damage or deterioration. If there are any signs of damage the full pilot assembly will need replacing.
Replace if necessary.
NOTE -
There is a highly sensitive oxygen depletion sensor designed into the pilot assembly. If any part
of the assembly is damaged the
entire unit must be replaced. Do not attempt to bend or alter the
flame head, thermocouple or aeration hole. Use only genuine spare parts as similar looking parts from
other appliances may well give different or inferior performance and could lead to a hazard.
Check the condition of the spark ignition lead ensuring both ends are securely connected.
Replace if
necessary.
Check that all wiring and plug connections to the control unit, gas valve motor, battery, remote sensor
and control switches are secure and in good condition.
Check that the thermostat bulb is correctly located and the coil is not kinked or damaged.
Replace if
necessary.
Re-assemble all removed components in reverse order and carry out a commissioning procedure as
detailed in section
Burley Appliances recommend the following on an annual basis.
Check for combustion product leakage -
It is important that the products of combustion produced by
this appliance all pass through the two catalysts. A very small amount of product leakage is acceptable
providing safety can be confidently assured when the appliance is operational.
To check for leakage, remove the decorative grill and glass screen and check box construction and glass
fitting for visible gaps / signs of leakage. The appliance is not pressurised therefore small
manufacturing gaps are permissible and these will have been measured in the factory.
If the manufactured assembly is suspect contact your supplier.
Emission of combustion products -
If available a combustion analyser to BS 7967 should be used to
sample the combustion products exiting from the appliance grill outlet into the room. The appliance
should be switched on and allowed to warm for 20 minutes. A sample should be gathered across the
entire width of the grill. A CO/CO2 ratio of less than 0.002 should be measured at all times irrespective
of the length of time the appliance has been operating. A sample taken in the centre of the room shall
indicate that the CO content is no more than 9 ppm above ambient.
