Gas boilers recalled over CO and fire risk, 2,261 sold

Ariston Canada and HTP have recalled residential gas boilers sold in Canada because a cracked part can let the front cover detach, posing a risk of injury or death from fire, carbon monoxide poisoning and impact, according to a Health Canada recall notice published Oct. 29.

The notice covers 2,261 units sold in Canada between May 2021 and August 2025. Another 4,726 were sold in the United States. The boilers were made in Saint John, N.B.

The recalled units are the FTVN and TFTN series, sold under the Ariston Canada name (formerly NTI Boilers), and the EFTU series sold for HTP. Models named in the notice include the FTVN150, FTVN199, TFTN150, TFTN199 and the EFTU-150WBN, EFTU-150WCN, EFTU-199WBN and EFTU-199WCN. Serial number ranges that identify affected units are listed in the notice.

Health Canada said the condensate dish inside the boiler can crack during a delayed ignition. The notice said that can cause the front cover to detach.

As of Oct. 16, the company had received two reports of incidents in Canada, including one injury, the notice said. It did not describe the injury. The notice did not name retailers or provinces where the boilers were sold.

Owners should stop using the recalled boilers and contact Ariston at 1-800-688-2575 for a free upgrade kit, the notice said. Anyone who is unsure of their boiler’s model or serial number should check the rating plate on the unit and compare it with the notice.

Gas appliances that malfunction can release carbon monoxide, which is odourless and colourless. Health Canada recommends working carbon monoxide alarms on every level of a home.

The recall comes as many households prepare heating systems for winter. Ottawa has also unveiled a heat pump rebate of up to $10,000 for homeowners, and we have a guide to energy bill grants by province. Earlier this week Health Canada also posted a recall of DREO space heaters over fire risk.
