A.Acceptable boiler/burner manufacturer(s) include(s):

1.Weil-McLain only, as specified in Part 1, Paragraph C.

a)Other manufacturer(s) or other Weil-McLain boiler(s) must comply with specifying engineer’s requirements, including: Full intent of these specifications, and provide complete submittal including literature, wiring diagrams, fuel piping diagrams, and a list of similar installations.

b)Submittal to be presented to specifying engineer at least seven

working days forapproval before bid opening. Substitutions are not permitted after contract is awarded.

c)Energy Management Control System(s) must be tested and approved for installation with specified boiler by boiler manufacturer.

B.Boiler construction

1.Boiler sections

a)Assembled with tie rods.

b)Parallel ground sealed with high temperature silicone sealant to assure permanent gas-tight seal.

c)Sealed water-tight by elastomer sealing rings, not cast iron nipples. Each port opening is machined to accept elastomer sealing rings between sections.

d)Provided with sufficient tappings to install required controls.

2.Boiler(s)

a)Provided with cast-in air elimination to separate air from circulating water.

b)Provided with expansion tank tapping to divert separated air to expansion tank.

c)Constructed to provide balanced water flow through entire section assembly using single supply and return connections for water. No external headers are necessary.

d)Designed with a low silhouette to provide maximum headroom.

e)Elastomer sealing rings are to be used to provide permanent water-tight seal between sections. Unlike cast iron or steel push nipples, the elasticity of the seals fills any gaps caused by misalignment or expansion or contraction.

f)Constructed with high-grade stainless steel burner tubes.

g)Shipped with insulated heavy gauge steel jacket(s) with durable powdered paint enamel finish. Jacket shall have two piece top panel for easier servicing.

h)Provided with built-in tankless heater and 3-way valve for domestic priority.

CGt SERIES specifications

The Weil-McLain CGt Series represents an advanced line of multi-fuel commercial and industrial cast iron boilers designed for high efficiency and sustainability. Renowned for their reliability and superior engineering, the CGt Series offers a robust solution for diverse heating needs, making it a popular choice for facilities like schools, hospitals, and manufacturing plants.

One of the main features of the Weil-McLain CGt Series is its cast iron construction, which ensures durability and longevity. The heavy-duty materials used in the boiler's construction allow it to withstand high operating temperatures and pressures, contributing to the unit's overall efficiency and operational safety. The high thermal mass of the cast iron also provides excellent heat retention for optimal energy savings.

The CGt Series is designed to operate on both natural gas and propane, providing versatility to meet the specific fuel options available in various regions. This dual-fuel capability allows facility managers to switch between fuel sources depending on availability and cost, giving operators greater control over energy expenses.

Another significant advancement in the CGt Series is its integrated control system, which maximizes efficiency through intelligent system management. The control system helps maintain optimal operating conditions and adjusts the boiler's performance according to real-time demand. This level of automation not only enhances energy efficiency but also simplifies maintenance and operation for facility staff.

The series is equipped with high-efficiency burners that enhance combustion, resulting in lower emissions and reduced environmental impact. The innovative design of the burners ensures complete and clean burning of fuel, contributing to lower NOx emissions, which helps facilities comply with stringent environmental regulations.

Moreover, the Weil-McLain CGt Series supports multiple zone heating systems, allowing for tailored heating solutions within large facilities. This capability reflects the series' commitment to customization, enabling users to set different temperatures as per zone requirements and improving overall user comfort.

In conclusion, the Weil-McLain CGt Series combines robust cast iron construction with advanced technologies to provide a reliable, efficient, and flexible heating solution for commercial and industrial applications. Its dual-fuel capabilities, integrated control systems, and high-efficiency burners distinguish it as a leader in the market, making it a preferred choice for energy-conscious organizations aiming to reduce their operational costs while ensuring consistent heating performance.
