The relief pressure marked on the relief valve must not exceed that stated on the rating plate of the water heater. IMPORTANT: The relief valve must be connected to a discharge or drain pipe no smaller in size than the outlet of the relief valve. This pipe must not be valved, plugged, allowed to freeze, or be restricted in any way. Terminate close to a drain of adequate capacity. The relief valve is necessary to avoid excessive water pressure or water temperature from developing. Such a condition could cause serious personal injury due to scalding or serious physical damage to the water heater. This safety device shall be checked annually for proper operation. Check local Codes. 6. With water piping installed, check that a hot water faucet served by the water heater is open and that the heater drain valve is closed. Open the cold water supply valve and fill the water heater and piping system with water. When an uninterrupted stream of water flows from the faucet, the system is full. Close faucet. Check for leaks and repair as necessary. 7. Connect a hose to the drain valve and connect to drain. Open drain and let water run until clear to flush out any foreign matter that may have entered the system. Once flushed, close the drain valve and disconnect hose. V) Gas Service Gas piping and fitting shall be installed as shown in Figure 9. Check that a properly sized gas meter and regulator are available to service the water heater. If other appliances are using the same meter and regulator, ensure that the capacity of the meter and regulator matches that of the combined input of all appliances connected to it. The gas control supplied with this water heater is designed for a maximum inlet pressure of 0.5 p.s.i. (14" water column). -8 WARNING Exposure to a higher gas supply pressure may cause damage to the control, resulting in explosion or fire. Consult your local gas supplier and gas authorities. DO NOT PUT INTO SERVICE IF OVER-PRESSURIZATION HAS OCCURRED. Use gas piping of adequate sizing to ensure full gas input. All piping must comply with all local codes. In the absence of local codes, piping must comply with the rules stated by the applicable National Fuel Gas Codes. Final connection to the water heater is made using 1/2" N.P.T. pipe. • A manual gas shut-off valve shall be installed in the gas line near the water heater. A union is recommended for ease of service. • To trap dirt or foreign material in the gas supply, a dirt (drip) leg shall be installed in the piping. • Apply joint compound (pipe dope) to the male ends of the threads before joining pipe sections. Use only compounds that are compatible with natural gas and propane fuels. To prevent damage to the gas valve, do not over-tighten. Purging Caution: Gas line purging is required to eliminate air from the piping system. Purging should be performed by persons experienced in this type of gas service. Do not purge in confined areas or space where ignition may occur. To avoid risk of fire or explosion ensure the area is well-ventilated and all sources of ignition are deactivated. Contact your local gas authority for local requirements. IMPORTANT: Disconnect the water heater from the gas piping during any high pressure testing above 0.5 p.s.i. Perform a leak test at normal gas pressure on all fittings after all connections have been made and the gas has been turned on. Soap test all connections of the gas system - bubbles indicate leaks. Gas Pressure GSW Water Heating Company recommends that the gas supply pressure as measured on the inlet side of the water heater control, be set at 7.0 inches water column for natural gas and 11.0 inches water column for propane gas. Electrical Supply A three-wire cord and plug is provided with this water heater. The plug shall be connected into an electrically grounded, 120 VAC, 60 Hz, 12 Amps, fused receptacle. The electrical supply must meet the minimum provisions as stated in the National Electrical Code for U.S. customers and in the Canadian Electrical Code for Canadian customers. The electrical controls used inside the thermostat/gas valve mounted on this water heater is polarity sensitive. Ensure that the electrical supply is properly connected in the receptacle box. Failure to connect properly will cause the unit not to function (See Figure 10). -11 Important: in locations where a sump pump failure, flooding or exposure to water may be present, a ground fault receptacle is recommended. VI) Lighting and Operating Instructions WARNING READ BEFORE PROCEEDING If you do not understand and follow these instructions, a fire or explosion may result. This SuperflueO Water Heater is equipped with an electric combination thermostat / gas valve control and an ignition device that lights the burner. DO NOT ATTEMPT TO LIGHT THIS WATER HEATER MANUALLY! The control contains internal self-diagnostic features and an external LED monitor light (Figure 11). During operation a flashing LED indicates a burner or ignitor failure, putti...
