Replacing Important Components - Diamond F15G/M Instructions Pour L'installation, L'emploi Et L'entretien

4.
The unit should be checked at least twice a year. You must check the burners, the ignition, the interignition, the maximum
and minimum settings and the air inlet.
For any repairs, consult exclusively an authorised assistance centre and ask for original spare parts.
Before carrying out the disassembling of components and their replacement, shut off the gas valve.
Open the door and remove the front panel.
Pull out the oil collecting tray, then proceed to replace the most important components:
A) Piezoelectric Igniter
- Detach the high-voltage wire from the igniter
- Unscrew the screw located under the switch-on button by means of a cross screw-driver (Fig. 9)
- Replace the igniter
- Mount everything back by following the reverse order sequence.
B) Pilot spark-plug "Ignition Ramp" (Fig. 6 position 5)
- Remove the high-voltage cable
- Unscrew the two screws (Fig. 6 position 8) using a 8mm-spanner
- Replace the spark-plug
- Mount everything back by following the reverse order sequence.
C) Thermocouple (Fig. 6 position 4)
- Unscrew the nut (Fig. 6 Pos. 9) with a 10 mm wrench and remove the thermocouple.
- With a 9mm-spanner, unscrew the thermocouple from the safety valve (Fig. 10)
- Mount everything back by following the reverse order.
D) Pilot burner "Ignition Ramp" (Fig. 6 position 6)
- Remove the gas connection by using a 10mm-spanner (Fig. 6 position 2).
- Disconnect the high-voltage wire.
- Undo the two screws (Fig. 6 position 1)
- Remove the spark-plug (Fig. 6 position 1) and the thermocouple (Fig. 6 position 4).
- Change the pilot assembly (Fig. 6 position 6).
- Mount everything back by following the reverse order.
ATTENTION : Check the gas seal with soap bubbles.
E) Thermostat valve
- Remove the bulb from the bushing (Fig. 8 pos. 1)
- Remove the gas pipe from the valve outlet
- Undo the 4 screws of the upper gas inlet flange
ATTENTION : Carefully check the O.R. gas seal.
- Remove the thermocouple with a 9mm-spanner.
- Remove the pilot burner gas supply pipe by using a 10mm-spanner.
- Change the old thermostat valve with a new one.
ATTENTION : The buttons must be
- Mount everything back by following the reverse order.
- Adjust the bypass idle screw (100% open !)
- Mount back the valve pipe and the limit thermostat bulb.
ATTENTION : Check the gas seal with soap bubbles.
Check that the oil temperature reaches 195°C with the thermostat on position 8.
F) Burner (Fig. 5)
- Unscrew the nut (Fig. 5 pos. E)
- Unscrew the upper nut on the plate by using an 13mm-spanner.
- Unscrew the screw on the plate by using an 10mm-spanner.
Now you can replace the burner.
- Mount everything back by following the reverse order.
ATTENTION : Check the gas seal with soap bubbles.
G) Safety thermostat (Fig. 10)
- Check the operation and find the reason causing the thermostat to come on. Its replacement is very easy.
ATTENTION : The thermostat interrupts the thermocouple circuit.
