MAX. DIMENSIONS (C)
Approximate measurements
The maximum dimensions of the burners are given in
(C).
Note that if you need to examine the combustion head,
the burner must be pulled backward on the slide bars
and turned upward.
The maximum dimension of the burner, without the
cover, when open is give by measurement H.
