Each burner has a pilot light.

8.1、Before first use

Remove all packing material and protective plastic from surfaces of the unit. Before leaving the factory, the griddle plate is coated with protective coating as a rust inhibitor. Heat the griddle to 200-300°F to loosen and melt the coating, then clean the surface with a non-corrosive. Rinse thoroughly and wipe dry with a soft clean cloth. Clean all accessories. Do not use corrosive or abrasives detergent. Tip : Season the griddle to avoid possible surface corrosion before first use, and after every cleaning. Heat griddle to a low temperature(300-350 °F) and apply a small amount of cooking oil-about one ounce per square foot of surface. Use a soft lint-free cloth to spread the oil over the entire griddle surface to create a thin film. Wipe off any excess oil with a cloth. Repeat the procedure until the griddle has a slick, mirror-like finish. This will also help reduce the sticking of cooked food product. Notice: Before first preheating, the furnace will smoke rise. This is because of protective lipids on the grills and other parts are heated, it is normal, and it will be eliminated after the power up to the maximum for burning an hour.

8.2、Lighting the pilot light and Igniting the main burner

1. Align the OFF indicative line of thermostat valve knob to the arrow (Figure 2) to close the valve. 2. And then axial press the thermostat valve knob, left 45 degrees, to the pilot position. (Figure 3) 3. At the fire position, completely press the knob, meanwhile light the fire by pilot with another hand. (Figure 4) Keep pressing the knob about 10-15 seconds, then loosen the knob and observe stability of fire. 4. If the pilot fire is not ignited, please repeat the procedure above until the pilot fire is ignited. 5. After successful ignition, the main fire valve was opened, turn left to the desired temperature (figure 5) and the griddle starts warming. When reaching the set temperature, the thermostat valve will automatically adjust the gas flow to keep the temperature on the griddle constant. Tips :The pilot light may not be lighted immediately, for existing gas in the pipe. Wait a minute, the pilot light will be lighted after the gas extinguished.  Fig.2  Fig.3

Fig.5 ⚠️ Make sure air circulation well at the bottom of equipment; Do not use fan or air-conditioning blowing at the flame, in order to avoid extinguishing flame and cause safety accidents; ⚠️ Install the matched cooking fume exhauster according to the local regulations of char broiler; ⚠️ Make sure to keep the natural air circulation in the kitchen.

8.3、Turn off the valve

Revolve the control valve knob to the pilot position (Fig.3). the main fire burner flame is extinguished, but the pilot light will continue to work. Axial press the knob to rotate knob clockwise continually, so that the direction of the knob on the "off" position, at this time, the fire extinguished, the valve closed (Fig.2). After turning off the equipment, the main fire should be stop more than 5 minutes before next using.

8.4、Exchange the main fire nozzle and the pilot orifice to switch gas source

Remove control panel, grill, take off the pilot assemblies and main fire nozzle with a wrench, exchange the other gas of the main fire nozzle (Fig.6) and the pilot orifice (Fig.7), then screw it. Reinstall the grill, the pilot assemblies and the control panel in proper place. Caution: Each main fire nozzle of the burner has been installed before delivery, normal use without adjustment but only switching gas. Adjust only by authorized and licensed technicians. When you change the gas source, you need exchange the corresponding pressure maintaining valve which installed on air intake.  Fig.6  Fig.7
