13 .1

Annual Servicing

Case Front Panel

1. For reasons of safety and economy, it is recommended that

 

the boiler is serviced annually. Servicing must be performed by

 

a competent person in accordance with B.S. 7967-4.

 

2. After servicing, complete the relevant Service Interval Record

 

section of the Benchmark Commissioning Checklist at the rear

 

of this publication.

IMPORTANT: During routine servicing, and after any maintenance or change of part of the combustion circuit, the following must be checked:-

• The integrity of the complete flue system and the flue seals.

• The integrity of the boiler combustion circuit and relevant seals as described in Section 13.2.

• The operational gas inlet pressure as described in Section 11.2.1 to 11.2.7 and the gas rate as described in 11.2.8.

• The combustion performance as described in ‘Check the Combustion Performance’ (13.1.4 to 13.1.6 below).

B.S. 6798 ‘Specification for Installation & Maintenance of Gas

 

 

Fired Boilers not exceeding 70kW’ advises that:-

 

Facia Panel Securing

•

The person carrying out a combustion measurement should

 

Screws

 

 

have been assessed as competent in the use of a flue gas

 

 

 

 

 

 

analyser and the interpretation of the results.

 

 

•

The flue gas analyser used should be one meeting the

 

 

 

requirements of BS7927 or BS-EN50379-3 and be calibrated

 

 

 

in accordance with the analyser manufacturers’ requirements.

 

 

•

Competence can be demonstrated by satisfactory

 

 

 

completion of the CPA1 ACS assessment, which covers the

 

 

 

use of electronic portable combustion gas analysers in

 

 

 

accordance with BS 7967, Parts 1 to 4.

 

 

Check the Combustion Performance (CO/CO2 ratio)

 

 

4. Set the boiler to operate at maximum rate as described in

 

 

Section 15.1.1 to 15.1.6.

 

 

5. Remove the plug from the flue sampling point, insert the

 

 

analyser probe and obtain the CO/CO2 ratio. This must be

 

 

less than 0.004.

 

 

6. If the combustion reading (CO/CO2 ratio) is greater than

 

 

this, and the integrity of the complete flue system and

 

 

combustion circuit seals has been verified, and the inlet gas

 

 

pressure and gas rate are satisfactory either:

 

 

• Perform the ‘Annual Servicing - Inspection’ (Section 13.2) &

 

 

 

re-check

 

 

• Adjust the gas valve (Section 15.0) & re-check

 

 

• Replace the gas valve (Section 14.23) & re-check

Panel

 

 

1.

Ensure that the boiler is cool.

 

 

2.

Ensure that both the gas and electrical supplies to the

 

boiler are isolated.

 

3.

Slacken the screws securing the facia panel. Lift the outercase

 

panel so that its securing tabs are clear of the facia. Remove the

 

panel, allowing the facia to hinge down (Fig. 69).

 

4.

Remove the screws securing the inner door panel. Lift the

 

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

 

(Fig. 70).

 

 

Sump

 

 

 

5.

Unscrew the sump from the bottom of the condensate trap

 

assembly (Fig. 71) and remove any deposits from the sump and

 

trap. Clean as necessary and replace the sump.
