TEST AND ADJUSTMENTS

LEAK TESTING:
■ After final gas connection is made, turn on manual gas valve and test all
connections in gas supply piping for gas leaks with a soapy water solution.
During this test all appliance gas valves have to be closed.
■ In order to avoid property damage or serious personal injury, never use a
Iighted match or open flame. If a leak is present, tighten joint or unscrew,
apply more joint compound, tighten again and retest connection for leak.
WARNING:
For warranty coverage, DCS requires that burner adjustments be made by a qualified technician at the time of
installation. Extreme care should be used when adjustments are made after installation.
COOKTOP BURNERS
The cooktop burners are not adjustable. Proper operation is achieved when the correct orifices for gas supply
are installed at the factory, based on model ordered.
When installing the burner port ring, be sure that the two locating pins in the bottom side of the brass port
ring are properly aligned with the locating notch and center holes on the top side of the simmer ring. Incorrect
alignment will produce a potentially dangerous flame and poor burner performance.
Note:
No air shutter adjustment is possible on the cooktop burners. Burner flames should be blue and stable with no yellow-
tipping (some yellow-tipping is normal with LP gas), excessive noise, or lifting of flame from the burner (Fig. 11).
COOKTOP BURNER LIGHTING NOTE
The cooktop burners have an infinite number of heat settings and there
are no fixed positions on the control knobs 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 the electronic spark igniter, turn the
knob to the desired setting.
Note:
The igniter will continue to click until a flame is present. If the cooktop burner
does not ignite, check the spark igniter by listening for a clicking sound. If you
do not hear the igniter click, turn off the burner. Check for a tripped circuit
breaker, blown fuse, or poor wire connection to the igniter.
WARNING:
When turning on any cooktop burner, be sure to stop at the "LITE" position
before turning the burner to a flame setting for cooking. If the burner is not
lit and it is turned beyond the "LITE" position, to HI, MEDIUM, or LO, there
will be a burst of flame when the burner does light. This could cause burns
or damage to the surrounding countertop.
THIS ADJUSTMENT SECTION APPLIES TO THE GRIDDLE
AND GRILL BURNERS.
Check for the proper burner flame characteristics and adjust air shutters
if necessary (fig. 12). Each valve and air shutter is individually tested and adjusted prior to shipment. Normally
adjustment is not required, however, vibration during transit, gas conversion or variations in the local gas supply
may make minor adjustments necessary. Burner flames should be blue and stable with no yellow tips, excessive
noise or lifting of the flame from the burner. If any of these conditions exist, check that the air shutter or burner
ports are not blocked. If this condition persists, adjust the air shutter as required. If the flame is too yellow,
indicating insufficient air, adjust the shutter counterclockwise 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 flames should be 3/8" to 5/8" (fig. 13).
