INSTALLATIONS
Before Installation
- Installation of this device should be operated by professional technicians.
- This device is suitable for a location with an altitude that is lower than 2,000 ft. If it is higher than this altitude, please contact the manufacturer\
- Installation of this unit should conform to provisions of gas safety, installation and usage.
- This device should be kept a minimum clearance of 4” away from non-combustible objects on both sides and 8” at the back (i.e. walls, windows etc.). Do not install on a flammable floor or around other combustible objects.
- This item is intended to be installed on a solid and level floor.
To Install
- Level the device with a level. The height can be adjusted with the adjustable legs.
- The mounting position should be a well-ventilated area with a proper hood exhaust system that will ensure that all of the burned gas produced during use are completely disposed of.
- After installation, level the device and keep stable. Do not sway or tilt during operation.
- Before installation, a quick-acting gas shut-off valve should be installed upstream of the device where it is can be easily reached.
- 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.
- This unit is intended for use with low pressure regulating valves only. High pressure regulating valves and medium pressure regulating valves are not to be used.
- Check to make sure the connection pipe to the unit has no leaks.
- If the connecting pipe pressure is 10% higher or lower than the rated pressure, please install a pressure regulator.
- After connecting the appliance to the gas system, check for leaks at joints and pipe fittings by using soapy water or a specific leak detector (spray). “No Flaming Test!”
- Check the gas supply pressure after installation.
- Gas supply pressure can be measured with a liquid-filled pressure gauge (i.e. 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 the range for the first time please be advised that it might take a little longer to ignite due to air existing in the pipe. If the ignition does not light, turn off the ignition switch and wait 3 minutes to try again.
Controls
Burner
- 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).
- 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.
- When finished, turn off the main burner by rotating the knob clockwise to the off position.
Oven
- Before using the oven, please clean the unit completely, especially the oven chamber. Remove all the packing materials and film from shipping. Before cleaning the stainless steel accessories, make sure that the detergent contains no corrosive substance and is okay for stainless steel surface cleaning. Dry with a clean cloth.
- When first using, an unpleasant smell is normal. (Make sure that the smell is not caused by gas leakage.) An odor is caused by 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℉ and heat unil the odor is gone.
- Upon first use, the duration of ignition may be a little longer due to air existing in the new pipe. It cannot be ignited until all the air is exhausted.
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 lighter via the ignition hole. - 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 release the knob, repeat this operation.
- Keep rotating the temperature control knob counter clockwise to ignite the main burner of the oven. Select the appropriate temperature as required. The oven temperature can be controlled between 250℉and 550℉.
- To turn off the burner: Rotate the knob clockwise to the off position.
Note: If the gas type needs to be changed from NG to LPG, the nozzles of the main burner and pilot flame should 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) / 47# (griddle)/53# (griddle/salamander)
- Liquid Propane Gas Orifice is 52# (top)/50# (oven) /54# (griddle)/57# (griddle/salamander)
- Orifice size is marked on the spud
CLEANING & MAINTENANCE
It is important to check the machine daily. Checking the machine regularly can prevent serious accidents. Stop using the range if you suspect there are some problems with the unit. Check the condition of the machine before and after using every day.
Before using:
Is the machine tilted?
Is the control panel damaged?
During use:
Is there a strange smell or vibration noise?
Is the flame color of the burners normal? Any light back or flame out?
- Before cleaning, turn off all gas valves.
- Clean the burners and tray for odds and ends regularly.
- 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 (i.e. KCL).
- Clean the dirt on the burners and baffle regularly.
- Do not modify the ventilation volume needed during combustion.
- Accumulation of the iron substance (e.g. Material that is formed by iron rust dissolving in water in the pipe, especially when the unit is out of use for a long time). To avoid accumulation of such substance, clean the food residue that is difficult to clean with a stainless steel scraper or brush containing no iron substance instead of a steel brush.
- Prevent substances such as acidic ingredients, i.e. vinegar, lemon juice, spices, salt etc. from long term contact with the stainless steel accessories. Vapor of acid solution will damage the surface of the device seriously.
- A complete cleaning every day will ensure good service and extend the life of the unit. Clean the unit with a wet towel containing suds or a detergent, rinse it with water and dry it with a clean cloth. Do not clean the device with a steel brush, which may cause rust. Similarly, do not contact the unit with substance containing iron.
- Splotch and abrasion of the stainless steel surface: Scratches and black stains can be cleared away with an artificial sponge. During cleaning, the direction should be the same as polishing.
- Rusting: To remove rust, contact an industrial detergent manufacturer to find a proper detergent to remove such rusting. Industrial rust removal products may be used. After cleaning, rinse it with clear water. If necessary, neutralize the residual acid chemical compound with alkaline detergent.
- To avoid rusting of the unit, please make sure that the residual salt inside or outside the device is cleared away.
- After cleaning, to avoid incomplete combustion, the fire hole of the burner should be cleared.
- If the unit is not going to be used for a period of time, please turn off the gas valve upstream to the device or the main gas line.
- If the unit is not going to be used for a long time, please clean the stainless steel surface with a gasoline cloth and store it in a well-ventilated area without corrosive gas.
- 90% of the device is metals (stainless steel, iron, aluminum, galvanized metal sheet) which can be recycled by appointed treatment plant according to environmental standards of the equipment installation municipalities. Please recycle.
