More About Baso Gas Products

BASO Gas Products LLC is a gas controls manufacturer founded in 1914 in Watertown, Wisconsin, producing thermocouples, thermopiles, pilot assemblies, gas valves, ignitors, and furnace boards for residential and commercial gas appliances. BASO products are RoHS compliant, ISO 9001-2015 certified, and meet ANSI, CSA, and UL requirements. BASO distributes through wholesale HVAC channels including SupplyHouse.

BASO Gas Products Product Lines

  • Thermocouples: Millivolt safety devices for standing pilot gas valves.
  • Thermopiles: Higher-millivoltage generators powering full millivolt gas valve circuits without external power.
  • Pilot Burner Assemblies: Complete pilot replacement assemblies for gas appliances.
  • Gas Valves: Millivolt and electric gas valves for heating applications.
  • Ignitors and Spark Electrodes: Hot surface and spark ignitors for electronic ignition systems.
  • Ignition Controls and Furnace Boards: Electronic ignition sequencing and flame supervision controls.

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.
