SAFETY
Do
have the fire installed by a competent person. In the United Kingdom, installation
must be in accordance with the latest edition of the Gas Safety (installation & use)
Regulations. In the Republic of Ireland, installation must be in accordance with all
national and local regulations in force.
Do
have the chimney swept prior to installation if it was previously used for solid fuel.
Do have the fire installed in accordance with the installation instructions.
Do allow a minimum clearance of 760 mm from the top of the base of the convetcor
box to the underside of any shelf whether it is made from combustible or non-
combustible materials. For a shelf made from wood or other combustible materials
deeper than 150mm add 12.5mm to the clearance for every 25mm of additional shelf
depth (See graph 1). Please bear this in mind if ever you add a shelf.

Do provide a suitable guard that complies with BS 8423 for the protection of young
children, the elderly and the infirm. Such a guard is also recommended for the
protection of pet animals. (Although this fire conforms to all the applicable standards, it
is a heating appliance and certain parts of its surface will become hot).
Do wait three minutes before attempting to relight if the fire is switched off or the
flames are extinguished for any reason. (Your fire is fitted with a safety device that will
automatically shut off the gas supply to the fire if, for any reason, the flames go out).
Do get advice about the suitability of any wall covering near your fire. 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.
Do provide a minimum side clearance as detailed below:
The minimum mandatory side clearance to combustible surfaces projecting beyond the
front of the appliance is 100mm. For access purposes a 10mm clearance to non-
combustible surfaces is recommended on the left side of the appliance, on the right side
the recommended clearance is 50mm for access to the slider control.
Please bear this in mind if ever you are considering altering the room.
Don’t hang clothing, towels or any other fabrics over the fire.
Don’t add any extra fuel effect pieces above the number stated in the installer and
owner guide supplied with the ceramic fuel effect.
The installer may have attached it to
this guide or placed it inside
. Adding extra fuel effect pieces could cause a safety hazard
and consequent health hazards.
Don’t put paper or any other material on the fire.
Don’t place any combustible material (rugs, carpet, plastic tiles, etc.) on the hearth.
Don’t
attempt to clean or service the fire until it has been switched off and allowed to
cool completely.

OPERATING YOUR FIRE
The Oxysafe flame sensing and flue blockage safety system.
For your safety, 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.
The device will also automatically shut off the gas supply to the fire if the pilot flame
goes out due to lack of oxygen or for any other reason.
If this device starts to repeatedly shut off the gas, get expert advice.
This device incorporates a probe which senses that the heat from the pilot flame is
correct. If this probe is cool, the device will prevent any gas flow unless the control
knob is held in 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.

OWNER GUIDE
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 use.

To light the fire.
The slide control is shown in figure 1.
1. Slide the control button to the bottom (ignition) position
marked .In this position, the electronic ignition system
should cause a series of sparks that should light the pilot.
Within four seconds of the pilot igniting, the main burner
should light at its minimum setting.
If no sparks are produced to light the pilot, the battery may
need replacing. Details of battery replacement are given
further on in this manual.
Until you can obtain a replacement battery the fire can be lit
with a taper as described later in the instructions.
2.
Keep the button at the ignition position for a further ten seconds. This will prevent
the flame-sensing device from shutting off the gas while its probe warms up as
explained above.
3.
If low heat is required, release the button. The button will automatically spring up to
the low heat position shown in figure 1 (See note i ).
4.
For a higher heat level slide the button upwards. The burner flames and heat output
will gradually increase until the button reaches the high heat position shown in figure 2.
When the button reaches the high heat position you will feel a check to its movement.
Do not slide the button above the high heat position unless you want to turn the
fire off (See note i below).
Note i) If the flames go out while setting the control, repeat the full lighting
procedure. If the flames repeatedly go out have the fire serviced.
ii) Please note. When first turned on the flames will appear predominantly
blue. The fuel effect pieces will take time to warm up. Although some glow
will be seen after approximately ten minutes, the full visual effect will only
be apparent after a somewhat longer time.
iii)
The appliance will operate to its maximum potential if the flue is primed
during the first 20 – 30 minutes of operation. To do this, simply slide the
control button to its highest setting. This will also burn off any carbon
deposits that may have formed during previous operations.
iv)
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.
To turn the fire off.
Slide the button up past the high heat position to the “O” position.
Both the main burner and the pilot should go out.
While cooling, the ceramic fuel effect pieces may make some crackling noises. This is

Lighting with a taper.
(See figure 2).
In the unlikely event of failure of the ignition spark,
the pilot can be lit by a taper or long spill. Insert the
taper or spill between the second and third left hand
ceramic fuel effect pieces on the first row. Operate
the slide control as described above.
CLEANING YOUR FIRE
To maintain the high performance and quality finish of your fire please follow these
guidelines:
Before attempting to clean the fire, please remember to turn off the fire and wait for the
appliance to cool. The fire will retain heat for some time before cleaning can begin.
If any pieces of debris are found in the firebox, have the chimney inspected before
further use.
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.
Ceramic fuel effect pieces and burner compartment walls.
This product uses fuel effect pieces and burner compartment walls containing
Refractory Ceramic Fibres (RCF), which are man-made vitreous silicate fibres.
Excessive exposure to this material may cause irritation to eyes, skin and
respiratory tract. Consequently, it is important to take care when handling these
articles to ensure that the release of dust is kept to a minimum.
!
Light coatings of soot will usually be burnt off during the normal operation of the
fire. Should any soot accumulation become excessive, the fuel effect pieces and walls
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 dust back into the air.
! We suggest that you remove the ceramic fuel effect pieces in the reverse order to
that shown in the fuel bed refitting instructions.
Burner.
Remove any deposits of soot or other foreign matter from the surface of the burner with
a dry soft brush. Be careful not to brush any particles into the open slots. Remove any
particles from the slots with a vacuum cleaner fitted with a soft brush attachment. Do
not poke wire, etc. into the slots in the burner.
CERAMIC FUEL BED REFITTING
The installer and owner guide for the ceramic fuel effect is separate from this guide. The
installer may have attached it to this guide or placed it inside. It is important that the
installer and owner guide for the ceramic fuel effect is followed correctly. If replacing
the ceramic fuel effect, where a new guide is supplied, follow the installer and owner
guide supplied with the replacement fuel effect.
Keep the replacement installer and owner guide with this owner guide for future
reference.
MAINTENANCE
Battery replacement.
This appliance requires one 9V PP3 Ever
Ready Silver Seal (or equivalent) battery.
Fit the new battery firmly to the
connections on the ignition block (See
figure 3).
Regular maintenance.
In order to achieve and maintain high
levels of personal safety and performance
efficiency, it is essential that the opening at
the back of the fire and the flue are kept
clear of any form of obstruction. It is
possible that deposits of mortar or soot could fall and accumulate causing the flue to be
blocked or restricted and so preventing proper clearance of dangerous exhaust fumes.
In the United Kingdom it is the law that a landlord must have any gas appliance, flue

We recommend that all gas appliances and their flues, wherever situated, are checked
annually.
