installed on the manifold pipe, the conversion nut will be 
easily accessible.
CAUTION: 
Do not attempt any adjustment of the pressure 
regulator, except conversion to propane.
Connect the gas supply line to the unit pressure regulator 
using a 1/2" flex gas line connector between manual shut-
off valve and pressure regulator. Always use a new flex 
line.
Check supply line connections for leaks using a soap 
solution. Do not use a flame of any sort. 
1.
Turn on gas. 
2.
Apply a non-corrosive leak detection fluid to all joints 
and fittings in the gas connection between the shut-off 
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.
3.
If a leak appears, turn off supply line gas shut-off valve 
and tighten connections. 
4.
Retest for leaks by turning on the supply line gas shut-
off valve. When leak check is complete (no bubbles 
appear), test is complete. 
5.
Wipe off all detection fluid residue.
Important Notes for Gas Connection:
The appliance and its individual gas shutoff valve must 
be disconnected from the gas supply piping system 
during any pressure testing of that system at test 
pressures in excess of 1/2 psig (3.5kPa).
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 psi (3.5kPa).
Connect Electrical Supply
Before connecting 5-foot (1.5 m) supply cord to wall 
receptacle, make certain that gas shutoff valve and all 
burner controls are in OFF position.
Burner Cap Placement
WARNING:
To prevent flare-ups, do not use the cooktop 
without all burner caps and all burner grates 
properly positioned.
WARNING:
To prevent burns, do not touch burner caps or 
grates while hot. Turn the cooktop off and allow 
the burners to cool.
The burner caps must be properly placed for the cooktop to 
function properly. If the burner cap is not properly placed, 
one or more of the following problems may occur:
Burner flames are too high.
Flames shoot out of burners.
Burners do not ignite.
Burner flames light unevenly.
Burner emits gas odor.
Placing Burner Caps
Each cap has a letter (B, D, or F) cast in the underside of 
the cap that corresponds to a letter (B, D, or F) cast in the 
burner base that is attached to the appliance. 
After electrical connection is complete, place each 
burner cap on its correct burner base per its 
corresponding letter designation.
