Every line below is in CPSC’s own words, with its source beside it.

What’s wrong with it?

A problem with the boiler’s ignition due to insufficient output voltage from the boiler’s transformer can damage the boiler’s venting. This can result in leaking flue gases, posing a risk of carbon monoxide poisoning to consumers.
