Combustible clearance

[mathew stouffer]

Is this type of piping considered combustible or is this set up ok? It is single wall and the water line is contacting the vent.

Thanks
Mat

Combustible.

Needs 6" clearance to the single wall.

If the single wall were changed to Type B Gas Vent, it would only need 1" clearance.

Looks like they made an extra effort to clear the clearance requirements for the draft hood, then installed single wall and forgot about its clearances. :rolleyes:

Is that an aluminum dryer vent section? Looks like it is in your pic. If so, it needs to be replaced with a suitable material (single/double wall galvanized)

Matt, the water supply hoses may have steel mesh on the outside but there is still a rubber hose beneath the mesh so like Jerry said, you need at least 6 inches from that flue pipe. And that vent pipe does look flimsy.

What's with the CO detector right next to the vent hood?

As Jon Randolph points out that is not the right material for venting the heater. I see this a lot on home owner self installs. They buy the dryer vent tubes since it is right next to the galvanized vent tubes. Most home owners told me they went this way due to it was already in a round tube where as the galvanized vent tubes needed to be put together.

I now see why here in Illinois why they do not want the heaters plumbed in with flex connections. The water heaters here are to be hard piped, gas and water.

Thanks guys. I was curious about the piping, the rest of the install was a DIY. No pan, no discharge line, wrong venting, and the co detector was under the diverter. There were a few other jems but you get the pic.

Thanks
