OPERATIONAL TEST PROCEDURE
IMPORTANT: Do not run boiler unattended until the following procedure is completed
1.
Before raising the water level above the Model 1100, turn on power to the boiler and set the thermostat to call for heat. Both the green
“POWER” LED and amber “LOW WATER” LED should illuminate. The burner should not fire. IMPORTANT: If the burner fires with no water
at the probe, immediately shut down power to the boiler and refer to the Trouble Shooting instructions below.
2.
Proceed to fill the boiler with water. When water reaches the LWCO position, the burner should fire. If the burner does not fire, refer to the
Trouble Shooting instructions below.
3.
Turn off the power to the boiler and finish filling the system.
4.
Before leaving the job, power up the system and push the TEST button on the Model 1100 to simulate a low water condition. The amber
“LOW WATER” LED should illuminate and the burner should shut down.
SERVICE & MAINTENANCE
EVERY YEAR
Check control operation annually by pressing the TEST button. The amber “LOW WATER” LED should illuminate and the
burner should shut down.
5 YEARS
Remove the low water cut-off every five years and clean all surfaces in contact with water.
IF AMBER LED
If the amber “LOW WATER” LED is blinking, the control should be removed and all surfaces in contact with water should be
IS BLINKING
cleaned. The blinking LED indicates that the sensor may be getting coated with oil or other residues in the system. If left
unchecked, this could result in a nuisance low water shutdown.
TROUBLE SHOOTING
IF THE BURNER DOES NOT SHUT DOWN
(when water is below the probe or
when the TEST button is pressed)
1.
Turn off boiler power immediately and re-check wiring.
2.
Turn off boiler power and drain system. Remove low water cut-
off and check for adequate clearance – no metal should be in
contact with the control’s metal probe tip.
IF THE BURNER DOES NOT FIRE
1.
Make sure water has reached the level of the control.
2.
Check green wire for proper ground. Make sure the wire is
attached to an unpainted surface that is electrically common to
the boiler.
3.
Check to ensure the control’s metal probe tip is not surrounded
by an air pocket. Shut down power to the boiler and slowly
loosen, but do not remove, the control. Allow any air to escape.
When water begins to seep past threads, retighten the control.
4.
Re-check wiring and check for correct incoming voltage.
