FLUE FAN & MIXER (Fig. 74)

Unclip and remove the air chamber front and the right hand side covers. Slacken the gas pipe (A) at the air box connection and swing/rotate away from the fan assembly. To remove the mixer

(B)locate and remove the three screws (C). To remove the fan

(D), disconnect the electrical connections attached to the fan, locate and remove the four screws (E). Gently ease the fan from its location.

Replace in the reverse order. Ensure all seals are in good condition, taking care to ensure they are replaced correctly.

BURNER (Fig. 75)

Unclip and remove the air chamber front and the right hand side covers. Slacken the gas pipe (A) at the air box connection and swing/rotate of the fan assembly. Locate and remove the 3 internal nuts (B) which secure the fan assembly in position (C) to the heat exchanger (D). Disconnect the electrode leads and ancillary wiring from their respective connectors. Remove the retaining screws (A fig. 73) for sensing electrode and remove. Remove the retaining nut (C fig. 73) for condensation sensor (D fig. 73) and remove. Gently ease the fan assembly out of its location. Once the assembly has been removed, the burner (E) can be withdrawn from the heat engine. Ensure the seal (F) is in good condition, taking care to ensure it is replaced correctly. Replace in the reverse order.

BLOCKED FLUE PRESSURE SWITCH/IGNITION TRANSFORMER (Fig. 73)

Disconnect the compensation pipe (G).

Disconnect the electric wiring from the pressure switch/ignition transformer.

Remove the two screw (F) on the upper part of the combustion chamber.

Remove the screw (I).

MAIN HEAT EXCHANGER (Fig. 76-77)

Unclip and remove the three air chamber covers (front, left hand, right hand sides). Disconnect all the wiring connections.

Fig. 76: slacken the gas pipe (A) at the air box connection and swing/rotate of the fan assembly. Disconnect the flow (B), return

(C)and condensation connections on the heat exchanger. Locate and remove the 4-screws that secure the heat exchanger to the combustion chamber (D). Move the heat exchanger to the right and disconnect it from the flue collector (E). The heat exchanger can now be lifted up and removed from the boiler.

Fig. 77: to remove the fan burner assembly (A) locate and remove the 3 external nuts (B). Replace in the reverse order. Ensure all seals are in good condition, taking care to ensure they are replaced correctly.

AUTOMATIC BYPASS (Fig. 78)

Disconnect and remove the flow pipe (1), at the connection to the pressure relief valve, at heating manifold and at the connection to the air chamber. Using a hooked piece of wire, carefully withdraw the bypass cartridge (2).

Ensure all seals are in good condition, taking care to ensure they are replaced correctly. Replace in the reverse order ensuring the cartridge is facing the correct way.
