CONVERTING TO LP GAS (Standard Twin Burner models only)

or Converting Back to Natural Gas from LP

3CONVERTING SURFACE BURNERS

1.Lift cooktop.

2.Lift burner assemblies straight up and set aside to gain access to surface burner spuds.

3.With a 7mm, 5/16″ or a small adjustable

wrench, remove each of the four spuds on the surface burner

gas inlet tubes and

replace them with	Natural gas	LP gas =
the correct gas	= brass	red or silver
spuds mounted in		OR
a holder at the
right rear of the
range, above the
regulator. Natural
gas spuds are
brass and LP gas
spuds are red or
silver. (Mount the

spuds that you removed from the inlet tubes back in the holder.) To prevent leakage, make sure spuds are securely screwed into gas inlet tubes.

4.Replace the burner assemblies.

5.Keep all spuds with your range so you have them if you move or get a different gas hook-up.

Top Burner	Orifice Drill Size	Color
Natural Gas	#54 (.0550 Dia.)	Brass
LP (Propane)	#66 (.0330 Dia.)	Red or Silver

Broil Burner (on some models)

To convert to LP gas, use a 1/2″ wrench to turn the upper burner orifice spud clockwise. Tighten spud only until it is

snug with the base. To prevent damage,

do not overtighten spud.

To convert to natural gas, loosen the spud

about 2 turns.

5 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 should have approximately

1-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. If 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.

4 CONVERT THE OVEN BURNER ORIFICES

Oven Burner

1.Remove oven door, storage drawer or broiler drawer and oven bottom. The lower burner orifice spud is located behind the storage drawer, broiler drawer or kick panel. (On some models, a metal shield must be removed to access the orifice.)

2.To convert to LP gas,

″wrench touse a 1/2

turn the lower burner orifice spud clockwise. Tighten the spud only until it is snug. To prevent damage, do not overtighten the spud.

To convert to natural gas,

loosen the spud about 2 turns.

6 CHECK FOR LEAKS

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.

CAUTION: DO NOT USE A FLAME TO CHECK FOR GAS LEAKS.

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.
