Electrical & 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

“Electrical Connection” section for

grounding instructions. Must be fused seperately from any other circuit.

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:

• All heavy-duty, commercial type cooking

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.

In Massachusetts: This appliance must be installed with a 36” (3-foot) long flexible gas connector.

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

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

2-3/4”

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.

	the factory. Under no condition bypass
	this built-in regulator.
•	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 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.
•	The appliance must be disconnected from
	the gas supply piping system during any
	pressure testing of that system.

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.

In Massachusetts: A “T” handle type manual valve must be installed in the gas supply line to the appliance.
