RANGE TOP CONVERSION TO “LP”
Models 1955 & 1956
All our ranges are factory set to burn natural gas unless
“LP” is specified. To use the range on “LP” gas, please do
the following:
Order an “LP” kit from the factory. $35 UPS included.
Burner Large Medium Small
Nat. Gas #50 (1.75 mm) #55 (1.32 mm) #57 (1.09 mm)
LP/Propane #64 (.91 mm) #65 (.89 mm) #70 (.71 mm)
Store natural gas spuds so they are available for future
conversions.
Installation of “LP” Spuds
Apply masking tape to the end of a 7 mm nut driver to
help hold the gas orifice spud in the nut driver while
changing it. Press nut driver down onto the gas orifice
spud and remove by turning it counterclockwise and
lifting out, set gas orifice spud aside.
Gas orifice spuds are stamped with a number on the side.
Replace the LP gas orifice spud with the correct Natural
gas orifice spud.
Refer to the following chart for the correct Natural gas
orifice spud placement.
