
“Reset” position. Switch off the electrical supply to the boiler.

To relight follow the full lighting instructions given above.

Lighting the fire

Please note:

When operating your fire for the first time, some vapours may
be given off which may cause a slight odour and could possibly
set off any smoke alarms in the immediate vicinity. These
vapours are quite normal with new appliances. They are totally
harmless and will disappear after a few hours.

To light the fire

The control is shown in diagram 4.

Depress the control knob and turn partially to the 1/IGN position
until you feel some resistance.

Keep the knob depressed at this position for a few seconds to
allow gas to flow to the burner.

While keeping the knob depressed, turn to the 1/IGN position.
While turning, a spark should light the pilot.

Keep the knob depressed at the 1/IGN position for a further 10
seconds then release it. The centre section of the coal will be
alight at this position.

Depress the control knob slightly and turn it to your desired
burner setting.

The control knob should be depressed slightly before turning
whenever you are changing the burner setting.

The burner settings are ;

1/IGN.............Centre section on low. Outer sections off.

2.................... Centre section fully on. Outer sections off.

3.................... Centre section fully on. Outer sections on low.

4.................... Centre section fully on. Outer sections fully on.

We recommend that the fire is set at position 4 for the first 10
minutes after lighting to warm up the chimney and so obtain full
efficiency quickly.

If operating the appliance for long periods it is beneficial
occasionally to change the settings. This will also help to
remove any carbon deposits that may form during operation.

Note: If the fire goes out while setting the control, repeat the full
lighting procedure. If the fire repeatedly goes out, have the fire
serviced.

TAPER OR SPILL

Diagram 5

Lighting with a taper

In the unlikely event of failure of the ignition spark, the pilot can
be lit with a long taper or spill after the glass panel surround and
glass panel assembly has been removed. Removal of these
parts is descibed in the "Glass Panel" section.

Insert the taper or spill into the centre opening in the ceramic
coal while the control is kept depressed at the 1/IGN position
see diagram 5.

When the pilot has lit follow the rest of the instructions in the
section headed "To light the fire". Always replace the window
unit after lighting.

Metal Parts

Clean the metal parts with a slightly damp cloth and then dry.

Do not use abrasive cleaners as these will scratch the fire
surface.

To turn the fire off

Partially depress the control knob and turn clockwise to OFF.
Release the knob.

Wait at least 3 minutes after turning the fire off before relighting.

Instructions for Use

Cleaning

Turn the fire off and allow it to cool before attempting any
cleaning.

Normally the fire will only need dusting. The bright metal trims
may be cleaned with a damp cloth and dried with a soft duster.

Obstinate marks can be removed from the guard and trims using
soapy water. Never use abrasive cleaners.

Glass Panel

Remove any stains on the glass panel with a non-abrasive
cleaner such as a ceramic hob cleaner. Do not use abrasive
cleaners.

The fire has been designed to so that you can remove the glass
panel without having to call in a service engineer. This allows
you to clean the inside of the glass.

To remove the glass panel assembly:

Unscrew and remove the two knurled screws which are under
the outer case canopy, see diagram 6.

Pull the top of the glass panel surround forward, see diagram 6.

Lift the surround up to clear the slots in the case apron.

Put the surround in a safe place.

Remove the glass panel assembly by turning the screws each
side of the frame
your fire for turning the screws. Lift the assembly clear, see
diagram 6.

After cleaning, replace and secure the glass panel assembly to
the firebox by turning the two screws
tool provided. Replace the surround. Make sure that the outside
edges of the surround sides are inside the outer case.

Ceramic Coal

This product uses a fuel effect piece containing Refractory
Ceramic Fibres (RCF), which are man-made vitreous silicate
fibres. Excessive exposure to this material may cause temporary
irritation to eyes, skin and respiratory tract. Consequently, it
makes sense to take care when handling this article to ensure
that the release of dust is kept to a minimum.

Although light coatings of soot are usually burnt off during
normal use, the coal may benefit from occasional cleaning.

Should any soot accumulation become excessive, the fuel
effect piece should be removed from the fire for cleaning.
Cleaning should be carried out in a well ventilated area or in the
open air by gently brushing with the pieces held away from your
face so that you avoid inhaling the dust. We do not recommend
the use of a normal domestic vacuum cleaner which may blow

9486

dust back into the air.

The coal can be lifted out of the fire box when the glass panel
surround and glass have been removed as described above.

When replacing the coal, make sure that it rests on the ledges
at the sides of the firebox and that its back face is touching the
horizontal rib at the back of the firebox, see diagram 7.

Replace the glass panel assembly and surround after cleaning.
