Answer: PVC, CPVC and ABS pipes are used to vent a condensing furnace. You will select one among these depending on the furnace’s designed exhaust gas temperature. The plastic types that are specified above can withstand various degrees of temperature. PVC is lowest among these. It can tolerate a maximum temperature of 140 degrees F. ABS has maximum toleration level of 160 de grs F. CPVC has the highest at 194 degrees F. If a pipe is made to bear a temperature level that is more than what it can withstand it will sag or leak.
