Electrical and Gas Requirements

Electrical Requirements
Check your national and local codes regarding this
unit. This range requires 3-wire or 4-wire, 240-208
VAC/60 Hz. (See "Appendix A" for grounding
instructions.) Unit must be fused separately from
any other circuit.
WARNING
ELECTRICAL SHOCK HAZARD. To avoid the
risk of electrical shock, personal injury or death;
verify electrical power is turned off at the
breaker box and gas supply is turned off until
the range is installed and ready to operate,
installation by an authorized installer only.
Gas Connection
The gas supply (service) line must be the same size
or greater than the inlet line of the appliance. This
range uses a 1/2" (1.3 cm) ID NPT (Sch40) inlet.
Sealant on all pipe joints must be resistive to LP
gas.
The range is designed specifically for natural
gas or liquid propane (LP) gas. Before beginning
installation, verify that the model is compatible with
the intended gas supply.
Manual shut-off valve:
This installer-supplied valve must be installed in
the gas service line before the appliance in the gas
stream and in a location where it can be reached
quickly in the event of an emergency.
Connecting Gas & Electric
DANGER
Gas leak hazard. To avoid risk of personal
injury or death; leak testing of the appliance
must be conducted according to the
manufacturer's instructions. Before placing
appliance in operation, always check for gas

the gas supply line to the appliance.
IMPORTANT: Any conversion required must be
performed by your dealer or a qualified licensed
plumber or gas service company. Please provide the
service person with this manual before work begins.
Pressure Regulator:
equipment must have a pressure regulator on
the incoming service line for safe and efficient
operation, since service pressure may fluctuate
with local demand. External regulators are
not required on this range since a regulator
is built into each unit at the factory. Under no
condition bypass this built-in regulator.
manometer, natural gas requires 5.0" W.C.P.
and LP gas requires 10.0" W.C.P. Incoming line
pressure upstream from the regulator must be
1" W.C.P. higher than the manifold pressure
in order to check the regulator. The regulator
used on this range can withstand a maximum
input pressure of 1/2" PSI (14.0" W.C.P.). If the
line pressure is in excess of that amount, a step
down regulator will be required.
gas supply piping system during any pressure
testing of that system.
Flexible Connections:
If the unit is to be installed with flexible couplings
and/or quick-disconnect fittings, the installer must
use a heavy-duty AGA design-certified flexible
connector of at least 1/2" (1.3 cm) ID NPT (with
suitable strain reliefs) in compliance with ANSI
Z21.41 and Z21.69.
In Canada:
CAN 1-6, 10-88 metal connectors for gas
appliances and CAN 1-6.9 M79 quick disconnect
devices for use with gas fuel.
