Our gas water heater is in a closet that opens into the garage. When I
had it replaced about 5 years ago, the plumber said that the codes had
changed and the water heater had to be installed on a platform that
elevated it a certain distance above the floor. He said that flammable
fumes in a garage were heavier than air and would float close to the
floor. This implies that if the water heater is 18" above the floor
then it will be less likely to ignite fumes.
