GAS CONNECTION
Natural gas 4.0" iwc
LP/Propane 10.0" iwc.
Incoming line pressure upstream from the regulator must
be 1" iwc 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" 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 system 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
disconnect the appliance from gas and
electric supply and extra appliance from
final installation place in order to have
access to the appliance for proper servicing
intervention.
