Injectors

Remove the burner caps and heads. Remove the old jets

the 2 cross-headed screws hidden behind the handrail end
brackets (Fig.8-2) and remove the 3 fixing screws underneath
the control panel (Fig.8-3).
The control panel will drop down slightly. It is held at the top

the tags on the inner panel. Lift the control panel clear of the
tags and pull forwards, taking care not to damage or strain the
wiring.
