Why Contractors Specify BASO Gas Products
BASO provides a broad cross-reference range of thermocouples, thermopiles, and pilot assemblies covering virtually all residential and commercial gas appliance manufacturers. BASO millivolt gas valves and thermopiles serve standing pilot systems that operate without external electrical power.
How to Choose a BASO Product
Match thermocouple or thermopile millivolt output to the gas valve specification. For thermocouples, match thread size and sheath length to the existing pilot assembly. For thermopiles, verify the millivoltage required to power the gas valve and controls.
Frequently Asked Questions
- Thermocouple vs. thermopile? Thermocouples hold safety seat open only; thermopiles power entire millivolt circuits.
- How to diagnose thermocouple failure? Pilot will not stay lit after releasing the pilot button.
- Universal fit? BASO offers universal types; verify thread size and length against the appliance assembly.
- What is a millivolt system? Powered entirely by thermopile output, operable without external electrical service.
- Ignitor cross-compatibility? BASO ignitors are cross-referenced to OEM applications; verify resistance and configuration before ordering.
