This Royal Cozy Fires Inset Live Fuel Effect gas fire has been developed to give a realistic coal burning appearance
with the instant control and convenience of gas. The fire has been constructed to enable it to be installed into most
applications where the warmth and comfort of an open fire with high radiant and convection heat is required. The
coal bed uses ceramic simulated ‘coals’ and is to give a realistic appearance and to allow secondary air to be
entrained into the bed to ensure clean combustion. An aerated twin ported steel burner is used, running parallel across
the front of the fire combined with a single gas control with a variable high / low setting. This is fitted with a Flame
Supervision Device (FSD) to ensure that should the pilot flame be extinguished for any reason, (including turning off
the appliance), the gas supply to the burner is cut off until a full lighting sequence is repeated. A separate Piezo
igniter is used to ignite an oxy-pilot sensor (ODS), this will cause the appliance to ‘shut off’ in the event of the flame
extinguishing and also in the event of continued spillage occurring under hazardous or blocked flue conditions. The
fire bed consists of ceramic fibre components and coals, all are removable for cleaning purposes when required. It is
important when relaying the coal bed and coals to follow the instructions correctly .

This appliance has been designed and manufactured to the requirements of the British Standards Institution BS 5258
Part 16 1990 and is for use on Natural Gas Only.
All gas appliances must be installed by a competent person in accordance with the current Gas Safety (Installation
and Use) Regulations 1994 (as amended) or the rules in force and in accordance with the manufacturers instructions,
failure to do so could lead to prosecution.
The chimney or flue (unless new) must be swept before installation. It is recommended that the appliance is serviced
annually by a competent person and the flue checked for satisfactory clearance of products and that there is no
excessive build up of soot. The curing effect of heating the coals will cause an initial odour which, although not
harmful, may require additional ventilation until the odour has disappeared.
The appliance has a naked flame, a fireguard conforming to BS 6539 or BS 6778 should be used for the protection of
the very young, elderly and infirm. Combustible materials should not be put on or left in the hearth nor should the
coal bed be used to burn rubbish or other materials.
Care must be taken on the selection of wall coverings within close proximity of the fire as some vinyl and embossed
materials may be become discoloured by convection heat. Soft furnishings must be kept clear from the radiant heat of
the fire and from impinging the hearth area. The hearth must not be covered by any combustible materials such as
carpets etc.
This product uses fuel effect pieces, gaskets and insulation material containing Refractory Ceramic Fibre (RCF),
which are man-made vitreous silicate fibres. Excessive exposure to these materials may cause temporary irritation
to eyes, skin and respiratory tract, consequently, it makes sense to take care when handling these articles to ensure
that the release of dust is kept to a minimum.
This fire will run for 5.4 hours on one therm of gas with the gas control on the high setting.

1. Remove the fret by lifting upwards (controls cover).
2. Press and turn the gas control until the indicator mark is opposite to IGN keeping the control fully depressed.
Press and release the ignition button. Check that the pilot flame has lit at all ports. Keep the gas control
depressed for a further 20 seconds. Release the gas control and check the pilot remains alight.
3. Depress the gas control slightly and turn fully anti-clockwise until the indicator is opposite the small flame
symbol. The burner will now ignite from the pilot assembly and run at the low rate.

Allow the appliance to cool sufficiently before removing all of the coals and firebed components for cleaning
purposes. Once all the ceramics are removed from the firebed check that no debris i s located in the burner slots
(both front and rear). If any debris is present it may easily be removed by using a small piece of thin cardboard to
ease out any foreign matter. Be sure to remove the cardboard after use. Should any soot accumulation become
excessive, the 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, which may blow
dust back into the air. Any sooty deposit on the thermocouple probe can be cleaned off using a non-fluffy cloth.

1. Locate the fibre back/side cheeks in position.
2. Place the coal support shelf on the stainless steel channel, (the machined groove on the underside of the shelf is
located on the rear flange of the channel), two additional location dowels are fitted to prevent the shelf being
incorrectly placed.
3. Place the two shaped burner inserts in channel between the two burner flame ports, (check that a minimum gap of
approx. 6mm is maintained between the rear of the burner insert and the front edge of the coal support shelf).
4. Position the front simulated coal on the shelf provided above the control facia panel.

coals and resting against the rear coals.(fig 22). Finally place the remaining 5 small coals as shown in fig 23. Small
adjustments to the coal layout may be made to give the best visual appearance however, additional coals must
not be used. If any fibre component is lost or broken the appliance must not be used until a replacement is
obtained.

