COMBUSTION TESTS
Fit combined air bleed manifold and 0-300psi (0-20 bar) pressure gauge to the appropriate oil pump
connection, and replace burner.
Switch on the electric supply to the boiler.
When the burner motor starts, on one pipe systems, it may be necessary to temporarily open the air bleed
screw on the test manifold.
Once the burner is firing check and if necessary adjust the oil pressure.
Carry out combustion checks by inserting probes into sampling points provided or at the flue outlet.
Check Smoke No., if clean wait 10 minutes and measure CO2.
Adjust the air shutter (see Fig 8.2a), if necessary, open to reduce CO2, close to increase CO2.
If the air shutter is adjusted, re-check the Smoke No.
Check the flue gas temperature.
The figures should agree with data in Boiler Commissioning Data, Section 3.

8:2 AIR SHUTTER ADJUSTMENT
The burner has a fixed Air Shutter with manual adjustment.
To adjust the CO2 at the Air Shutter use a 3mm Allen key as shown. To increase the setting turn the air
shutter clockwise (+) and to decrease turn anti-clockwise (-).
