To replace the thermocouple disconnect the quick connect fitting and the earth ring from the
gas valve. The bracket retaining the thermocouple is secured to the burner mounting bracket.
The thermocouple head and threaded body is retained in the thermocouple bracket via two
locking nuts one above and one below the bracket. Remove the top locking nut and remove the
thermocouple. Replace the thermocouple in reverse order. Note the bulb is positioned relative
to the burner port and secured by two 8.0mm (across the flats) x 2.5mm thick hex nuts. The nut
under the bracket is the datum for aligning the bulb tip with the burner port. The top nut secures
onto the upper surface of the bracket. On the replacement thermocouple ensure that the
thermocouple tip is relative to the inner burner port – 6.3 mm above burner port, 3.7 mm
between thermocouple and port, 34.6 mm from top surface of mounting bracket to tip of
thermocouple.
Ensure the appliance is tested for gas leakage after servicing.
