Important Safety Instructions
•Please read Installation Instructions before beginning the conversion
•Please read all instructions before proceeding. Save the natural gas parts for possible conversion from LP back to natural gas in the future
•This kit is used to convert dual fuel ranges and gas ranges from natural gas operation to propane (LP) gas operation. Only ranges manufactured by BSH Home Appliances can be converted using this kit.
•CAUTION: When connecting the unit to the propane gas,make certain the propane gas tank is equipped with its own high pressure regulator. In addition, the range has its own pressure regulator. Verfiy that it is installed for the appropriate gas supply.
•The maximum gas pressure to this appliance is not to exceed 14.0 inches water column from the propane gas tank regulator.
•The following must be met when testing supply piping system:
a)The appliance and its individual shut-off valve must be disconnected from the gas supply piping system at test pressures in excess of 1/2 psig (3.5 kPa).
b)The appliance must be isolated from the gas supply piping system by closing its individual manual shut-off valve during any pressure testing of the gas supply piping system at test pressures equal to or less than 1/2 psig (3.5 kPa).
•WARNING: This conversion kit shall be installed by a qualified service agency in accordance with the manufacturer's instructions and all applicable codes and requirements of the authority having jurisdiction. If the information in these instructions is not followed exactly, a fire, explosion or production of carbon monoxide may result causing property damage, personal injury or loss of life. The qualified service agency is responsible for the proper installation of this kit. The installation is not proper and complete until the operation of the converted appliance is checked as specified in the manufacturer's instructions supplied with the kit.
•For Massachusetts Installations:
1)Installation must be performed by a qualified or licensed contractor, plumber or gas fitter qualified or licensed by the state, province or region where this appliance is being installed.
2)Shut-off valve must be a "T" handle gas cock.
3)Flexible gas connector must not be longer than 36 inches.
•High Altitude Installation Note: This range is CSA certified for safe operation up to an altitude of 10,000 ft. without any modifications (except LP conversion, when applicable).

Gas Supply
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 step 2 "Convert Pressure Regulator from 5" to 10" W.C.", next page.
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'.
CAUTION: Turn off Gas and Electricity
Before proceeding with the conversion; shut off the gas supply to the appliance prior to disconnecting the electrical power.

If your range is dual fuel your conversion is complete. Replace the cover plate and warming drawer and proceed to “Test the Installation” on page 6.
For gas range conversions, continue to next step.
2.Remove Broil Burner Assembly. The broil burner assembly is attached to the top of the oven cavity with 7 screws. Remove screws and gently pull broil burner assembly straight out being careful not to detach electrical wires. Place broil burner against back wall of oven cavity.
3.Adjust Broil Orifice. The orifice is located behind the broil burner in the back

extension to turn orifice clockwise until it stops (2- 2 1/2 turns). DO NOT OVERTIGHTEN.
CAUTION: DO NOT overtighten the broil burner orifice. Overtightening may result in damage to the pin inside the orifice. This affects cooking performance. It could cause inconsistent flames and unintentional release of carbon monoxide.

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.
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 hazard. Immediately switch off power at the breaker and return to installa- |
|
tion instructions. |
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. |
|
Test for proper ignition: |
English 6 |
|
Conversion
Test flame characteristics on the low setting:
Test flame characteristics on the high setting:
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.
Dual Fuel appliance installation is complete when correct color, carryover and size are verified on each cooktop burner.
For gas appliances, continue to “Test Broil Burner” on page 8

Test Ignition |
Set cooking mode to Hi Broil. The burner will ignite after 30-75 seconds. |
