7.3.1 Removal of pilot burner
To remove the pilot burner on the DualAir® unit requires the burner tray to be removed as described
in 7.1. However if access is available from below the DualAir® unit then the pilot may be accessed by
removing the bottom panel of the controls section.
i) Remove the bottom panel of the controls section or the burner tray.
ii) Unscrew the pilot gas pipe at its compression fitting with the pilot gas valve.
iii) Unplug the H.T cable from the spark generator.
iv) Unplug the flame probe from its jack socket.
v) Using a 10mm spanner undo the two set screws securing the pilot bracket assembly to the
main burner manifold.
The assembly will now come free by pushing it slightly forward and then allowing it to drop so that it
will pull clear of the main burner.
7.3.2
Using the appropriate spanners undo the flame probe, ignition electrode and gas pipe from the rear
of the ignition burner.
7.3.3
To replace directly reverse the above.
Note: It is important that the correct injector is used and that when assembling the gas pipe to the
pilot burner that the injector is fitted onto the special compression nut so that as the gas pipe is
withdrawn the injector is drawn out of the burner. Failure to fit the injector correctly will cause gas
leaks and permanent damage to the injector.
The Ignition electrode has a small tag connector for connecting the H.T lead and ALWAYS fits into
the centre hole of the pilot burner.
The flame probe (with permanently connected P.T.F.E. insulated wire) is fitted in the end hole of the
pilot burner
7.4 Gas Control Valves
7.4.1
The gas control valves of all heater types are accessible from the controls compartment between the
heater and the fan section without further disassembly .
IT IS MOST IMPORTANT THAT ONLY THE CORRECT GAS VALVES SPECIFIED FOR EACH
MODEL TYPE ARE USED WHEN REPLACING THESE CONTROLS.
