Heatilator & Heat-N-Glo Natural Gas Pilot Assembly 4021-736

Note the models that this fits in the description. For my model (8000TR-OAK), it says only for serial numbers pre 00211XXXX. I have a post serial number and this did not work on mine. While it all fits fine, the pilot orifice is different and the flame was too small to get proper voltage from the thermopile. So don’t ignore the serial number blocks on the models. I purchased a different on for the post serial number block and it works perfectly. I am still rating this five starts because it works fine, just not for my model.

This part matched to original part and fit perfectly on my Heat N Glow fireplace. After installation, the unit works great! Highly recommend!

I replaced the pilot assembly on my 1999 Heat-N-Glo 8000trc gas fireplace. This item is a plug and play. I was able to replace the pilot assembly without disconnecting any gas lines, although I did shut the gas off. For the customer who said in her review that the gas line was crimped on her item, the line that she was referring to was not a gas line. The thermopile does connect with a copper tube, and is crimped on purpose so that you don't try to connect that part to gas. The thermopile copper tube was crimped on my assembly too. The pilot line (silver aluminum line) is the only gas line in this assembly. I did seal the bracket holes that the lines run through with the supplied gaskets and some Permatex 81630 Ultra Red High Temperature Gasket Maker (bought on Amazon). After a few bloody knuckles, I soap tested the pilot connection and all gas connections. Works like a charm. Pilot has been running for a week and the fireplace starts up with the flip of a switch each time. I did not need to adjust the pilot flame, but it is only the turn of a screw if need be.

Replaces original perfectly. It was the reason my fireplace was not working. Looks as good or better than the original pilot assembly

Not compatible with my fireplace (Heat and Glo SL-550TRS-C). The thermopile sits too low in the metal housing and isn't exposed to enough flame to generate the necessary voltage to keep the gas valve open. Ended up purchasing a thermopile and installing it in my original bracket. Avoid this product.

Much needed fireplace part. Quick Assembly!

Installed on a Heat-N-Glo 6000TRB nat gas insert fireplace that had a failing thermopile. Takes a little bit of time to access the old pilot assembly but once this new one was installed the fireplace works like a charm. Saved 3x the cost for a local service company to do the same work.

Kinda of a pain to install, but not difficult. Just some reaching around in the fireplace and you are good to go!
