With the heat coming out the bottom, makes me wonder if you've got a

chimney?

Might be choking the flame for lack of oxygen?

Good point Chris.

To test for a blocked flue hold a burning match under the draft hood while
the main burner is burning. If the flame draws toward the chimney all is
fine. If the match blows out, you have a draft/venting problem.

More in that vein: A number of times we have seen the inner flue
passage *inside* the heater collapse. The pressure of the water
crushes a tank core weakened by age and rust.

The flame burns out because of lack of oxygen. Usually gives off
a very bad odor when it does. This type of failure may not show
on the draft hood test.
