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.
