5.3 Replacing parts
All parts must be replaced by authorized technicians
only!
To replace the following parts first remove all the control knobs and
control panel (after loosening the fixing screws), then extract the
ignition wire.
5.3.1 Gas valve
Loosen the fitting of the pipe (pos. 3,16,17 and 21 fig. 1) of the gas
that are used to connect the gas pipes and the thermocouple,
unscrew the O-ring pressing nut and the screw fixing the bulb inside
the tank, take off the thermostat capillary and bulb from their
housings. Install the new piece in reverse order paying attention to
the oil sealing O-rings (we recommend to replace them with new
ones). Once replaced, it is necessary to check the oil seal by filling
the tank and bringing the oil to working temperature and the gas
seal by using a leak detector spray.
5.3.2 Safety termostat
Unscrew the nut inside the tank that fixes the thermostat button
bulb, take the bulb off followed by the seal from the opposite side.
Disconnect the electrical connections and replace the piece refitting
it in the reverse order and paying attention to the oil seal.
5.3.3 Thermocouple
Unscrew the fitting (pos. 17 fig. 1) fixing the thermocouple on the
valve, unscrew the two screws on the pilot burner and replace the
thermocouple (pos. 38 fig. 2) install in reverse order. To make the
operation easier (as well as all those involving the pilot burner), the
screws can be removed (pos. 35 fig. 2) and the pilot burner brought
to a more comfortable position.
5.3.4 Plug
Unfix the cable (pos. 36 fig. 2) from the plug, unscrew the two
screws on the pilot burner and replace the plug (pos. 32 fig. 2)
