Looking for an opinion on the use of a flexible gas appliance connector used to supply a furnace. My memory tells me this is not allowed but wanted to check. From the shut off valve to the furnace has to be hard pipe? Lack of sleep not helping my brain…
In CA, all furnaces and water heaters are connected with flexible appliance connectors. Perfectly acceptable as long as they are installed per building codes and manufacturers installation instructions.
Bob, you mean a picture like this? Just found this one, flex line entering knock out of furnace… underneath the furnace. Horizontal install in an attic. Go figure. The second pic is the hooks supporting the furnace screwed into the rafters, they are all bent and pulling out. An all around great install, not!
Yep the vibration can cut the flex.
Also like the vent at the powerfan.Hope its not the rangehood…instant fire.Even ignoring the mold created from a bath fan the plastic may get caught up in the thing…
Does not apply here Cam other than about protection which I have never seen at the knockout.
Maybe just me but Damn codes are boring to read and take 1,000 words to say what we all said in one sentence.
That’s why I like the forum so you guys can interpret for me into simple language.
When installed outdoors, CSST shall be protected from mechanical damage. A conduit or chase is required for installations in exposed unprotected areas within 6 feet of grade. Conduit shall be supported with proper size pipe hooks, pipe straps, bands, or hangers.
Protective coating must remain intact outdoors. Mechanical joints and associated exposed metal tubing shall be wrapped or protected by shrink sleeves. Appropriate measures must be taken to shield CSST from corrosive environments such as exposure to acid or chloride based cleaning solutions for brick or masonry.
Where passing through an outside wall, CSST shall be protected. CSST must be sleeved where passing though.
