and the upper lid C upwards (on and RM77 remove the plate D, Fig. 63).

Remove the fibre glass insulation around the heater so that the heater is accessible
for removal. Then bend aside the wire clip keeping the heater in proper position,
disconnect the heater leads from the cord and iemove the heater.

Make sure the new heater is fully inserted before bending back the wire clip (with
caution, or it might snap off), Reset the electric connections. Be careful to put
the Pibre glass insulation back in its proper place and in such a way that the heater
leads will not be in direct contact with hot boiler tubes.
It is essential that the remplacement heater be of the proper rating in order to
provide the correct heat input for the particular model.
