Do not use cellular foam core pipe for
exhaust.
The vent connection for the appliance is secured with a clamp
on the appliance exhaust adapter. All other vent connections
must be glued, except PP and flex PP. Slide the vent pipe into
the exhaust adapter. The exhaust pipe must be properly
supported and must be pitched a minimum of a ¼ inch per foot
back to the appliance. This allows the condensate to drain
properly.
