Gas Piping: Gas piping shall be of such size and so installed as to provide a supply of gas sufficient
to meet the full gas input of the appliance. If the
appliance is to be connected to existing piping, it
should be checked to determine if it has adequate
capacity. Joint compound (pipe dope) should be
used sparingly and only on the male threads of the
pipe joints. Such compounds must be resistant to the
action of Liquefied Propane (LP) gases.
Regulator information: ¾” NPT (National Pipe
Thread) inlet and outlet; factory adjusted for ten
(10”) inch Water Column (WC) LP Gas standard and may be converted by qualified personnel tobe
used for Natural at five (5”) Water Column pressure.
Prior to connecting the regulator, check the incoming line pressure. The regulator can only withstand
a maximum pressure of½ PSI (14” WC). Ifthe line pressure is beyond this limit, a step down
regulator before the regulator provided will be required. The arrow forged into the bottom ofthe
regulator body shows gas flow direction, and should point downstream to the appliance.
CAUTION: Any loose dirt or metal particles, which are allowed to enter the gas lines on this
appliance, will damage the valve and affect its operation. When installing this appliance, all pipe and
fittings must be free from any internal contaminates. Itisrecommended that a “drip leg” be installed
in-line before the regulator. See diagram above.
Manual Shut Off Valve: Amanual shut off valve should be installed upstream from the manifold,
within four (4) feet, (1.2M) ofthe appliance and in a position where it can be reached in the event of
an emergency.
Checking For Gas Leaks: Using a gas leak detector or a soapy water solution is recommended for
locating gas leaks. Matches, candle flame, or other sources ofignition shall not be used for this
purpose. Check entire piping system for leaks.
DO NOT use an open flame to check for leaks. Check all gas piping for leaks with a soap and water
solution before operating the unit.

OPERATION
Control Panel:
Burner Knobs Crumb Tray Pilot Adjustment Valves
Top Burners:
1. Connect the gas supply and ignite the pilot flame with a lighter. If the device is stopped using
for a long time or first used, 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 burner counter clockwise, the burner will be ignited. 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.
Operating the Griddle – Pilot Lighting Instructions for MANUALLY CONTROLLED GRIDDLES
Before operating Griddle, it should be checked to see that is sitting level. Adjust the feet to level the Griddle. 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.
As continued product improvement is a policy of Vionet, specifications are subject to change.

Range Owner’s Manual Rev 20190121
If the pilot flame appears large 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 in 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 Thermostat controlled griddle, turn the knob to the desired temperature
and allow it to preheat for approximately fifteen (15) minutes. (*Be sure the griddle plate has been properly season before
attempting to cook). The space between the legs at the bottom admits combustion air. DO NOT BLOCK THIS SPACE.
All burners are lit from a constantly burning pilots. Turning the valve to the desired flame height is all that is required to put
the unit in service. Or if thermostatically controlled, simply set to the desired temperature.
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 or the lowest setting on the dial if it is a thermostatically controlled
griddle, 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,
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.
As continued product improvement is a policy of Vionet, specifications are subject to change.

Range Owner’s Manual Rev 20190121
OPERATING THE GRIDDLE
Turn the burners on about 15-20 minutes before cooking for preheating. Set the knobs to the desired flame height.
NOTE: On 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:
1. Before using, please clean the oven and range completely. Remove all the packing materials and film. Before
cleaning the stainless steel accessories, please make sure that the used detergent contains no corrosive
substance and suits to the stainless steel surface cleaning. Then dry the range with clean cloth.
2. 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.
3. Burn Off Period. When first using, it is normal there is unpleasant odor and smoke. (Make sure that the smell
is not caused by gas leakage.) In fact, that 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.
4. During ignition, please open the kick plate below the door downward, press down the knob and
rotate it counter clockwise to , and press down. Ignite the pilot flame with lighter via the ignition
hole.
5. 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.
6. By-Pass Setting: 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.
7. Keep rotating the temperature control knob counter clockwise to ignite the main burner of the oven. Select
appropriate temperature according to food requirement. The oven temperature can be controlled between
200°F and 600°F.
Note: If the gas type needs to be changed from LPG to NG,the nozzles of main burner and pilot flame should be
replaced.
