Weil-Mclain Ultra Series 3 High Efficiency Condensing Boiler

The Weil-McLain Ultra Series 3 boiler has been designed for easy installation. The Weil McLain Ultra Series 3 boiler requires minimal clearance and minimal floor space, and the same boiler can be used in floor standing or wall hung applications.

Water and gas piping is conveniently arranged for connection at the top or bottom of the boiler. In fact, when using the boiler in a floor standing application, all boiler connections are on the top of the boiler except for the condensate drain.

The electrical components have been pre-wired and labeled on separate line voltage and low voltage terminal strips. Terminal strips are provided for quick and easy field wiring. Venting has been simplified by using PVC for both exhaust and combustion air. Slide the PVC into the top outlet flue pipe adaptors and tighten the restraining ring. No messy sealants required. You can even achieve vent runs up to the equivalent of 100 feet.

The Ultra comes with a side mounted service receptacle on a separate circuit for use with a condensate pump, service equipment or service light. The Ultra boiler is lightweight compared to a conventional boiler. Side jacket handles are provided for easy handling along with four adjustable boiler feet for easy placement and leveling.

All Ultra boilers feature AFUE efficiencies in the range of 92.0 - 93.0%. These are some of the highest efficiencies in the industry, however, Ultra boilers, when used in common low temperature applications have annual efficiencies of 98.0%. The Weil McLain Ultra Series 3 boiler exceeds all of the requirements of the Department of Energy’s ENERGY STAR program. Besides being Ultra High Efficient, the Ultra boiler is environmentally friendly. Through PhD Technology and the use of our high grade burner, the Ultra boiler produces less NOx while exceeding all current environmental codes and is certified by South Coast Air Quality Management District (Rule 1146.2) in California.
