located inside the kick panel of the unit. If the supply and equipment requirements do not agree,
do not proceed with the installation. Contact your dealer immediately.
• Unit must be installed so that the ow of combustion and ventilation air will not be obstructed,
ensure that there is an adequate supply of air in the room to allow proper combustion of gas at
the burners.
• This device should be kept a minimum clearance of 12" from combustible construction at the
sides and 10" at the rear. Clearance from non-combustible construction is 0" sides and 6" at the
back. Do not install on a ammable oor or around other combustible objects.
• This item is intended to sit on a solid and level oor.

BEFORE INSTALLATION
INSTALLATION
Clearance and positioning:
• This equipment must be installed adjacent to non-combustible surfaces only with a minimum
spacing of 6" from all sides. This equipment must be a distance of 6" from other equipment. The
equipment must have the 4" legs installed and be placed on a non-combustible surface.
• For an oven equipped with casters, the installation shall be made with a connector that complies
with the Standard for Connectors for Movable Gas Appliances, ANSI Z21.69/CSA 6.16 and a
quick-disconnect device that complies with the Standard for Quick-Disconnect Devices for Use
with Gas Fuel, ANSI Z21.4/CSA 6.9. When installing the oven with casters and quick-disconnect
hose, adequate means must be provided to limit the movement of the oven without depending
on the connector and the quick disconnect device or its associated piping to limit the oven
movement. Restraining means may be attached to the vertical portion of the base frame in the
rear of the oven.
1. Level the device with a level gauge. The height can be adjusted by the adjustable feet. Unit should
not sway or tilt during operation. Units that are not level will experience operational problems.
2. The mounting position should be well-ventilated with proper hood exhaust system.
3. Codes require that a gas shut off valve should be installed upstream the device where it is easily
reached during operation.
4. Make sure you are using the correct gas supply that is specied for this model. If the gas supply is
not intended for this model, do not proceed with installation.
5. This unit is applicable to low pressure regulating valves only. High pressure regulating valves and
medium pressure regulating valves are not to be used.
6. Check to make sure the connection pipe to the unit has no leaks and that all connections and pipe
joint compound used are resistant to the action of propane gases.
Air Supply and ventilation:
• The area in front and around the equipment must be kept clear to avoid any obstruction of the
ow of combustion and ventilation air.
• Adequate clearance must be maintained at all times in front of and at the sides of the equipment
for servicing and proper ventilation.

INSTALLATION
7. A pressure regulator must be installed with this unit. Ensure that the regulator type is in agreement
with the rating plate gas supply. Regulator must be upright after installation. If regulator is not level
during operation, performance problems may result.
8. After connecting the appliance to the gas system, check for leaks at joints and pipe ttings; to do
so, use soapy water or a specic leak detector (spray).
9. Check the gas supply pressure after installation.
10. Gas supply pressure can be measured with a liquid-lled pressure gauge (e.g. a U-shaped
pressure gauge, minimum scale division 0.1mbar) or a digital gauge. Procedure as follows:
• Ensure gas is turned off
• Remove the panel and unscrew the screw on the pressure port
• Place the pressure gauge
• Start up the appliance by following the instructions in this owner’s manual
• Check supply pressure. Pressure must agree with rating plate requirement when the unit is in
full operation
• After the check, turn off gas and remove the pressure gauge
• Replace the sealing screw
OPERATION
When turning on for the rst time please be advised that it might take a little longer to ignite due to
the air existing in the pipe.
BURNERS:
• Turn on the gas supply and ignite the pilot ame with a lighter. If the unit hasn’t been used in a
while or if this is the rst lighting, ignition might take a little longer (about two or three minutes).
• Press the corresponding valve knob of burner and turn 90 degrees counterclockwise.
The burner will be ignited and the ame will be at Max. To set the ame to Min, rotate
counterclockwise another 90 degrees.
• When nished turnoff main burner by rotating the knob clockwise to off position. Pilot should
remain lit.
• For complete shutdown, ensure that all burner knobs are turned to the off position, and then
turn main gas supply off.

GAS CONVERSION
CLEANING
Conversion from Natural Gas to Liquid Propane (LP) or vice versa may only be performed by the
factory or its authorized service agent.
NOTE: It is important to check the machine daily. Checking the machine regularly can avoid serious
accidents. Stop using if user feels that there are some problems with the unit. Check the condition of
the machine before and after using every day.
1. Before cleaning, turn off all gas valves.
2. Please clean the burners and drip tray of all debris and spillage daily. A complete cleaning every
day will ensure a good service and extend the service life of the unit.
3. Clean the stainless steel surface with warm soapy water every day and rinse it completely. Do not
saturate range with water, excessive water will cause operational issues. During cleaning, do not
clean the stainless steel surface with abrasive detergent, brush or scraper etc. The residual iron
scale may cause rusting.
4. Do not clean the surface with chlorine cleanser (bleach, dish detergent, hydrochloric acid etc.).
Do not clean the oor where the device locates with corrosive substance.
5. Do not change the burner shutter settings.
6. Accumulation of substances containing salt or acidic ingredients, e.g. vinegar, lemon juice,
spices, salt etc. can cause corrosion. Thus, please do not allow these substances to have long
contact with the unit.
7. After cleaning, ensure that the ports of the burners are open and clear of any residue.
8. Clean cast iron top grates with a mild soap and water solution. Rinse thoroughly and dry with a
clean, water-absorbent towel. Immediately after drying, season grates lightly with liquid vegetable
oil. After seasoning, replace grates on range and turn burners on LOW, allow grates to heat for 15
minutes before using pots or pans on the range top. Failure to season grates after cleaning will
result in rust.
9. If unit will sit idle for a signicant period of time, please turn off the gas valve upstream the device.
