## Questions & Answers

**Q: Will this work in a kingsman fdv350 oem part# 1000-p136wr?**
A: If it is long enough. My cheat sheet recommends a 30", but a 24" will usually fit units of this type. Measure your old one. The only differences are the mounting hardware and the length!

**Q: normal volt readings  for this thermopile?**
A: I don't remember measuring it, but it worked.  Usually the biggest factor affecting the thermopile out put is the intensity of the pilot impingement.  The same thermopile can produce anywhere from 300 to 750 millivolts depending on the intensity of pilot impingement.

**Q: does this fit a williams wall heater?**
A: Sorry, but I do not have the list of products that will accept this thermopile.  I used it for a gas log fireplace unit.

**Q: how many volts does this thermopile generate?**
A: all thermopiles generate .750 volts not connected to anything, and .500 when under load.  (750 and 500 'millivolts' respectively)
