Whirlpool WEGA25H0HZ Installation Instructions Manual page 8

Flexible Metal Appliance Connector:
If local codes permit, a new CSA design-certified, 4 to 5 ft
■
(122 to 152.4 cm) long, 1/2" or 3/4" (13 or 19 mm) I.D. (inside
diameter), flexible metal appliance connector may be used
for connecting range to the gas supply line.
A 1/2" (13 mm) male pipe thread is needed for connection to
■
the female pipe threads of the inlet to the appliance pressure
regulator.
Do not kink or damage the flexible metal tubing when
■
moving the range.
Must include a shut-off valve:
■
Install a manual gas line shut-off valve in an easily accessible
location. Do not block access to shut-off valve. The valve is
for turning on or shutting off gas to the cooktop.

Gas Pressure Regulator
The gas pressure regulator supplied with this range must be
used. The inlet pressure to the regulator should be as follows for
proper operation:
Natural Gas:
Minimum pressure: 15.2 cm WCP
Maximum pressure: 35.6 cm WCP
Propane Gas:
Minimum pressure: 27.9 cm WCP
Maximum pressure: 35.6 cm WCP
Contact local gas supplier if you are not sure about the inlet
pressure.
Burner Input Requirements
Input ratings shown on the model/serial/rating plate are for
elevations up to 2,000 ft (609.6 m).
For elevations above 2,000 ft (609.6 m), ratings are reduced at
a rate of 4% for each 1,000 ft (304.8 m) above sea level (not
applicable for Canada).
Gas Supply Pressure Testing
Gas supply pressure for testing regulator must be at least
2.5 cm water column pressure above the manifold pressure
shown on the model/serial/rating plate.
Line Pressure Testing Above 1/2 psi (3.5 kPa) Gauge
14" (35.6 cm WCP)
The range and its individual shut-off valve must be disconnected
from the gas supply piping system during any pressure testing of
that system at test pressures in excess of 1/2 psi (3.5 kPa).
Line Pressure Testing at 1/2 psi (3.5 kPa) Gauge
14" (35.6 cm WCP) or Lower
The range 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 psi (3.5 kPa).
