GE JGBS18, JGBC18 With baffle in place, flames Screw, Surface knobs to LOW, Check Quality of Fues

❑CONVERT AIR ADJUSTMENT SHUTTER

For LP gas, loosen the Phillips head screw and rotate the shutter to the full open position.

With baffle in place, flames Screw

should have approximately 1- ~~Utter inch blue cones and should not extend beyond the edges of the

burner baffle. After 30 seconds of burner operation, check for flames lifting off burner ports. H lifting is observed, gradually reduce air shutter opening until flames are stabilized.

For natural gas, the shutter should be open 1/2” or about 3/4 of the way open.

❑CHECK FOR L~KS

When all connections have been made, make sure all range controls are in the off position and turn on the main gas supply valve. Use a liquid leak detector at all joints and connections to check for leaks in the system.

CA~ON: DO NOT USE A FME TO CHECK FOR GAS ~.

When using test pressures greater than 1/2 psig to pressure test the gas supply system of the residence, disconnect the range and individual shut-off valve from the gas supply piping. When using test pressures of 1/2 psig or less to test the gas supply system, simply isolate the range from the gas supply system by closing the individual shut-off valve.

❑CHECK QUALITY OF FUES

The combustion quality of burner flames needs to be determined visually.

(A) YeUow ~e=dl for service

(B)Yeflow tips on outer cones—Normal for LP gas

(C)SoRblue tie-Normal for natural gas

If burner flames look like (A), call for service. Normal burner flames should look like (B) or (C), depending on the type of gas you use.

With LP gas, some yellow tipping on outer cones is normal.

❑ADJUST OVEN THERMOSTAT

(for Models Equipped with Standing Pilots)

1.Remove the OWN CONTROL knob.

2. Locate the thermostat	# ~ -
adjustment screw at left of
thermostat shaft. Turn the	%	J
screw until the small pointer
stops at LP or N, depending on	o
the type of gas you are converting to.

The most the screw will move is 1/2a turn.

3. Replace the OWN CONTROL knob.

3. With a small flat

blade screwdriver, turn

the valve set screws WA+> clockwise to decrease

flame size, counterclockwise to increase flame size. Adjust until the flame is about the same height as the top of the burner.

4.Replace the knobs.

5.Check for flame outage by opening and closing the oven door several times. If the flame goes out, increase the flame size.

3/16”. Turn pilot adjustment screw until pilot is 5/16” high. Do not reduce the flame to less than 5/16” or pilot outage may occur. A pilot flame burning higher than recommended may generate soot (carbon black) on the bottom of your cooktop.
