2. Slowlydecreaseopeningsofairshuttersonburnerstogiveasoftblueamehavingluminoustips,
thenslowlyincreaseopeningstoapointwheretheyellowtipsdisappearandahardblueame
is obtained.
PLACING LAVA ROCK ON GRATES (FOR AMLB SERIES)
Open the lava rock bags and place rock evenly on grates. Do not cover the grates with more than two
layers of lava rock. DO NOT PUT MORE THAN 5 LBS. OF ROCK PER BURNER!
PLACING RADIANTS (FOR AMRB SERIES)
After the unit is unpacked and installed, place 2 radiants above each burner. Install each radiant
engaging the notches on the top assembly. Refer to the exploded view in this manual for orientation
of the radiants.
BURNER OPERATION
Eachburneriscontrolledbyanindividualhigh-low,on-offvalve.Aninnitenumberofbroiling
temperatures may be obtained by turning the burner valve knob to any position between high and
low. It is possible through this arrangement to have a high heat or searing section, while having a low
heatnishingorholdingsection.Forthesearingoperation,setthevalvesforthesectionataposition
of"HI"orclosetoit.Forholdingornishing,setthevalvesclosertothe"LOW"positiononthedial.
You select the heat pattern you like, and set the valves accordingly.

GENERAL OPERATING INSTRUCTIONS
WATER PAN / DRIP TRAY
The water pan is located at the bottom of the
unit, and is easily removed from the front of the
unit. Water should be added to the water pan
and replaced as necessary. The water pan helps
preventareupsandcatchesgrease.
LIGHTING
Whenbroilerisrstlit,itwillsmokefor
approximately 20-30 minutes until the
preservation oils and impurities are burned off.
SEASONING THE COOKING GRATES
Set the heat control switch to the low position and
preheat for about 15 to 20 minutes. Using a cloth,
spreadathinlmofcookingoiloverthetopof
thegratesurface.Allowthelmtoremainonthe
grate for about 5 minutes. Wipe the surface clean
andapplyanotherlmofcookingoil.Wipethesurfacecleanagain.Thebroilerisnowreadyforuse.
The oil may tend to smoke - this is normal.
BROILING
Turn valves on and pre-heat unit on "HI" before attempting to broil. You will have to experiment with
the grill settings and the valve settings for your particular food products. We recommend that you set
the grate at the full tilt position to start. This position allows the grease to run down the grate into the
greasetray,reducingareups.Checkwaterpansfrequentlyandaddasufcientamountofwater
when necessary. Hot water vapors rising from the water pans and through the combustion chamber
helpsreduceareups.Exercisecarewhenusingyourbroiler.
TILTING THE GRATE
Raise or lower the grate to the next step by lifting the grate at the back of the charbroiler where the
grate rests. Use potholders or gloves to reposition.
CHARBROILERS ARE HOT! NEVER ATTEMPT TO CHANGE THE GRATE POSITION WHILE
FOOD PRODUCTS ARE COOKING. FLARE UPS CAN OCCUR UNEXPECTEDLY. TURN OFF
THE CHARBROILER AND ALLOW IT TO COOL.
CLEANING
Clean regularly. Remove grate section to sink for washing. Brush out carboned particles. Remove and
wash water pan. Wipe exterior surfaces with detergent and a cloth. A non-abrasive cleaner can be
used on caked areas.
AIR INTAKES IN BOTTOM
Air for combustion enters from the bottom of the unit.
Do not obstruct this area.
Water Pan / Drip Tray
Fill with water before operating
to prevent flare-ups and
catches grease.
