US Merchant Heatilator Heatnglo Direct Vent Fireplace 27" Thermocouple replaces Robertshaw 446-511

I bought it so I didn’t have to pay a higher price from fireplace maintenance company. Works as described

This thermocouple was a perfect fit for my Harman LP gas fireplace. The threads matched correctly at the thermocouple and gas valve ends. I gave 3 stars for installation because it's a finnicky job that takes a some patience, there isn't a fitment problem. Besides installing the thermocouple you have do disassemble quite a bit of the fireplace to make the replacement and there's tight quarters at the gas valve end. The fireplace is 18 years old, the first thermocouple lasted 14 years, the second one lasted 4. I hope this one is equal to the original!

Durable product that is easy to install.

Worked as promised. Good value!

Had problems keeping the pilot light lit for longer than a couple hours. One google search later they showed me how to test my current thermocouple as well as informing me they go bad quite often so its not unusual at all. Sure enough this fixed it and now its running perfectly. I was so happy with the fit and results that i even bought another one to keep on hand for just in case i should ever need another one.

this replacement part fits perfectly.

Broke

Ordered and arrived very quickly. A prefect replacement for our Heat-N- Glo fire place. We hope this one lasts as long as our 12 year old original.

Yes it worked. Just a tad overpriced.m

Repaired my fireplace. Fit and works perfectly.
