Do not block access to the shutoff valve. The valve is for turning on or shutting off gas to the appliance. Shutoff valve “open” position Gas supply line To range 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. Fig. 2.1 2. Pressure Regulator: a) 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 1/2” NPT (conical) male connector to the regulator (see picture 2.2a). Gasket supplied have to be placed between 1/2” NPT (conical) connector/extension pipe male pipe fitting (see picture 2.2b). The regulator supplied with this range must be installed before any gas connections are made. Use supplied pressure regulator only. 14 PRESSURE REGULATOR INSTALLATION LOCK Arrow STEP 1 Mount the 1/2” 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 2 Assemble the 1/2” NPT connector + pressure regulator group to the extension pipe interposing the gasket supplied. The regulator cover must be oriented toward the front side of the range. IMPORTANT: use two spanners to tighten the connection.

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. b) 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 is started on the range. (Gas conversions are the responsibility of the dealer or end user.) c) This range can be used with NATURAL or LP/PROPANE gas. It is shipped from the factory adjusted for use with NATURAL gas. d) Manifold pressure should be checked with a manometer and by operating as below detailed: - Remove the injector from the front left burner and mount the proper test point adapter which is available from the After-Sales Service (see side figure and the “OPERATIONS TO BE PERFORMED WHEN SUBSTITUTING THE INJECTORS” chapter). - Turn the front left burner control knob to the maximum position ( position) - Press the knob and keeping it pressed check the manifold pressure with a manometer; NATURAL gas requires 4.0” W.C.P. and LP/PROPANE requires 11.0” 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 stepdown regulator will be required. e) 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). f) 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). 3. Flexible Connections: If local codes permit, CSA design-certified, flexible metal appliance connector is recommended for connecting this range to the gas supply line. Do Not kink or damage the flexible connector when moving the range. The pressure regulator has 1/2" 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.
