generator exhaust

[diandtom]

Does anyone know where I can get some flex pipe to run the generator exhaust away from our fiver? I need a 1/2 inch about 10 feet long.

Have you looked into a Genturi? I would recommend you not use a pipe that will fit tight to the present exhaust pipe. A little larger will do what you want just fine if not better. Be careful if there are any combustibles that the flex pipe might come in contact with. You may be able to use 1" flexible metal conduit.

10 feet of 1/2 inch tube?!? And flex besides.

How much restriction and back pressure is this going to put on the engine?

Wow,never saw an exhaust that small,1/2".

If you want flexible exhaust hose, I suggest the ones used in service shops to duct exhaust outside. They are a rugged rubber compound. You can also use the metal flex stuff used to customize exhaust systems (available in many auto parts stores or JC Whitney) but it doesn't last all that long.

You really only need a few feet of flex extension and then can duct it into a PVC pipe because the gasses will be cool enough by then. However, you want a larger a diameter than 1/2 inch, as the other have said. I'd say 1.5" would do it.

Go to Home Depot and get some Greenfield. If Home Depot doesn't have it, try an electrical supply store. I have a piece about 12' long and being it is flexible I can direct it wherever I want.

K-Star... what is "greenfield"? Some sort of flexible pipe or tubing? I'm not familiar with the term.

[K-Star]

greenfield is the flexible metal sheathing used in place of Romex in the installation of electrical service in the walls. Primary used in commercial applications. Unlike Romex that has the wires contained within the sheathing, the wires are separate and then is pulled thru the sheathing. It is not used in place of conduit which is a rigid tubing.

Thanks, K-Star. Now that I hear the description, I know that I've got several feet of it sitting in my shop. Just never heard that name for it.

....It will work as long as it doesn't get too hot and you don't roll it up tight always.....keep extra on hand and a fine tooth hacksaw and vice grips.....there is a hard gray plastic tubing also with slip joints that will stand heat....check code on side.....we use it for gas furnaces that make water vapor when on burn cycle....geof kaye

I got some 1/2 inch at Lowes and it seems to work ok. I am using a short piece of copper pipe and the copper pip fits over the generator exhaust well.
