HOLD INLET BUSHING OR NIPPLE WHEN TIGHTENING FITTINGS. ROTATING BUSHING COULD DRASTI- CALLY REDUCE PERFORMANCE. INLET BUSHING INDEX MARK Connect the water piping, being careful not to apply heat to the heater nipples. Install dielectric unions and shut off valves on both hot and cold water lines. The 40E and all “C” models (example: 32EC, 51PPC) have a 1” NPT tapping located on the front left side of the tank. This is an alternate outlet for use with combined appliance applications. If this fitting is not used, plug it with a fitting suitable for potable water. A 1” NPT fitting is also located behind the drain valve on the 40E and all “C” models. This is for use as an alternate inlet or a combined appliance return. Your heater is shipped with a reducer in this location to mount the drain valve. The 33E and 40E models are equipped with a brass inlet bushing installed in the tank. Heaters equipped with this bushing are marked next to the inlet by the decal shown on the left. The purpose of this bushing is to help keep the tank bottom free of sediment by aiding tank flushing. This bushing must be located as shown on the decal to function properly. Do not allow the bushing to rotate out of position when tightening the inlet fittings. In installations requiring high flow rates, contact the factory. The drain valve fitting may be used as an alternate cold water inlet on heaters equipped with a dip tube, as shown in Figure 3. By plumbing a “T” into the drain fitting, the cold water inlet can be relocated to this point. The dip tube must be removed and its fitting plugged. Figure 3 also shows a copper loop heat trap installed on the hot water outlet to reduce standby losses. Note: When converting to this configuration on an existing heater, visually inspect the heater and make certain it does not have scale buildup on the bottom of the tank. Scale can restrict the flow of water into the tank. CAUTION!! Scalding injury and/or water damage can occur from either the manual lifting of the lever or the normal operation of the T&P valve if it is not piped to a proper drain. If the valve fails to flow water or reseat, call a plumber. FIGURE 3 – 4 – CONNECT THE OIL LINE WARNING!! WHEN YOU INSTALL THE BYPASS PLUG YOU MUST RUN A TWO-LINE SYSTEM.

CONNECT THE ELECTRICITY MOUNT THE OIL BURNER CONNECT TO CHIMNEY Inspect the incoming water line for check valves or water pressure reducing valves. Any type of check valve may cause pressure to build up in the heater and cause tank failure. If the heater is installed in a closed system or if backflow pre- venters and pressure regulators are installed, add an expansion tank. Do not try to heat hard water. Install a water softener if the heater is being used in a hard water area (water hardness more than 7 grains). An approved temperature and pressure (T&P) reli...
