Installation of the range.
Read these instructions completely and carefully.
Convert Burner Orifices and Pressure Regulator (if necessary)
Converting Burner Orifices to LP Gas:
Tighten the orifice hoods for the surface burners
and oven burner approximately two complete
turns to the closed position and adjust top pilots,
if equipped. The gas pressure regulator must be
converted to the LP gas setting so that it will
provide a pressure of 10 inches water column to
the range manifold.
Converting Burner Orifices to Natural Gas:
(only if range has been operated previously on LP gas)
Unscrew the orifice hoods for all burners (top
and oven) approximately two complete turns,
until the flame on the burner does not increase in
length. Adjust the top pilots (if equipped). The
gas pressure regulator must be set to the natural
gas setting so that it will provide a pressure of 4
inches of water column in the range manifold.
Regulator Conversion:
All ranges are equipped with a gas pressure
regulator for controlling and maintaining a
uniform gas pressure in the gas manifold of the
range. The burner orifices are sized for the gas
pressure delivered by the regulator supplied.
The pressure regulator must not be removed.
To convert the regulator from one gas to another,
refer to the following illustration that applies:
Harper-Wyman Regulator:
For a Harper-Wyman regulator, remove converter
cap by inserting a coin into slot in top and
twisting. Turn cap over and re-install.
SCP Regulator:
On the SCP regulator, unscrew the converter
using a 5/8″wrench. Turn the cap over and
reinstall.
NOTE: What you read on the converter cap or plunger is
the type of gas for which the regulator is set. If yours reads
NAT, the regulator is set for natural gas. If yours reads LP,
the regulator is set for LP.
■
For proper operation, the maximum inlet pressure
to the regulator must be no more than 14 inches of
water column pressure.
For checking the
regulator, the inlet pressure must be at least
1-inch of water column (3.4 KPA) greater than
the regulator output setting. If the regulator is
set for 4 inches of water column pressure, the
inlet pressure must be at least 5 inches. If the
regulator is set for 10 inches, the inlet pressure
must be at least 11 inches.
■The gas supply line to the range should be 1/2
inch or 3/4 inch pipe.
For standing pilot models,
make the necessary oven
pilot adjustment (see directions in the
If Range
Has Standing Pilots—Light and Adjust Surface
Burner Pilots
section). Also burner air shutter
adjustments may be necessary on all models to
complete conversion (see the
Surface Burner Air
Shutter Adjustment
section).
