Default Clearance?

This is a single wall vent pipe for the water heater. The clearance appears to be not enough for this pipe am I right to think this? Any help?

Default Re: Clearance?

1" minimum clearence is required from combustible material, If that collar is metal that would be acceptible.

If the pipe is sngle wall, clearance to combustibles needs to be a minumum of 6 inches. 1 inch clearance is for B-vent (double walled)

I dont think a single wall vent is supposed to enter the attic at all. Should be a b-vent.

"The water heater vent consists of a single-wall pipe in the attic space, which is prohibited. Service by a licensed plumbing contractor is recommended."
