LOW WATER CUT OFF (OPTIONAL)

The low water cut off automatically shuts down the burner whenever water level drops below the level of the sensing probe. A 3 second time delay prevents premature lockout due to temporary conditions such as power fluctuations or air pockets.

LOW WATER CUT OFF

HIGH AND LOW GAS PRESSURE SWITCHES - MANUAL RESET

The low gas pressure switch mounts upstream of the gas pressure regulator

to ensure that sufficient gas pressure is present for proper regulator performance. The low gas pressure switch automatically shuts down the boiler if gas supply drops below the factory setting of 6" W.C. for Natural gas, and 10" W.C. for propane gas.

The high gas pressure switch (optional) mounts down-stream of the gas pressure regulator. If the gas pressure regulator fails, the high gas pressure switch automatically shuts down the burner.

GAS PRESSURE SWITCH

Pressure Control Device

A uniquely designed pressure control device is used for ADB to ensure the proper operation of the unit even if there is a slight change of blower pressure.

CAUTION:

The rubber hose has to be securely connected between the blower and regulator during the time the unit is running.

CAUTION:

Do not block the hose fitting/orifice on the blower. Regular inspection is required.
