Cement should be applied lightly but uniformly to inside of socket. Take care to keep excess cement out of socket. Apply second coat to end of pipe. 7. Immediately after applying last coat of cement to pipe, and while both inside socket surface and end of pipe are wet with cement, forcefully insert end of pipe into socket until it bottoms out. Turn PVC pipe 1/4 turn during assembly (but not after pipe is fully inserted) to distribute cement evenly. Do not turn ABS or cellular core pipe. NOTE: Assembly should be completed within 20 seconds after last application of cement. Hammer blows should not be used when inserting pipe. 8. After assembly, wipe excess cement from pipe at end of fitting socket. A properly made join will show a bead around its entire perimeter. Any gaps may indicate an improper defective assembly due to insufficient solvent. 9. Handle joints carefully until completely set. Venting Practices FIGURE 18 * See table 2 for allowable pipe. Piping Suspension Guidelines NOTE . Isolate piping at the point where it exits the outside wall or roof in order to prevent transmission of vibration to the structure. SCHEDULE 40 PVC . 5’ all other pipe* . 3’ Wall edistuoedisni24" maximum 3/4" minimum Wall Thickness Guidelines insulation (if required) If this gas furnace replaces a furnace which was commonly vented with another gas appliance, the size of the existing vent pipe for that gas ap- pliance must be checked. Without the heat of the original furnace flue products, the existing vent pipe is probably oversized for the single water heater or other appliance. The vent should be checked for proper draw with the remaining appliance. FIGURE 19 REPLACING FURNACE THAT WAS PART OF A COMMON VENT SYSTEM Exhaust Piping (Figures 22 and 23) 1. In areas where piping penetrates joist or interior walls, hole must be large enough to allow clearance on all sides of pipe through center of hole using a hanger. 2. When furnace is installed in a residence where unit is shut down for an extended period of time, such as a vacation home, make provisions for draining condensate collection from trap and lines. 3. Route piping to outside of structure. Continue with installation following instructions given in piping termination section. The exhaust vent pipe operates under positive pressure and must be completely sealed to prevent leakage of combustion products into the living space. CAUTION Do not discharge exhaust into an existing stack or stack that also serves another gas appliance. If vertical discharge through an existing unused stack is required, insert PVC pipe inside the stack until the end is even with the top or outlet end of the metal stack. CAUTION Page 16 of 57 Issue 1108 506724-01 Vent Piping Guidelines This gas furnace can be installed as either a Non-Direct Vent or a Direct Vent gas central furnace. NOTE: In non-Direct Vent installations, combustion air is taken from indoors and flue gases are discharged outdoors. In Direct Vent installations, combustion air is taken from outdoors and flue gases are discharged outdoors. Intake and exhaust pipe sizing - Size pipe according to Tables 4 and 5. Table 4 lists the minimum vent pipe lengths permitted. Table 5 lists the maximum pipe lengths permitted. Regardless of the diameter of pipe used, the standard roof and wall terminations described in section Exhaust Piping Terminations should be used. Exhaust vent termination pipe is sized to optimize the velocity of the exhaust gas as it exits the termination. Refer to Table 6. In some applications which permit the use of several different sizes of vent pipe, a combination vent pipe may be used. Contact Allied Air Technical Service for assistance in sizing vent pipe in these applications. NOTE: It is acceptable to use any pipe size which fits within the guidelines allowed in Table 5. NOTE: The exhaust collar on all models is sized to accommodate 2” Schedule 40 vent pipe. In horizontal applications, transition to exhaust pipe larger than 2” must be made in vertical runs of the pipe. A 2” elbow must be added before the pipe is transitioned to any size larger than 2”. This elbow must be added to the elbow count used to determine acceptable vent lengths. Contact the Application Department for more information concerning sizing of vent systems which include multiple pipe sizes. FIGURE 20 12" max of straight pipe Exhaust Pipe 12" Min. NOTE . Exhaust pipe MUST be glued to furnace exhaust fittings. NOTE . All horizontal runs of exhaust pipe must slope back to- ward unit. A minimum of 1/4" (6mm) drop for each 12" (305mm) of horizontal run is mandatory for drainage. NOTE . Exhaust piping should be checked carefully to make sure there are no sags or low spots.
