Draft hood
What it is
If your water heater has a draft hood then it is a natural draft water heater.
A draft hood is a flanged hood at the base of the flue pipe above the gas water heater tank (Figure 3).
Traditional gas water heaters with draft hoods are prone to spillage and backdrafting. They should be avoided.
