Let's take a closer look at a few key features of the Weil-McLain 94 Series boiler.
Forced Draft Firing
Because it's pressurized for forced-draft firing, the 94 Series doesn't need a chimney. Instead, this boiler operates with nothing more than a three foot vent situated on top of the roof.This forced-draft boiler:
Hydro Wall Design
The 94 Series Boiler's Hydro Wall design has an innovative water-backed combustion area with water circulating around the firebox. The sidewalls and crownsheet help create a maximized surface for heat transfer.The Hydro Wall Design also:
With cast iron parts of the boiler not facing the ground, the tougher outer skin is left to protect against corrosion and rust.
No Refractory Combustion Chamber
Because the boiler's combustion area is surrounded by water, the burners for flame retention do not need hot refractory for combustion. This enhanced feature of the 94 helps keep boiler costs low by saving on the combustion chamber materials and the labor required to install it. In addition, there are no future replacement costs.
Section Sealing Method
Every port opening on the 94 boiler features a flexible elastomer sealing ring to help ensure a water-tight, permanent seal between the different sections. This unique sealing method is enhanced by the use of short draw rods to connect sections and help facilitate faster assembly of sections.
As demonstrated in the illustration, the machined surface of the port opening manages the compression ratio of the sealing ring to create a critical water tight seal. The aligning lugs help ensure the sections are properly aligned during assembly. These lugs also permit positive locking of the sections.
Flue Gas Traveler
Combined with an ultra-efficient three-pass design, the Weil-McLain 94 Series boiler has multiple uptakes working to:
By having higher velocities and a longer flue gas travel, the 94 Series boiler increases the absorption of heat of the alternate heating surfaces.
Front Cleanout Opening
To simplify and streamline maintenance and cleanings, the No. 94 boiler boasts two large cleanout doors. These openings offer complete access to the center flueways for unencumbered cleanings. The frameless doors are hinged to a center plate, sealed with a rope and then confirmed to be air tight by the use of wing nuts. As an added measure, the six cleanout plates located on the front of the boiler are rope-sealed and offer quick access for easy maintenance.
Manufactured with Short Draw Rods for Faster & Easier Assembly
Instead of using one long rod and expansion washers, the Weil-McLain 94 employs several short draw rods to ensure the sections are securely and safely tied together. In fact, this is one of the key standard features of all Weil-McLain boilers and is acknowledged by every leading insurance company. These shorter draw rods ensure easier and faster assembly of all of the sections. Tappings can be provided in intermediate, back, and front sections to allow quick access to the water way areas for maintenance and inspections at the bottom of the boiler and above the crown sheet.
No Return Header — Flanged Flue Collar
The Series 94 boiler helps save on material costs and installation time by reducing the need for a separate return header. Condensate or return water enters through the center opening and is then channeled to the right or left port openings by interior vanes in the section.
Supply Outlets for Simplified Piping
By requiring only two or one tow supply outlets, the Series 94 reduces installation time. You'll receive three types of supply outlets as standard equipment based on your boiler size:
- 10-inch flanged top supply outlet
- Supply elbow with an 8-inch flanged opening
- Supply elbow with a 6-inch tapped opening.
The outlets do feature an integrated trap that separates the water from the air.
Integrate Multiple Tankless Water Heaters
The Series 94 boiler can accommodate the installation of up to 8 tankless water heaters. When you choose to use multiple tankless water heaters, you'll enjoy:
- The ability to access hot water at different temperatures
- The ability to have an increased volume of hot water
- The ability to access a single heater for melting snow.
