PRESSURE REGULATOR
Since service pressure may fluctuate with local
demand, every gas cooking appliance must be
equipped with a pressure regulator on the
incoming service line for safe and efficient
operation.
The pressure regulator shipped with the
appliance has two female threads ½” NPT. The
regulator shall be installed properly in order to be
accessible when the appliance is installed in its
final position.
Manifold pressure should be checked with a
manometer and comply with the values indicated
below:
Natural gas Æ 4.0" W.c.P.
LP/Propane Æ 11.0" W.C.P.
Incoming line pressure upstream from the
regulator must be 1" W.c.P. higher than the
manifold pressure in order to check the
regulator.
The regulator used on this range can withstand a
maximum input pressure of 1/2 PSI (14.0" W.c.P.)
If the line pressure exceeds that amount, a step‐
down regulator is required.
The appliance, its individual shut‐off valve, and
the pressure regulator must be disconnected
from the gas line during any pressure testing of
that system at pressures in excess of 1/2 psig
(3.45 kPa).
The individual manual shut‐off valve must be in
the OFF position during any pressure testing of
the gas supply piping system at test pressures
equal to or less than ½ psig (3.45 kPa).
GAS CONVERSION
WARNING!
Before carrying out this operation, disconnect
the appliance from gas and electricity.
Gas conversion shall be conducted by a factory‐
trained professional.
Call the customer service hotline to identify a
factory‐trained professional near your home.
The gas conversion procedure for this range
includes 6 steps:
1. Pressure regulator
2. Surface burners
3. Adjustment of minimum setting
The conversion is not completed if all 6 steps
have not been concluded properly.
Before performing the gas conversion, locate the
package containing the replacement nozzle
shipped with every range. IMPORTANT: Each
nozzle has a number indicating its flow diameter
printed on the body. Consult the table on page 20
for matching nozzles to burners.
Save the nozzles removed from the range for
future use.
STEP 1: PRESSURE REGULATOR
The pressure regulator supplied with the
appliance is a convertible type pressure regulator
for use with Natural Gas at a nominal outlet
pressure of 4” w.c. or LP gas at a nominal outlet
pressure of 11” w.c. and it is pre‐arranged from
the factory to operate with one of these
gas/pressure as indicated in the labels affixed on
the appliance, package and Instruction booklet.
To convert the regulator for use with other liquid
propane LP gas:
1. Unscrew by hand the upper cap of the
regulator, remove the white plastic
attachment from the cap, reverse its
direction and screw it again firmly against the
cap. The white plastic attachment has arrows
indicating the position for natural gas (NAT)
and LP gas (LP).
2. Screw by hand the metal cap in the original
position on the regulator.
