Weil-Mclain Ultra 155 Serie 2 Boiler Details
The Weil-McLain Ultra 155 Serie 2 boiler integrates advanced PhD Technology, an intelligent system for Precision Hydronic heating. This innovative control module continuously measures and responds to system data, optimizing heating and hot water delivery while maximizing efficiency. It features a robust cast aluminum mono block heat exchanger and sophisticated gas valve, blower, and venturi technologies. These components work in concert to precisely maintain an optimal air and fuel ratio across all firing rates, ensuring consistent performance and efficiency.
At the heart of the Ultra 155 Serie 2 is a pre-mix stainless steel burner with a woven steel fiber mesh. This design enables a remarkable 20-100% modulating firing rate, offering exceptional control and fuel savings. It ensures perfect combustion, resulting in quiet operation, high efficiency, and exceptionally clean exhaust with low NOx emissions. The boiler's low mass cast aluminum mono block heat exchanger is engineered to heat rapidly, delivering warmth to the system much faster than conventional designs and performing optimally in low-temperature condensing applications.
The boiler's Ultra Control Module provides comprehensive system management through a user-friendly 4-digit electronic display with programming buttons and a data port. It simplifies system monitoring and information retrieval, offering both User and Contractor level access. This intelligent module processes inputs from various sensors, including room thermostats, supply and return water temperature sensors, flue gas sensor, domestic hot water aquastat, summer/winter switch, and an outdoor temperature sensor. It dynamically adjusts blower speed and gas flow to precisely match the boiler's output to heating demands.
Designed for ease of installation, the Weil-McLain Ultra 155 Serie 2 boiler boasts minimal clearance requirements and a compact footprint, allowing for both floor standing or wall hung applications. Its thoughtful design includes conveniently arranged water and gas piping connections at either the top or bottom, with most connections accessible from the top for floor-standing setups. Electrical components are pre-wired and clearly labeled on separate line and low voltage terminal strips, facilitating quick and easy field wiring.
Venting is simplified through the use of PVC for both exhaust and combustion air, allowing runs up to an equivalent of 100 feet without messy sealants. The Ultra 155 Serie 2 is lightweight compared to many conventional boilers, featuring side jacket handles and adjustable boiler feet for effortless placement and leveling. A side-mounted service receptacle is included for convenience. Beyond its high AFUE, the boiler is environmentally friendly, producing low NOx emissions and exceeding all current environmental codes, including certification by California's South Coast Air Quality Management District.
