1. Remove the burner unit in accordance with Chap. 6:1.
NOTE! Inlet gas pipes do not always need to be remo-
ved, but if necessary must be pushed to the side to gain
access to the screws. The bulb and overheating protec-
tion do not need to be removed. This saves both time
and unnecessary work.
Carefully press the burner unit down and fold out at the
upper edge far enough to allow the pilot burner and
spark plug to be seen.
. Slacken the nut (fig 21 C) on the spark plug and
unscrew. Pull down the spark plug, nut and cable with
silicone sleeve and take them out at the side. Remove
the plug from the cable and nut, and destroy it imme
-
diately by bending the electrode so that it cannot be
confused with a new plug.
. Fit the nut to the new plug and connect the cable. Pull
the silicon sleeve (fig 21 D) over the joint, approximately
5 - 8 mm on to the plug. Insert the spark plug in place
and tighten the nut carefully. Check the distans,
see fig 21.
