will be able to download the relevant information.

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).

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

manufacturer’s 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.

VICING

Note

. In order to carry out either servicing or replacement of components

the boiler front panel must be removed. Refer to Section 3.2.

PRELIMINARY INSPECTION

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

operational faults (refer to appropriate fault finding chart as

necessary).

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

and clear of any obstruction.

Check combustion by connecting the flue gas analyser to the flue

gas sampling point as shown in the diagram and measure CO and

at maximum rate. To set the boiler to Maximum and Minimum

heat inputs see page 66. Repeat at minimum rate.

If the CO / CO

ratio is greater than 0.004 please proceed to

“Cleaning Procedure”.

If the CO / CO

ratio is less than 0.004 please proceed to “Check

Procedure”.

CHECK PROCEDURE

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.

Proceed to “IMPORTANT”.

CLEANING PROCEDURE

Clean the main burner. Refer to Section 3.4.

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

Section 3.5 & 3.6.

Check the main injector for blockage or damage. Refer to Section 3.3.

The cleaning procedures are covered more fully in Sections 3.3 - 3.6

and MUST be carried out in sequence.

For cleaning of the Ideal System Filter please refer to section 3.21.

Proceed to “IMPORTANT”.

Do not operate the boiler if the front panel is not fitted.

IMPORTANT

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

ensure the trap is refilled with water before re-assembling.

After completing the servicing or exchange of components always

ensure all gas valve connections are gas tight with a gas soundness

check up to the gas control valve.

When work is complete the front panel MUST be correctly refitted,

ensuring that a good seal is made.

Clean the Ideal system filter, refer to system filter installation and

maintenance guide for correct method of servicing.

Complete the service section in the Benchmark Commissioning

Checklist.
