Fig. 26 - 46/58 and 58/70 baffles and turbulators (all models)

15/26, 26/36, 36/46 models - See Section 11.1

1

Combustion head - Loosen the two screws
securing the combustion head and withdraw the
head. Clean and refit the combustion head.

2

Inspect the ignition electrodes - Remove the
combustion head.

Loosen the electrode clamp screw and withdraw
the electrode assembly. Wipe clean and check for
any cracks in the ceramic insulation. Replace if
necessary.

Check the electrode settings

Electrode tips approximately 4 mm apart and 3 to
3.5 mm in front of the nozzle, see Fig 26.

3

Nozzle - The nozzle should be replaced on an
annual service - Check that the nozzle size and type
are correct, refer to table in Section 3.3 and boiler
data label.

With the combustion head removed, loosen the
electrode assembly clamp screw and slide the
electrodes away from the nozzle.

Do NOT attempt to clean the nozzle.

Remove the nozzle using a good fitting spanner
(16 mm). The use of an ill-fitting spanner will
damage the nozzle and could lead to an incorrect
flame pattern. Always check the electrode
settings after replacing the nozzle, see Fig. 27.

46/58 or 58/70 models - See Section 11.2 and Fig. 28

1

Combustion head - Loosen the two screws
securing the combustion head (NOT the screws in
the slotted ring, Fig. 30) and withdraw the head.
Clean and refit the combustion head.

2

Inspect the ignition electrodes - Remove the
combustion head.

Loosen the electrode clamp screw, disconnect the
leads and withdraw the electrode assembly. Wipe
clean and check for any cracks in the ceramic
insulation. Replace if necessary.

3

Check the electrode and diffuser settings - Fig. 29

To adjust the diffuser disc: Loosen the diffuser clamp
screw and slide the disc along the nozzle holder to
achieve the gap 'A' in Fig. 29, tighten the screw.

To adjust the electrodes: Loosen the electrode
clamp screw and move the electrode unit to achieve
the gap 'B' in Fig. 29, tighten the screw.

IMPORTANT: The electrode settings given above
MUST be observed

58/70 shown
