Graph 1. Combustible shelf clearances

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.
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 altering the room.
Don’t hang clothing, towels or any other fabrics over the fire.
Don’t put more 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 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.
The control markings are shown in figure 2.
u 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.
u
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

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. Control markings

explained above.
u
If low heat is required, release the button. The button will automatically spring up
to the low heat position shown in figure 2 (See note i).
u
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).
Notes:
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. When first turned on the flames will appear predominantly blue. The ceramic fuel
effect 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 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 to change between settings.
This will also help to remove any carbon deposits that may form during operation.
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 fuel effect bed.
! 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 EFFECT 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.
The igniter unit uses a 9V PP3 battery. To replace the
battery remove the firefront casting / front cover
casting.
1. Remove and discard the battery from the ignition
block located below the burner tray at the left side.
2. Fit the replacement battery to the ignition block.
(See figure 4). The positive terminal (+) is to the top
as you insert.
3. Replace the firefront casting / front cover casting.
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.
