COMMISSIONING
IMPORTANT – SAFETY
It is essential that commissioning shall be undertaken only by suitably qualified and experienced personnel.
In the case of MOL modulating burners, commissioning engineers should be experienced in pressure jet oil
burner commissioning. Nu-way can accept no responsibility for consequential loss, damage or personal
injury which results from a failure to follow the commissioning instructions provided or from
commissioning procedures being undertaken by unqualified personnel.
EMERGENCY INSTRUCTIONS
MOL modulating burners are designed and constructed to meet current legislation. When used in
accordance with the instructions provided, MOL modulating burners are unlikely to produce a hazardous
condition. If, however, such a condition should arise in connection with the burner, the appliance or of
any instrument, machine or service in the vicinity of the burner,
the OIL AND ELECTRICITY SUPPLIES
SHALL BE ISOLATED IMMEDIATELY
and they shall remain isolated until the fault has been identified and
rectified.
Inspection
Before commissioning is begun it is important to:
Check that the electrical wiring is complete and complies with all applicable Codes and Standards.
Ensure that the fuses are fitted and are of the correct rating.
Check electrical earthing.
Verify that the oil supply system is correctly designed and that the supply pipework is correctly sized and
free from leaks.
Ensure that all manual fuel isolation valves are operable, fully closed and leak tight.
Make all personnel involved in the commissioning aware of the location of the emergency fuel and
electricity isolation points.
Check that fittings for bleed and pressure testing are fitted.
Establish that the appliance is in an appropriate and safe condition to be fired: for example, that there is
water in the boiler.
Set the appliance’s ventilation and flueing arrangements.
Ensure that any warning notices appropriate to the commissioning procedure are in position.
Ensure that all tools and test equipment are available and ready for use. Essential items include
temperature measuring instruments for measuring flue gas and appliance water temperatures, and a
means of analysing the flue products for carbon dioxide (CO
2
), oxygen (O
2
), carbon monoxide (CO) and
smoke.
Check that all relevant documentation is available including, where appropriate:
- The agreed plant performance specifications
- Plant drawings and pipework diagrams
- Certificates confirming satisfactory completion of procedures such as soundness testing and
electrical safety tests.
- Commissioning, operating and maintenance instructions for the plant.
Establish that the operation of plant other than that being commissioned will not have an adverse effect
on the operation of the plant to be commissioned and similarly, that the operation of the plant to be
commissioned will not have an adverse effect on other plant.
Confirm that the operation of adjacent plant and machinery will not constitute a hazard to the
personnel involved in commissioning.
