This is a good fit. I had to drill the hole bigger on the bottom to get the Pilot light bolt down through. This was not a problem. Everything fit perfectly. If there is an issue getting the threads to screw in just a drop of oil on the threads will help. This is just what I was looking for. My gas stove works great now. I had a pilot issue that was unsolvable after trying everything. (replacing thermocouple, thermopile, etc.) This fixed it. I have two of these stoves which work great in the winter. I ordered two kits more to have on hand. Both of my stoves are almost 20 years old and this makes them like new. Thank you :)

Exact replacement for my Lennox/Superior fireplace. In about an hour I replaced the old, rusted through pilot assembly with a new one despite having never worked on one of these before. Works great! Thanks! Oh, and it arrived a few days before the earliest estimated date.

It was super easy to install on my lennox dt 4035 fireplace. Just be careful when uncoiling the gas lines because they can crimp easily if you aren't careful. It might take a few seconds to purge the air in the pilot light gas line because toy just replaced it. It gave my 17 yr old gas fireplace new life and it starts super easy with the new ignitor. Take your time and take pictures before unassembling anything to use as references. Also keep track of any screws and where they go. One last note the threads on the nuts that go into the gas lines can EASILY get crossed treaded so if it doesn't feel like it is screwing in back it out and try again. If you cross thread it it might not go flush and cause a gas leak so be careful. Can't be happier with my working fireplace.

Perfect fit; works beautifully to restore my fireplace flame. Easier and cheaper to just replace the whole assembly instead of piecing it out as each of the 3 separate devices go out. Decent price (not great), but much cheaper than buying each piece. Relatively easy to install by a DIY-er. Total cost less than 1/4 of calling a service company. Would undoubtedly DIY again AND buy from this vendor.

Not so much about the part but the supplier, Allparts Equipment, is a good company. I was having some issues with installation and they actually called me a couple days later to make sure everything worked out.
