Resumen del manual


• The venting system must be installed in a manner which allows inspection of the installation of the venting pipes and joints as well as periodic inspection after installation as required by ANSI Standards. FIGURE 8. AIR FOR VENTILATION FOR APPLIANCES LOCATED IN CONFINED SPACES Air for ventilation should be provided if installed in a confined space. Refer to the National Fuel Gas Code, ANSI Z223.1. FIGURE 9. Horizontal runs must be securely supported at 3 1/2 foot (8.9 cm) intervals and vertical runs supported at 5 foot (1.5 cm) intervals. VENTING THROUGH AN OUTSIDE WALL A. ALL 75 GAL. (283.9L) 65,000 & 70,000 BTU/HR MODELS & 50GAL.(189.3L)60,000 & 65,000 BTU/HR MODELS, SEE FIGURE 10. In the carton is supplied: 1. Two 3" inlet and outlet PVC Schedule 40 - 45° vent caps. 2. A 3" ABS Schedule 40 - 90° street elbow; used to connect the outlet vent pipe to the water heater when the outlet vent pipe is to be turned horizontally directly off the blower. 3. A 5' (1.52 m) section of 3" ABS Schedule 40 outlet vent pipe (more may be required and must be supplied locally). FIGURE 10. HI BTU MODELS. 1. The water heater requires its own (separate) venting system. 2. Only 3" ABS Schedule 40 piping & fittings are acceptablematerials on the first 5' of outlet vent system.This applies to only 50gal. (189.3 L) Hi BTU input models and all 75 gal. (283.9 L) models. 3. 3" PVC, ABS, or CPVC Schedule 40 piping & fittings areacceptable materials for the inlet vent system and for theoutlet vent system after the first 5' (1.52 m). 4. It cannot be connected to existing vent piping or chimney. 5. When venting through an outside wall, the vents mustterminate horizontally to the outdoors. B. ALL 50 GAL.(189.3 L)38,000 AND 40,000 BTU/HRMODELS&40GAL.(151.4 L) 36,000 & 40,000 BTU/HR MODELS, SEE FIGURE 11. In the carton is supplied: 1. Two 3" inlet and outlet PVC Schedule 40 - 45° vent caps. All other piping must be supplied by the supplier. 7 FIGURE 11. STANDARD MODELS. * If making an immediate horizontal run of vent off the blower, two 3" PVC or ABS Schedule 40 street elbows are required. 1. The water heater requires its own (separate) venting system. 2. 3" PVC, ABS or CPVC Schedule 40 piping and fittings are acceptable materials for the vent system. 3. It cannot be connected to existing vent piping or chimney. 4. When venting through an outside wall, the vents must terminate horizontally to the outdoors. VENTING SYSTEM EXAMPLE INSTALLATION FOR ALL MODELS The vent piping cannot under any circumstances be run downhill. FIGURE 12. The vent piping can be installed as follows: 1. Horizontalruns requirea minimum1/8"(3.2mm)riseper 5' (1.52 m). FIGURE 13. FIGURE 14. FIGURE 15. 2. The total vertical and horizontal vent runs cannot exceed the maximum length with the number of 90° elbows as specified in the table below. If more elbows are required, the venting distance must be reduced 5 feet (1.52 m) for every 90° elbows: 3" DIA. VENTS NUMBER OF 90° DEG. MAX. LENGTH (FT.) ELBOWS * 45 (13.72 m) 1 40 (12.2 m) 2 35 (10.7 m) 3 *NOTE: Two 45° elbows are equivalent to one 90° elbow. One 90° elbow equals 5 feet (1.52 m) of equivalent vent length. FIGURE 16. 3. Minimum vent length for all models is 18 inches (45.7 cm). 8 FIGURE 17. FIGURE 17. Cementing PVC, ABS or CPVC Pipe and Fittings Read and observe all safety information printed on printer, cleaner, and cement container. DANGER Primer, cleaner, and cements are extremely flammable. They are harmful or fatal if swallowed. The vapors are harmful. They may irritate eyes and skin and can be absorbed through the skin. PRECAUTIONS Always store primers, cleaner, and cements in cool, dry, well ventilated places. Do not store these near heat, sparks, or flames. Keep container closed. Use them in well ventilated areas. Wear impervious clothing while handling. Do not smoke, eat, or drink while handling. Wash thoroughly after handling and before eating. Wear eye protection when handling. If swallowed, drink water, do not induce vomiting, and call a physician or poison control center immediately. If inhaled, get fresh air and seek medical attention if ill feelings persist. In case of eye and skin contact, immediately flush with plenty of water for 15 minutes and seek medical attention if irritation persists. KEEP OUT OF REACH OF CHILDREN. All primers, cleaners and cements must meet all local codes and applicable standard of the American Society For Testing Materials Standards. Before using primers, cleaners, and cements, stir or shake, making sure contents are liquid. Do not use if found to be lumpy or jelly-like. 1. Cut pipe ends squarely, removing all burrs and dirt. 2. Dry fit pipe and fittings to be connected for proper fit. 3. Clean pipe and fitting with a primer/cleaner. 4. Apply a thin coat of cement to fitting, avoiding puddling inside. 5. Apply a liberal coat of cement to pipe, leaving no voids. 6. QUICKLY assemble parts while cement is fluid! If you wait too long, re-coat pipes. 7. Push pipe completely i...
