NY Thermal Recalls Boilers Due to Carbon Monoxide Hazard

What was recalled

In May of 2018, the U.S. Consumer Product Safety Commission (CPSC) announced a significant recall involving gas-fired boilers manufactured by NY Thermal, also known as NTI. This action was taken to address safety concerns regarding specific units sold under two distinct brand names: Trinity Tft and Slant/Fin. These are not small, portable heaters; they are substantial heating systems designed for both residential homes and commercial buildings, intended to provide warmth through hot water or steam distribution. The scope of this recall is quite broad, covering a wide range of model numbers within these two product lines that were marketed for their efficiency and reliability in keeping spaces comfortable during colder months.

The recalled Trinity Tft boilers are easily identifiable by the "NTI" name printed prominently on the front of the unit. These models were finished in a metallic-grey color, giving them a sleek, industrial appearance suitable for utility rooms or mechanical closets. The recall encompasses a specific size progression within this line. Smaller units, ranging from the Trinity Tft60 through the Tft250, measure 33 inches tall by 20 inches wide. Larger capacity models, specifically the Trinity Tft300 through Tft399 series, are slightly bigger, measuring 36 inches tall and 25 inches wide. Each of these individual model numbers, from the Tft60 up to the Tft399, has been included in this safety notice due to the potential defect in their internal sealing components.

Simultaneously, the recall affects boilers sold under the Slant/Fin brand, specifically those labeled with the "CHS" designation. Unlike the Trinity line, these units feature the name "Slant/Fin" and "CHS" printed across the bottom front of the boiler. They were typically sold in a standard white finish. The affected Slant/Fin CHS models follow a similar sizing structure to the Trinity line. Models CHS-85 through CHS-250 measure 33 inches tall by 20 inches wide, while the larger CHS-300 through CHS-399 models measure 36 inches tall and 25 inches wide. For both brands, the definitive way to identify if a unit is part of this recall is to check the nameplate located on the right side of the boiler, which lists the specific model and UPC numbers. Consumers should verify their specific unit against the list provided by NY Thermal, as certain models within the CHS line (such as CHS-155, CHS-300, and CHS-340) had unavailable UPC data in some records, making visual inspection of the model number critical.

These boilers were sold across the United States for use in both residential and commercial settings. They are complex pieces of equipment that require professional installation, meaning they are likely found in the basements, mechanical rooms, or utility closets of homes and businesses installed by licensed distributors. The recall serves as a critical reminder to property owners and building managers to verify the status of their heating infrastructure, ensuring that these specific NY Thermal units are inspected and repaired to prevent any potential safety hazards associated with their operation.

The hazard, explained

To understand why this recall is necessary, it helps to look closely at the specific mechanical failure involved. The issue centers on a small but critical component known as the grommet seal within NY Thermal (NTI) gas boilers. In normal operation, these boilers burn natural gas or propane to generate heat for your home or business. This combustion process creates byproducts, including water vapor and carbon monoxide. Modern high-efficiency boilers are designed to capture some of that waste heat, which causes the exhaust gases to cool down and condense into water before leaving the unit. This is where the grommet seal plays a vital role: it acts as a barrier, ensuring that these internal fluids remain contained within the boiler’s combustion chamber and exhaust pathways.

However, over time, this grommet seal can undergo a physical change that compromises its integrity. According to reports from the manufacturer, the seal can reduce in size. As it shrinks, it may eventually dislodge or become loose during regular use. When this happens, the protective barrier is broken. This failure allows two dangerous substances to escape their intended path: condensation and carbon monoxide. While leaking condensation can cause water damage to your property, the more immediate and severe danger is the release of carbon monoxide (CO) into the living space.

Carbon monoxide is often called the "silent killer" because it is completely odorless, colorless, and tasteless. You cannot detect its presence with your senses. When the grommet seal fails, CO leaks from the boiler instead of being safely vented outside. If this gas accumulates in a room, it displaces oxygen in the air. When humans breathe in carbon monoxide, it binds to hemoglobin in the blood much more strongly than oxygen does, effectively starving the body’s tissues and organs of the oxygen they need to survive.

