A properly running furnace should not produce significant levels of carbon monoxide; however, a cracked or leaking heat exchanger can create a safety hazard.
What are the dangers correlated with a cracked heat exchanger?
A cracked heat exchanger could permit exhaust gas from the furnace to pollute the household air with exhaust gases 包括一氧化碳. 为了让这一切发生, the furnace must be emitting high levels of carbon monoxide and the exhaust gas must be joining with the household air.
