e) To prevent leakage, make sure the orifice
spuds are securely screwed into the gas supply
tubes.
f) For the extra large burner (right front), the
choke and self threading screw will be needed.
Insert the choke into the burner base, then insert
the set screw into the burner base and tighten
securely. Make sure the screw head is against the
shoulder (within the choke notch), so it does not
have any rotational movement.

3. Converting the oven / broil burner orifices
a) Remove oven door, warming drawer and oven
bottom. The oven burner orifice hood is located
behind the warming drawer. The broil burner
orifice hood is located on the right upper corner of
the oven cavity.
b) To convert to LP, use a ½-in. wrench to turn
the orifice hoods clockwise until it is snug with
the base, approximately 2 ½ turns. To prevent
damage when converting back to Natural Gas, do
not over tighten the hood.
Burner cap
c) Open the air shutter on the burners to the full
open position and adjust as needed.

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

(A) Yelow Flames:
Further Adjustment
Required
B) Yellow tips on
outer cones:
Normal for LP Gas
(C) Soft Blue flames:
Normal for Natural Gas.
If burner flames look like (A). Further air
shutter adjustment is required. Normal burner
flames should look like (B) or (C), depending
on the type of gas you use. With LP gas,
some yellow tipping on the outer cones is
normal.
The broil burner will cycle off when the sensor
temperature reaches 460°F (238°C) set on Lo
Broil, and at 570°F (299°C) set on Hi Broil.
Upon completion of the conversion, fill out the
LP sticker located with the instructions. Once
complete, apply the sticker to the back of the
range near the regulator. If converting back
to natural gas from LP remove the LP sticker
from the back of the range.