The symptoms of carbon monoxide poisoning can mimic common illnesses, making them easy to miss or misinterpret. Early signs often include headaches, dizziness, nausea, and confusion. As exposure continues, these symptoms can rapidly worsen to include vomiting, loss of consciousness, and eventually death. Because the gas is undetectable without specialized equipment, a small leak that goes unnoticed can become fatal before anyone realizes what is happening. This is why the CPSC has issued this recall: even though no injuries have been reported so far, the potential for serious harm is significant due to the invisible nature of the hazard.

It is also important to note that this is not just a one-time event. The deterioration of the grommet seal is a progressive issue. It does not necessarily fail all at once but worsens with use and time. This means that a boiler that was safe when installed may become hazardous months or years later. This gradual progression makes regular inspection and professional repair essential, rather than waiting for an obvious malfunction to occur. The remedy provided in this recall—a free repair by the installer or distributor—is designed to replace or restore this seal before it reaches the point of failure, thereby eliminating the risk of CO leakage entirely.

Who is most at risk

When we discuss a carbon monoxide hazard in residential and commercial heating systems, the question of "who is at risk" extends beyond just owning the equipment. It involves understanding who lives or works in those spaces and how their bodies might react to this silent threat. The recalled NY Thermal boilers—including the Trinity Tft and Slant/Fin CHS models—are designed for both homes and businesses. This means the people potentially exposed are not limited to homeowners; it also includes employees, customers, or visitors in commercial settings where these units are installed.

Carbon monoxide (CO) is particularly dangerous because it is odorless, colorless, and tasteless. You cannot see it, smell it, or feel it until symptoms appear. For the general population, early warning signs might include a dull headache, dizziness, nausea, or confusion. However, certain groups are physiologically more vulnerable to lower levels of exposure or may not recognize the symptoms in time to evacuate. These include infants, young children, older adults, pregnant women, and individuals with pre-existing heart disease, anemia, or chronic respiratory conditions like asthma or COPD.

Why are these groups at higher risk? Carbon monoxide binds to hemoglobin in your blood much more strongly than oxygen does, effectively starving your tissues of the oxygen they need to function. Infants and young children have faster breathing rates and smaller lung capacities, meaning they inhale more air—and potentially more CO—relative to their body size. Their developing bodies are also less able to process toxins. Older adults may experience symptoms that mimic normal aging or other medical conditions, such as fatigue or mild confusion, leading them to dismiss the danger. Pregnant women carry a fetus whose hemoglobin has an even higher affinity for carbon monoxide than adult hemoglobin, posing a severe risk to both mother and child.

In commercial settings, the risk is compounded by occupancy density. A boiler failure in an office building, school, or retail space could affect dozens of people simultaneously. Employees with health conditions might not have the luxury of leaving work immediately if they feel unwell, especially if they are unaware that their heating system is the culprit. Additionally, individuals who are sleeping in the same area as a leaking boiler—whether in a residential bedroom or a break room—are at extreme risk because they may not wake up to the subtle early signs of poisoning.

While the recall notice states that no injuries have been reported to date, the potential for harm is real and immediate if the grommet seal deteriorates and carbon monoxide enters the living space. The fact that three incidents of condensation and CO leakage have already occurred underscores that this is not a theoretical risk but an active one. Therefore, anyone residing in or working in a building equipped with these specific NY Thermal boilers should consider themselves potentially at risk until the unit has been professionally repaired.

It is also important to note that the hazard is not limited to those who directly operate the boiler. Carbon monoxide can spread through HVAC ducts and open doorways, affecting adjacent rooms or floors. This means that even if you do not have direct access to the mechanical room where the boiler is installed, you could still be exposed if the seal fails and the gas disperses into your living area. This widespread dispersion potential makes the risk applicable to every member of a household or workplace, regardless of their proximity to the unit.

How to tell if you have the recalled item

Before you take any action or contact anyone for a repair, it is critical to confirm whether your specific boiler is actually part of this recall. The affected products are gas boilers manufactured by NY Thermal (NTI) and sold under two primary brand names: Trinity Tft and Slant/Fin CHS. These units were intended for both residential and commercial use, so they may be installed in homes, apartments, or small business buildings. Because the visual appearance and dimensions differ significantly between the two brands and their respective model sizes, you need to look at several specific details on your unit to be sure.

