Our new stove seemed to have
a problem with leaking smoke and heat out of the top right burner in
the back. After a few minutes of research we found out this is normal
and all stoves have this vent hole to prevent explosions, but our old
one never seemed to leak any smoke.
It only took about 10 minutes
to take the old grid thing out and make room for it in the new vent
hole, which seems to have stopped the leaking smoke problem.
