7.HIGH LIMIT CONTROLLER

The High Limit opens and turns off the burner when the water temperature reaches the setpoint. The High Limit automatically resets after the water temperature drops past the setpoint and through the Differential. The L7248 models have High Limit Differential presets of 15°F (8°C). The L7224 models have High Limit Differential presets of 10°F (6°C).

8.LOW LIMIT AND CIRCULATOR CONTROLLER

On a temperature rise, with the adjustable Differential at the default setting of 10°F (6°C), the burner circuit breaks and the circulator circuit makes (assuming no call for heat is present) at the Low Limit setpoint. On a temperature drop of 10°F (6°C) below the Low Limit setpoint, the burner circuit makes and the circulator circuit breaks. See Figure 24.

F.REMOVE GUN ASSEMBLY

1.CL Series boilers are equipped with Beckett AFG burners. Items to be checked are nozzle size, head size, gun setting, and positioning of electrodes. This information is shown in Figure 25 and Table 9 at rear of manual.

2.CL Series boilers are equipped with Carlin EZ-HP burners. Items to be checked are nozzle size, head bar size, gun setting, and positioning of electrodes. This information is shown in Figure 25A and Table 9 at rear of manual.

3.Reinstall gun assembly.
