Application Considerations
temperatures. Use of PVC, CPVC and other plastic vent materials are inappropriate and hazardous.
Check the manufacturer’s instructions before piping any appliance.
The vent gases of power vented and separated combustion unit heaters may condense on a cold
start-up or when vent piping runs through unheated areas. To protect the heater always pitch both
intake and exhaust piping toward the outside of the building. Remember also that no power vented
equipment can share a common flue with any other appliance. Should a flue become blocked one
appliance could vent into the occupied space.
Approved vent caps should be used on both the intake and exhaust terminations. For greater
convenience Trane offers a concentric vent adapter that allows venting through a single perforation
through the building wall or roof.
