Replace the Gas Griddle Orifice—
if so equipped
• Remove the Griddle's Grease Tray, Griddle Plate and
Griddle Frame. These items are not held with
fasteners, so they should lift up and out easily.
• Remove the screws on each end of the Flame
Spreader, while paying attention not to drop the
spacers inside the cooktop / rangetop area.
• Remove the Cover Plate with four (4) screws, which
covers the Griddle Burner's venturi at the bottom of the
Griddle Box.
• Lift out the Griddle Burner.
• Use a 1/2" deep-well socket to remove the Grill hood
orifice. When installing the LP orifice, take extra care
not to bend the sheet metal orifice bracket.
• The LP orifice is a #57 drill (stamped "57"), which is
sized to produce 13,000 BTU/hr. [3.81 kW], using
Propane (LP) Gas. The orifice diameter could also be
1.10mm; in which case, the hood orifice could have a
"110" or "1.10MM" stamp.
• Pre-adjust the burner's air shutter to approximately
75% closed (approximately 0.20" opening) position and
re-tighten screw(s) using a 1/4" nut driver or wrench.
• After the orifice conversion, gas leak check, and re-
installation of the griddle burner, check that the ignitor
electrode tip spacing to the surface of the burner
(tangent point) is approximately 0.105". There is some
movement available in the burner mounting, on each
end, to adjust this spacing if needed.
