This appliance is shipped from the factory for use with natural gas. Use this kit to convert the appliance for LP gas use if necessary. Observe the following:
Be sure the range is converted for use with the appropriate gas before using it.
This appliance is designed to operate at a pressure of 10" of water column when used with LP gas.
When checking for proper operation of the regulator, the inlet pressure must be at least 1" greater than the operating (manifold) pressure above. When converting for LP gas use, the pressure supplied to the regulator must be between 11" and 14" of water column. See “Convert Pressure Regulator from 5" W.C. to 10" W.C.” on page 3.
The pressure regulator located in the inlet of the range manifold must remain in the supply line.
Use a flexible metal appliance connector or rigid pipe to connect the Range to the gas supply. The connector should have an I.D. of 1/2" and be 5' in length (Exception: Maximum connector length in Massachusetts installations is 3'). In Canada, the connector must be single wall metal and not longer than 6'.

Test the Installation
Test for Gas Leaks |
Leak testing is to be conducted by the installer according to the instructions given |
|
in this section. |
Apply Leak Detection Fluid |
Turn on Gas. Apply a non-corrosive leak detection fluid to all joints and fittings in |
|
the gas connection between the shutoff valve and the range. Include gas fittings |
|
and joints in the range if connections may have been disturbed during installation. |
|
Bubbles appearing around fittings and connections indicate a leak. |
|
If a leak appears, turn off supply line gas shutoff valve and tighten connections. |
|
Retest for leaks by turning on the supply line gas shutoff valve. When leak check |
|
is complete (no bubbles appear), test is complete. Wipe off all detection fluid resi- |
|
due. |
|
CAUTION: |
|
Never check for leaks with a flame. |
|
Do not continue to the next step until all leaks are eliminated. |
Test Electric Ignition |
Turn on power at breaker. |
|
CAUTION: |
|
If the display flashes and beeps, the polarity of the wiring may be reversed. |
|
Reversed polarity can damage the range and can result in electrical shock haz- |
|
ard. Immediately switch off power at the breaker and return to installation instruc- |
|
tions. |
Test Cooktop Burners: |
Each burner must be tested for proper lighting, proper flame characteristics on the |
|
low setting and proper flame characteristics on the high setting. |

Conversion
Test for proper ignition:
1.Push down and turn the knob to ignition symbol.
2.Verify that the ignitor/spark module clicks.
3.Once the air has been purged from the supply lines, verify that the burner lights within four (4) seconds. After burner lights, turn knob to the OFF position.
4.Test each rangetop burner in this fashion. Call Service if any of the burners do not light.
Test flame characteristics on the low setting:
1.Push in and turn the knob to the ignition symbol until the burner ignites.
2.Turn knob to the low setting.
3.Verify that the burner maintains a minimum, steady, flame without going out. The flame should not lift or blow off of the burner. It should carry over, or surround, the entire burner.
4.Verify that the flame is the right color. It should be blue with an inner and outer cone. See Figure 6: Checking Flame Characteristics for more information.
5.Test each rangetop burner in this fashion. If any flame goes out, does not carry over properly or is too large, contact service.
Test flame characteristics on the high setting:
1.Push in and turn the knob to the ignitor symbol until the burner ignites.
2.Turn knob to the high setting.
3.Verify that the burner maintains a steady flame. The flame should not lift or blow off of the burner. It should carry over, or surround, the entire burner.
4.Verify that the flame is the right color. It should be blue with an inner and outer cone. See Figure 6: Checking Flame Characteristics for more information.
5.Test each rangetop burner in this fashion.
Yellow Flames:
Further adjustment is required.
Yellow Tips on Outer Cones:
Normal for LP Gas.
Soft Blue Flames:
Normal for Natural Gas.
If the flame is completely or mostly yellow, verify that the regulator is set for the correct fuel. After adjustment, retest.
Some yellow streaking is normal during the initial start-up. Allow unit to operat 4-5 minutes and re-evaluate.
Figure 6: Checking Flame Characteristics
If any flame does not carry over properly, adjust the bypass jet. Return to “Convert Cooktop Valves for Propane Use” on page 4. If any flame burns yellow, contact Service.
