Check that all screws and bolts are tightened. 2. Check that gas connection has been made correctly. 3. Move the Cheese Melter into the final position at which it will be operated. 4. Check that the Cheese Melter is level. 5. Check that the appropriate minimum clearances are satisfied (see page 5), including adequate clearance for combustion air to enter the rear of the Cheese Melter. 6. Check that there is sufficient clearance to pull out the Cheese Melter rack and bottom drip pan. 7. Check that adequate ventilation (fresh air supply and hood exhaust) is available to the room in which the appliance will operate. 8. Wipe clean all surfaces. STEP 6: CHECK CHEESE MELTER OPERATION 1. Turn gas supply on. Immediately check all gas connections for leaks using soapy water. 2. Light the pilots (see the appropriate Operation section elsewhere in this manual). Check that the pilot flames are large enough to extend along the flame carrier to the burner surface. If not, adjust the pilots (see page 19). 3. Turn on the Cheese Melter burners and check for correct flame appearance and height at both the HIGH and LOW settings. When the burners ignite, a blue haze-type flame will cover the surface of the ceramics, but will gradually disappear within two minutes. When the burner control is set to HIGH, the ceramics should glow red and the flame on the surface of the ceramics should be barely visible, with little or no blue haze. When the burner control is set to LOW, the surface of the ceramics should glow very dull red and the flame should have a blue- haze color. If flame should flutter or “pop”, increase temperature setting. 4. Check that gas supply is adequate by simultaneously turning on all burners of all appliances connected to the same gas supply to their highest setting, then again checking that the Cheese Melters pilot and burner flames have correct appearance and height. 5. Turn off all burners and allow the Cheese Melter to cool. STEP 7: WIPE-CLEAN AND SHUT-DOWN APPLIANCE 1. Wipe clean all surfaces. 2. Unless the Cheese Melter is to be placed in service immediately, shut off the gas supply. 3. Make sure that a copy of this manual is available to the people who will operate and maintain the Cheese Melter.
