Excessive heat causes grease to carbonize and makes the surfaces hard to clean. 3. Empty the grease trays often to avoid spillovers. 4. For extended shutdown or major maintenance, turn the power and zone switches OFF, close the manual shut-off gas valve, and unplug the electrical power cord. Cleaning 1. At the end of the cooking operations, wipe and clean the unit while it is still warm. Use a spatula to remove food residue and burnt grease. 2. When the plate is cool, wash it with a mild detergent, dry it, and wipe it with a slightly oiled cloth. 3. For a more thorough cleaning, use Garland Ranges F69 fryer and griddle cleaner. Polish the plate to a bright finish, then wash, rinse and thoroughly dry it. 4. Follow the procedure specified (see Start-Up) to reseason the cooking surface. 5. To clean the exterior surface of a chain griddle, clean the stainless steel with a hot detergent or soap solution. Remove baked on grease by applying the cleanser in the direction of the polishing lines of the stainless steel surface. CAUTION : Do not rub stainless steel in a circular motion. This destroys the finished surface of the metal and detracts from its appearance. If it is necessary to remove hard and burnt on deposits from high quality surfaces, use SCOTCH-BRITE or STAINLESS scouring pads by running with the grain of the finished steel. Remove heat tint the same way, using if necessary a non-abrasive powered cleanser with the SCOTCH-BRITE or STAINLESS pad. On no account use ordinary steel wool, it will damage the finished surface. SERVICING Many factors affect the serviceability of equipment. In the chain griddle, there are more components to service than in older models. The new griddle is a compact design. Access to the temperature control circuitry and ignition units is easy. Service techniques for the thermocouple will vary depending on the model type. They unit is available with a 6” (152mm) leg which means that under the griddle plate there is only 6” (152mm) of working room. To replace a thermocouple it is difficult to lift the griddle plate, firmly secured to the support frame. To replace a thermocouple requires bottom access because the plate is securely fixed (see Figure 3). With this introduction to serviceability, and apart from the features that make the chain griddle superior to more conventional units, many of the servicing tasks are standard; the adjustments likewise. The procedures that follow are a plain guide to servicing, beginning with adjustments to various components. Have The Right Tools And Instruments In addition to a service technician’s normal hand tools, for servicing this chain griddle we recommend: 1. A manometer or other suitable instrument for measuring gas pressure 2. A multimeter 3. A digital read-out temperature meter 4 A micro-ammeter CAUTION : In this chain griddle we use a J-type thermocouple, which requires a meter with a J-type connection for checking. Most meters have K-type connections. Adjustments Every griddle is inspected and tested before it leaves the factory. Adjustments to the unit during installation and servicing are the responsibility of the field operator and are not considered to be defects in material or workmanship. For this reason, adjustments are not covered under the equipment warranty. Pilot Flame Adjustment A pilot adjustment valve is in the line form each pilot combination valve and access to it is behind the lower front panel. 1. To remove the upper front and lower front panels, refer to the installation procedure given earlier. 2. To reduce the volume of gas feed to the pilot, turn the small screw in the pilot adjusting valve clockwise. 3. To increase the gas feed to the pilot, turn the same screw counter-clockwise. NOTE : Adjust the gas feed to produce a 7/16” (11mm) long flame to make sure the flame envelopes the top of the flame sensor. Burner Air Make sure a burner is warm before adjusting the air shutters and follow this procedure. 1. First, loosen the screw along the side of the burner near the orifice. 2. A burner flame that gets too much air appears to lift above the burner as though separated from it. This means the shutter needs throttling back to a more closed position. 3. A yellow tip on the flame is a sign that the shutter is not passing enough air to feed the flame. In this case, it necessary to open the shutter. 4. When the shutter adjustment is complete, tighten the screw to lock the shutter setting in the adjusted position. 5. Re-close the upper and lower front panels and replace the fasteners. Removing the Griddle Plate If it is necessary to remove the griddle top, follow this procedure: 1. Disconnect the power supply. 2. Remove the upper control panel. 3. Open the lower control panel. 4. Disconnect all thermocouple sensors and shield bayonet adapters. (To reassemble, see the Thermocouple section.) 5. Remove the griddle top retaining bolts (both left and right). 6. Remove the back flue. 7. The griddle top is now easily removed. Therm...
