Final Adjustments; Setting Combustion Efficiency - Wayne EH User Manual

2. With the burner running, use a 3/8 inch wrench to open the bleeder valve about one-half turn (Figure 24). Allow oil
to drain into the container until a steady, clear bubble free oil stream is noticed. Close the bleeder plug.
Note: If safety lockout occurs during burner operation, reset after one or two minutes.
3. Close the ignition device mounting plate, and tighten the hold down clip screw

FINAL ADJUSTMENTS

At this point a final adjustment should be made by the use of a COMBUSTION TEST KIT. After operating for ten minutes
to warm up the appliance, a smoke tester should be used to take a smoke reading. Smoke test should read no greater
than #1 (Shell Bacharach scale), and less than a #1 smoke is desired. At times, a new heating unit requires more time
than this to burn clean due to the oil film on the new heater unit surfaces. Recheck draft and take a CO
fire and in the stack. If a large differential between CO
readings must be taken ahead of draft control, if used. The CO
rates 1.00 gal/hr or below, and at least above 10% for oil rates over 1.00 gal/hr Units should be started and stopped
several times to assure good operation. Open ignition device mounting plate, unplug solenoid valve lead, and check the
oil primary control (if equipped) for normal operation see
AND R8184G CONTROLS

SETTING COMBUSTION EFFICIENCY
