SERVICING AND CLEANING (Cont.)
Convert/Check Main Burner Orifices
Note: It may be necessary to remove the rotisserie
rod before beginning this procedure.
1. Remove the cooking grids and vaporizer panels and
set them aside.
2. Remove the burners (see BURNER REMOVAL
section for step-by-step instructions).
3. Use a
1
/
2
" hex deep socket nut driver to remove the
exposed orifices. Access the orifices through the
holes in the forward firebox plate inside the grill (see
Fig. 33-2, A). Check orifices. If needed, replace all
with the correct orifices for the new gas.
Alternatively, the orifices can be accessed through
the inside of the control panel if the proper tool is
not available (see Fig. 33-2, B). This allows a
1
/
2
"
open-end wrench to be used instead of a
1
/
2
" hex
deep socket nut driver. To open the control panel,
see the CONTROL PANEL REMOVAL section.

CONVERT GAS TYPE / CHECK BURNER
ORIFICES
CAUTION: Make sure the grill is at a safe temperature
and isolated from gas and electrical
supplies before beginning.
For your safety, exercise caution, and make sure you
have adequate hand protection, such as gloves, when
handling metal parts.
Apply Conversion Label
This grill comes from the factory configured for one type
of gas as marked on the label behind the control panel.
When the grill is converted, the label for the new gas
(included at original shipping) MUST be filled out and
applied next to the existing label mentioned above.
Convert Regulator
The gas regulator, located beneath the grill, must be
set for the type of gas used to fuel the grill. To check the
regulator setting, remove the cap in the center of the
regulator (Fig. 33-1, A). Holding the cap vertical (see
Fig. 33-1, B), the letters at the bottom of the plastic stalk
indicate the gas type for which the regulator is currently
configured.
If the text on the bottom of the regulator stalk does not
match the gas type connected to the grill, remove the
stalk from the cap, invert, and replace into center of cap.
Replace cap on the regulator, screwing down until snug.
Note: Models to be connected to household propane
or natural gas lines require the regulator. For
models to be connected to L.P. cylinders, the
regulator is optional.
Convert Gas Orifices
When converting the grill to a different gas type, each
burner’s orifice must be replaced with the corresponding
orifice for the new gas.
See
MODEL SPECIFICATIONS TABLE, Table 1 to
determine the proper orifice sizes for each burner.
See the following sections for details on orifice
conversion.
Important: It is critical to the operation of each
burner that its orifice be fully inserted
into the center of its orifice opening.
WARNING
HAZARDOUS OVERHEATING WILL OCCUR
IF A NATURAL-GAS ORIFICE IS USED WITH
PROPANE GAS.
Connect To New Gas Supply
Plumb the unit as appropriate for the new gas supply.
(Additional components may be needed for your specific
setup.) Be sure to leak test at all connections.
