What comes out of a water heater vent?
All water heater venting systems use a vent duct or pipe—also called a chimney or flue—to bring exhaust gases from the water heater to the outdoors. The duct may be metal or plastic, depending on the type of vent system. In addition to venting, gas and propane water heaters need an air supply for combustion.
Where to cut the door on a hot water heater?

What should I do if my water heater flame is not working?
If the venting system is blocked, clean it and make sure that air and flue passageways are free of deposits and debris. If the problem is with the high gas pressure, call the utility company.

Where does the power vent go on a hot water heater?
