A core (26) extends through a circular bend (28) greater than 180 degrees to define a first leg (30) between the bend (28) and an inlet manifold (22) and a second leg (32) between the bend (28) and an outlet manifold (24). The legs (30, 32) are disposed in converging relationship from the bend (28) towards the manifolds (22, 24) to define an acute angle (α) between the legs (30, 32). The manifolds (22, 24) are aligned in juxtaposed relationship along an alignment axis (Y) and the legs (30, 32) are disposed in angular relationship to a reference axis (X) to define first and second drainage angles (Θ1, Θ2) between the corresponding legs (30, 32) and the reference axis (X). The second drainage angle (Θ2) is >10 degrees and the first drainage angle is (Θ1)>20 degrees and the acute angle (α) is >10 degrees for draining condensate along the legs (30, 32) toward the juxtaposed manifolds (22, 24) to establish a common drainage point of the condensate.
