20. Griddle seasoning
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 to do a good cooking job . The metal surface of
the griddle is porous .Food tends to get trapped in these pores ans stick ;therefore ,it is
important to seasoned 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 .
Repeat this procedure 2 to 3 times until the griddle has a slick surface.

5.1 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 first used, it is normal that the duration of ignition may
be a little longer (about two or three minutes).
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 not going to use the device, please turn off the quick-acting switching-off valve.

11
5.2 Oven:
1. Before using, please clean the device completely, especially the oven chamber.
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 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
320℃and heat till 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: 100℃, 150℃,
200℃, 250℃, 320℃
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 anticlockwise to ignite the main burner of
the oven. Select appropriate temperature according to food requirement. The oven
temperature can be controlled between 100℃and 320℃.
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.
6. Routine Inspection
It is necessary to check the machine daily.
Check the machine regularly can avoid serious accident happens.
Stop using if user feels that there are some problems in the circuit or machine.
Check the situation of the machine before or after using every day.
Before using: Whether the machine is tilted?
Whether the control panel is damaged?
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?

7. Cleaning & Maintenance
1. Before cleaning, please turn off the device and the gas valve upstream it.
2. Please clean the burners and tray for odds and ends regularly.
3. Clean the stainless steel surface with warm soap-suds every day and rinse it
completely. (Do not spray the device with water cannon 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 (e.g. KCL).
6. Clean the dirt on the burners and baffle regularly.
7. Do not modify the ventilation volume needed during combustion.
8. Accumulation of the iron substance (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.).
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.
9. 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.
10. A complete cleaning every day will ensure a good service and extend the service life
of the device. Clean the device with a wet towel containing suds or detergent, rinse it
with clear water and dry it with clean cloth. Do not clean the device with steel brush,
which may cause rust. Similarly, do not contact the device with substance containing
iron.
11. Splotch and abrasion of the stainless steel surface: Scrape and black stain can be
cleared away by artificial sponge. During cleaning, the direction should be the same
as the polishing.
12. Rusting: To remove the rusting, please contact the industrial detergent manufacturer
to find a proper detergent to remove such rusting. Industrial rust removal products
may do. After cleaning, rinse it with clear water. If necessary, neutralize the residual
acid chemical compound with alkaline detergent.
13. To avoid rusting of the device, please make sure that the residual salt inside or
outside the device is cleared away.
14. After cleaning, to avoid short-time incomplete combustion, the fire hole of the burner
should be clean and unblock.
15. If not going to use the device at any time, please turn off the gas valve upstream the
device or the power main switch.
16. If not going to use the device for a long time, please clean the stainless steel surface
with gasoline cloth and store it in a well-ventilated warehouse without corrosive gas.
17. 90% of the device is metals (stainless steel, iron, aluminum, galvanized metal sheet)
which can be recycled by appointed treatment plant according to environmental

13
standards of the equipment installation countries. (No littering!)
