6.2 Service operation
Burner head
The burner head should be examined carefully for cracks and/or damage. If there are signs that there has been
over heating of the material or dust on the burner face, the burner head must be removed from the burner.
Close examination of the silver foil at the rear of the inside of the burner head should be done and if all is
okay, the inside of the Inverterjet burner head should be blown out using compressed air.
If the inside of the burner head is found to be severely blocked with dust and dirt please examine
the burner material more closely. It is likely that the burner head material will have overheated due
to the blockage and will be blackened in appearance and may need replacing. If so, the customer
must be advised to protect the burner from dust ingress and/or increase the service intervals.
Electrodes
Inspect the ignition and flame electrodes, if extensive signs of damage are detected, they must then
be removed and replaced.
Fan
The fan is not a serviceable component. Simply ensure it is positively secured and sealed. The
gasket material, electrical plug connections and cover must be secure and in good condition.
The fan case has gas tight seals and the fan casing must never be opened. Due to the 1:1 gas/ air
ratio operating principle of the burner a reduction in fan performance (i.e. dust build up) will not
result in unsafe burner performance.
The gas flow is directly proportional to the air flow therefore any reduction in fan flow would simply
result in a gradual reduction of the appliance heat input.
Venturi Unit
Examine and clean the Venturi unit checking that it is securely attached, and that any gasket is in
good condition. Ensure that any Air Pressure Sensing point is secure and unobstructed (if fitted).
Cleaning: Using a cloth, soft brush and vacuum, carefully remove any dust and grime from the
whole burner assembly taking care not to disturb electrical connections.
6.2.1 Re-assembly
Using a new replacement gasket, carefully and securely slide it to the burner head up until the
gasket and the mounting plate are in contact. carefully refit the burner system into the appliance
combustion chamber and secure using the fixings.
Re-connect gas and electrical connections.
Check for gas soundness as detailed by Local, National Standards and Regulation
s and turn ‘ON’
the Gas and Electrical supplies.
Finally check and record the combustion and ventilation performance of the burner. Check the basic
operation/control of appliance before restoring automatic control to any Boiler Management System
(if applicable).
