Burley G4121 mk2 Oxygen Depletion Pilot System, Instructing the Customer, Servicing Instructions

15.Oxygen Depletion Pilot System

There is a highly sensitive oxygen depletion sensor designed into the pilot light. If any part is damaged the entire unit must be replaced using only genuine spare parts as similar looking parts from other appliances may well give inferior performance. If the fire repeatedly trips off in operation the oxygen depletion system may be operating and a qualified engineer should investigate this.

16.Instructing the Customer

The installer should instruct the customer on the operation of the appliance and handover all instruction leaflets.

The customer must be made aware of the need for regular servicing of the appliance, this will normally be once a year.

The customer should also be made aware that no rubbish should be thrown into the firebed and that purpose provided ventilation should be checked regularly.

17.Servicing Instructions

Before commencing any servicing, ensure that the gas is isolated and the appliance is cool.

Cleaning – The casing should be wiped with a cloth dampened in soapy water. The glass may be cleaned with any non-abrasive cleaner such as ‘hob brite‘.

The coals contain refractory fibre (RCF). Excessive exposure to these materials may cause temporary irritation to the eyes, skin and respiratory tract; consequently, it makes sense to take care when handling these parts to ensure that the release of dust is kept to a minimum. We recommend the use of a HEPA filtered vacuum to remove any dust and soot accumulated in the heater before and after working on it. When replacing these articles, they should not be broken up, but sealed in heavy duty polythene bags labelled RCF Waste’, which may be disposed of at a tipping site licensed for industrial waste. Protective clothing is not required, but normal hygiene rules of no smoking, eating or drinking in the work area should be followed.

Controls – The system for monitoring the oxygen supply to the burner is not adjustable and must not be put out of operation. Should the oxypilot system need to be replaced, the original manufacturer’s parts must be used.

Injectors – Only original manufacturer’s injectors must be used.

The unit must be serviced at least once per year, preferably at the beginning of the heating season. All servicing must be carried out by a qualified service person. A combustion analysis check should be carried out using an analyser to BS7967 and sampling the entire width of the combustion product outlet. Ratio of CO/CO2 should be less than 0.002 within 30 minutes. (20ppm CO per 1% CO2) A reading of CO in the room centre should give a rise of less than 9ppm over ambient, peak reading.

Light the fire using the method in the instructions and ensure that the pilot lights consistently and the pilot flame envelopes the thermocouple evenly, it is located at the front on the right-hand side.

The pilot should hold in 6-10 seconds. Turn control to main burner, this should light smoothly within 10 seconds. Ensure the valve gives adequate turn down and the thermostat bulb reduces the burner rate to off when heated.

Locate thermostat bulb in a cool place off the appliance and preferably outside of any inglenooks, to ensure it is sensing room air temperature.

Run the appliance for 10 minutes, ensuring burner flames settle evenly.

The gas manifold pressures are factory pre-set using highly accurate equipment, and must not be altered. The catalyst is unlikely to need replacement during the life of the heater. The appliance should be inspected before use and at least annually by an authorised service person. More frequent cleaning may be required due to accumulation of lint and dust from carpeting etc.
