How do you seal the gap around a water heater vent pipe?
These gaps should be sealed with lightweight aluminum flashing and special high-temperature (heat-resistant) caulk. Before you push the insulation back into place, build a metal dam to keep it away from the pipe. Use the same technique for masonry chimneys.
How do I know if my water heater is Backdrafting?
Testing for backdrafting
- Cup your hands around the draft hood (the cone-shaped vertical pipe at the top of your water heater) and see if you feel warm, moist air.
- Place a small mirror by the draft hood, and check back to see if the mirror fogs, which would indicate the presence of moist air.
What causes the hot water tank Backdraft?
The main reasons for backdrafting at the water heater are the poor vent installation and obstructions found in the vent pipe. This problem affects mainly the atmospheric gas type water heaters that use natural convection to remove the combustion products, known as exhaust gases.
What is a water heater vent connector?
The vent connector is the thing that connects the water heater to the vent. It usually runs more horizontally than it does vertically. It’s important to know the difference between these two because the installation rules aren’t the same.
Can you tape water heater vent?
Strong tape does the job. I used it to attach a insulated blanket on my water heat, adheres well, hold strong. Tape is designed to seal insulation jackets for maximum system efficiency. I also used it to relocate a heating vent in my kitchen.
How hot does water heater vent pipe get?
The flue gas temperature will be around 160 F when the water heater is new if it is set to store water at 140 F. The flue gas temperatures can reach over 350 degrees F as scale builds up.
How can Backdrafting be prevented?
Most of the time, this is accomplished by cutting an opening in the roof and refraining from opening any windows or doors on or below the fire floor until conditions have changed. This means that no search and rescue can occur and no water is being put on the fire until the vertical ventilation can be completed.
How do you test for Backdrafting?
To check for proper draft, I simply cup my hands around the draft hood without actually touching it. If the water heater is backdrafting, I’ll feel warm, moist air coming out of the draft hood.
What creates a backdraft?
A backdraft is caused by the sudden introduction of air into a fire that has depleted most of the available oxygen in a room or building. Since a fire requires air, fuel and heat, the latter two must be present as well.
What happens if a water heater is not vented properly?
A vent connector is the thing that takes the exhaust gases from the top of the water heater (draft hood) to the vent. If a vent connector isn’t properly installed, the potential for the water heater to backdraft increases.

The vent is the metal thing that goes from the room that the water heater is in and rises up through the roof. It’ll typically be a straight vertical run of UL-listed double-wall class-B vent. The vent connector is the thing that connects the water heater to the vent.
Why is my water heater leaking from the overflow pipe?
