Description

This Royal Cozy Fires Decorative 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 (using the optional spacer frame) where the warmth and comfort of an open fire with high radiant heat is required. This appliance is intended for decorative purposes and the coal bed uses ceramic simulated (coals) to give a realistic appearance and to allow secondary air to be entrained into the bed to ensure clean combustion. An aerated single ported steel burner is used running parallel across the front of the fire. A combined gas control and piezo igniter with a variable high to low setting is used, this is fitted with a Flame Supervision Device (FSD). This is 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. The Piezo igniter is used to ignite an Oxy-Pilot sensor (ODS) which will cause the appliance to (shut off) in the event of continued spillage occurring under hazardous or blocked flue conditions. The fire bed consists of ceramic fibre components and coals all of that are removable for cleaning purposes when required. It is important when relaying the coal-bed and coals to follow the instructions correctly.

This appliance is suitable for installations into the following flues: 7" minimum diameter flues (CLASS 1)

5" minimum diameter flues (CLASS 2),

Pre-cast flues to BS 1289 Pt 1 1986 (when spacer frame is fitted).

The installations must always be used in conjunction with a suitable hearth and surround (refer to page 5 for further details).

Important Notes

A hearth must always be provided to project forwards of the brass trim a minimum of 300mm and a minimum of 150mm either side of the fire opening. The hearth must be a minimum thickness of 12mm with a perimeter height of 50mm 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.

The appliance is fitted with an ODS, a spillage monitoring system which operates if the evacuation of products is interrupted (i.e. blocked or incorrect flueing). If the gas fire repeatedly ‘goes out’ it may indicate a problem and the installer or specialist should be informed before further use.

Areas of this appliance will become hot after prolonged running and it is recommended that for the protection of the very young, elderly and infirm a fireguard conforming to BS 6539 or BS 6778 be used.

Care should be taken to prevent any damage being caused to surrounding soft furnishings or decor e.g. many embossed vinyl wall coverings may become discoloured if located close to the appliance. Clearances required for combustible shelves are shown in page 3.

Care should be taken to ensure that when the appliance is installed into a Pre-cast flue, the chimneybreast is lined to prevent the plaster etc. cracking through excessive temperatures.

In most installations a back panel will be required, this will also need a minimum fire resistance rating of Class O (100 O C).

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.

A range of fronts and frets are available for use with this appliance, these have perforated frets to allow air to be drawn into the coal bed for combustion and over the controls for cooling purposes. If other fronts and frets are to be used they must have a minimum open area in the fret of 20sq cms and 60sq cms in the front. See Fig. 11.

The chimney or flue (unless new) must be swept before installation. It should be checked annually for satisfactory clearance of products and that there is no excessive build up of soot.

TO LIGHT THE APPLIANCE

1.Remove the Fret (Controls cover), to gain access to the controls.

2.Press and turn the gas control anti-clockwise, keep the control fully depressed. The igniter will operate and the pilot will light, if not repeat the operation.

Page 2

3.0nce a pilot-flame has been established; keep the control depressed for a further 20 seconds. Release the gas control and check that the pilot remains lit.

4.Depress the gas control slightly and turn anti-clockwise until the indicator mark is aligned with the letters HIGH. The burner will cross light from the pilot.

5.Depress the gas control slightly and turn anti-clockwise until the indictor mark is aligned with the letters LOW. The burner will now be at minimum rate.

6.To turn ‘off ‘ the appliance, return the control to the ‘OFF’ position.

7.If for any reason the fire cuts out, return the control knob to the `OFF’ position and wait 3 minutes before re-lighting.

8.In the event of failure of the igniter the fire may be lit by placing a lighted taper or match at the pilot position at the same time depressing the gas control in the IGN position.

Removal of Debris or Soot Deposits

Debris from any source or any soot formed shall require removal. 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. 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.

Laying the Coal Bed

The coal support shelf is positioned on the fibre support metalwork, ensure that the shelf sits against the two stops which are to prevent the shelf sitting on the burner outlet. Place the simulated coal front in position as shown in Fig.6, three tabs are provided to locate. The one-piece coal support shelf is constructed to allow three levels of coal support; these three levels are shown in Fig 7, the plan view of the bed.

.

Coal Layout (See Figs 6 - 9) (6 Large and 12 small)

First Layer. Position 3 large coals and 6 small coals between the front simulated coal and the lower level of the coal support shelf. Ensure the gap indicated is left clear to view the pilot flame.

Place 3 large coals on the middle level of the coal support shelf as shown.

