Maintenance 10

10.2 Standard Inspection and Maintenance

Operation

When performing any inspection or maintenance

personal protective equipment must be used where

appropriate.

1. Ensure that the boiler is cool and that both the gas and

electrical supplies to the boiler are isolated.

2. Remove the screws securing the case front panel. Lift the

panel slightly to disengage it from the tabs on top of the case

(Fig. 43). Hinge down the control box.

3. To aid access disconnect the igniter plug & disconnect the

two pipes from the top of the condensate trap and the drain pipe

from the trap outlet. Undo the screw & washer securing the trap

to the boiler lower panel.

4. Disengage the lip on the trap from the slotted bracket and

remove the trap. Take care not to spill any residual condensate

on the controls and P.C.B. Thoroughly rinse the trap and

examine the gasket on the trap base, replacing if necessary.

5. Remove the clip securing the gas feed pipe to the air/gas

venturi. Disconnect the pipe. Do not break the joint between the

pipe and gas valve unless necessary.

6. Note their position and disconnect the electrode leads and

the fan electrical plugs (Fig. 46).

7. Undo the four 10mm nuts retaining the combustion box cover

to the heat exchanger.

8. Carefully draw the fan, collector and cover assembly forward

(Fig. 46).

9. Clean any debris from the heat exchanger and check that the

gaps between the coils are clear.

10. Inspect the burner, electrodes position (Fig. 45) and

insulation, cleaning or replacing if necessary. Clean any dirt or

dust from the boiler.

11. Carefully examine all seals, insulation & gaskets, replacing

as necessary. Look for any evidence of leaks or corrosion, and

if found determine & rectify the cause.

12. Prime the trap and reconnect the pipes to the top.

Reassemble in reverse order.
