Checking that the Burner End Cap is Secure
The burner end cap is assembled to the burner chamber at the factory. It is always a good idea to confirm
that the screws are tight. To do so, hand-tighten (in an alternating pattern) the four knurled screws holding
the burner end cap to the burner chamber. Tightening them in an alternating pattern (diagonally opposite
nuts) will allow the o-ring to form a good seal. See the figure below for the location of the four knurled
screws. Tighten them only hand tight.
