Resumen del manual
Contact your gas supplier for any specific changes which may be required in your area. Use pipe joint compound or teflon tape marked as being resistant to the action of petroleum [Propane (L.P.)] gases. The appliance and its gas connection must be leak tested before placing the appliance in operation. The appliance and its individual Shut-off valve shall be disconnected from the gas supply piping system during any pressure testing of that system at test pressures in excess of 1/2 pound per square inch (3.5 kPa). It shall be isolated from the gas supply piping system by closing its individual manual Shut-off valve during any pressure testing of the gas supply piping system at test pressures equal to or less than 1/2 pound per square inch (3.5 kPa). Connecting the gas piping to the gas control valve of the water heater can be accomplished by either of the two methods shown in Figures 12 and 13. FIGURE 12. GAS PIPING WITHFLEXIBLE CONNECTOR. FIGURE 13. GAS PIPING WITH ALLBLACK IRON PIPE TO GAS CONTROL. 14 SEDIMENT TRAPS A sediment trap shall be installed as close to the inlet of the water heater as practical at the time of water heater installation. The sediment trap shall be either a tee fitting with a capped nipple in the bottom outlet or other device recognized as an effective sediment trap. If a tee fitting is used, it shall be installed in conformance with one of the methods of installation shown in Figures 12 and 13. Contaminants in the gas lines may cause improper operation of the gas control valve that may result in fire or explosion. Before attaching the gas line be sure that all gas pipe is clean on the inside. To trap any dirt or foreign material in the gas supply line, a drip leg (sometimes called a sediment trap) must be incorporated in the piping. The drip leg must be readily accessible. Install in accordance with the “Gas Piping” section. Refer to the current edition of the National Fuel Gas Code (ANSI Z223.1/NFPA 54) or the Natural Gas and Propane Installation Code (CAN/CSA B149.1). FIGURE 14. FILLING THE WATER HEATER Never use this water heater unless it is completely full of water. To prevent damage to the tank, the tank must be filled with water.Water must flow from the hot water faucet before turning “ON” gas to the water heater. To fill the water heater with water: 1. Close the water heater drain valve by turning the handle to the right (clockwise). The drain valve is on the lower front of the water heater. 2. Open the cold water supply valve to the water heater. NOTE: The cold water supply valve must be left open whenthe water heater is in use. 3. To insure complete filling of the tank, allow air to exit by opening the nearest hot water faucet. Allow water to run until a constant flow is obtained. This will let air out of the water heater and the piping. 4. Check all water piping and connections for leaks. Repair as needed. VENT PIPE ASSEMBLY There are three parts of the vent pipe assembly that connect the water heater exhaust (located on the lower back side of the water heater) to the inlet of the blower assembly (mounted on top of the water heater) as shown in Figure 1. These parts will need to be assembled according to the instructions in the VENT PIPE PREPARATION section of this manual. These PVC parts should be assembled with ASTM D-2564 grade cement. Assemble Vent Pipe Assemblies #1, #2 and #3 (See Figure 1) prior to cementing. The preferred orientation of Vent Pipe Assembly #1 (Condensate U-Assembly) is shown in Figure 16. However this assembly may be rotated to a different orientation as needed for the specific installation requirements. Note the rotational orientation of each part by marking a line several inches long across the joints.The long tube of Vent Pipe Assembly #2 should be approximately vertical. If it is found that either of the two pieces of pipe in Vent Pipe Assembly #2 are too long for proper fit-up, then remove as little material as possible to improve the fit-up. Keep in mind that the pipes will insert slightly further into the elbows when cement is applied as it acts as a lubricating agent. The vertical distance from the bottom of the Condensate U-Assembly to the floor that supports the water heater should be approximately 0.25" (0.64 cm), see Figure 16. Disassemble the parts and cement back together using the alignment marks. After the cement dries, attach the assembly to the blower and the water heater exhaust using the supplied rubber boots and hose clamps. A condensate trap is incorporated in the bottom of this vent pipe assembly. See the CONDENSATE section of this manual for further details.
