Forum Title: Common Vent Water Heaters
Can multiple natural gas water heater flues be combined into one flue if they are of the same type of water heaters? I understand this might be dependent on the jurisdiction but do any of you have experience with this? Thank you,

they can combine. but the flue sie out the roof must change 1 1/2 times the size of the smallest unit that would be 4 1/2'' flue...they dot make it,,,so i would be 6'' double wall vent pipe
