I was trying to determine if my ventless gas fireplace logs were causing the bad odor or the fireplace itself, so I decided to remove the logs, run the fire for 45 minutes, and see if the smell still occurred. It did, so now I know I need to buy newer/better logs. But as I was researching logs, I stumbled upon someone saying that moving ventless logs from the fireplace is very bad. Can anyone confirm this and if so, explain why please? Thanks!
