Inspection (cont..)
12. Check that all relevant documentation is available, including, where appropriate:
- The agreed plant performance specification
- Plant drawings and pipework layouts
- Certificates confirming satisfactory completion of procedures such as soundness
testing, purging and electrical safety tests.
- Commissioning, operating, emergency shutdown and maintenance instructions for the plant.
13. 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.
14. Confirm that the operation of adjacent plant and machinery will not constitute a hazard to the
personnel involved in commissioning.
Initial Settings
To prepare the burner for commissioning on oil and gas:
1. Remove the cover from the air damper motor and check the cam positions referring
to the appropriate diagram shown on page 13 or 14. Adjust if necessary.
2.
Remove the small plate on top of the governor section of the air/gas ratio controller.
Referring to the diagram on page 16, set the air/gas ratio on scale (1) to 0.8 by adjusting
screw (1), anti-clockwise to increase, clockwise to decrease.
Set the ratio on the remaining scale to half a division on the positive side of ‘0’ by
adjusting screw (2) in the same way, anti-clockwise to increase, clockwise to decrease.
3.
Remove the cap from the start gas governor and set the adjusting screw approximately
half-way between the maximum and minimum settings, turning the screw clockwise to
increase the setting and anti-clockwise to decrease it. Replace the cap.
Never adjust the governor to its maximum setting.
4. Check, and if necessary, re-set the ignition electrode gaps to 2.5 – 3mm. Access to the
burner head is explained on page 44.
5. Ensure that oil of the correct class is available at the required temperature (on MDFR
systems refer to the table on page 9) and pressure.
IT IS RECOMMENDED THAT THE BURNER SHOULD BE COMMISSIONED FOR OIL FIRING IN
THE FIRST INSTANCE. SHOULD OIL NOT BE AVAILABLE TO THE BURNER THEN GAS
COMMISSIONING CAN PROCEED ONLY IF THE PUMP DRIVE COUPLING IS REMOVED FROM
THOSE BURNERS WHERE THE OIL PUMP IS DRIVEN BY THE BURNER FAN MOTOR.
IT MUST BE NOTED IN ALL CASES THAT WHEN OIL IS AVAILABLE TO THE BURNER THE
UNIT MUST BE RE-COMMISSIONED ON BOTH FUELS. NOTICE SHOULD BE MADE OF THIS
FACT, BOTH AT THE BURNER AND WITHIN THE BURNER HANDBOOK AND APPLIANCE LOG
BOOK.
