CAUTION￿

An appliance allowed to operate at return temperatures below the specified minimum settings may experience problems with the operating controls, safety switches, obstruction of the flue gas passages on the primary heat exchanger, incomplete combustion and possible flue gas spillage. Sustained operation at lower than specified water temperatures may cause hazardous conditions that may result in personal injury or non-warrantable damage to the appliance.

A boiler installed above radiation level must be provided with a low water cutoff device either as part of the unit or at the time of installation.

WATER FLOW SWITCH

A water flow switch is factory installed in the internal bypass piping on all heating boilers, hot water supply boilers and water heaters. The flow switch is wired in series with the 24 VAC safety control circuit. This wiring connection installs the flow switch in the 24 VAC safety circuit to prove water flow before main burner ignition. A factory supplied flow switch installed in the discharge piping from the top header requires a minimum flow of 26 GPM to make the flow switch and start burner operation. A water flow switch meets most code requirements for a low-water cut off device on boilers requiring forced circulation for operation. A status point alarm of LowH2OFlow will be indicated in the Command Display on a low water condition as sensed by the flow switch.

LOW WATER CUTOFF

(If Equipped)

If this boiler is installed above radiation level, a low water cut-off device must be installed at the time of boiler installation. Electronic or float type low water cut-offs are available as a factory supplied option on all models. Low water cut-offs should be inspected every six months, including flushing of float types. A status point alarm of LowH2OFlow will be indicated in the Command Display on a low water condition as sensed by a low water cutoff.
