D. Gas Pressure
Proper input pressures are required for optimum appliance performance. Gas line sizing requirements need to be made following NFPA51.
WARNING
Fire Risk
Explosion Risk
High pressure will damage valve.
•Disconnect gas supply piping BEFORE pressure testing gas line at test pressures above 1/2 psig.
•Close the manual shutoff valve BEFORE pressure testing gas line at test pressures equal to or less than 1/2 psig.
WARNING
CHECK FOR GAS LEAKS
Fire Risk
Explosion Risk
Asphyxiation Risk
•Check all fittings and connections.
•Do not use open flame.
•After the gas line installation is complete, all connections must be tightened and checked for leaks with a commercially available,
Fittings and connections may have loosened during shipping and handling.
WARNING
Fire Risk
Explosion Risk
Do NOT change the valve settings.
•This valve has been preset at the factory.
•Changing valve settings may result in fire hazard or bodily injury.
•Gas Supply Pressure: Minimum inlet gas supply pressure must be 4.5 in. W.C. for natural gas or 11 in. W.C. for LP gas for the purpose of input adjustment. Maximum inlet gas pressure must not exceed 7.0 in. W.C. for natural gas or 13 in. W.C. for LP gas. The gas line supplying the appliance must be sufficient size to furnish the appropriate supply pressure to the appliance while operating in the “High” setting. (Minimum line ID of 1/2 in. required if the line is longer than 20 ft.
•Gas Line Pressure Test: Perform pressure test according to state and local code (if pressure exceeds 1/2 in. psi [3.5 kPa]) before appliance is connected. Be sure to release air pressure from the gas line before connection is made to the appliance. Excessive pressure will damage the gas control and may cause a gas leak.
•Gas Leak Test: Make sure the gas connections are tight. Turn on the gas and coat each joint with a
