The company’s comments, in its own words

(3/24/2023) Weil-McLain: Weil-McLain provides this response based on the limited information available in the Incident Report. Despite our efforts, we have been unable to make contact with the consumer and obtain the additional information needed to investigate this claim. Weil-McLain would be in a better position to provide a more detailed response if it were able to obtain maintenance records, photographs and details of the claimed incident. At this time, Weil-McLain does not have sufficient information to provide a substantive response and has questions surrounding the operation, service and maintenance of the boiler and related equipment prior to the incident. If we are contacted by the consumer and learn more, we will amend this response.

The product, in the report: Gas fired boiler in the basement manufactured by Weil-Mclain Inc. and installed professionally by Robbins Air Inc..

The Weil_mclain gas boiler in my house has a serious defect or design flaw. The cover plate on the heat exchanger warped and the seal was missing letting the flame burn a hole thru the outside exterior cover. This condition could have caused the house to burn down or worse! I contacted the manufacture and they refused to reimburse me for the repair stating the maintenance was not performed to prevent this disaster. .

The company’s comments, in its own words

(3/16/2018) Weil-McLain: NOTE: Weil-McLain previously responded to CPSC Investigation Report No. [REDACTED] regarding this same incident. We are providing our response to that Investigation Report in our comments below. Please note that our comments below reference materials and information provided with the Investigation Report that were not included with this Incident Report.
Consumer initially contacted Weil-McLain on 10/3/2017 seeking replacement of the heat exchanger cover and gasket for a Weil-McLain Ultra-230 boiler that had been installed on 12/11/2009 by the prior owner of the Consumer’s residence. Consumer informed Weil-McLain that he was neither the initial retail purchaser of the boiler, nor was Consumer able to provide Weil-McLain with any indication that the subject boiler had been properly maintained by a qualified service technician, the Consumer himself or the prior owner of the boiler. Among other things, the Limited Warranty applicable to the subject boiler excludes:
• Products that are no longer owned by the first retail purchaser (Warranty, paragraph 2); and
• Products that fail or malfunction as a result of improper or negligent care or maintenance (Warranty, paragraph 8).
On 10/03/2017, Weil-McLain denied Consumer’s warranty claim based upon the information provided by Consumer himself and the above-referenced exclusions in the Limited Warranty (paragraphs 2 and 8).
Routine maintenance specified in the Manual for the subject Ultra-230 boiler would have prevented the condition experienced by this Consumer.
The Boiler Manual for the subject boiler provides specific instructions for Annual Startup and General Maintenance that was required to be done on the boiler (starting at page 92 of the Manual). The vertical bar to the left of the Column outlining the instructions for the Service Technician contains a legend reading “ANNUAL START-UP (See First–year special inspection)”. The First-Year Special Inspection instructions, which appear on the next page of the Manual (page 93) provide detailed instructions relating specifically to the heat exchanger cover plate and the associated gasket. This maintenance is to be performed within 12 months of the installation of the boiler. Thereafter, the same inspection procedure is to be included as part of the routine service done at the annual start up at the beginning of each heating season. In the event that the heat exchanger needs to be cleaned, page 111 contains additional instructions for the service technician to follow; these instructions also include the removal, inspection and replacement of the heat exchanger cover plate and its associated gasket.
The foregoing requirement for annual inspections of the cover plate would have prevented the condition experienced by this Consumer. In this instance, it appears that neither this Consumer nor the prior owner of the residence had arranged for a qualified service technician to annually inspect or service the heat exchanger cover plate or its associated gasket - or the boiler generally. This permitted the deterioration of the gasket for the heat exchanger cover to deteriorate undetected. As the deterioration of the gasket continued over the course of years, it eventually allowed hot combustion gas to leak from the inside of the heat exchanger, between the cover plate and the body of the heat exchanger and consume the gasket (which is why the photos show a missing section of the gasket material). The continued leakage of hot combustion gas due to the gasket failure would also have eventually warped the heat exchanger cover plate as shown in the photos.
We note that the Consumer reported that he arranged for the local gas utility company to inspect the boiler when the Consumer purchased the residence from the prior owner. Consumer reports that the gas company inspection occurred on 10/26/2014, and that no issues were noted at that time. Typically, a gas utility will check for gas leaks, but would most likely not have performed maintenance on the boiler or have removed the heat exchanger cover plate, inspected the cover plate and associated gasket and then replaced them. Even if the gas company had performed the above procedures, approximately 3 years passed from the October 2014 inspection until the reported incident of October 2017. During that time, none of the recommended annual inspections and maintenance of the heat exchanger cover plate and associated gasket were performed by a qualified service technician.

The product, in the report: Gas Boiler 1/17/20015 - Original purchase date.

