Integrated Piezo Igniter: Simplifies the pilot lighting process without requiring external ignition sources

If the glass integrity is compromised by debris or pressure spikes

it must be installed in the correct flow direction (typically the cold inlet) to allow water to enter the tank while preventing thermal siphoning from the heat source

this unit integrates seamlessly with complex multi-stage HVAC systems

Siemens Combustion SQM40.215R11 Actuator 322057-301 Integrated Piezo Igniter: Simplifies theThe Siemens SQM40. 215R11 Actuator is a heavy duty electromotoric component designed for the precise positioning of air and gas dampers or butterfly valves in industrial burner systems. Operating on a 110V 120V AC power supply, this model features a 0 135 Ohm resistive input signal, providing reliable modulating control for high turndown burner applications. Built with a robust NEMA 4 (IP66 equivalent) aluminum housing, it is engineered to withstand
