Installed into my 25 year old Heatilator fireplace in 30 mins and fixed my problem with the burner going out randomly.

### ⭐⭐⭐⭐⭐ Replace the entire assembly
*by M***R on November 16, 2025*

A great replacement part for my gas fireplace. I wished that I had purchased the pilot assembly from the start. Instead, I bought one of the components (thermocouple) but it didn't fix the problem. I'm happy now that it's installed and working fine. Easy to install and of good quality.
