The Weil-McLain SlimFit 750 (SF750) is a high-efficiency commercial condensing gas boiler delivering an input of 750,000 BTU/hr. Designed specifically to excel in light commercial, educational, and institutional retrofits, the SlimFit series features an exceptionally narrow profile paired with integrated roller casters, allowing the unit to maneuver effortlessly through standard doorways and into tight mechanical spaces without specialized rigging.
Key Performance Features:
- Advanced Cast Aluminum Heat Exchanger: Engineered with a durable, sectional cast aluminum block that provides up to 12 times greater thermal conductivity than stainless steel, alongside wide, open waterways that are highly forgiving of older mechanical piping networks.
- Precision Modulation & Turndown: Features a fully modulating stainless steel burner covered with a woven steel fiber mesh, offering a 5:1 turndown ratio that scales fuel input directly to shifting building loads for optimized efficiency.
- Smart Lead/Lag Automation: Comes standard with the proven Unity™ Controller framework, offering direct cascade control for up to 8 boilers simultaneously, outdoor temperature reset curve adaptation, and standard CSD-1 compliance.
Application & Installation Flexibility: Built with a corrosion-resistant composite condensate tray and a block that can be field-disassembled if needed for narrow entries. The SlimFit 750 comes factory-wired and pre-programmed for quick direct vent or direct exhaust applications using PVC, CPVC, PP, or AL29-4C stainless steel materials.
