17TEST AND ADJUSTMENTSWARNING:For warranty coverage, DCS requires that burner adjustments be made by aqualified technician at the time of installation. Extreme care should be usedwhen adjustments are made after installation.COOKTOP BURNERSThe cooktop burners are not adjustable. Proper operation is achieved whenthe correct orifices for gas supply are installed at the factory, based on modelordered.When installing the burner port ring, be sure that the two locating pins in thebottom side of the brass port ring are properly aligned with the locating notchand center holes on the top side of the simmer ring. Incorrect alignment willproduce a potentially dangerous flame and poor burner performance.Note:No air shutter adjustment is possible on the cooktop burners. Burner flames shouldbe blue and stable with no yellow-tipping (some yellow-tipping is normal with LPgas), excessive noise, or lifting of flame from the burner (Fig. 13).COOKTOP BURNER LIGHTING NOTEThe cooktop burners have an infinite number of heat settings and there are no fixed positions on the controlknobs between HI and LO. To turn the cooktop burner on, push in on the control knob and turn it counter-clockwise to the “LITE” position. An audible clicking sound will be heard. When the gas has been ignited by theelectronic spark igniter, turn the knob to the desired setting (Fig. 14).Note:The igniter will continue to click until a flame is present. If the cooktop burnerdoes not ignite, check the spark igniter by listening for a clicking sound. If youdo not hear the igniter click, turn off the burner. Check for a tripped circuitbreaker, blown fuse, or poor wire connection to the igniter.WARNING:When turning on any cooktop burner, be sure to stop at the “LITE” positionbefore turning the burner to a flame setting for cooking. If the burner is notlit and it is turned beyond the “LITE” position, to HI, MEDIUM, or LO, therewill be a burst of flame when the burner does light. This could cause burnsor damage to the surrounding countertop.THIS ADJUSTMENT SECTION APPLIES TO THE GRIDDLEAND GRILL BURNERS.Check for the proper burner flame characteristics and adjust air shutters ifnecessary (fig. 15). Each valve and air shutter is individually tested andadjusted prior to shipment. Normally adjustment is not required,however, vibration during transit, gas conversion or variations in the localgas supply may make minor adjustments necessary. Burner flames shouldbe blue and stable with no yellow tips, excessive noise or lifting of theflame from the burner. If any of these conditions exist, check that the airshutter or burner ports are not blocked. If this condition persists, adjustthe air shutter as required. If the flame is too yellow, indicating insufficient air, adjust the shutter counter-clockwise to increase air inlet. If the flame is noisy or tends to lift away from the burner, indicating too much air,turn the shutter clockwise to reduce air. The griddle flames should be 1-1/2" to 2". The grill burner flamesshould be 3/8” to 5/8” (fig. 16).1-1/2"COOKTOP BURNERFIG. 13FIG. 14SIMLOLITEHIOFFFig. 151-1/2" ~ 2"Typical Section of Proper Flame3/8" ~ 5/8"(Grill)(Griddle)Fig. 16Typical Section of Proper FlameGriddle1-1/2” – 2” 3/8” – 5/8”Grillair shutter
