Installing DVL. A long section is heavy and installed at a 45, so I want to put in a hanger. I currently have it hanging off a couple of ss hose clamps and some ss wire. I like the clamps, but I don't know about the wire. It's very adjustable, but not sure how it'll last. I was thinking of the plumber's strapping, but not sure.
Any experience? Best practice?
Thanks.
 
Plumber's strapping will work just fine. Use Zipscrews on the pipe
& deck screws if you're attaching to wood framing members.
I've done it many times. Attach one end to the framing & bring the strapping
down around the pipe & back up to the framing in ONE piece.
Make sure you attach to the pipe in a couple of places, & if
you need to run more than one strap, it'll be even better.
Generally, the installation guide that comes with the pipe sections will indicate
the preferred method.
 
I have never seen DVL installed in this manner! It has to look bad, no offense.
Typically the elbows will go up above, near the box. If its secured to the adaptor at the box, and secured at the stove as well as each joint, it should be fine. If you secure it at each end you can then push your slip up nice and tight and secure it last. It holds things nice and tight. There should be no need for hose clamps and wire.
 
I agree it's not very aesthetically pleasing, but when you run a long section at a 45 degree angle, you don't have much choice.
Most venting/chimney installation guides will dictate that an offset section requires additional support for safety reasons.
IIRC, he's using the DVL in a basement on a central heating system as a part of an all fuel venting system.
I did the same thing on my oil boiler...Safety & functionality trump looks in a basement install.
 
When I test fit the pipe, it held without the hanger. Staying up in the air relies on that adapter I talked about earlier. There are 4 sheet metal screws under tension holding up the pipe, far as I can see. The big slip section is heavy.
 
How much offset are we talking here and what is it venting? Any chance the appliance could be moved to prevent such a large offset?
 
It's a pellet boiler. Each end is a 45. I think the geometry is what it is.

Then by all means, strap it up. I didn't realize it was a utility situation.
