Gas Connection

All gas connections must be made according to national and local codes. This gas supply (service) line must be the same size or greater than the inlet line of the appliance. Sealant on all pipe joints must be resistant to the action of LP/Propane gas.
The cooktop is equipped for the use with NATURAL gas. It is design-certified by CSA International for NATURAL and L.P. gases with appropriate conversion.
The model/serial rating plate, located on the underside of the burner box, has information on the type of gas that can be used. If this information does not agree with the type of gas available, check with the local gas supplier. See page from 14 to 15 for L.P. gas conversion instructions.

Manual Shut-off Valve (fig: 2.1):
A manual shut-off valve must be installed in an accessible location in the gas line external to the appliance for the purpose of turning on or shutting off gas to the appliance (In Massachusetts such shutoff devices should be approved by the Board of State Examiners of Plumbers & Gas Fitters).
This valve should be located in the same room as the cooktop and should be in a location that allows ease of opening and closing (in a position where it can be reached quickly in the event of an emergency).
Do not block access to the shutoff valve. The valve is for turning on or shutting off gas to the appliance.

WARNING: Explosion Hazard

• Use a new CSA or UL approved gas supply line.
• Install a shut-off valve.
• Securely tighten all gas connections.
• If connected to LP, have a qualified person make sure gas pressure does not exceed 14″ water column.
• Examples of a qualified person include licensed heating personnel, authorized gas company personnel, and authorized service personnel.
• Failure to do so can result in death, explosion, or fire.

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.
Before installing the regulator mount the 3/8” NPT (conical) male connector to the regulator (see picture 2.2c).
Gasket supplied has to be placed between 3/8” NPT (conical) connector/extension pipe male pipe fitting (see picture 2.2d).
The regulator supplied with this cooktop must be installed before any gas connections are made.
Use supplied pressure regulator only.

PRESSURE REGULATOR INSTALLATION

STEP 1: The elbow connection can be turned in the direction required after the manifold female pipe fitting has been slackened by using a wrench.

Then tighten the elbow-manifold female pipe fitting connection by using a wrench before proceeding with gas connection.

When tightening keep the elbow connection firm i.e. by using an adjustable pliers or an adjustable wrench (pay attention not to damage the thread).

STEP 2: Mount the extension pipe to the elbow connection interposing the gasket supplied and tighten by using a wrench.
When tightening keep the elbow connection firm i.e. by using an adjustable pliers or an adjustable wrench (pay attention not to damage the thread).

STEP 3: Mount the 3/8” NPT (conical) male connector to the pressure regulator and tighten by using a wrench.
Do not over tighten the connector.
Over tightening may crack regulator.

STEP 4 Assemble the 3/8” NPT connector + pressure regulator group to the extension pipe interposing the gasket supplied.
IMPORTANT: use two spanners to tighten the connection.

GAS CONNECTION SPECIFICATION

• Any conversion required must be performed by your dealer or a qualified licensed technician or gas service company. Please provide the service person with this manual before work is started on the cooktop. (Gas conversions are the responsibility of the dealer or end user.)
• This cooktop can be used with NATURAL or LP/PROPANE gas. It is shipped from the factory adjusted for use with NATURAL gas.
• Manifold pressure should be checked with a manometer; NATURAL gas requires 4.0” W.C.P. and LP/PROPANE requires 11.0” W.C.P. (see figure below).
  • 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 cooktop 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, its individual shut-off valve, and pressure regulator must be disconnected from the gas supply piping system during any pressure testing of that system at pressures in excess of 1/2 PSI (3.5 kPa).
• The appliance must be isolated from the gas supply piping system by closing its individual manual shut-off valve during any pressure testing of the gas supply piping system at test pressure equal to or less than 1/2 PSI (3.5 kPa).

Flexible Connections:
If local codes permit, CSA or UL design-certified, flexible metal appliance connector is recommended for connecting this cooktop to the gas supply line. Do Not kink or damage the flexible connector when moving the cooktop. The pressure regulator has 3/8” NPT female pipe threads. You will need to determine the fittings required, depending on the size of your gas supply line, flexible metal connector and shutoff valve.

Rigid Pipe Connections:
If rigid pipe is used as a gas supply line, a combination of pipe fittings must be used to obtain an in-line connection to the cooktop. All strains must be removed from the supply and fuel lines so cooktop will be level and in line.

• Use joint compounds and gaskets that are resistant to action of natural or propane gas on all male pipe threads.
• Do not over tighten gas fitting when attaching to pressure regulator. Over tightening may crack regulator.

Leak Testing:
IMPORTANT: Leak testing of the appliance shall be conducted as follows:

• After final gas connection is made, turn on manual gas valve and test all connections in gas supply piping and appliance for gas leaks with a soapy water solution. During this test all appliance gas valves have to be closed.
• In order to avoid property damage or serious personal injury, never use a Iighted match. If a leak is present, tighten joint or unscrew, apply more joint compound, tighten again and retest connection for leak.

CONVERSION TO LP/PROPANE GAS (OR CONVERSION BACK TO THE ORIGINAL GAS – NATURAL GAS)
Every cooktop is provided with a set of injectors for the various types of gas.
Select the injectors to be replaced according to the “INJECTORS TABLE”.
The nozzle diameters, expressed in hundredths of a millimetre, are marked on the body of each injector.

CAUTION: Save the orifices removed from the appliance for future use.
