The blocked vent switch (BVS) can fail to shut down the burners if the boilers are installed at altitudes above 2,000 feet and the vent system becomes blocked. In such an event, the boiler can emit excessive amounts of carbon monoxide into the building, posing a carbon monoxide (CO) poisoning hazard to consumers.
The blocked vent switch (BVS) can fail to shut down the burners if the boilers are installed at altitudes above 5,400 feet and the vent system becomes blocked. In such an event, the boiler can emit excessive amounts of carbon monoxide into the home, posing a carbon monoxide (CO) poisoning hazard to consumers.
The boiler’s flue collector can crack if exposed to a high impact event in the burner chamber, which can allow the boiler to emit carbon monoxide, posing a risk of carbon monoxide poisoning.
Delayed ignition and/or flame rollout can occur with the boilers, posing a burn hazard.
The siphon can become blocked, leading to a delayed ignition that can damage the boiler’s exhaust system, creating a carbon monoxide hazard.
A wiring malfunction can result in the burners failing to shut off, posing a fire hazard.
The U.S. Consumer Product Safety Commission (CPSC) is charged with protecting the public from unreasonable risk of injury or death associated with the use of thousands of types of consumer products. Deaths, injuries, and property damage from consumer product-related incidents cost the nation more than $1 trillion annually. CPSC's work to ensure the safety of consumer products has contributed to a decline in the rate of injuries associated with consumer products over the past 50 years.
Federal law prohibits any person from selling products subject to a Commission ordered recall or a voluntary recall undertaken in consultation with the CPSC.
