Here’s something we see all too often during our energy audits around the greater Atlanta area.. A contractor has installed a flexible pipe on the natural gas line.

This natural gas line is a thin walled flexible pipe, which is fine unles it goes through a metal hole to get into the furnace.

This is an “explosively” dangerous problem

In and of itself that is not an issue. Flexible gas lines are acceptable as long as it’s installed properly. What isn’t allowable is that the flexible piping penetrates through the metal wall of the furnace. It’s fine to have flexible pipe outside or inside of the furnace but not going through.

Inside each furnace is a blower motor that spins at a very high rate of speed. This creates vibrations that shake the body of the furnace. If that flexible pipe comes into contact with that rough metal edge, even small vibrations over time can wear a hole in the pipe.

But hey, whats a few small gas leaks among friends right?  It literally could be the difference between a nice warm  house or a blazing inferno of death the next time your furnace lights up. Even scarier is the fact that most old furnaces still have a constant pilot light that flickers away mere inches from the gas line.

We tested for gas line leaks on the system and didn’t find any… yet.

Check your furnace out for this. If the installer didn’t get this right, they may have skipped over a few of those other pesky Building Codes as well.

Not all contractors are as slack-tastic as this one was. We have a network full of outstanding professionals that fix problems like this every day.  I’m sure some of them are cringing at the picture above as much as I am.
