Question about water heater flame color and size
by Melissa R.
I have a natural gas water heater that when heating the water is producing more dirt than usual and it is smoking. What the??? I called my utility gas company, as I thought it might be a dirty gas, but they are saying it is my water heater.
Is that correct? I should look at the flame color and the size? I checked that and I have noticed that the burner flame colors are changing, blue and yellow. And the size is changing.
My question is... what is the perfect flame size and color of the burning natural gas?
Should I call a technician or is that DIY home project.
