ADJUSTMENTS WARNING De-energize all power to equipment before attempting to service or replace any component of the equipment. CAUTION When changing motor or servicing unit, always verify that the blower wheel rotation is as the illustration shows. (clock-wise when looking into oven cavity) ONLY on units manufactured before serial numbers 91 H BLOWER WHEEL ROTATION FIGURE 1 Blower wheel must not be located over 1/8" from rear of oven. This is critical for proper burner combustion. A. MOTOR: The motor is serviceable from the front of the unit through the oven cavity. Remove the rear baffle. Disconnect the motor mount plate by removing the eight hex nuts that secure it to the oven interior back. Pull the mount plate, with motor attached, into the oven. B. CONTROL PANEL ASSEMBLY COMPONENTS: The control panel assembly components are easily serviceable by removing two screws (one at the top and at the bottom) of the control panel and then sliding out the control panel assembly. C. THERMOSTAT: After sliding out the control box assembly, the thermostat can be completely removed by removing the capillary bulb brackets from inside of the oven, and then sliding the capillary bulb out of the oven cavity into the control area. CAUTION Before sliding out control box for servicing, remove base panels below oven door and remove the wire tie from the spark ignitor electrode wire (black wire). To return control box to original position, push in slowly while lightly pulling the spark ignitor wire (black wire) into the oven burner control area (below oven door). Re-attach a wire tie in a similar fashion as before it was removed. Replace base panels. PAGE 4
ADJUSTMENTS THERMOSTAT ADJUSTMENT OVEN: The calibration of the thermostat should not be changed until sufficient experience with cooking results have definitely proved that the thermostat is not maintaining proper oven temperatures. Before any recalibration is attempted, the oven temperature should be checked by the following procedure: 1. The oven must be empty of all trays or pans. 2. Place a pyrometer thermocouple or a reliable mercury oven-type thermometer at the center of the middle rack. 3. Turn on the blower. 4. Set the dial at 375 F. 5. The red "Cooking Light will go out when the thermostat turns off the burners. 6. Allow three such cycles for the temperature to stabilize. 7. Read the pyrometer or thermostat immediately after the light goes out for the third time and again immediately after it comes on the next time. 8. If the average of these readings and the dial setting vary by more than 15, recalibrate by following the instructions outlined below: TO RECALIBRATE: NOTE: Recalibration should be attempted only by a competent serviceman. 1. Remove knob from dial shaft (Item "B") from figure 2. 2. Turn screw (Item "A") in figure 2 clockwise to decrease and counterdockwise to increase temperature. 3. 1/4 turn changes the temperature 35 F. 4. Replace knob on dial shaft. 5. After the calibration is made, set the dial at 375 F and recheck the oven temperature using the method outlined by steps 1 thru 7 of the oven temperature checking procedure (as stated above). OVEN STANDING PILOT ADJUSTMENT: The standing oven pilot flame can be adjusted by turning the adjusting screw on the pilot line valve with a screwdriver. The pilot line valve is located behind the front FIGURE 2 panel below the oven door. Remove the front panel to gain accessibility. The pilot flame is property adjusted when it is just large enough to maintain a glowing red color on the flame switch capillary bulb. OVEN BURNER FLAME ADJUSTMENT: The oven burner orifice is of the fixed, type sized for the respective gas supply. The burner flame characteristics are controlled by varying the primary air mixer cap. There should be a clear blue flame with a distinct inner cone at each port. Excessive primary air can result in "blowing" or the flames leaving the ports. Lack of primary air causes soft or yellow tipped flame. THERMOSTAT REMOVAL AND REPLACEMENT: (GRIDDLE DOESN'T HAVE TO BE REMOVED) Refer to figures 3 and 4 for instructions below. 1. Remove thermostat knob(s). 2. Remove valve panel. 3. Remove thermostat screw (Item "A") and orifice bracket screws (Item "B"). 4. Pull thermostat assembly out to side and remove the burner (Item "C") [this applies for both sides]. PAGE 5 FIGURE 3
