Regency U28-2/U43-3 ULTIMATE Freestanding Gas Stove
GAS PIPE 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. (3.45
kPa). Disconnect piping from valve at pressures
over 1/2 psig (14" w.c.).
The manifold pressure is controlled by a regulator
built into the gas control, and should be checked
at the pressure test point.
Note: To properly check gas pressure,
both inlet and manifold pressures
should be checked using the valve
pressure ports on the valve.

GAS CONNECTION
The gas line can be rigid pipe, or to make installation easier, use a listed flexible connector if
allowed by local codes. Copper may also be used if approved by local codes.
The gas connection at the valve is 3/8" NPT. For minimum and maximum supply pressure see
the System Data Table.
