Griddle seasoning (Models 29Y-046, 29Y-047)
Caution: This griddle plate is steel, but the surface is relatively soft and can be scored or dented by the careless use of a spatula or scraper. Be careful not to dent, scratch, or gouge the plate surface. Do not try to knock off loose food that may be on the spatula by tapping the corner edge of the spatula on the griddle surface.
A new griddle surface must be seasoned before use. The metal surface of the griddle is porous. Food tends to get trapped in these pores and stick; therefore, it is important to season or fill up these pores with cooking oil before cooking. Seasoning gives the surface a slick, hard finish from which the food will release easily.
To season, heat griddle top section at low burner setting. Pour one ounce of cooking oil per square foot of surface over the griddle top section. With an insulated cloth, spread the oil over the entire griddle surface to create a thin film. Wipe off any excess oil with an insulated cloth. Be careful to not touch the griddle during this process. Using a spatula or grill scraper with an insulated cloth on the end is good practice.

Repeat this procedure 2 to 3 times until the griddle has a slick surface.

Working Instructions & Operation

Control Panel:

Gas Range：

1. Turn on the gas valve and light up the pilot flame (kindling) with an ignitor. If the appliance is idle for a long period of time or used for the first time, duration of ignition may be a little longer than usual (appropriately 2-3 min), which is normal.
2. Press the valve knob for corresponding burner axially and turn it counterclockwise for 90°to light up the burner. To turn the flame to MAX, rotate the knob to align “ ” on knob with the round dot on panel; to turn it to MIN, rotate the knob counterclockwise to “ ”.
3. After working, turn off the main burner: rotate the knob clockwise to the round dot position.
4. If the Range is not in use, turn off the quick acting disconnecting valve.

Hot Top and Griddle 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 used for the first time, it is normal that the duration of ignition may be a little longer (about two or three minutes).
   Use a long stick lighter to ignite the Griddle pilot through the pilot holes, see below Figure. DO NOT leave the gas on for an extended period before lighting. Light the pilot with 30 seconds of turning on the gas.

2. Press the corresponding valve knob of burner axially; 90 degrees anticlockwise, the burner will be ignited. If “ ” on the knob is aligned with the round dot on the panel, the flame is Max. To set the flame to Min, rotate anticlockwise to the Min flame position. “ ” is Min.

3. After using, turn off the main burner. To shut down, rotate the knob clockwise to origin position.

4. If the Range is not in use, turn off the quick-acting switching-off valve.

Oven (Standard):

1. Before using, please clean the Equipment completely, especially the oven chamber. Remove all the packing materials and film. Before cleaning the stainless steel accessories, make sure that the used detergent contains no corrosive substance and suits to the stainless steel surface cleaning. Then dry the device with clean cloth.
2. When first using, it is normal that there is unpleasant smell. (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 heating process of the metal. If the oven is used at the first time, do not put any food into the chamber, set the temperature to 550F 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. Responding temperature of the chamber center on the oven knob: 250-550 F
5. During ignition, please open the lid under the door downward, press down the knob and rotate it anticlockwise to “ ”, align with the salient point and press down. Ignite the pilot flame with lighter via the ignition hole.
6. 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.
7. 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 250F and 550F.
8. To turn off the burner: Rotate the knob clockwise to strip mark and align with the salient point.

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

Routine Inspection
It is necessary to check the machine daily.
Check the machine regularly can avoid serious accidents and prolong the life of the Range.
Stop using if there is noticeable damage or a malfunction with the Range.
Check the below statuses of the Range before or after using every day.

• Before using:
  • Whether the machine is level?
  • Whether the control panel is damaged?
  • Make sure the grease tray is clean and empty.
• During using:
  • Whether there is strange smell or vibration noise?
  • Whether the flame of burner is normal? Any light back or flameout?
  • Whether the power is normal?
  • Dump the grease in the grease tray regularly to avoid the grease spill out

Cleaning & Maintenance

1. Before cleaning, please turn off the Range and the gas valve upstream it.
2. Clean the burners and tray regularly to prevent excess build-up.
3. Clean the stainless steel surface with warm soap every day and rinse it completely.(Do not spray the Range with a hose directly.)
4. During cleaning, do not clean the stainless steel surface with abrasive detergent, brush or scraper etc. The residual iron scale may cause rusting. Scrub it according to direction of satin. Do not clean the surface with chlorine cleanser (bleach, hydrochloric acid etc.) even though these products are dilute.
5. Do not clean the floor where the device locates with corrosive substance.
6. Do not clean motor and electronic devices with any conductive substance.
7. Clean the grease/dirt on the burners and baffle regularly.
8. Do not modify the ventilation volume needed during combustion.
9. Accumulation of the iron substance (e.g. Material that formed by iron rust dissolving in water in the pipe, especially when the Range is not used for a long time.). Therefore, to avoid accumulation of such substance, clean the food swill that is difficult to clean with stainless steel scraper or brush containing no iron substance instead of steel brush.
10. Accumulation of substance containing acidic ingredient, e.g. vinegar, lemon juice, spices, salt etc. Thus, please keep these substances away from long contacting with the stainless steel accessories. Vapor of acid solution will damage the surface of the device seriously.
11. 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 detergent, rinse it with clear water and dry it with clean cloth. Empty the drip pan on time to avoid overflow from fire risks, especially for griddle products. Do not clean the Range with steel brush, which may cause rust. Similarly, do not contact the Range with substances containing iron.
12. To avoid rusting of the equipment, please make sure that the residual salt inside or outside the Range and oven is cleared away.
13. After cleaning, to avoid short-time incomplete combustion, the fire hole of the burner should be clean and unblock.
14. If not going to use the Range at any time, please turn off the gas valve upstream the device or the power main switch.
15. If not going to use the Range for a long time, clean the stainless steel surface with a soft cloth and store it in a well-ventilated warehouse without corrosive gas.
