Had a clietn yesterday ask about restrictions on gas water heater usage. Their particualr house model is the only one in the new development that has electric water heaters. The house has gas service. They apparently asked to have the gas water heater and were told by the builder that they could not in their model.
I looked through my code books and cannot find a reason that seems to support this. The installation is a single story home, water heater tank in a garage closet. I cannot see a difference in this model from the other similar models that had a gas unit in the similar garage closet (closet was properly ventilated, etc.) Anyone know of a limitation that would apply in this type of situation?
