4. Pull off thermostat knob (C, Fig.11) and knob (D, Fig.11) of safety device (E, Fig. 11).
5. Unscrew union nut (F, Fig.11) of gas-pipe (G, Fig.11) from flame failure safety device (E, Fig. 11).
6. Remove three cable plug-connections from thermostat (H, Fig.11).
7. Unscrew thermo-coupling (I, Fig.11) from thermo-current adapter (J, Fig.11).
8. Unscrew thermostat (H, Fig.11) from support bracket (K, Fig.11) ( 2 screws ).
9. Unscrew two clips (L, Fig.11) from capillary tube (M, Fig.11).
10. Remove gas-equipment from cabinet and dismantle.
11. Dismantling of thermostat (H, Fig.11) : Unscrew flame failure safety device (E, Fig.11) with thermo-current
adapter (J, Fig.11) and the connection (N, Fig.11) from thermostat.
12. Dismantling of the flame failure safety device (E, Fig.11) : Unscrew flame failure safety device from
thermostat (H, Fig.11). Then unscrew thermo current adapter (J, Fig.11) from the flame failure safety device.
13. For reassembly, proceed in the reverse sequence of dismantling.
CAUTION: Coat threaded unions at the connection/thermostat and thermostat/flame failure safety device with
Loctite 572 to ensure good sealing. Be careful not to get any Loctite inside any parts.
5. Replacing the thermo-current adapter (J,Fig. 11).
1. Unscrew thermo-coupling (I, Fig.11) from thermo-current adapter.
2. Unscrew thermo-current adapter from flame failure safety device (E, Fig.11) and replace by new unit.
6. Replacing the thermocouple (I, Fig. 11)
1. Unscrew thermo-coupling from thermo-current adapter (J, Fig. 11).
2. Unscrew clip (0, Fig.11) for gas-pipe (G, Fig.11) and thermocouple.
3. Unscrew the three screws of the mounting plate (A, Fig.12) from the bottom part of gas-burner. Take off
spark ignitor (B, Fig.12), mounting plate with thermocouple (I, Fig.12) and gasket (C, Fig.12).
4. Unscrew lock-nut (D, Fig.12) of the thermocouple
5. Bend new thermocoupling (I, Fig. 11+12) to shape of old one. For reassembly, proceed in the reverse
sequence of dismantling.
IMPORTANT: The gasket (C, Fig.12) between the lower part of the burner and the mounting plate must be
replaced by a new one and carefully positioned to ensure that the burner is properly sealed.
7. Replacement of spark ignitor with cable (B,Fig. 12)
1. Remove ignition cable (P, Fig.11) from piezo ignitor (Q, Fig.11).
2. Unscrew the one screw (A3, Fig.12) from the spark ignitor, withdraw spark ignitor and replace it by a new
one. Reassemble in the reverse order.
