Weil-McLain Boiler


The Weil-McLain Ultra boiler has been designed for easy installation. The Ultra 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.

    For fast and easy installation, combine an Ultra PLUS
Indirect-Fired Water Heater with your Ultra boiler installation.
Ultra PLUS water heaters come in three sizes:

ULTRA PLUS 40
ULTRAPLUS 60
ULTRAPLUS 80

Combined with an Ultra boiler, the Ultra PLUS water heater provides more domestic hot water when you need it, while taking advantage of the extremely high efficiency of the Ultra boiler. A standard feature of the Ultra boiler control module is domestic hot water priority control, providing quicker response time for domestic hot water demands, along with faster recovery times for the hot water tank. The perfect match for an Ultra boiler is an Ultra PLUS Indirect-Fired Water Heater.
