Venting Code No/Go

[cookster]

Looks like got vent heater thru the roof. Under 4' from over hang , even with over hang being 5''. Really hate go thru the roof.

If I understand your question correctly, you could go thru the exterior wall, 90 degree elbow up, and extend up above the roof. If your overhang is only 5", that should be easy to do, providing that you observe the venting requirements of your application (too many elbows or long flue runs prevent a proper draft).

However, the appearance of such an arrangement might convince you that straight up thru the roof is the shortest, least expensive and best looking choice. If properly installed and flashed, there should be no concerns about a roof penetration becoming a problem down the road.

As always, offered only as opinion

check with your building department, you may just need to extend it past the 5 inches, IOW a 12 inch pipe sticking out of the wall

MY boiler vent goes through the back wall of the garage and I have been thinking of putting it up in the roof. The big thing for me is the master bedroom is on the back of the house right where the vent is so I hear it all night when the boiler is running (power vent unit)

Roof installations are not hard at all. Cut hole, nail/gloo flashing to roof, insert vent, silicone the drip edge, put the cap on, done.

I go along with the others, go through the roof, it is really easy and as said, when flashed and sealed properly there will no leaks. I've not had any issues with mine and I really didn't want to cut a hole through my wall.

x2. It will look so crappy going out the wall it isn't even funny. It will take a cute little place and make it look like $hit.

Uh... ok....

Hehe, my post was for the OP. You, as a thread hijacker, are collateral damage.

This is what I did. I have little experience with plumbing when I put in a tankless water heater. I later found out I didn't plumb to code (1/2" gas line is what I did, didn't use correct flashing either, but plumber said it was "good enough" and that he didn't think code was really necessary there -- who knows?), but everything seemed to work fine.

Im going thru the roof. From what I was told fom heating / air guy they just put hole thru we ever convinient to them, only thing to avoid is comming out next to something. [such as corner]. Said power vent blows away from building.
