Surface Burners - 300 Series Ranges
The surface burners on the 300 Series range are secured to the cooktop
by two screws. Photo A at right shows the five burner model with grates
removed and burner caps in place.
To remove and replace any of the burners first lift off the burner caps as
seen in photo B.
Using a 3/16" nut driver turn the screws counterclockwise to remove as
shown in photo C
The burner can then be lifted away from the cooktop providing access
to the mounting screws for the Rrifice Kolder Dssembly, igniter tip and
burner orifice as seen in photo D.