Care should be taken to ensure when the appliance is installed into a Pre-cast flue, the chimney breast is lined to
prevent the plaster etc, cracking through excessive temperatures.
A certain amount of discolouration (blueing) may be seen on the stainless steel combustion chamber, this is normal
due to the temperatures produced in the fire bed.
A hearth must always be provided, a minimum of 340mm and a minimum of 150mm either side of the fire opening
with a minimum thickness of 12mm and a perimeter height of 50mm. This is to deter combustible materials, carpets
etc, being placed on the hearth.
The area under the firebox must have a minimum non-combustible thickness of 25mm.

In most installations a back panel will be required, this will also need a minimum fire resistance rating of Class O
(100 C).
Check that the chimney and flue structure are sound and conform to the following flue requirements:
1. A conventional brick or stone chimneys with a minimum effective cross sectional dimension of 225x225 mm. A
lined flue with a minimum diameter of 175 mm having a chair brick and throat forming lintel conforming to BS
1251 or a builders opening measuring 550 mm high x 400/470 mm wide with a sufficient depth for debris
collection. If a chair brick is fitted, a minimum depth requirement for the appliance is shown in Figs 2 & 3, if
insufficient depth is available, the chair brick will have to be remove d.
2. A twin walled metal flue box manufactured to BS 715 with a twin walled 125 mm diameter flue and a minimum
effective flue height of 3 metres. See Figs 4 & 5.
3. A pre-cast flue conforming to the requirements of BS 1289 Pt 1 1986 and BS 1289 1975 including properly
constructed pre-cast flues with a cross sectional area of 13000sq mm. See Figs 6 - 8.
127(
Dampers, register plates or incorrect flue terminals, must not restrict the flues listed above. The flue must only service
a single appliance and not have any branches or traps that may impede the natural draught. Any flue damper plate or
restrictors shall be removed or fixed in the fully opened positions.
The front and base of the fire opening must be flat and square to ensure a good seal with the appliance; this is to
ensure that there is no reduction in draught through the fire, whic h may cause spillage to occur.

IMPORTANT: Restrictor plates must be removed. See Fig 15.
When the metal flue box is to be built-in as a false chimney-breast using timber stud work with a plasterboard facing,
the metal flue box should be enveloped with insulation material such as Rockwool or similar to prevent a build-up of
heat within the structure. Either an air gap of 75mm should be maintained between any combustible materials and
any part of the metal flue box or a minimum of 25mm of insulation material between the metal flue box and the
combustible material. It is important that both the back panel and the appliance are sealed to the metal flue box to
prevent any leakage of flue products or reduction in the flue draught. See Fig s 4 & 5.

Check that the chimney conforms to the required specifications as previously stated. Examine the condition and
carry out any remedial work as necessary, if the flue has been used for solid fuel it should be swept and a smoke test
carried out to check that satisfactory smoke clearance has been established. If all the smoke is not drawn into the flue,
pre-heat the flue with a blowtorch or similar and re-check. If there is any uncertainty examine for the cause and if
necessary seek expert advice.

BEFORE COMMENCING WORK, TURN OFF ANY APPLIANCES THAT ARE FED BY THE METER
AND ISOLATE THE GAS SUPPLY BY TURNING OFF AT THE METER
The gas connection to this appliance is made with 8mm o/d rigid or semi rigid tube to a pressure test elbow situated
on the L/H side of the burner as shown below. It is advisable to provide a means of isolating the gas supply to the
appliance for servicing with either a restrictor elbow or isolation cock such as shown below. Provision is made in the
rear L Hand corner of the outer casing to allow a gas supply to be fed to the burner assembly. A blanking plate and
gasket is supplied with cutouts and slots that will enable a seal to be made around the supply pipe. If a restrictor
elbow is to be used, it will be necessary to cut and form the bundy pipe supplied. Any pipe used under the burner
must be in rigid tube such as Bundy, 3 pieces of Bundy are included in the fitting kit to assist the installer. (a) A short
piece for use with a restrictor elbow. (b) A formed section for connection to an isolation cock, and (c) a formed
section for R Hand supply using the inline connector supplied. The inlet pipe support bracket can be removed if
necessary to gain greater access, by unscrewing the Control mounting lock nut and lifting over the spindle, as shown
in Fig 9.
Where a concealed gas supply is used, the installer is reminded of the requirements of BS 6891 1988 dealing with
enclosed pipes. The Standard requires that when a gas pipe is fed through a wall, the pipe should be enclosed in a
tight sleeve to protect against failure caused by movement and shall be constructed to prevent passage of gas either
between the pipe and sleeve or sleeve and wall.
Permanent sealant e.g. fire cement etc. should not be used as these would prevent removal of the firebox if so
required.
