9. Remove the right hand boiler casing panel (viewed from the
burner end). This panel is xed in place by:
• Two screws in the right end of the upper rear panel.
• Four screws along the lower outer edge of the side panel.
• Two screws at the right end of the control panel.
Note: It will be necessary to support the control panel when
the side panel is removed.
10. Slacken the compression nut at the base of the ow connection
pipe (on the right hand side of the boiler). Carefully rotate the
ow pipe through 180° until it faces to the front of the boiler, then
re-tighten the compression nut.
11. Push the 28 mm push-t connector (supplied with the boiler)
onto the end of the boiler ow pipe.
12. Fit the pressure relief valve onto the manifold pipe, then push
the manifold pipe end into the 28 mm push-t elbow on the
ow pipe. Refer to Figure 7-9.
13. Remove the two screws securing the motor to the pump body.
Rotate the motor through 180°, then replace and secure with the
two screws. Fit both 28 mm pump valves to the pump using the
sealing washers supplied.
14. Fit the pump assembly to the air vent/pressure relief valve
assembly ensuring that the pump shaft is horizontal and the
pump motor is facing towards the rear of the boiler. The ow
arrow on the body of the pump must face in the direction of ow
away from the boiler connection.
15. Fit the pressure relief valve discharge pipe to the pressure
relief valve using the nut and olive supplied. Route the
discharge pipe through the slot in the base of the right hand
side panel. Push the panel insulation back to expose the slot.
16. The circulating pump may be wired into the boiler control
panel if required. Refer to Section 8.
17. Ret the casing side panel only after lling and checking the
system for leaks
Ensure there is no leak from the connection at the base of the ow
pipe BEFORE re-tting the casing side panel.

2. Remove the ½” BSP black iron plug from the front of the boiler
waterway, using a 3/8” drive socket wrench.
3. Fit the ½” BSP straight end of the exible expansion vessel hose
to the tapping on the front of the waterway using a suitable thread
sealant.
4. Remove the nuts and washers from the boiler combustion
door.
5. Fit the vessel support bracket to the studs of the combustion
door and ret the nuts and washers. Tighten to ensure an
adequate seal is made.
6. Position the 16 litre expansion vessel onto the support bracket
in front of the boiler combustion door locating the top of the
vessel behind the control panel rst.
7. Screw in the locking screw on the base of the bracket to
