Default TruSeq PCR Free question

I am preparing samples using the TruSeq DNA PCR Free library kit with UDI adaptors. The PI has requested that we perform Pippin Prep post adaptor ligation to remove adaptor contamination and target a narrow size distribution. Question is... because the protocol does not include denaturation prior to the final sequencing step, the non-homologous Y-shaped adaptors results in an atypical migration pattern on agarose gel and the Bioanalyzer results are substantially larger (750bp) than would be predicted (~350bp insert +adaptor range). Should I heat denature the samples prior to putting on Pippin Prep? Thoughts?
