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 eﬃ 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-oﬀ 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-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” 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.
