Table 6: Schedule 40 Black Iron Pipe— Inside Diameter PROPER SIZING OF GAS LINE Properly size and route the gas supply line from the supply regulator to the area where the appliance is to be installed per requirements outlined in the National Fuel Gas Code, ANSI Z223.1 (NFPA 54)—latest edition (USA) or CAN/CGA-B149.1—latest edition (Canada). STEP 2. ROUTING GAS LINE Route a 1/2" (13 mm) gas line as shown in Figure 11. Gas lines must be routed, constructed and made of materials that are in strict accordance with local codes and regulations. The appliance, as set up at the factory, is best suited for use with a gas line routed from the left side. The gas line may however be alternately routed from the right side. All appliances are factory-equipped with a fl exible gas line connector and 1/2 inch shutoff valve. (See Step 6 on Page 12). Never use galvanized or plastic pipe. Refer to Table 6 for proper sizing of the gas supply line, if black iron pipe is being used. Gas lines must be routed, constructed and made of materials that are in strict accordance with local codes and regulations. We recommend that a qualifi ed individual such as a plumber or gas fi tter be hired to correctly size and route the gas supply line to the appliance. Installing a gas supply line from the fuel supply to the appliance involves numerous considerations of materials, protection, sizing, locations, controls, pressure, sediment, and more. Certainly no one unfamiliar and unqualifi ed should attempt sizing or installing gas piping. Notes: • All appliances are factory-equipped with a fl exible gas line connector and 1/2 inch shutoff valve (see Figure 46 on Page 25). Also see Figure 12. Figure 11: Route Gas Line 3" (76 mm) 6-1/2" (152 mm) Pipe Coupling (Recommended) • See Massachusetts Requirements on Page 4 for additional requirements forinstallations in the state of Massachusetts in the USA. • The gas supply line SHOULD NOT beconnected to the appliance until Step 6 on Page 12). • A pipe joint compound rated for gasshould be used on the threaded joints. Ensure propane resistant compounds areused in propane applications. Be verycareful that the pipe compound does notget inside the pipe. • It is recommended to install a sediment trap in the suppl...
