Were are the AFTER pictures ?

There was a refrigerator 16" in front of this furnace otherwise I would have gotten a better picture. I find it funny that a few days after this post I run into one like it. Except rather than use a nipple, they used a coupler. As you can see, they did put the coupler where it penetrated the cabinet. Reason for me being here? Bad gas valve. Replaced the valve, used a whole two street 90s and one 12" nipple and this issue has been corrected. Yes, I did add a sediment tee outside the cabinet.

Attachment 346901

The flex connector must be rated for the application. Some are for indoor use only.

That's a legitimate question. Could someone please explain ?

A typical proper application with a flex connector would be piping to an approved shutoff, sediment trap, branch turns 90 degrees, ground union, steel through the cabinet, flex connector to the appliance valve.

Good call

I hope you correct that potential bomb.

Yep. I corrected it about an hour after i saw it. Now its piped black from the gas valve to outside the furnace. I wont leave something running unsafe!! :beer:

I agree. There was enough slack in the flex, he could have at least pulled the nipple through the cabinet!

the nipple is the only good thing...lol

Proper gas connection

Picture is a little dark. Saw this today. I love the black nipple for a flex coupling.
