Oval water heater vent

[Joshua L. Frederick]

Is there an approved oval and/or wall stack water heater vent? Basement water heater vented up through exterior wall to the roof with an oval pipe.

Thanks in advance.

No, it was in the wall. Could barely see it in the basement. Attic wasn't accessible. I'm assuming the 1" clearance still applies, no? Seems like that would be hard to achieve in an exterior 2x4 wall.

Thanks for the reply.

Yes, 1 inch clearance, assuming it's a listed BW-vent.
