POTENTIAL PROBLEMS ...continued REPLACE any damaged supply lines. • Check the Regulator Make sure that the regulator & hose assembly is the one designed for and supplied with your grill and that it is correctly set up for the type of fuel you are using. (See INDEX: "Regulator Conversion" for further details.) The hose and regulator provided must be used if your grill is setup for an LP Gas Cylinder. Check that there is no physical pressure being applied to the regulator attached to the back of the grill. The regulator contains a flexible diaphragm and should not be allowed to touch the grill body or its surroundings. • Check for Obstructions Ensure that the burners and drip tray are clean and free from obstructions. LP (Propane) units: • Is the cylinder almost empty? Natural gas inlet pressure should be at least 5" W.C. and manifold pressure not less than 4" W.C. under full load (with all burners on.) • Check burners for blockages. • Check flame characteristics. (See INDEX: "Flame, Correct Size" ) • Clean or adjust air shutter (See INDEX: "Air Shutter Adjustment." WIND HITTING GRILL Wind hitting the grill while in use, especially winds blowing into or across the hood gap from behind, can cause poor performance and in some cases can cause the control panel to get dangerously hot. Steady or gusty winds can prevent the normal exhaust of hot gases. Locate your grill away from prevailing winds and avoid grilling in windy conditions. Almost-empty cylinders may not have sufficient pressure to run the burners at high heat. • Have the line pressure checked by a qualified technician (See INDEX: "Gas Requirements" for further details.) • Flow Limiting Device Improper lighting procedures may have activated the LP cylinder's flow control device, reducing the heat output. To reset the flow control: • Shut off all burner controls and close the LP cylinder valve. • Wait 30 seconds and, very slowly, reopen the cylinder valve. • Wait a few seconds and relite a burner. Bulk LP cylinder users: Bulk LP cylinder lines must be properly regulated. Ensure that you are using a 4/11 appliance regulator supplied by Viking Range, LLC and converted to LP gas. Also ensure that you do not have more than one regulator in line. Natural Gas units: • Supply Line Ensure that the supply line is at least 3/4" inside diameter or 1" outside diameter. • Check line pressure | 36 INSTALLATION / USE & CARE
