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 guide.
Do
provide a minimum clearance of 860mm from the base of the fireplace opening to
any shelf made of wood or other combustible material where the shelf is not more than
150mm deep. For a shelf deeper than 150mm, add 12.5mm to the clearance for every
25mm of additional shelf depth (See graph1).
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 in figure 1. Please bear this in mind if
ever you are considering altering the room.
Don’t hang clothing, towels or any other fabrics over the front of the fire.
Don’t
add any extra ceramic fuel effect pieces above the number stated in the installer
and owner guide supplied with the ceramic fuel effect. This should have been placed
inside or attached to this guide by the installer. This could cause incomplete combustion
and consequent safety hazard.
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 THE FIRE
The Oxysafe flame sensing & flue blockage safety system.
For your safety, this appliance is fitted with a flue blockage safety device that 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 that 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.
To light the fire.
Depress the control knob and rotate it anticlockwise to the pilot ignition position. A
‘click’ will be heard as the integral piezo operates. A flame should appear at the pilot.
Keep the control knob depressed and hold the pilot ignition position for ten seconds.
When the control knob is released the pilot
flame should remain lit. If a flame does not
appear at the pilot then turn the control knob
clockwise to the ‘OFF’ position and repeat the
above.
When the pilot burner is operating properly,
gradually turn the control knob anti-clockwise
to ‘HIGH’ position. (Depress the knob slightly
to get past the pilot ignition position). The main
burner should now light.
Depress the control knob slightly to release
from the ‘HIGH’ position and turn back
(clockwise) to ‘LOW’. While turning, the
burner flames should gradually become lower but remain alight. Depress the control

Figure 2. 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 use.

knob slightly to release from the ‘LOW’ position and turn back (clockwise) to the Pilot
ignition position. The main burner should extinguish but the pilot should remain alight.
Depress the control knob slightly and turn back (clockwise) to turn OFF. This will
extinguish the pilot.
While cooling, the ceramic fuel effect may make some crackling noises. This is quite
normal.
! If the flames go out while setting the control, repeat the full lighting procedure.
! If the flames repeatedly go out have the fire serviced.
!
Please note. 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.
!
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 turn the control knob to 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 occasionally to change
the 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 between the second and
third left hand ceramic fuel effect pieces on the
first row. Operate the control knob as described in
the section headed ‘To light the fire’.

CLEANING
Turn the fire off and allow it to cool completely before attempting any cleaning. Note
that the fire will retain heat for some time after it has been turned off.
If large pieces of debris are found anywhere in the fireplace, 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, they could scratch the surface.
Ceramic fuel effect .
This product uses fuel effect pieces 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 ceramic fuel effect pieces
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 that 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 installer and owner guide supplied with the ceramic fuel effect. This
should have been placed inside or attached to this guide by the installer.
Burner.
Remove any deposits of soot or other foreign matter from the 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 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.
FITTING THE LOWER FIREFRONT
Decorative firefront.
Place the decorative firefront on the hearth and
centralise to the appliance.
‘Quattro’ and ‘Anthem’ firefront only
Note:Before removing the ‘Quattro’ / ‘Anthem’
firefront it is necessary to remove the ceramic fuel
effect.

carefully and place aside. We
recommend that the fuel
effect is removed in the
reverse order to that shown
in the fitting sections.
! Remove the lower
‘ashpan’.
! Lift the firefront clear of
the burner.
! To fit the firefront, locate
the firefront as in figure 4.
The hooks should fit into the
slots on the burner tray.

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.
Servicing.
!
In the United Kingdom servicing can be carried out either by a Baxi Fires Division
service engineer or a CORGI registered installer.
