Air Shutter Adjustment This appliance is shipped from the factory with air shutters adjusted for use with Natural Gas. If further adjustment is necessary, or to reset for use with LP, adjust air shutters as follows: Grill Burner and Surface Burner Cartridge Air Shutters (See Illustrations "A" & "B") The left hand air shutter controls the rear half of the burner. The right hand shutter controls the front half. Access to air shutters on the surface burner cartridge may be found through openings on the bottom of the cartridge housing. Slide air shutters backward or forward to increase or decrease the size of the air opening. Air shutters fit snugly, so a screwdriver blade may be required to make this adjustment (see illustration). Observe change in flame appearance as the air shutter is moved. Adjustment is satisfactory when a clearly defined, even blue flame results at the high flame setting. The snug fit of the air shutter assures it will remain positioned correctly. Grill Burner Air Shutter and Surface Burner (if so equipped) Low Flame Adjustment (See Illustration "C") This appliance is shipped from the factory with low and medium flame settings adjusted for use with Natural Gas. If further adjustment is necessary, or to readjust for use with LP, proceed as follows: 1. Light burner and set control knob for low flame. 2. Remove control knob from valve stem. CAUTION NEVER USE A METAL BLADE TO PRY KNOB OFF. IF KNOB CANNOT BE EASILY REMOVED, TUCK THE FOLDS OF A CLOTH DISHTOWEL UNDER THE KNOB AND PULL THE TOWEL UPWARD WITH STEADY, EVEN PRESSURE. 3. Insert a slender, thin-blade screwdriver into the recess at center of valve stem and engage blade with slot in adjusting screw. 4. Turn center stem adjusting screw to set flame size. S clockwise to reduce. S counterclockwise to increase. 5. Replace control knob when adjustment is completed. Proper adjustment will produce a stable, steady blue flame of minimum size. The final adjustment should be checked by turning knob from high to low several times without extinguishing the flame. This adjustment, at low setting, will automatically provide the proper flame size at medium setting. AIR OPENING AIR SHUTTER ILLUSTRATION "A" INSERT SCREWDRIVER BLADE IN SLOT AND TWIST WITH SLIGHT PRESSURE TO ALLOW AIR SHUTTER TO SLIDE EASILY CLOCKWISE TO REDUCE FLAME SIZE COUNTERCLOCKWISE TO INCREASE FLAME SIZE On any burner, closing the air shutter too far will cause the flame to become soft and yellow tipped. Opening the air shutter too wide will cause the flame to blow away from the burner ports. Proper adjustment will produce a sharp, clearly defined, even blue flame. ILLUSTRATION "B" VALVE STEM ILLUSTRATION "C" Pressure Testing The maximum gas supply pressure for the appliance pressure regulator supplied on this appliance is 14² W.C. The test pressure for checking this appliance pressure regulator must be at least 6² W.C. for Natural Gas, and at least 11² W.C. for LP. It is shipped from the factory set for Natural Gas at 5² W.C. output pressure. This appliance and its individual shutoff valve must be disconnected from the gas supply piping system during any pressure testing of that system at test pressures in excess of 1/2² PSIG (3.5 k Pa). This appliance must be isolated from the gas supply piping system by closing its individual manual shutoff valve during any pressure testing of the gas supply piping system at test pressures equal to or less than 1/2² PSIG (3.5 k Pa). 4
