Resumen del manual


Insulation on outside runs of exhaust pipe must be painted or wrapped to protect insulation from deterioration. NOTE -During extremely cold temperatures, below approximately 20°F (6.67°C), units with long runs of vent pipe through unconditioned space, even when insulated, may form ice in the exhaust termination that prevents the unit from operating properly. Longer run times of at least 5 minutes will alleviate most icing problems. Also, a heating cable may be installed on exhaust piping and termination to prevent freeze-ups. Heating cable installation kit is available from Lennox. See Condensate Piping section for part numbers. NOTE -Care must be taken to avoid recirculation of exhaust back into intake pipe. 6 -On field-supplied terminations for side wall exits, exhaust piping should extend a maximum of 12 inches (305 mm) beyond the outside wall. Intake piping should be as short as possible. See figure 10. IMAX.

Venting FIGURE 10 7 On field-supplied terminations, a minimum separation distance between the end of the exhaust pipe and the end of the intake pipe is 8 inches (203 mm). 8-If intake and exhaust piping must be run up a side wall to position above snow accumulation or other obstructions, the piping must be supported every 3 feet (.91 m) as shown in figure 15. Refer to figures 13 and 14 for proper piping method. W'FK wall termination kit must be extended for use in this application, See figure 18 or use kit WTKX shown in figure 19. When exhaust and intake piping must be run up an outside wall, the exhaust piping is reduced to 1-1/2 inches (38 mm) after the final elbow. The intake pipingmaybeequippedwitha90° elbowturndown. Using 90° turndown will add 5 feet (1.5 m) to the equivalent length of the pipe. 1/2 (13) ARMAFLEX INSULATION IN UNCONDITIONED SPACE 1/2 (13) ARMAFLEX INSULATION OUTSIDE j WALL Inches (ram) Inches (mm) EXHAUST INTAKE CONCENTRIC ROOFTOP TERMINATION (60G77) LB-49107CE for G32-75 Units Only (33K97) LB-87942 for G32-100 & -125 Units Only FIGURE 9 12 (305) MIN. 2 X 1-1/2 (51 X 38) PV REDUCER _ _ 'VC t' I 6 (I 52) MAXIMUM _ 2 (_ I PVC PLING TOPVIEW Page 11 1/2 (12.7) FOAM INSULATION IN UNCONDITIONED SPACE Inches (mm) n OUTSIDEWALL qlp Optional Turndown Shown (Intake Onty) TOPVIEW WALLTERMINATION (22G44)LB-49107CDfor2 (50,8)Venting (44J40)LB-65701Afor 3 (76.2)Venting FIGURE 11 EXHAUST TERMINATION EXHAUST INTAKE abovegrade, Inches (ram) CONCENTRIC WALL TERMINATION (60G77) LB-49107CE for G32-75 Units Only (331(97) LB-87942 for G32-t00 & -125 Units Only FIGURE 12 12 (305) MIN for 2 (51) Inches(mm) 20(5oa)MAXfor3 (76): UNCONDITIONED SPACE OUTSIDE WALL F PROVIDE SUPPORT FOR INTAKE AND / HI II t2(S_0)ASOVE EXHAUST UNES EVERY 3_(914) 1/2113) FOAM INSULATION IN UNCONOmONED Ii2 (131 FOAM SPACE INSULATION SiDE VIEW WALLRINGTERMINATION (15F74)LE-49107CBfor 2 In.

FIGURE 13 9 -Position terminationends so they are free from any obstructions and abovethe levelofsnowaccumulation (where applicable). Termination ends must be a minimum of 12 inches (305 mm) above grade level. Do not point into window wells, stairwells, alcoves, courtyard areas or other recessed areas. Do not position termination ends directly below roof eaves or above a walkway. Since the G32 is a certified direct vent, Category iV gas furnace, the location of the termination is limited by local building codes. In the absence of local codes, refer to the current National Fuel Gas Code ANSI Z223-1 in USA, and current standard CAN/CGA-B149.1 of the Natural Gas Installation Instructions in Canada for details. The termination should be at least 12 inches (305 mm) from any opening through which flue products could enter the building. When horizontally vented, minimum clearance for termination from electric meters, gas meters, regulators and relief equipment is 4 feet (1.2 m) for US installations. Refer to the current CAN/CGA-B149.1 for installations in Canada or with authorities having local jurisdiction. At vent termination, care must be taken to maintain protective coatings over building materials (prolonged exposure to exhaust condensate can destroy protective coatings). It is recommended that the exhaust outlet not be located within 6 feet (1.8 m) of a condensing unit because the condensate can damage the painted coating. 10 -Suspend piping using hangers at a minimum of every 5 feet (1.52 m) for schedule 40 PVC and every 3 feet (.91 m) for ABS-DWV, PVC-DWV, SDR-21 PVC, and SDR-26 PVC piping. A suitable hanger can be fabricated by using metal or plastic strapping or...