A routine inspection was performed 01/30/2017. The carbon monoxide testing came back with emissions of forty parts per million. The installer contacted the Manufacturer and was informed that this specific boiler was not recalled. The Manufacturer advised the consumer to install a gasket or replace the induction motor.
03/27/2017 - The gasket was replaced at the expense of the consumer. The carbon monoxide testing performed came back with emissions of twenty parts per million. The installer informed the consumer that he could replace the induction motor however there was no guarantee that this would solve the problem. The induction motor would cost the consumer approximately nine-hundred dollars. The consumer’s other option would be to replace the entire boiler.
03/28/2017 - The consumer contacted the Manufacturer and left a voice message.
The consumer is unsure if he will have the unit for at least the next thirty days.
Update to Report Number 20170328-41583-1648955
3/28/2017-The Manufacturer, Weii-Mclain, 500 Blaine Street, Michigan City, IN 46360-2388, confirmed that there are no recalls on this boiler model with this serial number.
3/29/2017-The consumer called the Manufacturer Warranty Number at 1-800-654-2109. The boiler is not under warranty for replacement parts.
4/19/2017- The installer, Reimer Home Services,255 Fire Tower Drive, Tonawanda, NV 14150 (716- 694-8524) agreed to install a new inducer motor at dealer cost, approximately $500, rather than the retail cost.
4/26/2017 -New inducer motor installed. CO monitor recorded zero CO levels during unit operation.
Cost of inducer motor to consumer was $553.54 including tax plus the cost of the gasket replaced on 3/27/2017 for $164.21. Total cost was $717.75.
BOTTOM LINE- The CO leak was mainly due to the erosion of the original caulking material which is an integral part of the inducer motor. This material is found where the inducer motor exhaust connects with the venting system. Additionally, the inducer motor gasket also loses its effectiveness over time. Manufacturer has not issued any warnings to consumers that this will occur over time due to NORMAL OPERATION of the boiler. This is a critical safety issue for all users of this product and can potentially lead to CO buildup in residences.

The company’s comments, in its own words

(8/1/2017) Weil-McLain: As a follow-up to our previous comment, Weil-McLain would like to point out that this type of repair is the type that would be identified and resolved during routine preventive maintenance, as was done by the consumer’s contractor in this case on the boiler that was originally manufactured in 2003 . The User’s Information Manual for the subject boiler states that the boiler should be inspected annually by a qualified service technician. The manual also states on page 36 (copy attached): “Visually inspect entire flue gas venting system (and air piping, if installed) for blockage, deterioration or leakage. Repair any joints that show signs of leakage in accordance with vent manufacturer’s instructions. When air is ducted to boiler, verify that air inlet hose is connected and properly sealed. WARNING: Failure to inspect for the above conditions and have them repaired can result in severe personal injury or death.”

The product, in the report: Weil Mclain Ulter 2 Boiler 105

I have Weil McClain Boiler installed last year by the local Contractor Plumber. Plumber is no longer in business. I have called the Company Weil Mcclain several times requesting help with gas leak but no reply. I have filed a complaint on BBB and some one reached out to me and said that they will contact me. Its been over a Month and I have yet to hear from some one. Every time the Boiler comes on I smell Gas. So I end up turning the boiler off. Its been off for several weeks and I have not heard back from the company. Last month due to MI cold weather I turned the boiler on and the Gas smell was really bad. I end up turning it off, While I was turning it off I heard a Bang and the boiler cover come off flying, I end up walking away with Minor Injury on my leg with not major issues at all.
I need help to get my Boiler repaired. Not sure how to reach out the Company. Thanks for your time. [REDACTED]

The company’s comments, in its own words

(6/3/2016) Weil-McLain: Weil-McLain had previously advised the consumer to have his plumbing contractor diagnose the issue and call a claim into the Warranty Department to see if it was covered under warranty. This is standard company procedure under a warranty claim, as it must be handled by a licensed contractor and not the consumer. Unfortunately, the contractor who installed the boiler is no longer in business and the consumer is working with a different contractor to identify the issues with the boiler who did not install it.
After receipt of this complaint, Weil-McLain followed up with the consumer again to advise him how his warranty claim should be handled, at which time he asked that a company representative meet with him and his contractor about the issues he has been experiencing with his boiler. A Weil-McLain representative in the area is in the process of contacting the consumer and working with him to resolve the issues. At this time, we do not have enough information to determine if the issues are installation-related or product-related, but hope to learn more after meeting with the consumer and/or his contractor.

The company’s comments, in its own words

(1/6/2014) Weil-McLain: In response to concerns posted by homeowner, Weil-McLain contacted both the contractor and the homeowner to learn more about the boiler and the homeowner’s concerns. The contractor advised that he had already replaced the heat exchanger on the homeowner’s Weil-McLain boiler under warranty. In the process, the contractor found no evidence of CO emanating from the heat exchanger and/or boiler and confirmed with the homeowner that a nearby CO detector had not been triggered. In speaking with the homeowner, the homeowner confirmed that his CO detector had never gone off and that no CO was measured in the boiler room. Weil-McLain advised the homeowner to do regular maintenance on his boiler, including making sure the condensate drain was cleaned, cleaning out the burners and testing the pH of the water to ensure the life of his boiler. Weil-McLain also advised the homeowner that aluminum heat exchangers were not a safety issue and that he did not need to be concerned about this. Homeowner advised Weil-McLain that his concerns had been addressed and that he did not have any additional questions or concerns about his boiler.
