Installation

Before Installation

1. The installation of this range should be performed by professional technicians.
2. This range is suitable for areas whose altitude is lower than 2000 ft. If it is higher than this altitude, please contact the manufacturer.
3. The installation of this unit should conform to the provisions of gas safety, installation and usage.
4. This range should be kept at a minimum clearance of 4 inches away from non-combustible objects on both sides and 8 inches at the back (e.g., walls, windows etc.). Do not install it on a flammable floor or around other combustible objects.
5. This range is intended to sit on a solid and level floor.

To Install

1. Level the device with a level gauge. The height can be adjusted by the adjustable legs.
2. The mounting position should be well-ventilated with a proper hood exhaust system that will ensure that all the burnt gas produced during use is completely disposed of.
3. After installation, level the device and keep it stable. Do not sway or tilt during operation.
4. A quick-acting switching-off gas valve should be installed upstream from the range where it is easy to reach before installation.
5. Make sure you are using the correct gas supply that is specified for this model. If the gas supply is not intended for this model, do not proceed with installation.
6. This unit is applicable to low pressure regulating valves only. High pressure regulating valves and medium pressure regulating valves are not to be used.
7. Check to make sure the connection pipe to the unit has no leaks.
8. If the connecting pipe pressure is 10% higher or lower than the rated pressure, please install a pressure regulator.
9. After connecting the appliance to the gas system, check for leaks at joints and pipe fittings; to do so, use soapy water or a specific leak detector (spray). "No Flaming Test!"
10. Check the gas supply pressure after installation.
11. Gas supply pressure can be measured with a liquid-filled pressure gauge (e.g., a U-shaped pressure gauge, minimum scale division 0.1mbar) or a digital gauge. Procedure as follows: 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, after the check, remove the pressure gauge, replace the sealing screw.

Operating Instructions and Controls

When turning on for the first time, please be advised that it might take a little longer to ignite due to the air existing in the pipe. If the ignition does not light, turn off the ignition switch and wait 3 minutes to try again.

Burner Operation

1. Connect the gas supply and ignite the pilot flame with a lighter. If the unit hasn't been used in a while or if this is the first lighting, ignition might take a little longer (about two or three minutes).
2. Press the corresponding valve knob of the burner and turn 90 degrees counterclockwise. The burner will be ignited, and the flame is Max. To set the flame to Min, rotate 180 degrees counterclockwise to the Min flame position.
3. When finished, turn off the main burner by rotating the knob clockwise to the off position.

Oven Operation

1. Before using the oven, please clean the unit completely, especially the oven chamber. Remove all packing materials and film from shipping. Before cleaning the stainless steel, ensure the detergent contains no corrosive substance and is suitable for stainless steel surface cleaning. Then dry with a clean cloth.
2. When first using it, it is normal that there is an unpleasant smell (ensure the smell is not caused by gas leakage). The smell is produced by the overheating of the insulating material and oil residue during the heating process of the metal. If the oven is used for the first time, do not put any food into the chamber; set the temperature to 550°F and heat until the smell is gone.
3. When first using, 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.
4. During ignition, please open the lid under the door downward, press down the knob and rotate 61° counterclockwise, align with the salient point and press down. Ignite the pilot flame with a 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 goes out when you loosen the knob, repeat this operation.
6. Keep rotating the temperature control knob counterclockwise to ignite the main burner of the oven. Select the desired temperature according to food requirement. The oven temperature can be controlled between 200°F and 500°F.
7. To turn off the burner: Rotate the knob clockwise to the strip mark and align with the salient point.

Note: If the gas type needs to be changed from NG to LPG, the nozzles of the main burner and pilot flame need to be replaced.

Gas Conversion

Conversion from Natural Gas to Liquid Propane (LP) or vice versa may only be performed by the factory or its authorized service agent. In case of troubleshooting, ensure the correct orifice sizes of the spuds have been provided.

• Natural Gas Orifice is 39# (top) / 33# (oven) N18 (oven pilot).
• Liquid Propane Gas Orifice is 52# (top) / 50# (oven) LP10 (oven pilot).
• Orifice size is marked on the spud.

Cleaning & Maintenance

It is important to check the range daily. Checking the range regularly can avoid serious accidents. Stop using it if you feel that there is a problem with the range. Check the range before and after using every day.

Before using:

• Is the machine tilted? If it is, it needs to be leveled.
• Is the control panel damaged? If it is, it needs repaired.

During using:

• Is there a strange smell or vibration noise? If there is, stop using.
• Is the flame color of the burner normal? Is there any light back or flame out?

Cleaning Steps:

1. Before cleaning, turn off all gas valves.
2. Clean the burners and tray for debris and food particles regularly.
3. Clean the stainless steel surface with warm soapy water every day and rinse it completely. During cleaning, do not clean the stainless steel surface with abrasive detergent, brush or scraper etc. The residual iron scale may cause rusting. Do not clean the surface with chlorine cleanser (bleach, hydrochloric acid etc.). Do not clean the floor where the device is located with corrosive substances.
4. Clean the debris on the baffle regularly.
5. Do not modify the ventilation volume needed during combustion.
6. Accumulation of iron substance may happen (e.g., material that formed by iron rust dissolving in water in the pipe, especially when the device is not used for a long time). To avoid accumulation of this substance, clean the food swill from the range daily.
7. Accumulation of substances containing acidic ingredients may happen (e.g., vinegar, lemon juice, spices, salt etc.). Please keep these substances away from long contact with the stainless steel. Acid solutions will damage the surface of the range.
8. A complete cleaning every day will ensure a good service and extend the service life of the range. Clean the range with a wet towel containing suds or a detergent, rinse it with water and dry it with a clean cloth. Do not clean the range with a steel brush, which may cause rust. Similarly, do not contact the unit with substance containing iron.
9. If there is an abrasion on the stainless steel surface, clean and polish in the direction of the stainless steel.
10. Rust: To remove the rust, use an industrial detergent to remove and then clean the area with mild soap and water. If necessary, neutralize the residual acid chemical compound with alkaline detergent.
11. To avoid rust, make sure that the residual salt inside or outside the range is cleared away.
12. After cleaning, to avoid short-time incomplete combustion, the fire hole of the burner should be clear.
13. If you are not going to use the range for a few days, turn off the gas valve upstream.
14. If not going to use the range for a long time, clean the stainless steel surface and store it in a well-ventilated area without corrosive materials.
15. 90% of the range is metal (stainless steel, iron, aluminum, galvanized metal sheet) which can be recycled.
