Integrated piezo igniter simplifies the pilot lighting process and reduces the need for external ignition tools

While the valve body can be mounted in multiple positions

the outlet side is typically threaded to accept standard 3/4" hose connections for controlled drainage during system maintenance

Corrosion Resistance: Engineered with robust materials to withstand the acidic environment created by combustion condensation

Resideo AT140A1042 Transformer 326058-757 Integrated piezo igniter simplifies theThe Resideo AT140A1042 Transformer is a heavy duty 40VA power supply engineered for reliable performance in HVAC control circuits and zoning systems. This foot mounted transformer features a dual voltage primary (120V 240V) at 60Hz, providing a steady 24VAC output for powering thermostats, relays, and gas valves. The multi tap connection design simplifies installation across various line voltage configurations, ensuring the secondary output remains