ADJUSTMENTS THERMOSTAT REMOVAL AND REPLACEMENT: (Continued) 5. Loosen bolt(s) on bottom of griddle plate (Item "D") 1/2 inch then pull thermostat bulb out front. NOTE: If bulb will not pull out loosen bolt (Item "D") further (DO NOT FORCE). 6. Reverse steps 3 thru 5 to install new thermostat. NOTE: Snug bolt (Item "D") DO NOT over tighten, (this will damage capillary bulb causing incorrect sensing). 7. Make sure the excess capillary wire is stored in the cool zone under thermostat body in front of burners. 8. Replace valve panel. 9. Replace thermostat knob(s), FIGURE 4 PRESSURE REGULATOR: The pressure regulator is factory set a 7-8" W.C. for natural gas and 11-12" W.C. for propane gas. To check the manifold pressure: 1. Turn all thermostats and burner valves to "OFF" position. 2. Turn main gas valve to entire unit off. 3. Remove valve panels and locate 1/8" plug in manifold. 4. Remove plug and install a fitting appropriate to connect a manometer. 5. Turn on main gas to unit and light pilots. 6. Turn all burners and ovens to full "ON" position and read manometer. 7. If manometer does not read 4" W.C. for natural gas, or 10" W.C. for propane gas, adjust regulator (if gas pressure is O.K. go to step 10) 8. Remove cap form top of regulator. 9. With a screwdriver rotate regulator adjustment screw "Clockwise" to increase, or "counterclockwise" to decrease, pressure until manometer shows correct reading. 10. Repeat steps 1 and 2. 11. Remove manometer fitting and replace plug in manifold. 12. Repeat step 5. 13. Replace valve panels. FIGURE 5 PAGE 6
ADJUSTMENTS THERMOSTAT CALIBRATION GRIDDLE: To Check Calibration 1. Turn thermostat to the 300 F of marking see figure 5. 2. After burners have been on a minimum of 1 hour (if cold) or 30 minutes (if already hot when set at 300 F). Place a reliable thermometer or therm-couple with test instruments in the center of the griddle and over the center of each burner. See figure 6. 3. Continue to check temperatures at 5 minute intervals, until you have two readings that are within 30 of each other. 4. The control should only be recalibrated if your reading is not within 30 of the dial setting (300 F). FIGURE 6 TO RECALIBRATE THERMOSTAT: This control has been carefully calibrated at the factory. That is, it is adjusted to match the actual griddle temperatures. Field calibration is seldom necessary and it should NOT be done unless considerable experience with cooking and temperatures definitely proves that the control is not maintaining the temperatures to which the dial is set. 1. When recalibrating, check temperatures as instructed in previous section (thermostat calibration) 2. Set temperature indicator knob to 300 F marking 3. Remove indicator knob (Item "A") from thermostat (Item "B"). Refer to figure 7. 4. Using a screwdriver knock out silver insert (Item "C"). Refer to figure 7. 5. Place knob back on the thermostat shaft. 6. With screwdriver inserted through center FIGURE 7 of dial and in the calibration slot of screw push in and hold - DO NOT rotate screw. 7. Rotate indicator mark until it points to actual temperature you are reading off the temperature sensing device you placed over the center of the burners. 8. Turn thermostat to 300 P and check temperature again at 5 minute intervals. 9. Remove indicator knob and reinstall center insert. 10. If the griddle will not adjust to within 30 F this means that the sensing bulb is inoperative and the control should be replaced. FIGURE 8 PAGE 7

PERFORMANCE CHECK: The following items should be checked within the first 30 days of operation by a qualified service technician. 1. Verify equipment is level. 2. Verify proper electrical characteristics - voltage, cycle, phase. 3. Check thermostat operation; calibrate if required. 4. Check ventilation. 5. Check electrical connections - external and internal. 6. Check door for proper alignment, tension, seal, and adjustment. 7. Check timers, switches and motor for proper installation and operation. 8. Check for any damage to unit from shipping or installation. 9. Check for proper clearance from combustible materials. 10. Verify proper type of gas. 11. Verify gas supply and pressure. (Pressure regulator is already installed at factory.) 12. Check gas connection and check for leaks. It is common for new products to require a bum-off time to dry out insulation and metal cooking surfaces. PAGE 10
