Ascent Deep Series Parts

Building on the popularity of Napoleon’s Ascent Series, the new Ascent Deep fireboxes offer premium depth with all the key features and options that builders and remodelers rely on. The Ascent Deep is available in 2 models, both 22" deep. The D42 and DX42 offers a versatile range of options for design flexibility – with decorative brick panels, fronts and trims. The addition of optional heat management; an industry first in this segment, allows for reduction in  clearance to combustibles, which reduces distance to sensitive items like TVs, sound equipment and artwork. Making your home layout more comfortable for years of enjoyment.
