Resideo Q313U3000 Universal Thermopile
The Resideo Q313U3000 Universal Thermopile is a heavy-duty, multi-couple generator designed for reliable pilot flame sensing in gas-fired heating systems. This 750 mV thermopile utilizes multiple thermocouples connected in series to increase millivoltage output, providing enough DC power to operate an automatic millivolt gas control system without an external power source. At 35 inches in length, this lead is versatile for various appliance depths and configurations. The Q313U3000 features spade terminals and arrives with a comprehensive universal adapter kit—including a 1/2" attaching nut, split nut, spade-to-quick-connect adapter, and PG9 adapter—ensuring compatibility with standard pilot burners like the Q314, Q327, and Q382 series. Built for high-heat environments, the hot junction is rated for 1400°F (760°C), ensuring stable pilot generator performance in residential and commercial furnaces, boilers, and water heaters. This Honeywell thermopile replacement is the industry standard for technicians seeking a robust, drop-in solution for standalone gas valves.
Key Benefits- Universal Compatibility: Includes multiple mounting adapters (split nut, push-in clip, and PG9) to fit various pilot burner brackets.
- Self-Powered Operation: Generates 750 mV current, allowing the gas valve to function independently of building electrical power.
- Extended Reach: The 35" lead length provides flexibility for larger combustion chambers and specialized equipment.
- Terminal Versatility: Equipped with spade terminals and a quick-connect adapter to match any gas valve connection point.
- High Temperature Durability: Engineered with a 2.89-ohm resistance and a hot junction rating of 1400°F (760°C) for long-term survival in the pilot flame path.
How do I test if the Q313U3000 is still functional?
Using a multimeter set to the millivolt (mV) range, measure the output across the two terminals while the pilot is lit. An open-circuit reading should fall between 600 mV and 750 mV for a healthy unit.
What is the difference between a thermocouple and this thermopile?
A standard thermocouple typically outputs 30 mV and only powers the safety coil. This 750 mV thermopile (or generator) contains multiple thermocouples to produce higher voltage, which actually powers the entire millivolt gas valve operator.
Can I use this to replace a shorter 19-inch or 24-inch thermopile?
Yes, the Q313U3000 is an ideal universal replacement. Excess lead length should be carefully coiled away from the flame and sharp edges, but the electrical performance remains consistent.
