BURNER SERVICING
For ease of servicing and access to the burner
components the burner has, on the bottom
face, a keyhole cut-out. This allows the burner
to be hung from the mounting flange in a
more convenient position.
After loosening the fixing bolt the burner can
be extracted from the flange, turned around
and then the keyhole can be located onto the
bolt.
The burner service requires that all of the components are cleaned and
checked for correct operation, or signs of damage. A check must be carried
out on all safety devices i.e. photocell, solenoid valves, etc. The nozzle should
be replaced every 12 months, or sooner if worn or dirty. Filters and fuel lines
must be inspected and replaced if necessary.
Below are a series of diagrams showing the removal of the combustion head
components from the burner. This gives access for the nozzle to be replaced
and the electrodes to be inspected. As shown below the electrode assembly
is to be removed from the nozzle holder before the nozzle is replaced. This will
prevent any accidental damage.
Once the burner has been re-fitted a smoke check and combustion analysis
must be carried out. Once the burner has been commissioned on the
appliance and all settings are correct the figures should then be recorded.
The burner and all other related equipment must be left in a safe and reliable
working order.
