3.1 ASSEMBLY OF THE INTERNAL CYLINDER RETURN PIPE TO THE BOILER

Use the packaging as protection, turn the boiler on its left hand side to enable fitting of the hot water return pipe.

BMove the control panel into the service position by removing the screw from the retaining bracket.

1. Loosen the two retaining screws to free the back clamping plate on the hydraulic block as shown in figure 3.

2. Remove the brass bung assembly from the hydraulic block by removing the screw and sliding it free from the flange

on the clamping plate. Make sure that the other brass bung assembly is retained in place.

3. Remove the copper pipe from the Optional Integral Diverter Valve Kit and feed the flat end of the pipe through the

rear of the boiler as shown.

4. Before fitting the pipe, check that the seal is in position on the plastic moulding. Slide the flat end of the pipe under

the flange on the hydraulic block clamping plate ensuring that pipe is located correctly.

5. Secure the clamping plate by re-tightening the two screws (1) loosened in step 1.
