Description
The ASCO PG9A37JTL22S2 is a 750mV Pilot Generator designed to provide dependable thermoelectric power generation in millivolt gas heating systems. By harnessing heat from a standing pilot flame, this pilot generator produces the millivolt output needed to operate compatible gas valves and controls — entirely without an external electrical power source.
Key Features
- 750mV thermoelectric output generated directly from standing pilot flame
- Enables self-powered gas valve operation — no external electricity required
- Designed for use in millivolt heating systems including furnaces, boilers, fireplaces, and water heaters
- ASCO quality construction for long-lasting, reliable performance
- Direct replacement pilot generator for compatible millivolt systems
Application
Millivolt pilot generators are a critical component in standing pilot gas heating systems. When the pilot flame heats the generator’s thermoelectric element, a small but precise voltage is produced — typically 750mV — which powers the main gas valve and keeps the system operating safely. The ASCO PG9A37JTL22S2 is engineered to deliver consistent output, making it a trusted choice for HVAC technicians performing service, repair, or replacement work on millivolt heating equipment.
Compatible Applications
- Residential and commercial gas furnaces
- Gas-fired boilers
- Gas fireplaces and log sets
- Gas water heaters with standing pilot ignition
- Millivolt radiant heaters
