CONVERTING TO LP GAS
Broil Burner
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.

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.
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.

ADJUST LOW FLAME SETTING
1. Light the top burners and continue turning all
of the surface knobs to LOW.
2. Remove all four knobs.
3. With a small flat
blade screwdriver,
turn the valve set
screws 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.
8
CHECK QUALITY OF FLAMES
The combustion quality of burner flames needs
to be determined visually.
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.
The conversion for sealed burner models is now
complete.
(A) Yellow flames—
Call for service
(B) Yellow tips on
outer cones—
Normal for LP gas
(C) Soft blue flames—
Normal for natural gas
