The blocked vent temperature switch can malfunction, causing the release of gasses

Laars Heating Systems Company of Rochester, N.H., is recalling about 570 residential atmospheric gas-fired boilers sold in the U.S. and Canada.

The blocked vent temperature switch (BVTS) can malfunction, which can cause the release of gasses, including carbon monoxide (CO), into consumers’ homes. This can increase the risk of CO poisoning.

No incidents or injuries have been reported.

This recall involves residential atmospheric gas-fired boilers manufactured from January 28, 2021, through January 12, 2022, and sold under the Laars Mini-Therm JX and Bradford White Brute Mini brand names.

A list of the recalled models and serial numbers, which can be found on the boiler rating plate on the right side of the boiler, can be viewed here.

The boilers, manufactured in the U.S., were sold at independent contractors, plumbers, and plumbing supply distributors nationwide from January 2021, through January 2022, for between $6,000 and $8,000, including installation.

What to do

Consumers should immediately contact Laars Heating Systems to arrange to have a certified technician install repairs at no cost.

Consumers who continue to use the boiler while awaiting repair should have working carbon monoxide alarms on every level of the home and outside sleeping areas. The firm is contacting all known purchasers.

Consumers may contact Laars Heating Systems toll-free at (888) 454-3223 from 8 a.m. to 5 p.m. (ET) Monday through Friday, by email at, or online for more information.