The first step is to identify the brand name printed on the front of the boiler. If you have a Trinity Tft model, you will see the name "NTI" printed clearly on the front. These units were sold in a metallic-grey finish. In contrast, if you have a Slant/Fin CHS model, the name "Slant/Fin" along with "CHS" will be printed across the bottom front of the unit. These models were sold in white. This visual distinction is your first clue, but it is not enough on its own, as both brands come in different sizes.

Next, you must check the physical dimensions of your boiler and the specific model number. For Trinity Tft models, there are two size categories. Smaller units, ranging from model Tft60 through Tft250, measure 33 inches tall by 20 inches wide. Larger units, from model Tft300 through Tft399, are taller at 36 inches and wider at 25 inches. For Slant/Fin CHS models, the sizing follows a similar pattern: models CHS-85 through CHS-250 measure 33 inches tall by 20 inches wide, while the larger CHS-300 through CHS-399 models measure 36 inches tall and 25 inches wide.

To be absolutely certain, you need to locate the nameplate. This plate is attached to the right side of the boiler and contains both the model number and the UPC (Universal Product Code) number. You should cross-reference these numbers against the official list of recalled models. For Trinity Tft boilers, the recalled models include the Tft60, Tft85, Tft110, Tft155, Tft175, Tft200, Tft250, Tft300, Tft340, and Tft399. For Slant/Fin CHS boilers, the recalled models are the CHS-85, CHS-110, CHS-175, CHS-200, CHS-250, and CHS-399. Note that UPC numbers for certain Slant/Fin models (CHS-155, CHS-300, and CHS-340) were not available in the recall records, so checking the model number is essential for those specific units. If your boiler matches these descriptions and numbers, it is part of this recall.

What to do — step by step

Your refund, repair, or replacement options

If you own one of the recalled NY Thermal boilers, the most important thing to know right now is that the company has established a clear and accessible path to resolve the issue without costing you anything out of pocket. The official remedy for this recall is not a refund or a free unit replacement, but rather a comprehensive, free repair performed by a professional. This decision makes sense when you look at the nature of the defect: the grommet seal that sits within the boiler’s internal mechanism can shrink and eventually fall out over time. Because this is a specific mechanical failure point rather than a fundamental design flaw that affects the entire lifespan of the unit, repairing that specific seal restores the equipment to its intended safe operating condition. The manufacturer, NY Thermal (also known as NTI), has taken responsibility for this repair and will cover all associated costs.

To initiate this process, you need to reach out directly to the person or company that installed your boiler. This is often the most convenient step because your installer already has the records of your specific system, knows the layout of your home’s piping, and understands the local codes that apply to your installation. If you no longer have contact information for your original installer, or if they are no longer in business, you should contact NY Thermal directly. You can call their dedicated recall line at 800-688-2575. Their support team is available from 7 a.m. to 4 p.m., Eastern Time, Monday through Friday. When you call, be prepared to provide the model number and the UPC number found on the nameplate located on the right side of your boiler so they can verify that your specific unit is part of this recall.

Alternatively, if you prefer to handle things online first or need more detailed technical instructions before calling, you can visit the company’s website at www.NTIboiler.com. Once there, look for the “Urgent Recall Advisory” link located at the very top of the homepage. This section will provide you with the latest updates and potentially help you locate an authorized service provider in your area if you cannot reach your original installer. It is crucial that you do not attempt to fix this grommet seal issue yourself. Because the hazard involves carbon monoxide, a colorless and odorless gas that can be deadly, any repair must be done by a qualified technician who understands how to properly seal the combustion chamber and test for leaks after the work is complete.

Please remember that while you are waiting for your appointment to get the free repair scheduled, you should not simply ignore the risk. If you have no choice but to keep using the boiler before the repair is completed, you must take extra precautions. Ensure that you have a working carbon monoxide alarm installed outside of every sleeping area and on every level of your home. These alarms are your primary defense against the very real danger posed by a leaking seal. By acting quickly to schedule your free repair, you ensure that your heating system remains both efficient and safe for your family.

What can happen if you ignore it

When a recall involves carbon monoxide, the stakes are inherently higher than with many other consumer product issues. Ignoring this notice is not simply a matter of delaying a convenient repair; it is about accepting an ongoing, invisible risk inside your home or business. The core problem lies in the grommet seal on these specific NY Thermal boilers. Over time, this component can shrink and eventually dislodge while the unit is running. When that happens, the boiler may leak condensation and, more critically, carbon monoxide gas directly into the surrounding environment.

