I am building a house for my daughter and her husband and to save some money I'm doing pretty much everything. My question is I need to vent two gas water heaters (50 gallons each My son-in-law was adamant about having two.)Each vent is 3" and I would like to vent both to a common vent but I'm not sure what size the common vent should be. I will be venting through the roof.
No announcement yet.
