OPERATION
Control Panel: (Top Section View)
Burner Knobs Oven Thermostat Crumb Tray Pilot Adjustment Valves
Top Burners:
1. Connect the gas supply and ignite the pilot flame with a lighter. During the first use or when
device has not been used in a long time, it is normal that the duration of ignition may be a little
longer (about two or three minutes).
2. Turn the corresponding valve knob of the burner counterclockwise; the burner will ignite. If the
knob is aligned with the round dot on the panel, the flame is Max. To set the flame to Min, rotate
counterclockwise to the Min flame position.
3. After using, turn off the main burner. To shut down, rotate the knob clockwise to origin position.
4. If not using the device, please turn off all the burner valves.
Off Position Low Position High Position
Operating the Griddle –Pilot Lighting Instructions for MANUALLY CONTROLLED GRIDDLES
Before operating Griddle, make sure it is level. Adjust the feet to level the Range. Be sure the catch tray had been
properly placed.
Manual Griddle Knob
The pilot light on the appliance has been set at the factory. Each burner has a pilot light.
1. Make sure all knobs are in the “OFF” position.
2. The main gas valve should be “CLOSED/OFF” for five (5) minutes prior to lighting plots to
clear any existing gas. (Main gas valve is supplied by others.)
3. Turn “ON or OPEN” the main gas valve to the unit.
4. Light and hold an ignition source (match) at the pilots. When the flame is established, remove the ignition source.
Repeat this step for each burner as each burner has its own individual pilot. The pilot can be reached through the
holes in the front of the unit.
5. Turn each burner knob “ON”. If the burners do not ignite promptly, turn the knobs “OFF”. From the opening in the
front panel, use a screwdriver and turn the pilot valve screw counterclockwise, which will increase the flame
height and repeat step 4.

8
For Warranty Service Call: 866-359-7378 Range Owner’s Manual Rev IR20200228
If the pilot flame appears larger than necessary, turn it down and retest the 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 “ON”. In the holes located in the front panel are pilot valve adjustments. Use a screwdriver to turn the valve to
adjust the flame height to your desired level.
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 into service.
Igniting the Burner
To ignite the burner, turn knob to the “ON” position, then back off to the desired flame level. The range of adjustment is
virtually infinite between “ON” and “OFF”. On the griddle, turn the knob to the desired setting and allow it to preheat for
approximately fifteen (15) minutes. (*Be sure the griddle plate has been properly seasoned before attempting to cook).
Do not permit fans to blow directly at the unit. Whenever possible, avoid open windows next to the unit’s 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 ventilation 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 ventilation system for the room or area in which the unit
is installed and will leave the unit independent of changing draft conditions.
NOTE: It may be necessary to adjust the balance of gas, volume, and air supply to each burner. This must be done by an
authorized service technician.
SEASONING THE GRIDDLE
Be sure to start with a clean Griddle surface. Pour small amount of high quality cooking oil to the griddle plate (about one
ounce (30 cc) per square foot of surface. Spread the oil over the entire griddle surface with a clean cloth to create a thin
film. Turn on the griddle to the lowest flame height and allow to heat for approximately 30 minutes. As the griddle is
heating it will be necessary to spread the oil over the griddle surface to prevent it from drying. Repeat this process 2 to 3
times gradually increasing the flame height each time on the burner until the griddle has a slick, mirror-like surface. This
process will take 1 ½ to 2 hours.
Note: Each time the griddle is cleaned with SOAP and WATER, the seasoning is removed, and this process must be
repeated.
Note: If the process occurs too fast the griddle surface may turn a light bluish tint in color. The tint does not hurt the
griddle surface. You should allow the surface to cool and start over.
OPERATING THE GRIDDLE
Turn the burners on about 15-20 minutes before cooking for preheating. Set the knobs to the desired flame height.
NOTE: This is a Manually Operated Griddles there is NO TEMPERATURE CONTROL, you the operator, must maintain
temperature by increasing or decreasing the flame height as required.
Each valve controls the gas flow to the burner to bring that area of the griddle up to the desired temperature. If different
temperature settings are to be used, adjoining areas should be set to progressively higher temperatures using the lowest
temperature on the outside burners. A uniform and systematic approach to the loading of the unit will produce the most
consistent product results.
OPERATING THE OVEN:

9
For Warranty Service Call: 866-359-7378 Range Owner’s Manual Rev IR20200228
Before using, please clean the oven and range completely. Remove all the packing materials and film. Before cleaning the
stainless steel accessories, make sure the detergent is suitable for stainless steel surface cleaning and contains no
corrosive substances. Then dry the range with clean cloth.
1. For first use, the duration of ignition may be a little longer due to the air existing in the new pipe. It cannot be
ignited until all the air is exhausted.
2. Burn Off Period. Upon the first use, there may be an unpleasant odor and/or smoke. This is normal. (Make
sure that the smell is not caused by gas leakage.) In fact, this is produced by overheating of the insulating
material and oil residue during the manufacturing process. Set the temperature to 450°F and allow to heat
until the smell is gone, and oven stops smoking. Then use as normal.
3. To ignite of the oven pilot, open the kick panel below the oven door by lifting up then swing
downward, locate the pilot access hole. Press down the knob and rotate it counterclockwise to ,
and press down. Ignite the pilot flame with lighter via the ignition hole.
4. After the pilot flame is ignited, press the knob for more than 20 seconds to heat up the
thermocouple. If the ignition is out when you loosen the knob, repeat this operation.
5. Oven Thermostat By-Pass Setting, (This should be done by a qualified technician upon installation): With the
oven cold or at room temperature turn the dial to 300°F and observe the burner flame. Allow to heat for
approximately 5 minutes, turn the dial to the lowest setting and observe the burner blame. There should now
be a small, but stable flame on the burner, approximately 1/8” high.
If not, turn the by-pass screw located on the oven thermostat at the six
o’clock position, to obtain the lowest, stable flame on the burner. NOTE: If
not done correctly poor oven performance will occur.
6. Keep rotating the temperature control knob counterclockwise to ignite the
main burner of the oven. Select appropriate temperature according to food requirement. The oven
temperature can be controlled between 250°F and 550°F.
Note: If the gas type needs to be changed from NG to LPG, the nozzles of main burner and pilot flame should be
replaced, and the oven thermostat by-pass setting will need to be adjusted for the different fuel type.
Routine Inspection
It is necessary to inspect the range daily. Checking the range regularly can avoid any serious
accidents and expensive damage. Stop using if user feels that there are some problems in normal
operation of the range. Check the condition of the range before or after each use.
Before using: Is the range tilted? Is the control panel damaged?
During using: Is there a strange smell or vibration noise? Is the burner flame normal? Any flash back
in burner or lifting flames? If so, please contact service immediately.
