Description
Pentair 071515 Pilot Generator (Q313A) with Clip | Millivolt Heater Pilot Thermopile
The Pentair 071515 is an OEM replacement pilot generator / thermopile (commonly listed as Q313A with clip) for select Pentair pool and spa heaters. This millivolt pilot generator produces the electrical signal used by compatible millivolt gas valve systems, helping the heater pilot circuit operate correctly.
Common Compatibility (Verify Before Ordering)
- Pentair MiniMax pool/spa heaters (commonly listed for models 75 and 100)
- Pentair MiniMax CH heaters (commonly listed for 150, 200, 250, 300, 350, 400)
- Pentair MiniMax Plus heaters (select models)
- Pentair PowerMax / TI heater applications (listing dependent; verify by heater model and parts diagram)
Heater parts can vary by model, fuel type, and production version. Always confirm your exact heater model and parts diagram before ordering.
Key Details
- Part number: 071515
- Part type: Pilot generator / thermopile
- Common description: Q313A pilot generator with clip (millivolt)
- Function: Generates millivolt power from the pilot flame for the heater control circuit
- Includes: Clip (commonly listed)
What This Part Does
- Converts pilot flame heat into a small electrical (millivolt) output
- Helps the heater gas control system verify pilot operation
- Supports reliable pilot hold/open operation on compatible millivolt heater systems
- Restores heater startup performance when the original pilot generator is weak or failed
Common Signs You May Need Replacement
- Pilot lights but will not stay lit (after confirming gas supply and pilot flame quality)
- Weak/intermittent millivolt output causing unreliable heater startup
- Corroded, damaged, or brittle pilot generator lead/wiring
- Heater service diagnosis confirms failed or weak thermopile/pilot generator
Installation Notes
- Turn off gas and electrical power to the heater before servicing.
- Confirm the replacement matches your heater model and pilot assembly style.
- Install the generator in the same position/orientation as the original so it sits correctly in the pilot flame.
- Inspect the pilot assembly, pilot tubing, and connections while open; clean debris and corrosion as needed.
- After installation, test pilot operation and confirm proper heater ignition sequence.

Maintenance Tips
- Keep the pilot assembly area clean—dust, rust flakes, and debris can affect pilot flame quality.
- If the heater is hard to light, inspect the pilot orifice and flame pattern before replacing parts.
- Check wire terminals for corrosion or loose connections during heater service.
- Have gas/heater diagnostics performed by a qualified technician if ignition problems continue after parts replacement.