Carbon monoxide is often described as the "silent killer" for good reason. It is a colorless, odorless, and tasteless gas, meaning you cannot see it coming or smell it to know it is there. If the seal fails and you continue to use the boiler without addressing the issue, you are essentially allowing this hazardous gas to accumulate in your living space. The consequences of prolonged exposure can range from mild symptoms—such as headaches, dizziness, nausea, and confusion—to severe health complications or even death. Because the gas is undetectable by human senses, relying on feeling "off" is a dangerous strategy. You might not realize you are being poisoned until it is too late.

According to the official recall information from the Consumer Product Safety Commission (CPSC), there have already been three reported incidents involving these exact models where the grommet seal deteriorated or became dislodged, leading to leaks of both condensation and carbon monoxide. While the firm reports that no injuries have occurred so far, this is a sobering reminder of how close things were to going wrong. The fact that leaks have been confirmed in multiple units shows that this is not a theoretical risk; it is a known failure mode that happens in real-world use. Ignoring the recall means you are gambling with that same probability.

Beyond the immediate health threat, allowing the boiler to operate with a compromised seal can lead to secondary damage. The leaking condensation mentioned in the reports can cause water damage to floors, walls, and nearby structures over time. This creates a damp environment that can promote mold growth, adding another layer of health concerns to an already dangerous situation. Furthermore, a boiler operating with a faulty seal may burn fuel inefficiently, potentially driving up your energy bills while still failing to provide safe heating.

The most difficult aspect of this hazard is that it often goes unnoticed until symptoms appear in people or pets. If you ignore the recall, you are removing one of the few layers of defense against a gas that can incapacitate you quickly. The CPSC and NY Thermal urge immediate action not to cause panic, but because the window for safe operation closes the moment that seal fails. Continuing to use the unit is an active choice to live with an uncontrolled source of poison in your home. There is no safe level of carbon monoxide exposure in a residential setting, and delaying repair only extends the time you are exposed to this preventable danger.

Staying safe: broader tips

While this specific recall highlights a manufacturing defect in certain gas boilers, the underlying danger—carbon monoxide poisoning—is a silent threat that affects many households with fuel-burning appliances. Because carbon monoxide is odorless, colorless, and tasteless, you cannot detect it without proper equipment. Therefore, relying solely on the mechanical integrity of your heating system is not enough. The most effective layer of protection is early detection through properly maintained alarms. Place battery-operated or hardwired carbon monoxide alarms outside every sleeping area and on every level of your home, including the basement. This placement ensures that if a leak occurs while you are resting or in another part of the house, you will hear the warning before symptoms like headaches, dizziness, or nausea set in. Test these alarms monthly and replace the batteries at least once a year, or when the device chirps a low-battery signal.

Beyond alarms, routine professional maintenance is critical for gas-fired equipment like boilers, furnaces, and water heaters. Even if your unit is not part of a recall, it should be inspected annually by a qualified HVAC technician. During this service, the technician checks for proper venting, ensures there are no cracks in the heat exchanger that could allow combustion gases to escape into your living space, and verifies that the burner is operating efficiently. Poor ventilation or blocked flues are common causes of carbon monoxide buildup, regardless of whether the appliance itself is defective. If you notice any signs of incomplete combustion, such as sooty stains around appliances, pilot lights that frequently blow out, or excessive moisture on windows near heating units, have the system checked immediately.

You can also take proactive steps to stay informed about safety issues without waiting for a crisis. Subscribe to email alerts from the U.S. Consumer Product Safety Commission (CPSC) and check their website regularly for new recalls. Many people do not realize that recall notices often provide direct links to registration forms or automatic notifications, so registering your appliances with the manufacturer when you purchase them is a simple way to ensure you are reached quickly if a safety issue arises. Additionally, never use gas ovens or stovetops to heat your home, and always ensure that fuel-burning devices are vented directly to the outside. By combining working alarms, regular professional inspections, and staying informed through official government channels, you create a comprehensive safety net that protects your family from both known defects and general household hazards.
