Notes and General Information

These instructions should be read and carefully followed for the
safe and economical use of your appliance.

These gas fire fronts are to be used with specially designed
Glow-worm 45/4 & 54/4 Back Boiler Units only.

The fire front and back boiler must be installed as a complete
unit.

The boiler and fire can be operated together or independently.

Important Notice

This appliance is for use on natural gas (G20) as distributed in
the United Kingdom and Ireland and must not be used on any
other gas.

A slight smell may occur for a short time after initial lighting, this
is quite normal and with use it will quickly disappear.

Combustible furniture or materials must not be placed closer
than 1m (39in) in front of the fire front.

Soft wall coverings(e.g. embossed vinyl, etc.) which have a
raised pattern, are easily affected by heat. They may, therefore,
scorch or become discoloured when close to a heating appliance.
Please bear this in mind whenever you are considering
redecorating

The convection air openings at the top of the fire front and air
inlet grilles at the sides and base must never be restricted.

Never use the fire with damaged radiants.

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.

Please be advised that the ‘Benchmark’ logbook (supplied with
the Back Boiler Unit) should be completed by the installation
engineer on completion of commissioning and servicing.

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

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.

The radiants can be cleaned with a soft brush - see diagram 7,8
& 9 which shows how to remove the dressguard and radiants.

Frost

If the boiler is to be out of use for any long time during severe
weather conditions we recommend that the whole of the system,

water cylinder.

If you are in any doubt your installation or servicing company or
the local gas undertaking should be contacted.

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.

Instructions for Use

Lighting the boiler

The boiler control is situated at the bottom of the R/H louvre of
the fire front.

Refer to diagram 4 to identify the boiler control.

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 4.

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 4.

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 panel,

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.

Maximum is approximately 82

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

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.

see diagram 4.

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 5.

Depress the control knob and turn anticlockwise towards the 1/
IGN position, two audible clicks will be heard. A spark should
be generated at the pilot while turning. The spark should ignite
the pilot. The pilot flame can be seen through the opening
immediately below the centre radiant, see diagram 6.

If the pilot does not light, turn the knob back to OFF and try
again.

In the unlikely event of failure of the ignition mechanism the pilot
can be lit with a long match or taper.

When the pilot has lit keep the knob depressed for about ten
seconds to allow the flame sensing probe to warm up.

The control knob can then be set to your preferred heat level.
The settings are:

Knob Radiants Condition
Position

2 Centre radiant on low. Outer radiants off.

3 Centre radiant fully on. Outer radiants off.

4 Centre radiant fully on. Outer radiants on low.

5 All radiants fully on.

To turn off partially depress the knob and turn clockwise to off.
Wait at least three minutes before attempting to relight.

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 4.

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

Instructions for Use

Lighting with a match or taper

Depress the control knob and turn anticlockwise towards the
1/IGN position.

While keeping the knob depressed, light the pilot by inserting a
long match or taper into the pilot viewing opening
(See diagram 6 ).

When the pilot is alight, keep the knob depressed for about ten
seconds to allow the flame sensing probe to warm up before
setting to your preferred heat level.

For your own convenience, have the fire serviced as soon as
possible.

To Turn Off

Push gas tap knob in and fully clockwise to "Off".

Replacing the radiants

Turn the fire off and allow it to cool before attempting to remove
the radiants.

For Miami remove the dress guard by holding the outer edge
and flexing the centre outwards to release the upper and lower
locating pins, see diagram 7.

For Firelite & Contour remove the dress guard by pressing down
the two hooks at the top. Tilt the guard forward and lift out, see
diagram 7.

Lift the centre radiant from the bottom and withdraw forwards,
move the other radiants to the centre and remove in a similar
way, see diagram 8.

To replace, insert top of radiant first, then the bottom and lower
into position, see diagram 9.

Replace the dress guard.

It is suggested that the position of the radiants be changed from
time to time.
