Case Study: Emergency Generator Exhaust System Installation for Verizon in Mineola
Project Overview
When Verizon began planning the installation of a new emergency generator at its Mineola facility, they needed a properly designed exhaust system that would perform reliably, meet high-temperature requirements, and be installed with precision. They contacted United Chimney to handle the project from planning through installation.
What began as a straightforward request quickly became a project that required detailed coordination, strong technical execution, and careful attention to logistics. From reviewing architectural drawings and visiting the site to preparing shop drawings, coordinating crane access, and installing the final system, United Chimney managed every step of the process.
The Challenge
Although the project scope was clear from the start, the installation itself required more than a simple vertical exhaust run.
The system needed to support a new emergency generator and include a complete rooftop exhaust assembly. The project also involved installing a silencer, routing the system through multiple offsets, and ensuring the final installation would perform safely and efficiently under high-temperature operating conditions.
One of the biggest considerations was the site itself. The building is located in Mineola, directly adjacent to the Long Island Rail Road. Because the installation required a crane pick to lift the silencer and rooftop components into place, coordination and logistics became a critical part of the job. The team had to evaluate whether notifications or special coordination with the railroad would be required due to crane activity near the tracks.
This was not a straight stack installation. It required planning, collaboration, and field expertise to execute correctly.
United Chimney’s Approach
After Verizon made the initial request, United Chimney reviewed the architectural drawings provided for the generator project. From there, the team conducted a site visit to fully understand the existing conditions and determine the best path forward.
With those conditions confirmed, United Chimney moved into the next phase of the project, which included:
- Reviewing plans and site conditions
- Coordinating logistics related to rooftop access and crane operations
- Evaluating installation concerns due to the site’s proximity to the Long Island Rail Road
- Developing detailed shop drawings
- Submitting drawings for approval
- Ordering the required materials
- Scheduling and completing the installation
By managing both the technical and logistical sides of the project, United Chimney helped keep the job moving efficiently while giving the client confidence that the work was being handled correctly.
The System Installed
United Chimney installed a 14-inch UL-103 high-temperature exhaust system with a full rooftop assembly for the emergency generator.
The completed system included:
- 14-inch UL-103 high-temperature exhaust pipe
- Full rooftop exhaust assembly
- Silencer installation
- Expansion joints
- Multiple offsets and directional changes
- Field-fit adjustable sections
- High-temperature sealing
- Full support systems
Because the layout required multiple offsets and directional changes, the installation had to be carefully fitted in the field to ensure proper alignment, support, and long-term performance.
Installation and Execution
Once approvals were in place and materials were ready, United Chimney mobilized for installation.
The team coordinated crane picks and controlled rooftop staging to safely lift and position key components, including the silencer. With the system routed through multiple offsets rather than a simple vertical run, the crew used field-fit adjustable sections to achieve the required alignment while maintaining the integrity of the exhaust system.
Every part of the installation was completed with a focus on durability, safety, and long-term performance. High-temperature sealing and proper support systems were critical to ensuring the finished system would function as intended under demanding operating conditions.
The Result
The Verizon Mineola project is a strong example of the kind of workmanship and project coordination United Chimney brings to commercial exhaust system installations.
From early planning and shop drawings to crane coordination and final installation, the job required more than just materials and labor. It required a contractor who could understand the site, manage the logistics, and execute the work at a high level.
The result was a fully installed rooftop emergency generator exhaust system built to perform and built to last.
Why This Project Stands Out
This project highlights an important truth about commercial exhaust systems:
These systems only perform as well as they are installed.
Even the best materials depend on proper planning, routing, support, sealing, and installation. On this project, United Chimney delivered all of that while navigating site-specific challenges and maintaining a high standard of workmanship from start to finish.
