The Wrong Venting System Can Limit Appliance Performance And Complicate Installation

Boilers, water heaters, generators, and other fuel-fired equipment produce very different exhaust conditions. Flue-gas temperature, operating pressure, condensate formation, appliance input, vent diameter, and required routing all influence how the exhaust system must be designed. A vent system that is not appropriate for those conditions can create draft and pressure problems, condensate concerns, clearance conflicts, or difficulties meeting the appliance and code requirements.

The building creates another set of constraints. Mechanical-room congestion, structural penetrations, long horizontal runs, vertical stack heights, rooftop terminations, and limited installation access can make rigid or heavily field-fabricated venting difficult to coordinate. When the vent system cannot adapt to the actual route, contractors may face additional field modifications, installation labor, and project delays.

Build The Exhaust System Around The Appliance And Vent Route

Jeremias manufactures modular stainless-steel exhaust systems that can be configured around the appliance operating conditions and the physical path the vent must follow. Single- and double-wall systems, multiple diameters, fittings, supports, transitions, terminations, and connection options allow the exhaust path to be assembled from engineered components rather than extensively fabricated in the field.

Different system constructions provide options for condensing and non-condensing appliances as well as varying temperature and pressure requirements. Conical and flanged connection systems, corrosion-resistant stainless-steel construction, and insulated double-wall options allow the vent system to be selected according to the exhaust conditions, installation environment, and applicable system requirements.

Lightweight System Design

Engineered for easy handling during rooftop or mechanical room installation without sacrificing durability.

Venting Designed Around What Happens Between The Appliance And The Termination

High-efficiency equipment can produce cooler exhaust and acidic condensate that place different demands on a vent system than traditional higher-temperature appliances. Jeremias offers stainless-steel venting configurations designed for different exhaust temperatures, pressures, and condensate conditions, allowing the vent construction to be matched to the appliance instead of treating every flue application the same.

The path from the appliance to the termination can be just as challenging as the exhaust itself. Horizontal offsets, vertical rises, equipment-room congestion, structural penetrations, and rooftop conditions all influence how a vent system must be routed and supported. Modular fittings, lengths, supports, transitions, and termination components allow the exhaust path to be developed around these building conditions while reducing dependence on field-fabricated sections.

Wall construction also serves a practical purpose beyond simply providing another product option. Single-wall systems can address applications where installation conditions and required clearances permit their use, while insulated double-wall construction can help manage exterior surface temperatures and maintain flue-gas temperatures where the application requires it. The appropriate construction can therefore be selected around both exhaust performance and the surrounding building conditions.

Modular construction also changes how the system is installed and modified. Factory-manufactured sections and engineered connections reduce the amount of field fabrication required, while individual components provide flexibility when routing changes, equipment replacement, or future system modifications require portions of the exhaust system to be reconfigured.

Installation/Usage Information

Design The Vent Around The Appliance And Complete Exhaust Path

Vent selection and installation should account for appliance type and input, flue-gas temperature, operating pressure, condensate conditions, required diameter, total developed length, fittings, vertical rise, horizontal runs, termination location, and applicable clearances. Supports, penetrations, expansion provisions, drainage, and termination components should be coordinated as part of the complete system rather than treating the vent as individual pieces of pipe.

Maintain Proper Support, Drainage, And Joint Integrity

During installation and service, vent sections should remain properly supported and joints assembled according to the requirements of the selected Jeremias system. Condensing applications require particular attention to condensate collection and drainage, while supports, connections, seals, terminations, and exposed sections should be periodically inspected for conditions that could affect the integrity of the exhaust path.

Featured HealthWay Project

Rockefeller Group Improves Overall IAQ And Saves Money

New York, New York

 

The Challenge

The Rockefeller Group faced a significant challenge with 1271 Avenue of the Americas, a historic building in midtown New York City that required a modern air quality solution. Despite the building’s historic nature, the goal was to improve overall indoor air quality (IAQ) while achieving operational cost savings and reducing the carbon footprint. The existing system included 38 air handling units (AHUs) serving 48 stories, moving 1 million CFM across four mechanical floors. The AHUs were equipped with MERV 15 filter arrays, which, while effective, did not meet the Rockefeller Group’s vision for world-class IAQ.

The Solution

To address this challenge, the Rockefeller Group partnered with Gil-Bar and HealthWay to design and implement a comprehensive retrofit solution. This involved installing HealthWay Inline air purification modules featuring their proprietary Disinfecting Filtration System (DFS) technology. A total of 660 HealthWay inline modules were installed, replacing the existing filter racks with HealthWay 1000/2000 modular arrays. This new setup was designed to enhance air filtration without the drawbacks typically associated with higher filtration levels, such as restricted airflow and increased energy demands.

The Outcome

The retrofit of 1271 Avenue of the Americas was a resounding success, marking it as the largest building in New York to utilize HealthWay DFS technology. Third-party testing showed that the DFS technology removed 99.93% of 0.3-micron particles in a single pass, significantly improving IAQ. Additionally, the HealthWay DFS filters reduced the pressure drop to 0.205” wc, compared to 0.550” wc with the previous MERV 15 filters, easing the demand on the fan motors and significantly cutting energy use. As a result, the Rockefeller Group reported a 60% reduction in fan energy consumption, illustrating both cost efficiency and environmental benefits.

Key Takeaways

  • Successful implementation of advanced IAQ solutions in a historic New York City building.
  • Collaboration with Gil-Bar and HealthWay led to innovative and effective retrofit strategies.
  • The HealthWay DFS technology provides superior particulate removal and reduces energy consumption.
  • The project highlights the Rockefeller Group’s commitment to sustainability and operational efficiency while maintaining the integrity of a historic landmark.
