[Erby]

Does it apply to a metal flue from a propane gas log set?

Probably not. I believe the 10-2-3 is a masonry chimney thing.

2 feet higher than anything within 10 feet still applies. The primary consideration here is draft not fuel, although there are minor differences for the actual height above the roof for different fuels.

B vent:

1 foot above a 6-in-12 roof

2 feet above a 9-in-12

4 feet above a 12-in-12

L vents at least 2 feet above the roof

It's fine.

This is for GAS vents:

Bob K., this chart says 4 feet up to and including 12 in 12, 5 feet for steeper than 12 in 12.

No, it's a gas vent.

If the vent is 12" or less, and it has a listed cap, the height of the lowest discharge opening above the roof is determined by the roof pitch.

OK,

So, it's a Heatilator brand 48" direct vent pipe. It has a 4" inner opening and the pipe is 6-5/8" in. outer diameter. The bottom of the opening is 5.1 times its diameter above the roof which makes it 34.22 inches to the opening. It looks like about a 9:12 or a 10:12 pitch which requires a 30inch height.

As I said, it's fine.
