 Weil-Mclain Ultra
Series 3 High Efficiency Condensing Boiler
Weil-Mclain Ultra Series
3 Boiler Pricing
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.
