Description
The Baso Gas Products K15DA-48 is a precision-engineered thermocouple designed for reliable performance in standing pilot ignition systems. Generating a 20–28 mV open circuit output, this thermocouple provides the consistent millivoltage signal required to hold gas valve operators open during normal pilot flame operation — a critical safety function in millivolt heating appliances.
With a generous 48-inch lead length, the K15DA-48 offers installation flexibility to reach gas valves in a wide range of furnaces, boilers, water heaters, and other standing pilot-equipped appliances without the need for extension leads or awkward routing.
Key Features
- Open circuit mV range: 20–28 mV
- Lead length: 48 inches for flexible routing and installation
- Designed for use in standing pilot ignition systems
- Generates millivoltage signal to energize and hold gas valve operators
- Compatible with a wide range of millivolt gas valves and heating appliances
- Reliable BASO quality for long service life
Application
The K15DA-48 thermocouple is ideal for replacement or new installation in residential and light commercial heating equipment that uses a standing (continuous) pilot ignition system. It is commonly used in furnaces, boilers, water heaters, and gas fireplaces where a millivolt gas valve requires a thermocouple signal to maintain the pilot safety circuit.
Installation Notes
- Ensure the thermocouple tip is positioned correctly in the pilot flame for optimal mV output
- Tighten the connection nut finger-tight plus a quarter turn — do not overtighten
- Verify compatibility with your specific gas valve model before installation
- Replace thermocouple if measured mV output falls below the minimum valve hold-in requirement
