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).

1. Light the boiler and carry out a pre-service check, noting any
operational faults.
2. Check the flue terminal (and terminal guard if fitted) is undamaged
and clear of any obstruction.
3. 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.

components the boiler front panel must be removed. Refer to
Frame 50.
1. Clean the main burner. Refer to Frame 47.
2. Clean the heat exchanger & condensate trap/siphon. Refer to
Frames 50 & 51.
3. Check the main injector for blockage or damage. Refer to Frame

4. Check that the flue terminal is unobstructed and that the flue
system is sealed correctly.
The cleaning procedures are covered more fully in Frames 45-52 and
MUST be carried out in sequence.

Please n ote: 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

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
