If disconnection of the restraint is necessary, turn off the gas supply before disconnecting. Reconnect the restraint prior to turning the gas supply on and returning the griddle to its installation position. Casters are only supplied on a griddle stand. If the griddle is moved for any reason the griddle should be re-leveled (see LEVELING in this manual). FLUE CONNECTIONS Do not obstruct the flow of flue gases from the flue, located at the rear of the griddle. It is recommended that flu

GAS PRESSURE REGULATOR INSTALLATION A gas pressure regulator is supplied with the griddle and must be installed. Install the regulator as close to the griddle on the gas supply line as possible. Make sure that the arrow on the underside of the regulator is oriented in the direction of gas flow to the griddle (Fig. 2) and the regulator is positioned with the vent plug and adjustment screw upright (Fig. 3). Check and set the gas pressure after the regulator is installed. The pressure sh

OPERATION The griddle and its parts are hot. Use care when operating, cleaning or servicing the griddle. BEFORE FIRST USE Remove all packing material and protective plastic from the surfaces of the unit. Before leaving the factory the griddle is coated with vegetable oil as a rust inhibitor. Remove this film when the griddle plate is being cleaned prior to its first cooking use. Heat the griddle to 200-300°F to loosen and melt the coating, then clean the surface by adding water or

This model features an electric ignition system that is controlled by a momentary power switch. The power switch turns the electric ignition system off and on only and will only supply power to the igniters when held down in the ON position. The burners and pilots will continue to work with power switch in the OFF position until the gas supply to the unit is cut off or the griddle gas shut-off valve is turned to the OFF position (Fig. 6). In the event of a failure of the electronic ignitio

USING THE GRIDDLE To preheat, turn the burners on about 20-25 minutes before cooking. A uniform and systematic approach to loading the griddle will produce the most consistent product results. The griddle plate is steel, but the surface is relatively soft and can be scored or dented by 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 or the edge of the

CLEANING THE GRIDDLE Empty the grease drawer as needed throughout the day and regularly clean at least once daily. Clean the griddle regularly. A clean griddle always looks better, lasts longer and performs better. To produce evenly cooked, perfectly browned griddle products keep the griddle plate clean and free of carbonized grease. Carbonized grease on the surface hinders the transfer of heat from the griddle surface to the food, resulting in spotty browning and loss of cooking effici

ADJUSTMENTS CALIBRATION-900RX AND MSA MODELS 1. Each thermostat controls a 12” zone of the griddle. Using a Surface Probe temperature measurement device, observe the temperatures at the center points of the cooking zones. These points are located by starting 6” from the side splash (left or right) and every 12” across the width of the griddle, with all points located 12” back from the front edge of the griddle plate. NOTE: Use of infrared thermometers is not recommended. These de

LEVELING The griddle must be level (side-to-side and front-to-back) during operation to ensure proper performance. Improper leveling can result in uneven temperature distribution, cold spots, and possibly damage electrical components. 1. Place a level on the griddle. 2. Adjust legs by turning the bullet feet at the bottom of each leg. Using pliers or a crescent wrench, turn the feet counter-clockwise to increase height, and clockwise to decrease height until leveling is achieved. Do not e
