It was a voluntary recall. I have done many of the recall repairs, not
hundreds, but close. They involved heaters manufactured between 2000 and
2007. It involved a gasket replacement and gas pressure adjustment.
That number represents a small portion of the total number of heaters
out there. They are sealed combustion, direct vent units.
You might thinking of unvented units. I don't like installing them. I
try to discourage people from installing them.
