Pressure Testing - JENN-AIR JGC8430 Manual De Instalación

ALTERNATIVE PIPING METHODS TO CONNECT
APPLIANCE TO GAS SUPPLY
A TRAINED SERVICEMAN OR GAS APPLIANCE INSTALLER MUST
MAKE THE GAS SUPPLY CONNECTION. Leak testing of the appliance
shall be conducted by the installer according to the instructions
given.
Unless prohibited by local codes or ordinances, a new A.G.A. - - Certified,
flexible metal appliance connector may be used to connect this appliance
to its gas supply. The connector must have an internal diameter not less
than nominal 1/2² NPT pipe and be no more than 5 feet in length. A 1/2²
NPT x 1/2² flare union adapter is required at each end of the flexible
connector. If a flexible connector is used assure that both the appliance
pressure regulator and manual shut-off valve are joined solidly to other
permanent hard piping (either gas supply or the appliance manifold) so as
to be physically stationary. See illustrations below:

Do not attempt to attach the flexible connector directly to
an external pipe thread. Connection requires flare union
adapters.
Apply a non-corrosive leak detection fluid to all joints and fittings in the
gas connection between the supply line shut-off valve and the range.
Include gas fittings and joints in the range if connections were disturbed
during installation. Check for leaks! Bubbles appearing around fittings
and connections will indicate a leak. If a leak appears, turn off supply line
gas shut-off valve, tighten connections, turn on the supply line gas shut
off valve, and retest for leaks. Never test for gas leaks with an open
flame.

PRESSURE TESTING

The appliance must be isolated from the gas supply piping system by
closing its individual manual shut-off valve during any pressure testing of
the gas supply piping system at test pressures equal to or less than 1/2
PSIG (3.5 kPa).
This appliance, as well as its individual shut-off valve, must be
disconnected from the gas supply piping system during any pressure
testing of the system at test pressures in excess of 1/2 PSIG (3.5 kPa).
When checking appliance regulator function, make certain pressure of
natural gas supply is between 6 and 14 inches of water column or, if
converted for LP gas, between 11 and 14 inches.
