How do you check a water heater burner for operation?

How to inspect the burner flames. A soft blue flame is the sign of the correct gas combustion. Use the viewport at the bottom of the water heater to examine the burner flames, at least twice a year. If you see blue tips with the yellow inner cones, it is still OK.

Is the burner on a hot water tank sealed?

For safety, hot water tanks now have a sealed inner door to the combustion chamber. You will have an igniter connected to the burner to light your pilot. There are several ways that companies seal the burner chamber.

What kind of heater has a sealed combustion design?

Sealed combustion designs are available in most current 90% AFUE efficient (or higher) forced air furnaces, as well as a variety of central hot water heat boilers, wall-mounted gas heaters, specialty tank type water heaters, and also a variety of tankless water heaters.

Do you need a permit for a sealed combustion heater?

Sealed combustion equipment should be installed by a licensed professional, and requires a permit from the local building authority. The permit provides for an onsite final inspection to make sure the work was performed properly, and to ensure homeowner safely.

Can a thermocouple be replaced on a hot water tank?

What to do if your water heater burner stops working?

Proper supply of combustion air is mandatory, especially if the water heater is installed in a closed or confined area. If the main burner or burner orifice is clogged, make sure to unclog them or replace the orifice. If excessive heat build-up inside the chamber, the thermal switch will trip and shut down the whole water heater.

Where does the gas burner go in a water heater?

Every gas-powered and tank-type water heater uses the gas burner located in the combustion chamber to heat water, pilot light or electrode to light the fire, and a gas control valve to deliver natural gas or propane. During the burning process, exhaust gases are vented out, either naturally (convection) or forced (electric blower).

What makes a gas water heater not catch on fire?

Most of today’s gas water heaters are equipped with the FVIR or Flammable Vapor Ignition Resistant technology and unique flame-arrestor feature, which prevents the flame and burning vapors to escape the combustion chamber, risking the open fire and potentially – explosion.
