Taking measurements
Allow burner to operate for 15 to 20 minutes before a
combustion test. Earlier combustion tests can lead to
incorrect readings as a result of burning off the sealant
rope. We recommend checking the burner after a few
weeks of operation.
Required instruments:
– CO

measuring equipment
– Draft measuring equipment
– Oil pressure gauge
– Stack thermometer
– Smoke tester
V
Check the combustion chamber pressure at the pres-
sure testing port [1].

Check the breeching draft at a test port in the vent con-
nector.
