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 flame goes 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 allowable distance from the outside of the fascia to a corner wall having
combustible material or any other combustible surface which projects beyond the front
of the appliance is 100mm.
A 10mm access clearance from a non-combustible surface is necessary at both sides.
Please bear this in mind if ever you are altering the room.
Don’t hang clothing, towels or any other fabrics over the fire.
Don’t put more loose ceramic fuel effect pieces on the fire than the number given in
this guide or use any ceramic fuel effect pieces other than those authorised for this fire.
Incorrect combustion and subsequent safety hazard could result.
Don’t put paper or other materials onto your fire.
Don’t use the fire with damaged base ceramics.
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.

OWNER GUIDE

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 kept depressed at the “Pilot/Ign” 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.
Lighting the pilot.
This fire is controlled by a 4-position gas tap mounted
on the front leg of the appliance. In addition to the
“Off” position there is a pilot light and 2 heat control
settings (See figure 2).
! Depress the control knob and turn anticlockwise
towards the “Pilot/Ign” position. A spark should be
generated at the pilot while turning. The spark should
ignite the pilot. The pilot flame can be seen through the
lower left hand opening in the front of the ceramic fuel
effect.
! Keep the button depressed at the “Pilot/Ign” position
for a further ten seconds. This will prevent the flame-
sensing device from shutting off the gas while its probe
warms up.
! If the pilot does not ignite instantly, repeat procedure.
If after 10 seconds pilot ignition has not occurred, turn the control knob back to
the “Off” position, wait for 3 minutes and then repeat the ignition procedure.

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.
Figure 2.

Lighting the main burner.
! Once the pilot light is established, the main burner can be lit by depressing and
turning the control knob anticlockwise to the “High” position.
Selecting the heat setting.
!
In order to change from one setting to another depress the control knob slightly and
turn the knob to the required position. Any setting from “Low” to “High” may be
selected.
Note: 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 operate the appliance at its
“High” setting. This will also burn off any carbon deposits that may have formed
during previous operations. If operating the appliance for long periods it is beneficial to
change between settings. This will help to remove any carbon deposits that may form
during operation.
Turning the fire back to pilot setting.
! Depress the control knob and turn clockwise until the pilot setting is reached.
Turning the appliance off.
! Make sure that the control knob is in the pilot position. Depress the control knob
and turn clockwise to the “Off” position.
! Wait at least three minutes before relighting.
Lighting with a taper.
(See figure 3).
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 through the lower left hand opening in
the front of the ceramic fuel effect.
! Follow the section ‘ Lighting the pilot’ as
described previously.

CLEANING YOUR FIRE
To maintain the high performance and quality finish of your appliance, please follow
these guidelines:
!
Before attempting to clean the fire, please remember to turn off the fire and wait for
the appliance to cool completely. 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, lint free non-abrasive cloth and then dry.
! Do not use abrasive cleaners, as these will scratch the fire surface.
Ceramic fuel effect and rear wall.
! This product uses fuel effect pieces and burner compartment rear wall
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 suggest that you remove the ceramic fuel effect in the reverse order to that
shown in the ceramic fuel effect installer and owner guide. This should have been left
inside or attached to this guide by the installer.
Burner
! The burner surface can be carefully cleaned to remove any loose particles after
taking off the ceramic fuel effect. Make sure that no particles are pushed into the burner
holes.

OWNER GUIDE

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
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
and pipework which is situated in a tenant’s premises checked for safety at least every
twelve months by a competent person (In the U.K, a CORGI registered installer).
We recommend that all gas appliances and their flues, wherever situated, are checked
annually.
