Square termination (SV4.5HTS) shown. Round Termination (SV4.5HTR) may only be used on D-500, D-600 and DR-500, DR-600 series models. The Small Square Termination (SV4.5HTSS) may only be used on D-500 and DR-500 series models.

See Table 3 on page 17 as an aid in venting component selection for a particular range of exterior wall thicknesses.
