Step 4 - Convert valves for LP gas

The bypass jet on each valve must be adjusted. Your

cooktop may come with either hollow or solid valve

shafts. Determine the bypass screw location accordingly.

Turn all knobs to the "OFF" position.

Remove knobs.

Note: All cooktops have hollow stem valves except

the center valve on the NGMP units which is a solid

stem. Solid stem valves do not need to be adjusted.

Hollow Stem Valves (all burners except center valve

of NGMP units): insert a long, thin flat blade

screwdriver in the hollow stem of the valve. The

adjustment screw is approximately 1 1/2" (39 mm)

from the top of the stem.

Engage the tip of the screwdriver into the adjustment

screw by slowly turning the screwdriver and feeling for

the blade to engage the screw. Then turn the screw

clockwise about 70 degrees (less than 1/4 turn) until it

"bottoms out" (does not turn any further). The screw

does not take much force to turn. Once the screw

does not turn any further, stop. Do not overtighten.

Repeat for each valve until all have been adjusted

correctly.

Hollow Stem Valve: Replace the knob.
