verify the integrity of the combustion chamber gasket and ensure the pilot line and thermopile leads are correctly routed through the assembly to prevent premature wear or signal interference

reducing resistance and heat buildup at the connection points

Can this be used in both heating and cooling applications

you must install a 500 Ohm resistor (typically the ZG-R01) across the input wires to convert the current signal to the required 2-10 VDC range

Key Benefits: OEM Precision Fit: Specifically engineered for Lochinvar and A

Dwyer Instruments L4 Float Switch 318518-761 verify the integrity of theThe Dwyer Instruments L4 Flotect level switch is a rugged, explosion proof float switch designed for demanding industrial liquid level monitoring. Engineered with a durable brass body and a 316 stainless steel float, this side wall mounting unit is built to manage pump control, tank alarms, and valve automation without the failure points common in lesser hardware. By utilizing a unique magnetically actuated switching design, the L4 eliminates the need
