Required venting: Napoleon 3" x 3" co-linear liner kit + terminal

This direct-vent insert vents up the existing masonry chimney on two 3" flexible aluminum liners (one intake, one exhaust) with a Napoleon co-linear terminal on top. Choose the GDI-320KT / 325KT / 335KT / 345KT kit to match your chimney height and add the GDI-223 (standard) or GDI-229 (high-wind) terminal - the GDI-2320KT family uses a 2" + 3" liner pair where the flue is tight. Do not substitute generic liner - mixing systems voids the listing. Liner lengths and clearances are in the installation manual on this page.
