PRESSURE REGULATOR
Since service pressure may fl uctuate with local
demand, every gas cooking appliance must be
equipped with a pressure regulator on the inco-
ming service line for safe and e
ffi cient operation.
The pressure regulator shipped with the applian-
ce has two female threads ½” NPT. The regulator
shall be installed properly in order to be accessible
when the appliance is installed in its
fi nal position.
Manifold pressure should be checked with a ma-
nometer and comply with the values indicated be-
low:
Natural gas 4.0” iwc
LP/Propane 10.0” iwc
Incoming line pressure upstream from the regula-
tor must be 1” iwc higher than the manifold pres-
sure in order to check the regulator.
The regulator used on this range can withstand a
maximum input pressure of 1/2 PSI (13,8” iwc or
3,5 kPa) If the line pressure exceeds that amount,
a stepdown regulator is required.
The appliance, its individual shut-o
ff valve, and
the pressure regulator must be disconnected from
the gas line during any pressure testing of that sy-
stem at pressures in excess of 1/2 PSI (13,8” iwc
or 3,5 kPa).
The individuaL manual shut-o
ff 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” iwc or 3,5 kPa).
Warning
Before carrying out any servicing operation di-
sconnect the appliance from gas and electric
supply and extra appliance from
fi nal installation
place in order to have access to the appliance for
proper servicing intervention.