Second Layer. Place 4 small coals in position to fill gaps between the coals on the lower and middle level of the coal support shelf

Place 2 small coals in position to straddle the 3 large coals on the middle level and upper level of the coal support shelf..

NOTE: Additional coals must not be used. If any of the coals or coal bed become damaged, lost or broken, replacements must be obtained (part numbers listed in short spares list) before the appliance is used.

VENTILATION

Additional purpose built ventilation is not required for this appliance in GB only, for IE ventilation is required with a minimal cross section area of 100sq cms, it should be checked regularly to ensure that it is free obstruction

Clearance to Side (Timber Surrounds etc.)

Minimum clearance required to any combustible material to the side of the appliance must be 150mm

Clearance to Shelves

Minimum clearance to the underside of a 150mm deep combustible shelf from the hearth must be 790mm. Add 12.5mm to this clearance for every 25mm increase in depth of shelf.

The list of coal part numbers that the user can replace is at the back of this document.

This appliance is intended for decorative purposes.

Installing the Appliance

Check that the chimney and flue structure are sound and conform to the following flue requirements.

a)A conventional brick or stone chimney with a minimum effective cross sectional dimension of 225 x 225mm. A lined flue with a minimum diameter of 175mm having a chairbrick and throat forming lintel conforming to BS 1251 or a builders opening (constructed of non-combustible material) measuring 540mm high x 400mm wide with a sufficient depth for debris collection. If a chairbrick is fitted, a minimum depth requirement for the fire with the spacer frame fitted is shown in Fig 1, if a spacer frame is not used, the chairbrick will have to be removed.

b)A twin walled metal flue box manufactured to BS 715 with a twin walled 125mm diameter flue and a minimum effective height of 5 metres. See page 12.

c)A pre-cast flue conforming to the requirements of BS 1289 Pt. 1 1986 and BS 1289 l975 including properly constructed pre-cast flues with a cross sectional area of 13000sq mm.

Important

Dampers, register plates or incorrect flue terminals, must not restrict the above listed flues. 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 restrictor shall be removed or fixed in the fully opened position.

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 that may cause spillage to occur.

Installation using a 5” Diameter Metal Flue Box

Important: The spigot restrictor marked ’B’ must be fitted. See page 7.

When the metal flue box is to be built-in as a false chimneybreast using the timber studwork with 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.

Installation of the Appliance

Check that the chimney conforms to the required specifications as previously stated. Examine the condition and carry out any remedial work 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.

GAS SUPPLY

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 combined pressure test/ restrictor elbow situated on the R/H side of the burner. Provision is made i.e. knockout blanks for entry into the box in both L & R hand rear corners and at the L & R hand sides. Any pipe used under the tray must be in rigid tube such as bundy, A suitable piece of bundy is included in the fitting kit to assist the installer..

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. It shall be constructed to prevent passage of gas either between the pipe and sleeve or sleeve and wall.

Where a gas supply pipe enters the box in any of the positions stated, the hole around the pipe should be sealed with a silicone sealant or similar to prevent Ingress of air into the flue. Permanent sealant e.g. fire cement etc should not be used as these would prevent removal of the firebox.

Dismantling the fire Prior to Installing

It will be necessary to dismantle the burner from the firebox before installing the box in the opening.

To remove the burner from the box unscrew the two screws at the base of the fascia panel and lift the assembly approximately 200mm at the front to clear the fixing flange. When refitting observe that the two feet at the rear of the assembly locate under the two lugs formed in the base of the box assembly.

If the installation has either a 5in (125mm.) or 7in (175mm) flue if will be necessary to select the appropriate restrictor, (See page 7). To insert the correct restrictor plate remove the centre screw securing the fibre retaining strip in position and slacken off the two outer screws to allow the two slots in the restrictor plate to slide behind the two screw heads and replace the centre screw and tighten the outer screws.

Important

THE RESTRICTOR PLATE 'A' AND 'B' (marked 1 dimple/2 dimples) MUST NOT BE USED WITH PRE-CAST FLUES.

The restrictor ‘A’ marked with 1 dimple is for use with 7in (175mm) diameter flues and the restrictor ‘B’ marked with 2 dimples is for use with 5in (125mm) diameter flues.

The appliance is supplied without any Flue Restrictor fitted in position i.e. suitable for pre-cast flues.

The correct fitting of the restrictor plate is carried out prior to installation. See Fig 4. Two self-tap screws are provided to hold the restrictor in position. The single dimple is uppermost for the ‘A’ position and the double dimple uppermost for the ‘B’ position.
