## Customer Reviews

### ⭐⭐⭐⭐⭐ Fixed It!
*by J***. on January 22, 2025*

I replaced the original valve with this new one and my fireplace now works again!

### ⭐⭐⭐⭐⭐ Fireplace Park
*by B***J on February 17, 2024*

This part was a little trying, but we eventually got everything working. Adjustments had to be made.

### ⭐⭐⭐⭐⭐ Worked in my 23 year old propane gas fireplace
*by J***4 on May 10, 2021*

Recently bought a house with a propane fireplace that wouldn't stay lit. Replaced thermopile and that still didn't work. Took a chance and ordered this gas valve. It works perfectly. Photos depict the gas log model, etc. and the gas valve I replaced. I did the replacement myself but I am pretty handy and comfortable working with natural gas appliances. I know how to check for leaks, etc. Happy with the purchase. Much less expensive than a replacement gas log unit.
