59 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 and side tie rods. Tighten the nuts and screw. Ensure that the sealing gasket is compressed.

3.Refit the fan, fan electrical connections, the thermostat electrical connections, the red pressure sensing pipe, the blue CO/CO2 sensing pipe and the two fan fixing screws.

4.Refit the air box assembly and burner. Ensure that the burner front fixing is refitted.

5.Refit the combustion chamber, (replacing the rope seal if necessary) ensuring the two rubber sealing grommets are replaced.

6.Reconnect the gas supply and the electrical wiring. Refer to Frames 36 & 41.

7.Check the sightglass in the boiler casing. Clean or renew as necessary. Refer to Frame 62.

8.Check for gas soundness. Check the gas service cock and pressure test point.

9.Refit the boiler casing (refer to Frame 49). Note that it is not necessary to disturb the controls casing pod.

10.Close the controls pod door.

60 GAS PRESSURE ADJUSTMENT

PILOT

The pilot is factory set to maximum and no further adjustment is possible. If, after removing and checking the injector (as detailed in Frame 67) and ensuring that there is an inlet pressure of 20 mbar available, the pilot does not light then contact Ideal Stelrad Group.

Relight in accordance with 'Initial Lighting', Frame 48.

MAIN BURNER

After any servicing, reference should be made to Table 2 which quotes details of the rated output with the related burner setting pressure and the heat input. Any required adjustments should be made by using the pressure adjustment screw.

Refer to 'initial Lighting', Frame 48.

REPLACEMENT OF PARTS

61 GENERAL

When replacing any component:

1.Isolate the electricity supply.

2.Turn OFF the gas supply.

3.Remove the boiler front panel. Refer to Frame 53.

IMPORTANT. When work is complete the casing must be correctly refitted, ensuring that a good seal is made.

Note. In order to assist fault finding, the control box printed circuit board is fitted with 2 indicator lights which represent the following boiler conditions:

Neon I3. Mains electricity ON.

Neon SG1. Flashes to indicate ignition operation (stops after detection).

The boiler MUST NOT be operated if the casing is not fitted.

62 SIGHTGLASS REPLACEMENT

1.Refer to Frame 61.

2.Unfasten the 2 nuts and washers holding the sightglass assembly to the casing front panel.

3.When fixing the new assembly ensure that the parts are in the correct order. The frame must have the return edge at the bottom.

4.Retighten the 2 nuts to ensure an airtight seal. Do NOT overtighten.

5.Replace the boiler front panel. Refer to Frame 49 .
