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 the Smoke No., if clean wait 10 minutes and measure CO
2
.
A
djust the air shutter (see fig 8.2a), if necessary, open to reduce CO
2
, close to increase CO
2
. If the air shutter
is adjusted, re-check the Smoke No.
