VII. System Start-up

WARNING

All boilers equipped with burner swing door have a potential hazard which can cause severe property damage, personal injury or loss of life if ignored. Before opening swing door, turn off service switch to boiler to prevent accidental firing of burner outside the combustion chamber. Be sure to tighten swing door fastener completely when service is completed.

A.ALWAYS INSPECT INSTALLATION BEFORE STARTING BURNER.

B. FILL HEATING SYSTEM WITH WATER. Refer to Section III, G.

C.CHECK CONTROLS, WIRING AND BURNER to be sure that all connections are tight and burner is rigid, that all electrical connections have been completed and fuses installed, and that oil tank is filled and oil lines have been tested.

D. LUBRICATION — Follow instruction on burner and circulator label to lubricate, if oil lubricated. Most motors currently used on residential type burners employ permanently lubricated bearings and thus do not require any field lubrication. Water lubricated circulators do not need field lubrication.

Do not over-lubricate. This can cause as much trouble as no lubrication at all.

E. Adjust control settings with burner service switch turned “ON” and room thermostat set 10° below room temperature.

1.Adjustment and display modes of the L7248/ L7224 Oil Electronic Aquastat Controller.

a.On the L7248/L7224, the overall range of the High Limit is from 180°F to 240°F (82°C to 116°C).

b.Set the High Limit (designated HL) on the

L7248/L7224 Aquastat Control at 180°F. This temperature setting may be varied to suit requirements of installation. Differential is fixed at 15°F.

i.Adjusting Settings:

To discourage unauthorized changing of

Aquastat settings, a procedure to enter the adjustment mode is required. To enter the adjustment mode, press the UP, DOWN, and I buttons (see Figure 18) simultaneously for three (3) seconds. Press the ‘I’ button until the feature requiring adjustment is displayed (press the “I” button again and will display LL (Low Limit on L7224):

Then press the UP and/or DOWN buttons to move the set point to the desired value. After 60 seconds without any button inputs, the control will automatically return to the READ mode.

ii.Display:

In the RUN mode, the Aquastat will flash “bt” (boiler temp.) followed by the temperature (i.e., 220), followed by °F or °C.

To read boiler settings, press the ‘I’ key to read the parameter of interest. For example, press I (HL) High Limit is displayed, followed by a three-digit number, i.e., 220, followed by °F or °C.
