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 in figure 1. 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 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

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.

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.

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 fuel effect
bed.
! 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.
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 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 Baxi Fires Division
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 cloth and then dry.
! Do not use abrasive cleaners as these will scratch the fire surface.
! Fascia and firefront - Clean the metal parts with a slightly damp cloth and then
dry. If this does not work apply a very small amount of ‘baby oil’ to a lint free, non-
abrasive cloth and wipe over the surface. Use a clean cloth to wipe off the oil.
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 pieces in the reverse order to
that shown in this guide.
Burner.
! The burner surface can be carefully cleaned to remove any loose particles after
taking off the ceramic fuel effect pieces . Make sure that no particles are pushed into the
burner holes.
CERAMIC COALS INSTALLATION
This section is for models supplied with a ‘Coal’ fuel effect only.
For ‘Pebble fuel effect’ see section headed
‘Ceramic pebble installation’.
The ceramic fuel effect may cause staining /
discolouration to decorative surfaces. It is
therefore advisable to protest decorative
surfaces.
1. Place the base coal in the firebox (See figure
4).
2. Install the fourteen loose overlay ceramic
coals as follows. The smooth surfaces of
the ceramic coals should be at the bottom
and back. Place five of the ceramic coals
along the top of the front base coal (See
figure 5). The ceramic coals should be
evenly spaced. Each ceramic coal can be
rotated to give a random effect. Placing the
ceramic coals with flat sides facing
forward will give a very uniform
appearance.
Important : The front ceramic coals
should not cover the opening slots in the
base ceramic coal. If the opening slots in
the base ceramic coal are covered by more than 2 -3 millimetres a poor flame picture
will result (See figure 6).
A gap is required between the outer left hand ceramic coal and the ceramic coal to its
right. This is for pilot viewing.
3.
Place five loose ceramic coals on top of the first row of ceramic coals. These should
Page 9
OWNER GUIDE

Figure 5. First row of ceramic coals

be evenly spaced. Rest them on the ledges
above the slots in the base coal (See figure 7).
4. Place the remaining four ceramic coals on
top of the base ceramic coal rear (See figure
8).
CERAMIC PEBBLES INSTALLATION
This section is for models supplied with a
‘Pebble’ fuel effect only.
For ‘Coal fuel effect’ see section headed ‘Ceramic
coal installation’.
The ceramic fuel effect may cause staining /
discolouration to decorative surfaces. It is therefore
advisable to protest decorative surfaces.
1. Place the base pebble in the firebox. It should
rest on the ledges at the rear sides of the burner unit
(See figure 9).

follows. The underside of each
pebble is marked with a letter ‘A’ to
‘F’ and an arrow.
2. The pebbles should be positioned
so that the arrows always point
towards the back of the fireplace
opening. When located into position
the stem of each arrow should be at
90° to the rear of the fireplace
opening (See figure 10).
3. Hold pebble ‘A’ upright with the
arrow pointing to the top. Place
pebble “A” on top of the base
pebble (See figure 10).
4. Hold pebble ‘B’ upright with
the arrow pointing to the top.
Place pebble “B” on top of the
base pebble. (See figure 11).
5. Hold pebble ‘C’ upright with
the arrow pointing to the top. Place
pebble “C” on top of the base pebble
(See figure 12).

pebble ‘E’ on top of the base pebble
(See figure14).
8. Hold pebble ‘F’ upright with the
arrow pointing to the top. Place
pebble ‘F' on top of pebble ‘C’. It
should rest against the rear of the
pebble base (See figure 15).
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.
! If you require your fire to be serviced, please contact
Baxi Fires Division Service
on 08706 090 081.
