Through Wall Venting

I inspected a 1986 built home today that was converted from all electric (baseboards & water heater) to a gas boiler/hot water in the early 90's. I've never seen through wall venting like this before. I'd welcome some critical eyes taking a look at this and opinions on this installation.

Hi,

I see those water heaters all the time. the fiberglass packed against the exhaust vent might have violated the manufacturer's rule, although you can usually put your hand on those things and they're just warm because the cold air comes in thorugh the outer ring and the hot air goes out through the center.

It's a regional thing, I guess, but around here, because it's earthquake country, there'd need to be flexible connectors as well as full-circumference strapping top and bottom third of the tank. Outlet souldn't have been reduced.

I'll let Kurt or one of the guys who sees boilers every day speak to that boiler.

ONE TEAM - ONE FIGHT!!!

The venting system is very common around here. But the venting out under the dect is a no/no. The clearence to any opening (window, door) must also be 4', and looking at the pictures it seems to me that they might be closser than that. The insulation packed around the pipe is also wrong and will usually be called out in the installation manual. It should be called out as improper installation and venting. No questions asked.

Well thats my 2 cents.
