LP Conversion Instructions 5 ADJUST THE LOW FLAME (SIMMER) SETTING The top burner valves have low flame/simmer adjustment screws accessible through the valve switches. A flashlight may be needed to locate the screw. A small, thin-blade screwdriver (approximately 1/8″ blade width) is needed to access the screw. A Light two other burners and set the knobs to a medium to high setting. B Light the burner to be adjusted and turn the knob to LOW. C To make adjustment, remove the control knobs. Insert a screwdriver through the access hole in the valve switch. Engage the adjustment screw in the valve. If the flames were too small or fluttered, open the valve more than the original setting. If the flames are too large, close the valve more than the original setting. D Make the adjustment by slowly turning the screw until the flame appearance is correct. For the left side, install the grill burner for the adjustment. The left side cannot be turned down as low as the right side if the grill burner is to be used. Adjust the low flame setting using the valve bypass screw as follows: Low setting adjustments must be made with two other burners in operation on a medium setting. This prevents the low flame from being set too low, resulting in the flame being extinguished when other burners are turned on. E Testing Flame Stability: Test 1: Turn the knob from HI to LOW quickly. If the LOW flame goes out, increase the flame size and test again. Test 2: With the burner on the LOW setting, open and close the cabinet door under the cooktop. If the flame is extinguished by the air currents created by the door movement, increase the flame height and test again. Test 3: With the burner on the LOW setting, turn the downdraft vent fan to the HI position. If the flame is extinguished by the air currents created by the downdraft vent fan, increase the flame size and test again. 5 ADJUST THE LOW FLAME (SIMMER) SETTING (cont.) F Flame Recheck: Repeat the adjustment for each burner. After the adjustment is made, turn all burners off. Ignite each burner individually. Observe the flame at the HI position. Rotate the valve to the LOW position and be sure that the flame size decreases as the valve is rotated counterclockwise. 6 CONVERTING BACK TO NATURAL GAS To convert the cooktop back to natural gas, reverse the steps taken to convert to LP. Natural Gas 5″ W.C.P. Burner Output Rating in BTU/HR Location BTUs Orifice Size Engraving Left Rear (LR) 10,000 .0550 NAT Left Front (LF) 10,000 .0550 NAT Right Rear (RR) 10,000 .0550 NAT Right Front (RF) 10,000 .0550 NAT Once the conversion is complete and checked OK, fill out the LP sticker and include your name, organization and date conversion was made. Apply the sticker near the cooktop gas inlet opening to alert others in the future that this appliance has been converted to LP gas. If converting back to natural gas from LP, please remove the sticker so others know the appliance is set to use natural gas. NOTE: For operation at elevations above 5000 ft. (1500 m), equipment ratings shall be reduced at a rate of 2% for each 1000 ft. (300 m) above sea level before selecting appropriately sized equipment, i.e.: Use smaller orifices. 33
