Repair Instruction: March 19, 2025 - Recall - Repair Instruction (.pdf)
HTP, in the course of its continuous monitoring processes to ensure the quality and safety of its products, has identified a potential safety hazard in a specific batch of ELU boilers that requires your immediate attention. In coordination with CPSC and Health Canada, a safety recall has been issued. The issue has been traced back to products manufactured from October 9th, 2024 through January 15th, 2025, impacting the following units:
ELU-150WBN 3260035C8 [242830000265 through 242850000101]
ELU-199WBN 3260036C8 [243240000051 through 250150000083]
If your boiler’s serial number falls outside the stated range, it is not impacted by this recall.
On the identified units, the studs threaded into the aluminum housing on the front of the heat exchanger (used to secure the burner door) can come loose, increasing the risk of a leak of combustion products. To date, there are no known cases of personal injury or property damage resulting from this issue. However, out of an abundance of caution, we are recalling the impacted units and will be sending out Repair Kits for units already installed. For impacted units distributed to our wholesalers: we have arranged for all remaining stock to be returned to HTP for rework.
