Gas Supply Installation

Figure 3
When shipped from the factory, this unit is designed
to operate on 4" water column (1.0 kPa) Natural gas
manifold pressure. A convertible pressure regulator
is connected to the range manifold and MUST be
connected in series with the gas supply line. To access
the regulator, remove the drawer.
For proper operation, the maximum inlet pressure
to the regulator should be no more than 14" of water
column pressure (3.5 kPa).
The inlet pressure to the regulator must be at least 1"
(.25 kPa) greater than the regulator manifold pressure
setting. The regulator is set for 4" water column (1.0
kPa) Natural gas manifold pressure; the inlet pressure
must be at least 5" water column (1.25 kPa) Natural
gas. For LP/Propane gas, the regulator must be set for
10" water column (2.5 kPa) manifold pressure; the inlet
pressure must be at least 11" water column (2.75 kPa).
The supply line should be equipped with an approved
shutoff valve (see Figure 3). This valve should be located
in the same room as the range and should be in a
location that allows ease of opening and closing. Do not
block access to the shutoff valve. The valve is for turning
ON or shutting OFF gas to the appliance. Open the
shutoff valve in the gas supply line. Wait a few minutes
for gas to move through the gas line.
The gas supply between the shutoff valve and the
regulator may be connected by rigid piping or by C.S.A.
approved flexible metallic union connected piping where
local codes permit use.
The gas supply piping can be through the side wall
of the right cabinet. The right side cabinet is an ideal
location for the main shutoff valve.
(Models with Electric Ovens and Gas Cooktop)
Do not make the connection too tight.
The regulator is die cast. Overtightening may crack the
regulator resulting in a gas leak and possible fire or
Assemble the flexible conduit from the gas supply pipe
to the pressure regulator in this order:
1- manual shutoff valve, 2- flare union adapter,
3- flexible conduit, 4- flare union adapter,
5- pressure regulator.
The gas supply line to the shutoff valve should be
1/2" or 3/4" solid pipe.
The user must know the location of the main shutoff
valve and have easy access to it.
When using flexible gas conduit on the range, allow
sufficient slack to pull the range outside the cutout for
cleaning or servicing.
NOTE: Do not allow the flexible conduit to get pinched
between the wall and the range. To visually check,
remove the range drawer.
Use pipe-joint compound made for use with Natural and
LP/Propane gas to seal all gas connections. If flexible
conduit is used, be certain that it is not kinked.
Leak testing of the appliance shall be conducted
according to the manufacturer's instructions.
Check for leaks. After connecting the range to the gas
supply, check the system for leaks with a manometer. If
a manometer is not available, turn on the gas supply and
use a liquid leak detector at all joints and connections to
check for leaks.
Do not use a flame to check for leaks
from gas connections. Checking for leaks with a flame
may result in a fire or explosion.
All openings in the wall or floor where the range is to be
installed must be sealed.
Tighten all connections if necessary to prevent gas
leakage in the cooktop or supply line.
Check alignment of valves after connecting the
cooktop to the gas supply to be sure the manifold pipe
has not been moved.
Disconnect the range and its individual shutoff
valve from the gas supply piping system during any
pressure testing of the system at test pressures greater
than 1/2 psig (3.5 kPa or 14" water column).
