SETTING PRESSURE (continued)

If the setting pressure is too low, but the meter pressure is acceptable, then a problem in the supply pipework is to be suspected. This will be

dirt and debris, kinked or inadequate size pipes, restriction in a fitting or solder flashing across a joint. (NOTE: you will not get an accurate

reading of the inlet pressure with a pressure gauge on the end of the supply pipe - this is the static pressure in the system. You must use a T

piece and measure the supply pressure with the fire on High - the dynamic pressure). Refit and tighten the screw into the pressure test point

when the test is complete.

FLUE SPILLAGE MONITORING SYSTEM

This fire is fitted with a flue spillage safety device (ODS). If the fire shuts down during use for no apparent reason then several things may be

suspected. If a door or window has been opened creating a draught, then pilot disturbance is the problem, and removal of the draught should

resolve this. The gas pressure reaching the fire must also be checked (again, recall your installer to check and rectify any problem). The ther-

mocouple connection into the back of the gas control valve may also have worked loose during installation, simply get the installer to tight-

en. If pilot disturbance is not the cause, then the ODS safety system may be in operation. Switch the appliance OFF, check the flue and carry

out any remedial work required. Relight the fire and carry out a spillage test. DO NOT allow the appliance to be used if it continues to fail a

spillage test.

The aeration hole of the pilot must be carefully cleaned out on each annual service to ensure continued function of the ODS.

The spillage monitoring system shall not be adjusted, modified, or put out of operation by the installer. Any spare parts fitted MUST be of a

type supplied for the purpose by the appliance manufacturer. If the fire is not spilling, then further guidance should be sought, using the

Troubleshooting section as a guide.

TESTING FOR SPILLAGE

Close all doors and windows to the room containing the appliance. Let the fire run on HIGH for five minutes. Take a smoke match, light it,

and using a smoke match tube, hold it at the top edge of the fire opening, 25mm down and 25mm in. Starting 50mm in from either side, run

the smoke match across the opening. All the smoke should be drawn away up the flue. Any smoke returning into the room indicates that

spillage is occurring. If the initial spillage test fails, run the fire for a further 10 minutes and repeat the test. When the test has been complet-

ed satisfactorily, repeat with any extractor fans in the premises running on the highest setting, and any communicating doors open. Finally,

repeat with all doors open. DO NOT allow the fire to be used until the test is satisfactorily passed.

BRIEFING THE CUSTOMER

All instructions must be handed to the user for safekeeping. Show the customer how to light and control the fire.

After commissioning the appliance, the customer should be instructed on the safe use of the appliance and the need for regular servicing.

Frequency of service depends on usage, but MUST be carried out at least once annually. Advise that cleaning of the fire may be achieved

when the fire is cold using a damp cloth and mild detergent on most surfaces.

Scratched and other superficial damage to the matt black paintwork of the appliance can be covered with matching heatproof spray. Use

only the manufacturers’ recommended spray paint. Paint only when the fire is OFF and cold. Always mask off the surrounding area to pre-

vent contamination with overspray. Ventilate the room during the use of the spray. DO NOT attempt to spray paint the coals or ceramics, or

wash them in water.

Advise that the fire will emit a “newness” smell for a time after initial commissioning and that extra ventilation may be needed during this

time. Advise that the fire is fitted with a spillage safety device (O.D.S.). If the fire shuts down, this system may be in operation. If spillage is

suspected, SWITCH APPLIANCE OFF and call in the installer to investigate any problems.

SERVICING

Isolate the fire from the gas supply. Ensure that the fire is fully cold before attempting service. A suggested procedure for servicing is detailed below.

1. Lay out the dust sheet and tools.

2. Carefully remove the ceramic components.

3. Remove the cast front fret, or remove the combined frame and firefront.

4. Remove the two screws that retain the data/control plate. 

5. Disconnect the gas supply, and remove the two securing screws in the tray legs.

6. Remove the burner tray.

7. Remove firebox as described.

8. Check the fireplace opening for rubble accumulation and remove. If debris is excessive, initiate remedial work on the flue.

9. Check the flue with smoke pellet for correct operation.

10. Refit firebox using new seals where necessary.

11. Strip off the burner pipes and clean thoroughly.

SERVICING (continued)

12. Clean out the injector, pilot assembly and burner tube. DO NOT remove the pilot injector.

13. Re-assemble and re-fit the burner tray.

14. Turn on the gas supply, and leak test.

15. Refit the decorative casting and ceramics.

16. Check any purpose provided ventilation is un-obstructed.

17. Light the fire and test for spillage.

18. Check setting pressure and safe operation of the appliance.

For specific servicing instructions, see the relevant sections.

CLEANING THE CERAMIC PARTS

Remove the firefront and place to one side. Remove the ceramic components. Gently clean in the open air. Be careful not to create dust

from the ceramics. Where necessary replace damaged components with genuine spares. Seal scrap ceramic components in plastic bags

and dispose at proper refuse sites as directed.

Re-fit the ceramics by referring to the relevant section of these instructions.

REMOVING THE BURNER TRAY

Remove the decorative front. Remove the ceramics and the data/control plate and place safely aside.

Remove the two screws securing the tray legs to the firebox. Pull tray forward slightly and lift away.

Refitting is the reverse of above, being sure to engage the tray location lugs on the shelf at the rear of the firebox.

DISMANTLING THE BURNER TRAY

Remove the tray as previously described. 

The pilot unit can be removed by withdrawing the tubing nut, the thermocouple nut on the rear of the valve, and the two securing screws,

and lifting away. Remove the tubing nut from the valve end of the pilot pipe, and blow through to dislodge any debris. 

Remove the two tubing nuts on the ends of the gas pipe to the injector elbow and blow clear. Release the screw through the  supporting leg

and lift assembly clear. The injector pipe can now be checked for debris. Remove the nut retaining the injector elbow. Blow through the elbow

to remove any debris.

The valve is not field serviceable, apart from the pilot filter. Remove the control knob by pulling it forwards, then remove the largest of the

three screws on the face of the valve. Slide the filter out and clean away any debris that may have accumulated. The filter element should also

be blown clean. This component should not require replacement, however if signs of deterioration are evident then a genuine spare part must

be used. If a large amount of debris is present in the filter then the pipework and control should be thoroughly cleaned before re-assembly.

PILOT ASSEMBLY

Remove the burner tray as in relevant section and pilot unit as described.

Clean the pilot assembly with a soft brush and blow through. Check the aeration holes are free of any dirt or lint. Clean thoroughly internal-

ly, the connection can be removed from the base of the pilot unit using two spanners to make cleaning easier. Do not damage or try to

remove the pilot injector. The unit is factory set and the only check necessary is to ensure the spark gap is correct. See specifications for

gap setting.

REMOVING THE FIREBOX

Remove the burner tray as described previously.

Protect the hearth from potential damage. Unroll the coiled tensioner cables from the rear of the firebox. Remove the securing nipples and

tensioner adjusters. The firebox is now released from the opening and can be slid outward onto the hearth. Inspect the fireplace opening

for debris and if excessive rectify the flue before proceeding further. Check the seal around the fireframe and if necessary replace. Refitting

of the firebox is as described in the fitting section of these instructions.
