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.

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 is 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.

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 removed.

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, which 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 Figs 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.

The lower front panel assembly is removed by lifting upwards and pulling forwards. Remove the canopy to gain access to the Bezel or (Goal post trim) securing screws. The canopy is held in position by dimpled spring clips on both the side flanges, remove by exerting an even pull forward. See Fig 11.

Remove the outer bezel/Goal post trim by unscrewing the four M4 taptite screws on the inner flanges and the four No 8 self tapping screws in the corners.

It will be necessary to dismantle the burner from the convector box before installing the box in the opening, to remove the burner, unscrew the two screws securing the fibre back/ side cheek assembly in position and remove, remove the coal support shelf and burner inserts. Unscrew the two screws at the base of the aperture in the fascia panel and withdraw the burner.

With the gas supply pipe laid to the required position and the surround fitted and sealed to the chimney correctly – this is to prevent any seepage of the flue products and to prevent any ingress of air into the flue from anywhere other than the flue outlet of the fire. The method to be used to secure the appliance in position is either screwed directly onto the front face of the back panel through the mounting brackets or fixed to the internal side walls of the builders opening using the four fixing brackets provided. These can be rotated to accommodate most openings, as shown in Fig 14: plastic plugs and wood screws are supplied for these brackets.

It is very important when fitting the trim, that when it is secured in position, that the rear of the trim has an effective seal with the back panel or fixing wall. ( A seal is fitted to the trim during manufacture).

Continue the supply and replace the burner ensuring that the rear legs locate in the two up-formed tags in the base plate and complete the gas connection to the burner. Replace the canopy.

NOTE: Before offering the convector box into the opening, the hearth should be protected from damage or scratches that may occur during installation.

The complete installation should be tested for Gas soundness.

IT IS VERY IMPORTANT THAT THE RESTRICTOR PLATES ARE REMOVED AND THE SCREWS REPLACED WHEN THE APPLIANCE IS INSTALLED INTO EITHER A PRE-CAST OR A 5in (125mm) DIAMETER FLUE.

Turn on the Gas supply at the meter and to the appliance at the isolating cock. Purge the air to the appliance. Rotate the control knob to the ignition position, depress the control and push the piezo to ignite the pilot. Check that the electrode is sparking between the tip of the thermocouple and continue until a pilot ignition is established. Depress the control knob slightly and rotate anti-clockwise until the index symbol is aligned with the small flame symbol on the indicator label, release and rotate the control knob to the high position (large flame symbol). Check that the flame picture is satisfactory prior to carrying out the spillage test.

To check the gas pressure at the appliance, allow the coals and the coal bed to cool and turn off the gas supply at the isolating cock. Remove the hexagon headed screw and connect a manometer to the pressure test point, turn on the gas and ignite the fire, allow to heat up and check that the gas pressure is 20 +/- 1 mbar - any appreciable drop may indicate losses through the pipework. The pressure test point may also be used to check for leakage of the joints to the appliance. Allow the coal bed to cool before replacing the screw.

Turn the gas control to the OFF position, wait for 90 seconds, fully depress the gas control, turn to the ignition position and release the control. Attempt to light the pilot with an already prepared match or taper. If the pilot lights the FSD is faulty.

Light the appliance and set to the maximum setting, locate the front and fret in position and leave to warm up for approx. 5 minutes. Check for satisfactory clearance of combustion products by inserting a lighted smoke match on a vertical plane 30mm down, 10mm inside the rear edge of the inner canopy and 70mm from the left hand side of the opening. All the smoke must be drawn into the flue. If spillage occurs, allow a further 10 minutes. Should spillage still occur, examine the chimney for the fault and rectify. The test should be carried out with all windows and doors closed, if an extractor fan is situated in the room, this test should be repeated with the fan running. If there is a connected room with an extractor fan, the test should be repeated with all the doors to that room opened and the extractor fan running.

Demonstrate the lighting and extinguishing procedures to the user.

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 is 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. To ensure that the release of fibres from these RCF articles is kept to a minimum, during installation and servicing we recommend that you use a HEPA filtered vacuum to remove any dust and soot accumulated in and around the fire before and after working on the fire. When replacing these articles we recommend that the replaced items are not broken up, but are sealed within heavy duty polythene bags, clearly labelled as RCF waste. This is not classified as "hazardous waste" and may be disposed of at a tipping site licensed for the disposal of industrial waste. Protective clothing is not required when handling these articles, but we recommend you follow the normal hygiene rules of not smoking, eating or drinking in the work area and always wash your hands before eating or drinking. Any sooty deposit on the thermocouple probe can be cleaned off using a non-fluffy cloth. DO NOT USE ABRASIVE MATERIALS

TURN OFF THE GAS SUPPLY TO THE APPLIANCE. Remove coals, coal supports, burner inserts, front simulated coal and fibre back/side cheek assembly. To gain access to components below the burner assembly it has to be removed from the vent box case by disconnecting the gas supply at the inlet elbow and unscrewing the two screws at the base of the facia panel.

I.TO CLEAN OR REPLACE THE INJECTOR: Unscrew the compression nut connecting the gas supply to the elbow injector while supporting the injector. This is to prevent distortion of the framework, unscrew and remove the gas supply tube from the gas control valve, hold the injector lock nut with a spanner and rotate the injector. Replace in reverse order.

II.TO REPLACE THE GAS CONTROL (Tap/FSD): Disconnect the three gas pipes and the thermocouple from the control. Pull off the knob and lay to one side. Undo the retaining nut at the front of the tap niting assembly to withdraw control from the mounting bracket. Replace in reverse order.

III.TO REPLACE THE PIEZO IGNITER: Pull off the HT lead from the rear of the igniter, prevent the metal fixing nut from turning, rotate the body of the igniter to unscrew and withdraw the igniter from the front. Replace in reverse order and reconnect the HT lead.

IV.

TO REPLACE THE OXY-PILOT ASSEMBLY: The operation of the oxy-pilot depends on the proximity of

 

the spark electrode and the thermocouple tip, if either of these components are defective the assembly must be

 

replaced. This is achieved by removing the tube nut from the base of the pilot and the thermocouple from the

 

FSD also the igniter lead and the two M4 screws securing the bracket to the framework. Replace in reverse
