Foul Smelling Fireplace

[Sal-Ip]

Hello all
In 2016 I installed the Mendota Full view Linear ML47" gas fireplace. After install had some smell issues and after it was replaced we found that the smell was being caused by the fake logs. We removed the logs and replaced it with Fire stones and chips. The Unit worked great after that. We never used in the summer and we turned it on for the first time last week and after 1 hour of it running we get a foul smell again. I even ran the unit for 8 hrs with the windows open and days later still smells when we turn it on.. Any Ideas as to why this is happening again??

Can you describe the foul smell?

I have an issue with my insert that was installed in 2015. I get a foul smell on startup until the liner heats up and starts drafting properly. Once it heats up the smell goes away.

Maybe it’s that dead squirrel stuck between the liner and the old clay flue. They smell worse when heated.

Hard to explain the smell, but the vent is capped so nothing can get into the flue pipe. The unit has run passed the liner heating up and I had it running a total of about 10 to 13 hrs.
