8. REPLACING PARTS
Since specific technical skills are required
to replace the parts listed below, it is
recommended to advise the user to always
contact skilled technical personnel. For safety
and quality reasons, it is recommended to
use original spare parts when replacing
components.
WARNING! All the following operations must
be carried out while the heater is turned off,
disconnecting the gas and electric supplies.
8.1 CONTROL EQUIPMENT
Disconnect the cables by pulling on the terminals
and extracting the connectors, releasing them
first from the special retainer. Replace the
equipment, placing it in the special insert and
attaching it using the self-threading screw. Insert
the terminals and the connectors into their
respective housings
(fig. 24).
8.2 FUSE
Using a special tool, remove the fuse holder on the
power supply terminal board. Replace it with a new
fuse (5x20 -2 Amps - instantaneous type) by
exerting slight pressure until it enters the housing.
Replace the fuse cap in the terminal board.
8.3 GAS SOLENOID VALVES
Disconnect the electric connection on the gas
unit. Remove the two screws that attach the
metal support block of the coils and remove it
from the housing. Pull out the coil(s) from the unit
and replace them with new ones. Replace the
metal support block in the correct position and
tighten the fastening screws. Re-establish the
electrical connection
