Installation & Servicing

SERVICING

9. Remove all loose deposits from the heat exchanger,

particularly between the fins, using a suitable brush.

10. Reassemble in reverse order, ensuring the fan leads

and 3 sensing tubes are reconnected.

54 REASSEMBLY

Reassemble the boiler in the following order.

1. Refit the flue baffles.

2. Inspect the collector hood rope gasket and replace, if

necessary, ensuring that the self adhesive rope is fitted
centrally on to the lip of the collector hood / fan
assembly. The boiler efficiency will be adversely affected
if incorrectly fitted. Refit the collector hood and retain
with the 2 front tie rods and the rear central fixing screw.
Tighten the nuts and screw. Ensure that the sealing
gasket is compressed. Refit the pressure pipe.

3. Refit the positive pressure tubes on the top of the fan

housing. Reconnect the electrical leads.

4. Refit the air box assembly and burner. Ensure that the

burner front fixing is refitted.

5. Reconnect the gas supply and the electrical wiring.

Refer to Frames 36 & 38.

6. Check the sightglass in the boiler casing. Clean or

renew as necessary. Refer to Frame 57.

7. Check for gas soundness. Check the gas service cock

and pressure test point.

8. Refit the boiler casing (refer to Frame 46). Note that it is

not necessary to disturb the controls casing pod.

9. Close the controls pod door.

1. Remove the 2 silicon rubber tubes from the fan sensing

points.

2. Disconnect the fan leads.

3a. Rear flue

Slacken the M4 screw securing the flue connector to the
fan. Disconnect the connector from the fan and slide into
the flue.

3b. Side or top flue

Slacken off two M4 screws securing the flue elbow and
flue connector. Disconnect the flue connector from the
elbow and slide into the flue. Remove the flue elbow.

4. Disconnect the silicon rubber tube from the rear of the

collector hood.

5. Slacken the two M5 nuts on the front tie rods, releasing the

tie rods from the combustion chamber.

6. Remove the M5 central fixing screw at the rear of the

collector hood and remove collector hood/fan assembly.

7. Check that the fan impeller runs freely. Remove any debris

from the impeller with  a soft brush.

8. Remove the flue baffles.

52 CLEANING THE FAN ASSEMBLY / THE FLUEWAYS

53 CLEANING THE BURNER AND PILOT ASSEMBLY

1. Brush off any deposits that may have fallen on to the

burner head (ensuring the flame ports are unobstructed)
and remove any debris that may have collected.
Note. 

Brushes with metallic bristles must not be used.

2. Remove the main burner injector and ensure there is no

blockage or damage. Clean or renew as necessary.

3. Refit the injector, using an approved jointing compound

sparingly.

4. Inspect the pilot burner and ignition / detection electrode.

Ensure that they are clean and in good condition.

Check that:

a. The pilot burner injector is not blocked or damaged.

Refer to Frame 61 for removal details.

b. The pilot burner is clean and unobstructed.

c. The ignition / detection electrode is clean and

undamaged.

d. The ignition / detection lead is in good condition.

e. The spark gap is correct (refer to Frame 61) Clean or

renew as necessary.

Note. 

The pilot shield is located around the pilot assembly

bracket and is located by the electrode retaining nut.
