WARNING.

Always turn

OFF

the gas supply at the gas service cock, and switch OFF and disconnect the electricity

supply to the appliance before servicing.
Combustion testing must be carried out by a competent person using a combustion analyser conforming to BS7927.

To ensure the continued safe and efficient operation of the appliance it is recommended that it is checked at regular intervals and

serviced as necessary. The frequency of servicing will depend upon the installation condition and usage but should be carried out

at least annually.
It is the law that any service work must be carried out by a Gas Safe Registered Engineer. In IE service work must be carried out

by a Registered Gas Installer (RGII).

INSPECTION

Light the boiler and carry out a pre-service check, noting any

operational faults.

Check the flue terminal (and terminal guard if fitted) is

undamaged and clear of any obstruction.

Check all water and gas joints for signs of leakage. Remake

any suspect joints ensuring a gas tightness check is carried

out if applicable and the water system is correctly refilled,

vented and re-pressurised.

CLEANING PROCEDURE

Note.

In order to carry out either servicing or replacement of

components the boiler front panel must be removed.

Refer to Frame 37.

Clean the main burner. Refer to Frame 39.

Clean the heat exchanger & condensate trap/siphon. Refer to

Frames 40 & 41.

Check the main injector for blockage or damage. Refer to

Frame 45.

Check that the flue terminal is unobstructed and that the flue

system is sealed correctly.

ALSO IF THE DHW FLOW RATE IS IN QUESTION :-

Check the DHW filter for blockage. Refer to Frame 66.

The cleaning procedures are covered more fully in Frames 38-42

and MUST be carried out in sequence.

IMPORTANT.
6.

After completing the servicing or exchange of components

always test for gas tightness.

When work is complete the front panel MUST be correctly

refitted, ensuring that a good seal is made.

Do NOT OPERATE the boiler if the front panel is

not fitted.

If, for any reason, the condensate trap/siphon has been

removed ensure the trap is refilled with water before

reassembling.

Check the gas consumption.

10.

Check combustion by connecting the flue gas analyser to the

flue gas sampling point as shown in the diagram and measure

CO & CO

If the CO/CO

ratio is greater than 0.004 AND the integrity of

the complete flue system and combustion circuit seals have

been verified and the inlet gas pressure (and gas rate) have

been verified, then contact Technical Helpline.

11.

Complete the service section in the Benchmark

Commissioning Checklist.

Flue Sampling Point

Air Sample

Point

Ensure all caps and seals

are re-fitted after use

GENERAL

Please Note

: During routine servicing, and after any

maintenance or change of part of the combustion

circuit, the following must be checked:

- The integrity of the flue system and the flue seals,

- The integrity of the boiler combustion circuit and

the relevant seals

- The operational (working) gas inlet pressure at

maximum rate.

- The gas rate
- The combustion performance.

COMPETENCE TO CARRY OUT THE CHECK

OF COMBUSTION PERFORMANCE

Please Note

BS 6798:2009 Specification for

installation and maintenance of gas-fired boilers of

rated input not exceeding 70kW net advises that:
- The person carrying out a combustion

measurement should 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, and

- 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 BS7967, Parts 1

to 4.
