Thats what I was wondering. I didnt realize they made the same water
heater with a 3 and/or 4 inch connection.
I too could stand a little correcting.

just curious here Bob, do you ever seen super old venting done with
transite? That's the norm around these parts. most all resi- gas
venting 20 yrs or older is 4-5" transite.

bubba, even if he water heater had a 3" draft hood, he could still adapt it to
4" bvent. His question was if he could vent the single appliance up an
interior 4" bvent. Simple.

You still havn't amswered by telling us how you would vent his appliance?
Would you replace all the bvent with 3", run a 3" liner down the bvent? What
would bubba do? Maybe get the customer to replace the thermostat HAHA

bubba I would run circles around you in the service dept! ;)

Can't tell a thing without actually *SEEING* the application, and
installation.
Under most *normal* circumstances, for what has been described here I would
be looking at 3in B-Vent, unless the manufacturers instructions specified
otherwise. If the vent pipe is too big, you will have condensation problems.

I don't believe I would want to go there.
