44Start and run for 20 minutes.
4Remove sampling point plug ( J ) to check
the smoke reading is between 0-1. If the
smoke level is above 1, check the combustion
settings are correct and the oil nozzle is in
good condition.
NOTE: Smoke readings may be inaccurate until
the smoke from burning organic binder in
the access door insulation has ceased.
