Okay, if you're dealing with a vent-free gas fireplace that needs a new pilot assembly, this LPG8404 replacement is exactly what you're looking for.
This thing is designed specifically for LPG propane gas appliances and replaces a bunch of models including CIVF-25, VFH-33M, VFYR-16, VFCR-25, VFHD-32R, and several others.
It's compatible with Empire, Vanguard, and most manufacturers that make gas stoves and heaters.
The assembly comes complete with a 750mv thermopile, integrated thermocouple, stainless steel pilot burner, and ceramic igniter electrode - basically everything you need in one package.
It's built with high-quality materials and uses that Oxygen Detection Safety (ODS) technology that's crucial for safe gas fireplace operation.

The connections are standard 3/8-24 UNF threaded gas connection with M8x1 threaded nut, so your gas technician should have no trouble installing it.
Speaking of installation - it's pretty straightforward for a pro, maybe 15-20 minutes tops.

Just make sure after installation you check for any gas leaks at the connections (safety first, people!).

If your Empire or compatible vent-free fireplace isn't lighting properly or the pilot keeps going out, this ODS assembly replacement will likely solve your problems.

It's one of those parts that seems complicated but is actually a pretty standard replacement job for anyone familiar with gas appliances.
