Water Heater Vent Pipe

| I just tested a water heater with an aluminum vent pipe connecting the
draft hood to the B-vent. If I understand correctly galvanized or
stainless pipe is required to meet code. Is this correct or is
aluminum ok?

I don't think there is any material requirement for the connecting pipe. I'm
using a 24" flexible appliance connector (Selkirk Metbestos brand) and it is
all aluminum, as is the inner lining of the B vent itself. Wood burning devices
use stainless liners.

I've had a 4" aluminum flex pipe on my propane water heater for almost
30 years. It connects to a 4" galv tube before joining the boiler
stack. If alum is not to code, I can't imagine what the reasoning is.
