into its servicing position.

After replacing ANY component check operation of the

boiler, including gas soundness, gas rate and combustion

test.

IMpORTaNT.

When work is complete, the front panel must be correctly

refitted - ensuring that a good seal is made.

Notes.

In order to assist fault finding, the control panel has

an LED diagnostic display.

The key to boiler fault

conditions is shown in Frame 63

2. In order to replace components in Frames 54-61 it is

necessary to drain the boiler. Refer to Frame 53.

42 FaN REpLaCEMENT

Refer to Frame 41.

Disconnect the electrical leads from the fan.

Undo the gas pipe union connection to the

injector housing.

Remove the extended nut retaining the fan

mounting bracket.

Lift and remove the fan and venturi assembly.

Remove the screw and twist venturi anti-

clockwise to remove venturi assembly,

noting

the orientation of the venturi in relation to the

fan body.

Transfer the venturi assembly to the new fan,

replacing the ‘o’ ring if evidence of damage or

deterioration is visible.

Fit the new fan / venturi assembly ensuring the

retaining tabs are correctly positioned and the

fan outlet sealing gasket is correctly positioned

and free from damage. Refit the extended nut.

Reassemble the boiler in reverse order, taking

care not to overtighten the screw on the fan
