Prepare the Boiler

The controls cover should have been removed when
unpacking the boiler, if not remove controls cover by
opening the door covering the securing screw on the
underside of the controls cover, see Fig. 14. Undo
securing screw, pull controls cover forward 10 mm,
lower to release from the four side fixings and pull
forward clear of the thermostat knob.

Remove door by undoing the two lower fixing screws
and lift door off the two upper hinge brackets.

Remove the screws securing the combustion chamber
front panel and remove panel.

Disconnect the fan supply leads from the connector
adjacent to the fan. Leaving in place the three screws
identified with a red circle or adjacent ‘F’ mark in fan
plate. Remove the remaining screws securing the fan
mounting plate and remove the mounting plate
complete with fan.

Disconnect the two flexible tubes from the flue elbow.
Remove the four brass securing nuts and lift off the
flue elbow, taking care not to damage the gasket.

Note: If side fluing, loosen the two brass securing
nuts beneath the flue elbow outlet and remove the
other two. Tilt the flange and withdraw the elbow.

The boiler is supplied with the flue outlet sealing plate
removed on one side. If another flue outlet direction is
required, remove the appropriate flue outlet sealing plate
and transfer it to the left hand position.
