So in an effort to update my fireplace I was looking to remove the old burner meant for a gas log set and install an H-burner for a fire glass setup. The original nipple was too long traveling into the box and would have been unsafe so hacked off a couple of inches.
My original plan was to rethread the pipe but the more I started thinking about it I figured just removing the pipe entirely would make more sense. Well the issue is the pipe won't budge with a 12" pipe wrench and I'm hesitant to start really wailing on it not knowing the actual setup within the wall. The pipe is about 17" to the next fitting, which I assume to be an elbow. The shut-off valve is of course on the other side of the fireplace so I'm assuming it elbows around the back of the fireplace and wraps back around to where it exits into box.
Am I fool trying to complete this blindly and should just bite the bullet and try to get access from the outdoor wall? Or the interior drywall? I've attached pictures for opinions.
