Weil McLain takes condensing boiler technology to a higher level of performance. The Ultra Series 4 features a state of the art heat
exchanger with nanotechnology coating that works like "Ultra Armor", reducing build up in the heat exchanger while maintaining high
efficiency. Nanotechnology is a heat exchanger coating that combines anti-adhesive and anti-corrosion properties, which protects the heat
exchanger from corrosion and combustion residue build up. In conventional systems, aggressive exhaust particles can attach to the surface
and cause heat exchangers to corrode. Heat transfer is then reduced and the heating system's energy efficiency decreases. With
nanotechnology properties, biofilm formation is inhibited and allows residues to be easily carried out of the heat exchanger before they
obstruct the flueways. In addition, Ultra Series 4 has an advanced condensate management system that incorporates polypropylene piping to
further reduce the impact of condensate. Thanks to our nano-coated heat exchanger, the Ultra Series 4 requires no cleaning for a full five
years after installation. When it's time to clean, a simple rinsing of the coated heat exchanger with water does the trick. The Ultra Series 4 is
an ideal choice for single family residential applications. Homeowners will appreciate its quiet operation, ease of set up and control, and
unmatched comfort while providing immediate payback in energy savings. For light commercial applications, the Ultra Series 4 lets
contractors pair boilers in sequence to heat larger buildings. And, it allows you to control multiple boilers from a single control panel. Back-lit
LCD display and simple programming buttons make entering and receiving information easy. The homeowner has the ability to view current
boiler status, check water and outdoor temperatures, review boiler maintenance schedule and view installing contractor contact information.
Features
Includes an LP gas orifice for conversion
31,000 BTU minimum input - 155,000 BTU maximum input
3 inch PVC, CPVC, Polypropylene or Stainless Steel vent pipe

The Weil McLain GV90+ boiler has a durable cast iron primary heat exchanger that extends product life - it is not uncommon for cast iron
boilers to last in excess of 40 years. A corrosion resistant stainless steel condensing secondary heat exchanger increases efficiency up to
5% by recouping heat energy from exhaust normally wasted when vented from the building. The extra heat energy is then added and
circulated through the baseboard or radiators to efficiently heat the home. Unlike most high efficiency boilers in the industry, the Weil
McLain GV90+ has extra-wide waterways (over 2 inches) allowing sludge and debris, often present in older systems, to flow through easily.
This limits scale build up, which reduces boiler efficiency, performance and can lead to premature boiler failure. Down fired, counter flow
boiler design improves boiler efficiency. The GV90+ offers 5 pass design in the primary heat exchanger and 2 pass design in the secondary
heat exchanger maximizing heat transfer and optimizing boiler efficiency. Built in dual circulator strategy provides boiler protection - it can
accept low return water temperatures (down to 60 degrees) with no additional mixing valves, pumps, wiring and installation labor. The
lower water temperature also allows homeowners the flexibility to add radiant heating for kitchens, baths or other living spaces without the
added cost of special return temperature controls.

The Weil McLain Evergreen Pro boiler extends comfort levels to every area of your property for the long run. The Evergreen Pro is perfect for
residential applications or light commercial and single or multi-unit installations with ZoneStacking up to 24 programmable zones. It's everything
you want in heating: quiet operation, aesthetically pleasing design, floor standing or wall mount options, environmental sustainability, heating
comfort while optimizing energy savings. The setup wizard efficiently guides the installer through a single or multiple boiler installation in
minutes. For the contractor, installer and / or service provider, the Evergreen Pro has an easy to understand graphical user Interface and makes
programming and monitoring operations simple. The wiring diagrams provided are clear and easily accessible. The quiet operation of the
Evergreen Pro further enhances the sense of "invisible" heat, from multiple in home zones to pool heating. For the homeowner who wants
heating comfort while maintaining lower utility bills and reducing their carbon footprint, the Evergreen Pro 220 boiler has earned Energy
Star rating, with an impressive 95% AFUE rating. This could qualify the homeowner for local utility rebates, if available. The Evergreen Pro's
smooth performance adds to the greener environment sustainability with straightforward, user friendly design with advanced technology.
Simple user interface with complex calculations behind the scenes of the required energy to meet system demands is distributed across
all the boilers in the network. The system maximizes user's comfort by simultaneously meeting as many system demands as possible: When
there are multiple requests on a cascaded boiler system, the control satisfies both local and network heating demands. The built in
installation wizard asks direct questions on setup, making customization easy and straightforward. Contextual help is also available on screen.
