7.3 CLEANING THE BOILER
1. Remove any deposits from heat exchanger using a suitable soft brush. Do not use a brush with metallic bristles.
2. Check the condition of the combustion chamber insulation panels. Any damaged panels must be replaced. (Refer to
Component Replacement, section 8.23).
3. Check the condition of the burner injectors on the manifold, carefully clean them with a soft brush if necessary.
Do not use a brush with metallic bristles as this might damage the injectors.
4. Remove any fallen deposits from the bottom of the inner case.
5. Unscrew and replace any injector that appears damaged.
6. Clean the top of the burner with a soft brush and check that the flame ports are clear. Blockages may be removed with a
stiffer brush. Tap the burner, open end down, to remove any deposits from inside.
7. Check the condition of the electrodes.
9. Check the spark gap, positioning and height of the electrodes (see Fig. 18).
10. Check that the fan impeller is clean and free to rotate.
7.4 RE-ASSEMBLE THE BOILER
1. Replace the burner, ensuring it is located correctly and secure it in position using the four screws previously removed.
2. Replace the combustion chamber front cover, ensuring it is correctly located.
3. Ensure the electrode leads are connected and the seals are in position in the bottom of the inner case.
4. Test the connections for gas soundness and check the burner pressures. (Refer to Commissioning, sections 5.4 and 5.5).
5. Ensure that the room sealed chamber panel seal is intact and in position, replace the panel ensuring it has been located
correctly (especially on the sides) and secure it in position with the screws previously removed.
6. Place the front case panel in position as shown in Fig. 17 and secure in position.
7. Raise the control panel and secure in position with the two screws provided.
8. Check the operation of the boiler. (Refer to Boiler Operation, section 6).

Check the operation of the boiler. (Refer to Boiler Operation, section 6).
Ensure that all the controls are returned to their original settings.
The replacement of components in sections 8.3 to 8.13 does not require draining of the boiler.
8.1 GENERAL ACCESS - Fig. 17
Ensure the electrical supply is isolated and the gas supply is off.
1. If access is required behind the control panel - Release the two fixing screws (one each side) securing the control panel
and lower the panel.
2. To gain access behind the casing - Lift the case front panel upwards slightly and pull it forwards to remove it from the boiler
(see Fig. 18). If required, remove the side panels by removing the bottom fixing screw and lifting forwards and upward.
3. To gain access to the combustion chamber - Remove the four screws securing the room sealed chamber panel and
remove the panel, taking care not to damage the seal.
Note: When replacing the panel, ensure the seal is intact and that the panel has been located correctly, especially on the sides.
4. To gain access to the control panel components - Remove the five screws securing the rear cover and carefully raise
the cover from the front. When replacing the cover, ensure no wires are trapped and all wiring is secured. Secure with five
screws - do not overtighten.
