4. LIGHTING INSTRUCTIONS
HHP and HHPS Gas Open Burner Ranges are furnished with either a pilot safety valve or a standing pilot
(not available in the European Community). Please follow the instructions for your unit.
Operation of the gas valve pilot:
1. Turn knob on the main gas valve to the pilot position
2. Depress knob to start gas flow to the pilot valve
3. Light pilot valve
a. Using a match or taper
4. Hold in knob for 15 to 30 seconds to heat up the thermocouple
5. Release knob and turn to the desired gas flow position
a. If pilot goes out repeat steps 1-4, some thermocouples will take longer to heat up
( NotAvailable in the European Community )
The pilot lights on the broilers have been set at the factory. A screwdriver may be required for the first lighting
to adjust the flame for your elevation.
1. Turn off the manual shut off valve and wait 5 minutes to clear the gas.
2. Turn all knobs to the "OFF" position.
3. The valve can be accessed through an opening in the front panel or remove the cooking grates and
light the pilot from above.
4. Turn the manual shut off valve on.
5. Hold an ignition source (match) to both openings on the pilot tube. When the flames are established,
remove the ignition source.
6. Turn the burner knobs to “ ”. If the burner does not ignite, promptly open the pilot valve more. If the
pilot flame appears larger than necessary, turn it down and reset burner ignition. The pilot flame should
be as small as possible but large enough to guarantee reliable ignition of the burners when the knobs
are turned to .
If the pilot light should go out for any reason:
Promptly shut off all gas at the manual shut off valve.
Turn off all knobs and pilot valves; wait 5 minutes to clear gas.
Relight following steps 4 through 6 under
Since the burner is lit from constantly burning pilot, turn knobs to "HI" to put the unit in operation; then adjust
to any desired position between "LO" and "HI".
To light burner, turn knob to "max." then back off to the desired flame level. The range of adjustment is
virtually infinite between high and off. (At the small flame, there is a pre-set low).
When the broiler is first heated, it will smoke until oil used in manufacturing, preservation and dust from
storage and shipping are burned off. An hour at "max." on all burners is usually sufficient.
Turn knobs off and let cool
For first cooking, set the grates at maximum tilt position and preheat before broiling. You will have to
experiment with knob settings and grate position for each particular item.
Keep the grease/water pan with sufficient water to cover the entire bottom.
Clean regularly. Grates may be removed for washing in the sink. Brush out carbonized particles.
Thoroughly wash the grease/water pan.
Never attempt to move a grill section while cooking. An unexpected flare could cause severe injury. Turn off
the unit, let it cool and use potholders and/or gloves to reposition or remove. The space between the legs at
the bottom admits combustion air. DO NOT BLOCK THIS SPACE.

European Community:
If adjustment becomes necessary in the field, it should be done by a factory authorized and trained
technician who should seal the screw after the adjustment to safeguard against un-authorized
tampering by the end user.
For efficient burner operation, a proper balance of gas volume and primary air supply must be maintained
which will result in complete combustion. Insufficient air supply results in a yellow streaming flame. Primary
air supply is controlled by an air shutter on the front of the burner.
Loosen the screws on the front of the burner, and adjust the air shutter to just eliminate the yellow tips of the
burner flame. Lock the air shutter in place by tightening the screws.
All burners are lit from constantly burning pilots. Turning the valve to the desired flame height is all that is
required to put the unit in service.
Do not permit fans to blow directly at the unit. Wherever possible, avoid open windows next to the units'
sides or back.Avoid wall type fans which create air cross-currents within a room.
It is also necessary that sufficient air should be allowed to enter the room to compensate for the amount of air
removed by any ventilating system. Otherwise, a subnormal atmospheric pressure will occur, affecting
operation and causing undesirable working conditions.
A properly designed and installed hood will act as the heart of the ventilating system for the room or area in
which the unit is installed, and will leave the unit independent of changing draft conditions.
All valves must be checked and lubricated periodically. This must be done by an authorized service
representative in your area.
5. MAINTENANCE
CAUTION: Use only non-abrasive cleaners. Abrasive cleaners could scratch the finish of
your unit, marring it’s appearance and making it susceptible to dirt accumulation. Do Not
use steel wool, other abrasive cleaners or cleaners/sanitizers containing chlorine, iodine,
ammonia or bromine chemicals as these will deteriorate the stainless steel and glass
material and shorten the life of the unit.
Daily:
Weekly:
1. Thoroughly clean back, sides, top and front of unit.
2. Clean grates daily.
1. Clean unit thoroughly. Clean stainless steel or chromed surfaces with a damp cloth and polish with a
soft, dry cloth. A detergent may be used for cleaning. To remove discolorations, use a non-abrasive
cleaner.
2. To clean the drip pan: Remove the drip pan by grabbing the handle and pulling it out of the opening
in the front panel. To replace the pan, reverse this procedure.
3. Burner air shutter openings must be kept clean.
4. Main burner ports must be kept clean. To clean burners, boil them in a strong solution of lye water
for 15 to 20 minutes. Then either brush with a wire brush or clean gas ports with a sharp-pointed
metal instrument to insure open ports.
CAUTION: Clean the regulator at least once a month. Make sure the vent opening is open
and not blocked in any way. Failure to do so will cause variations in pressure. Your unit will
not function as well and it could shorten the life of the product.

Connect the regulator to the unit, connect gas and check for leaks. Do not use an open
flame to check for leaks.
Check the system pressure. With the front panel removed remove the plug
from the manifold.
Place a fitting in the plug opening and connect a manometer.
For Natural gas the pressure in the manifold should be 5”water column or 12.4
millibar. For LP the pressure in the manifold should be 10”water Column or 24.9
millibar.
To adjust the pressure remove the brass cap and turn the white plastic part inside
the stem of the regulator. See picture regulator 8.
Take a wide straight screw driver and place it in the two notches shown in picture regulator 7 turn
clockwise to increase pressure and counter-clockwise to reduce pressure. See picture regulator 8.
Once the pressure has been adjusted replace the brass cap.
Note the blue cap on the regulator, this is the vent there are openings below the top rim. block
these openings your regulator will fail to operate correctly. On at least a monthly basis blow off any dust
or grease which may accumulate around this cap. The openings must remain open for the regulator to
function. Clean more often in a very greasy atmosphere.

6. CONVERSION
l
l
l
Instructions are for conversion from Natural Gas to Propane (L.P.) on all models HHP and HHPS.
The conversion should be done before connecting the unit to the gas supply.
Units are shipped from the factory equipped for use on natural gas. Orifices necessary for LP (propane)
are provided in a bag tied to the valve on the front panel.
1. Remove the knobs and front panel.
2. Remove the orifice fittings from the valve. Change the orifices to the size recommended for
propane (L.P.).
3. Replace the orifice fittings into the valve.
lTo change the regulator:
1. Remove brass
cap
2. Locate the plastic
part attached to the
brass cap
3. This is the natural
gas position
4. Snap the plastic
part off of the brass
cap
5. Flip the plastic part
over & snap the
plastic part onto the
brass cap in the
opposite direction
6. Note you can read
