IMPORTANT SAFETY NOTICE
This appliance has a ceramic Fire-bed arrangement;
this contains Refractory Ceramic Fibres, which are
man-made vitreous silicate fibres. Excessive expo-
sure to these materials can cause irritation to eyes,
skin and respiratory organs. Hence we recommend
that when handling these materials the release of
dust should be kept to a minimum. During installa-
tion and servicing we recommend that a HEPA fil-
tered vacuum be used to remove any dust and soot
in and around the fire. If any of the ceramic fire-bed
components need to be replaced we recommend
that the removed parts be sealed in a heavy-duty
polythene bag, and be labelled as RCF waste. RCF is
not“Hazardous waste”and can be disposed of at a
licensed tipping site for the disposal of industrial
waste.
The appliance incorporates an Oxygen Depletion
Sensor (ODS) Monitoring system.This is located on
the front of the burner, and must not be adjusted
by the installer. This ODS system must not be put
out of operation, and if any parts require changing,
only original manufacturer parts shall be used.
This appliance is designed to be used either Natu-
ral or LPG gas however, each individual appliance
is only capable of running off the type of gas speci-
fied at the time of purchase. It is important to note
that once a type of gas has been specified the stove
cannot run off any other type.The type of gas that
your stove is capable of burning is stated on the
data information panel.
This appliance has been designed, tested and ap-
proved to meet standards in place for product use,
performance and safety. Installation of your Stove
must comply with current building regulations. It is
therefore recommend that a CORGI engineer be
employed for this task. Taking particular notice of
“thermal inversion”The engineer will provide you
with information about the safety limits of the in-
stallation and should fix a notice plate in a place
where it can be readily seen.
This appliance is designed as an efficient heating
device and consequently all body parts become
very hot in use. Except for the control knob and con-
trol access door,which are designed to stay cool,all
other parts are working surfaces and should not be
touched.
The glass and frame on this appliance acts as a fire-
guard conforming to BS: 1945 – 1971 and satisfies
the Heating Appliance (Fireguards) regulations
1991. No part of the window or frame should be
permanently removed. It does not give full pro-
tection for young children or the infirm, extra pro-
tection should be considered for these conditions
conforming to BS 6539 or BS 6778.
Bearing in mind that the heat given off by this ap-
pliance may affect articles placed close to it, cur-
tains should not be placed within 30cm.
The appliance is not designed as a dryer. It is not
therefore recommended that the appliance be used
in such a manner. Do not place any articles within
30cm of this appliance as this may result in damage
to the articles.
The installation must be carried out in accordance
with the following regulations:
The Building Regulations issued by the Department
of the Environment, the Building Standards (Scot-
land) (Consolidation) Regulations issued by the
Scottish Development Department.

USERINFORMATION
IT IS VERY IMPORTANT TO READ THESE
INSTRUCTIONS THOROUGHLY BEFORE
LIGHTING.
This appliance will produce an odour and/or smoke
for the first few hours of use when new.Please ven-
tilate the room when first lighting from new.
There is a flue spillage monitoring system fitted to
this appliance, which cuts off the gas supply upon
the detection of spilled flue gasses. If this system
activates and the appliance cuts out, allow 3 min-
utes before retrying the ignition, noting that the
control tap must first be returned to the off posi-
tion. If the pilot will not light, allow a further 3 min-
utes or sufficient time for switch to reset. If cutting
off persists, then a professionally qualified (i.e.
CORGI registered) engineer should be informed.
The controls are located behind the access panel,
which is the swing out panel underneath the main
door. The standard control is a basic rotary tap,
which has a single control knob. As an optional ex-
tra a remote control version is available which has
two rotary control knobs. The remote control ver-
sion must be specified at time of ordering
All versions of this appliance operate with a tradi-
tional pilot light.The pilot light is located in the cen-
tre of the burner, and is visible through the front
window. If the Flame Supervision Device Actuat-
ing Flame (the Pilot Light) is extinguished either by
intention or not, no attempt should be made to re-
light until 3 minutes have elapsed.
IMPORTANT: Immediately after lighting,the ap-
pliance must be left on HIGH for ten minutes in
order to warm up the chimney.

REMOTE CONTROL ELECTRONIC
IGNITION SYSTEM
Igniting the Appliance.
Simultaneously press
the“ OFF”and“K”but-
tons of the receiver for
ignition.
An acoustic signal indi-
cates that the start se-
quence has begun.
The electronic system
then checks that the
main gas is flowing and
ignites the main burner; this may take up to 20 sec-
onds.
(NOTE: During start-up, override knob cannot be
in Manual position.)
Adjusting the Heat Setting
You are now able to use the remote control.To in-
crease the flame, the top button (K) should be de-

set will reduce the flame.
It is also possible to turn the main burner all the
way down so that it is effectively off, leaving only
the pilot ignited.
Extinguishing the Appliance Fully
From any heat setting,press the“ OFF”button for
a few seconds. This will cause the burner to fully
extinguish.
The system has a safety interlock which will not al-
low the Ignition until the Interlock rests (this may
take a few minutes).

INSTALLER INFORMATION
INSTALLATION OF THE STOVE
This appliance must be installed by a qualified
CORGI gas engineer, and must be installed in ac-
cordance with the Regulations and Standards listed
in the front of this Manual.
Failure to comply with the instructions in this
manual, or the regulations and standards will re-
sult in the Guarantee being void and could have
hazardous consequences.
Flue Requirements
The flue, which the appliance is to be attached, must
conform to BS 5440 pt.1, and may be either a class 1
or class 2 chimney.Before the appliance is installed,
the flue system or chimney must be inspected and
passed as suitable.
This stove is suitable for installation onto either flex-
ible or fabricated steel flue system and is also suit-
able for pre-cast flues, pre-cast chimney block, pre-
cast flue block and ridge tile vent.
The minimum effective height of the flue must be
three metres measured from the hearth to the ter-
mination of the flue. If the flue has any non-vertical
sections, the height should be increased in line with
BS 5440 pt.1. Prior to installation, the installer should
ensure that the flue is free from obstruction, ideally
should be swept and subsequently smoke tested.
Ensure that any dampers are fixed in a permanently
open position.
The appliance has been designed with a built in
draught diverter, and as such no further draught
diverter need be fitted to the flue system.
Flue Options
This stove is equipped with an interchangeable flue
system,so that it can be fitted either as Rear or Top
Flue,however,the stove is delivered ready to use as
a Top Flue appliance.
If the stove is to be fitted and used as a rear flue
appliance, then the following procedure must be
followed.
1. Break out and remove the curved external cover
plate in the rear of the appliance.
2. Remove the blanking plate from the rear of the
stove and the flue connector from the top of the
stove.
3. Reinstall the flue connector in the rear of the stove
and the blanking plate in the top of the stove.
Stove Location
The stove must stand on a fireproof hearth, which
must be of a non-combustible material which must
extend 50mm in front of the stove.
The hearth must not be capable of inadvertent cov-
ering by a rug or carpet. This may be achieved by
either the hearth being 50mm above the level of
the floor, or a fender or kerb around the hearth to a
height of 50mm.
The appliance must not be fitted against a rear wall
constructed from a combustible material; a gap of
300mm should be given all round the stove before
combustible materials may be used in the wall con-
struction.
If the appliance has to be located in an opening,
the minimum clearance from non-combustible
materials is shown in the figure below.
