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 / " (1.3 cm) ID NPT (Sch40) inlet. Sealant on all
1
2
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. Any opening behind the range shall be
sealed.
Connecting Gas & Electric
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 leaks with soapy water solution.
DO NOT USE AN OPEN FLAME TO CHECK FOR
GAS LEAKS.

General Information

Pressure Regulator

• All heavy-duty, commercial type cooking 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.
• The appliance must be disconnected from the gas
supply piping system during any pressure testing of
that system.
• Manifold pressure should be checked with a
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
(14.0" W.C.P.). If the line pressure is in excess of that
amount, a step down regulator will be required.

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 / " (1.3 cm) ID NPT (with suitable strain reliefs) in
1
2
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.
In Massachusetts
This appliance must be installed with a 36" (3-foot) long
flexible gas connector.

Performance Checklist

A qualified installer should carry out the following checks:
• Check top burner ignition. See drawing for proper
flame height on HI. The low flame should light at every
port.
1-1/2"
(3.8 cm)
• Check oven bake function—bake burner on full power.
• Check oven broil function—broil burner on full power.
• Check convection fan function—convection fan comes
on when switch is turned on.
