Weil-McLain® is now offering an enhanced line of its SlimFit™ high-efficiency condensing gas boilers. The company says new features include improved boiler-to-boiler communication, Modbus® and BACnet® for linking with BAS, express set up wizard, 10 preset typical heating systems, and updated controls interface for simpler navigation, at-a-glance boiler status, diagnostics, and troubleshooting.
The updates to the boilers aim to increase usability and access for installing contractors, consulting engineers, and facility managers. The boiler’s narrow housing offers maneuverability for confined spaces and weight restricted areas, a critical solution for commercial retrofit projects. The units come completely factory assembled allowing for on-site plug-and-play installation.

Other features include a low NOx less than 20 PPM, Modulating Burner with up to 6:1 turndown ratio, flexible venting configurations up to 100 ft, and zero clearance requirements on one side of the boiler for back-to-back installations
