The LWCO is located on the top left side of the rear
enclosure. To test for proper function the boiler must
be empty of water.
With the boiler empty, power on the CleanFire. The
Control should not allow operation, and the Indication
LED on the LWCO should be red.
Fill the boiler with water. Once the LED changes from
red to green, the control will allow for operation.
To test during normal operation, press the test button
on the side of the LWCO The light should turn red and
the boiler operation should stop. Release the button to
restart normal operation.
The LWCO should be tested once a year, or any time
the boiler is fired after an extended down period.
Low Water Cutoff - Cleaning
The LWCO should be cleaned every 5 years or if indi-
cated by a red service light. To clean, remove the LWCO
from the boiler line and remove all oils, fluxes and scale
