7.2 Main Burner Bars/Injectors
7.2.1
Remove the burner tray as in 7.1.
7.2.2
To remove the burner bars first remove the screws securing the retaining bar at the front end of the
burner and pull off the retaining bar (see Fig.7.1).
Remove the screws securing the burner rear baffle and pull it upwards to remove.
7.2.3
The individual bars may now be removed by pulling up the front end clear of the mounting tray and
then pulling the burner forward off its injector.
Note: The burners are all the same except the first burner on left from the front (see Fig 7.1). This
burner has no cross lighting bracket and has two mounting tongues to prevent incorrect assembly.
It will be found easier to remove burners starting from the opposite end of the burner tray.
7.2.4
If the injectors are being removed they are now accessible, each one is screwed into its port of the
manifold with a soft metal sealing washer and may be removed using a 13mm spanner.
7.2.5
On replacing injectors ensure that they seat onto the soft metal washer to effect a tight seal and that
the correct one is fitted for gas being burned. See marking stamped onto the injector and tables in
Section 2. It is recommended that new sealing washers are used when replacing injectors to ensure
a gas tight seal.
7.2.6
When refitting the burner bars start by fitting the No 1 burner (without cross lighting bracket) and
ensure that the burner is pushed fully home against the injector and then pushed down to the bottom
of its mounting slots.
Repeat for each burner in turn until all the burners are back in place.
Replace the rear burner baffle ensuring that it engages into the slot in the bottom of each burner tube
inlet bracket.
Finally replace the retaining bar and its fixing screws.
