Inspect the burner electrode assembly condition
taking care when reassembling to ensure that the

by bending the earth rod.
Access to the injector is by removal of the screws
that attach the orifice fixing plate to the burner as-
sembly.
To remove the injector with the burner head
removed, unscrew the injector from its carrier
using a spanner on the hexagon portion of its
body.
When replacing the injector ensure that it is fully
tightened in its carrier using an approved thread
sealant. Replace the sealing gasket if this is
not in good condition.

replaced and the injector carrier re-fitted using an
approved pipe joining compound.
