Countertop Preparation - Whirlpool GW397LXUS Installation Instructions Manual

Gas Supply Line
Provide a gas supply line of ¾" (1.9 cm) rigid pipe to the range
location. A smaller size pipe on longer runs may result in
insufficient gas supply. Pipe-joint compounds that resist the
action of LP gas must be used. Do not use TEFLON
With LP gas, piping or tubing size can be ½" (1.3 cm)
minimum. Usually, LP gas suppliers determine the size and
materials used in the system.
Flexible metal appliance connector:
If local codes permit, a new CSA design-certified,
4 to 5 ft (122 to 152.4 cm) long, ½" (1.3 cm) or
¾" (1.9 cm) I.D., flexible metal appliance connector may
be used for connecting range to the gas supply line.
A ½" (1.3 cm) 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.
Rigid pipe connection:
The rigid pipe connection requires a combination of pipe
fittings to obtain an in-line connection to the range. The rigid
pipe must be level with the range connection. All strains must
be removed from the supply and fuel lines so range will be
level and in line.
Must include a shutoff valve:
The supply line must be equipped with a manual shutoff valve.
This valve should be located in the same room but external to
the range. It should be in a location that allows ease of
opening and closing. Do not block access to shutoff valve.
The valve is for turning on or shutting off gas to the range.

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: 5" WCP
Maximum pressure: 14" WCP
LP gas:
Minimum pressure: 11" WCP
Maximum pressure: 14" 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
1" water column pressure above the manifold pressure shown on
the model/serial rating plate.
Line pressure testing above ½ psi gauge (14" WCP)
The range and its individual shutoff valve must be disconnected
from the gas supply piping system during any pressure testing of
that system at test pressures in excess of ½ psi (3.5 kPa).
Line pressure testing at ½ psi gauge (14" WCP) or lower
The range must be isolated from the gas supply piping system by
closing its individual manual shutoff valve during any pressure
testing of the gas supply piping system at test pressures equal to
or less than ½ psi (3.5 kPa).

Countertop Preparation

(for Slide-in Ranges Only)
The cooktop sides of the slide-in range fit over the cutout edge of
your countertop.
If you have a square finish (flat) countertop and the opening width
is 30" (76.2 cm), no countertop preparation is required.
Formed front-edged countertops must have molded edge shaved
flat ³⁄₈" (1.0 cm) from each front corner of opening.
Tile countertops may need trim cut back ³⁄₈" (1.0 cm) from each
front corner and/or rounded edge flattened.
30"
(76.2 cm)
If countertop opening width is greater than 30" (76.2 cm), adjust
the ³⁄₈" (1.0 cm) dimension.
Countertop must be level. Place level on countertop, first side to
side, then front to back. If countertop is not level, range will not be
level. Range must be level for satisfactory baking conditions.
