Wake Forest NC Home Inspection

By

We completed a Wake Forest NC Home Inspection today on a brand new custom-built home.  Very nice house with the typical flaws and three worth mentioning.  1) soil and foundation wall damp in crawl space due to discharge of a downspout combined with a flat lot, 2) plumber ruined some of the blocking between the floor joists to run drain pipes, 3) water heater flue pipe was too close to the side wall of the house - this is a safety issue due to a potential disruption of proper venting.  Here is what we said about that in our Wake Forest NC Home Inspection report:

Wake Forest Home Inspection


Safety Concern    Gas water heater vent pipe is too close to the side of the house.  Generally accepted building practices call for the pipe to extend n

ot less than 2 feet above any portion of a building within 10 feet horizontally.  Current configuration could affect proper venting of the exhaust gases.  Consult with the local building inspector for specific information on how to correct this issue.

Jayme, I am pretty sure that you will find that the "2' above, 10' away rule" does not apply to gas vents.  There are some concerns like you indicate as to how close to the side wall it is though and in this case it should go above the roof line 2 feet min.

These are the instructions from a popular manufacturer of these gas vents:

 

"Downdrafts are generally caused by the system's termination
being too close to an adjacent wall, parapet, or other structure. If the cap is within
eight feet of such an obstruction, it must also be at least two feet above it. Also insure
that the top is at the height prescribed for your roof pitch in Table 2. Inadequate
combustion air is also a major cause of downdraft problems."

 

Another manufacturer states 8' minimum from a sidewall so the ten may be off a hair.  Yes to correct it, they can extend it up 2' past the height of the roof next to it.  Thanks for your comment!
