Millivolt Generator

Installed this today. Let it warm up good and threw a voltmeter across it at the terminals, which were connected to the gas control. Moving the thermopile in it's holder in the ventless gas fireplace -- for more or less pilot flame exposure, the best milivolt output measurement I got was 525mv with the thermopile at it's max exposure with my current setup and clearances. I could not scoot the pile up any further for more flame exposure as it's base hub stopped the travel. From my experience with several brands of thermopiles over the years including the really expensive ones, this is a decent reading of 525mv.From here I want to see how long it remains functional compared to those costing almost twice as much. So far so good. Easily operates my gas valve on the fireplace.Today is 7-14-2012. I used this thermopile through the winter, and have so far found this to be one of the stronger generators I have used over 15 years. I will buy this again when necessary. I see no need to spend more on the other brands, and some of the expensive name brands I have used have failed far too soon.

Thermopile replaced my failed unit. Easy to install and functions as it should. Good quality and value, and arrived quick.

Great

Used in an old floor furnace

I bought this item November 10, 2018. It seemed to fix my problem, but it has already quit working. Does it have a warranty? I am very disappointed that it's already quit working.

Good price decent del time product worked great

Purchased Nov. 2020 and still working great as a replacement for my outdated old wall heater.

After installing the millivolt generator, the pilot light worked fine for a couple of weeks and then the it failed to stay lit--the same problem we were trying to cure. I have not taken time to test the generator to see if it has failed or if the problem is related to the control valve.
