GAS CONNECTION
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 34" 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: 4.0" W.c.P.
• LP / Propane: 10.0" 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 (13.8"
w.c. or 3,5 kPa) 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 PSI
(13.8" w.c. or 3,5 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 1/2 PSI (13.8" w.c. or
3,5 kPa).
APPLIANCE SERVING
Before carrying any service, disconnect the appliance from gas appliance from final install
have access to the appliance for proper servicing intervention.
