COMMISSIONING : GENERAL
Safety
it is essential that commissioning shall be undertaken only by suitable qualified personnel. In
the case of MDFL burners, commissioning engineers should be experienced in
commissioning forced draught oil and gas burners.
In the UK, it is a legal requirement that anyone working on gas installations, as defined in the
“Gas Safety (Installation and Use) Regulations 1994”, is CORGI registered.
Nu-way can accept no responsibility for consequential loss, damage or injury which results
from a failure to follow the commissioning instructions provided or from commissioning
procedures being undertaken by unqualified personnel.
In an Emergency
MDFL burners are designed and constructed to meet all essential requirements of the Gas
Appliance Directive 90/396/EEC.
When used in accordance with the instructions provided, MDFL burners are unlikely to
produce a hazardous condition. If. however, such a condition should arise in connection with
the burner, the appliance or any instrument, machine or service in the vicinity of the burner,
the FUEL AND ELECTRICITY SUPPLIES SHALL BE ISOLATED IMMEDIATELY and they shall
remain isolated until the fault has been identified and rectified.
Inspection
Before commissioning begins it is important to:
1. Check that the electrical wiring is complete and complies with all applicable Codes and
Standards.
2. Ensure that the fuses are fitted and of the correct ratings.
3. Check electrical earthing.
4. Verify that the gas and oil supply pipework is correctly sized and it has been checked for
leakage.
5. Ensure that the manual gas isolation valve at the inlet to the gas train and the ball valve on the
oil line are operable, fully closed and leak tight.
6. Make all personnel involved in the commissioning aware of the location of the emergency gas,
oil and electricity isolation points.
7. Check that fittings such as purge and test points are available.
8. Establish that the application is in an appropriate and safe condition to be fired, for example,
that there is water in the boiler.
9. Set the appliance controls to call for heat. Check the appliance’s ventilation and flueing
arrangements.
10. Ensure that any warning notices appropriate to the commissioning procedure are in position.
11. Ensure that all necessary tools and test equipment are available and ready for use. Essential
items include a manometer or other approved pressure measuring equipment, means (which
may be permanently installed or provided specifically for commissioning) of measuring flow
rates of oil and gas, equipment for checking the smoke number of the flue products and a
means of analysing the flue products for carbon dioxide (CO
2
), oxygen (O
2
), and carbon
monoxide (CO).
