Description: The Aspen and Aspen Light commercial condensing boilers feature a 10:1 turndown ratio, efficiencies of up to 96 percent AFUE, and boast low emissions. With a stainless steel, vertical, firetube heat exchanger, the Aspen line includes seven sizes between 85-399 MBtuh, with a 155-MBtuh combi unit available. All sizes can be wall- or floor-mounted. The Aspen (85-270 MBtuh) has top and bottom supply/return/gas connections for flexibility (non-combi models). The touchscreen control on the Aspen Light Commercial (320 and 399 MBtuh) can be swapped with the boiler logo badge for optimal ergonomics in wall-mount installations. The light commercial models also come with pre-installed wall- and floor-mounting hardware. Each model in the new Aspen line is equipped with advanced Sage2.3 controls.
