REPLACEMENT PROCEDURE:
ROTISSERIE ORIFICE:
STEP 1:
Remove all Grills, Warming Racks, Briquette Trays
and Grill Burners from the grill’s firebox.
STEP 2:
Detach the Rotisserie Panel by removing
the holding screws located at each top corner of the panel. (Note: ALX2-56 BFG units
have two separate panels - remove screws
from both panels)
STEP 3:
To access the burner’s orifice behind the
panel, “tilt” the panel forward. The panel can
be supported by the bottom tabs, as you tilt
the panel.
IMPORTANT: The Rotisserie Burner has a flexible,
stainless steel, 3/8” gas tube. Flex the tube forward slowly
towards you. (It’s quite strong).
(See figure at right - ALX2-42 shown).

STEP 4:
Remove the Rotisserie orifice
with a 1/2” open wrench from the
3/8” compression elbow fitting.
Install the replacement orifice for
the proper fuel you are replacing.
(See orifice kits at the end of this
booklet).
Tighten the orifice to ensure no
leaks will occur.
IMPORTANT:
Verify that the igniter cable, located
opposite to the orifice assembly, is
properly secured before reassembly
of the panel.
STEP 5:
Reassemble the Rotisserie Panel by reversing the procedure. Tilt the panel backwards, and insert the
top back into the rear hood assembly. Fasten the top 2 screws at each end to secure the panel in place.

GRILL BURNER ORIFICES (SEARZONE™) :
STEP 7:
If your grill has a SearZone™ burner, use a ratcheting wrench, a 3” driver extender and a 1/2” socket,
remove the orifice from the inside of the grill. The SearZone™ orifice is located just below the burner’s
igniter electrode. The orifice is attached to a 3/8” elbow fitting directly in the firewall (between the front
panel and the firebox). It is not attached to the gas valve as the U-Burners.

STEP 8:
Remove the Smoker Tray and Grease Tray Assemblies out of the grill’s body.
STEP 9:
Using a 7/16” open wrench, loosen the compression
fitting from the 1/8” aluminum smoker gas line. The
smoker orifice assembly is attached to the firewall
with one screw, remove it.
NOTE:The aluminum gas line is very soft. Carefully,
bend the gas line forward and remove the orifice assembly. If the gas line is NOT free after loosening
the nut, continue to un-screw the nut until the assembly is free to be removed. The nut along with the
compression ferrule will remain with the pipe.

STEP 10:
With the smoker orifice assembly removed, remove the
orifice using a 9/16” wrench (for the elbow’s body) and
a 7/16” for the orifice itself.
Replace with the proper fuel you’ll be using.
(Refer to the assembly at right as a guide)
STEP 11:
Reinstall the orifice assembly into the grill by following
these last 2 steps in reverse.
DO NOT over tighten the compression fitting to the
1/8” aluminum gas line.
SIDE BURNERS: (ALX2-56 MODEL ONLY)
STEP 12:
Remove the side burners’ cover, cooking grate,
burner exterior and inner cap.
STEP 13:
Looking directly over the burner, locate and
remove the orifice from the bottom of the
cone-shaped burner body. Use a 10 mm
socket, driver extension and ratchet wrench
for this procedure.
STEP 14:
Replace the orifice with one for the proper fuel to be
used. DO NOT OVER TIGHTEN!

GAS PRESSURE REGULATOR CONVESION:
STEP 15:
The ALX2 grill is equipped with a Maxitrol™ pressure regulator
that is suitable for LP or NG fuel regulation. To convert the
regulator to proper fuel, remove the brass cap located in it’s
center.
CAUTION: There are several components in this regulator assembly. Be careful with the gas sealing washer, the plunger
and plunger’s spring located inside the regulator.

CAP
STEP 16:
Locate the black plastic plunger inside the brass cap. The plunger provides the right pressure setting at
the regulator outlet by changing the spring pressure.
Pull (pop-out) the plunger out of the brass cap, reverse it’s direction and re-insert into the cap with the
proper fuel desired pointing TOWARDS the regulator spring and body.
Reattach the brass cap into the regulator body and tighten securely with the gasket.
STEP 17:
If the unit is being converted from NG to LP, the LP kit will include a 1/2” NPT X 3/8” ODF reducer (hose
adapter) that needs to be installed on the gas inlet elbow attached to the regulator.
Install with reducer with a gas approved plumbing seal Teflon® paste or gas approved yellow Teflon®
tape.
NOTE: The conversion is now complete. Pressurize the gas line with the correct fuel for the application
and check for leaks before lighting up the grill. Before using the grill, all the grill’s surface burners will
need to be adjusted for proper combustion and low flame settings. Refer to the following steps for adjustment.
GASKET PLUNGER
PLUNGER DETAIL:
The plunger LP side has a WIDE
disk on the end. The NG (NAT) side
does not. The side pointing to the
body of the regulator determines
the fuel to be used in the grill.

AIR SHUTTER ADJUSTMENT:
Adjust the “AIR SHUTTER” to regulate the amount of air that enters into the burner for combustion.
Loosen the set-screw of the air shutter. Reinstall the burner. Make certain that the burners are sitting
properly on the orifices.
Light the burners and adjust according to the following directions:
1. Turn the valve on “HI”, light the burner and allow it to “WARM UP” for 10 minutes.
2. If the flame is yellow, indicating insufficient air, turn the air shutter to allow more air to
the burner.
3. If the flame is noisy and tends to lift away from the burner, indicating too much air, turn
the air shutter to reduce the amount of air to the burner.

LOW HEAT SETTING ADJUSTMENT:
NOTE:
ADJUST THE LOW HEAT SETTING
WHEN CHANGING FUELS OR WHEN
ALTITUDE OR OTHER ENVIRONMENTAL FACTORS ARE CAUSING
POOR, LOW HEAT, PERFORMANCE.
ADJUSTMENT STEPS:
1. Follow lighting instructions by setting the control
knob on “HI” and allow the burner to preheat for 10
minutes.
2. Turn the control knob to “LOW” and wait for the
burner temperature to drop and stabilize.
3. Attempting adjustment at any setting other than
LOW can create a dangerous condition.
4. Remove knob by pulling straight away from control
panel.
5. Insert a small blade (1/8” wide) screwdriver into the
valve stem to begin the adjustment.
6. Turn counter-clockwise to INCREASE the low heat
flame, or clockwise to DECREASE the blame height.
(see figure at right).
