Dangers of Gas Furnaces
Gas Heater Dangers
While natural gas is the most efficient type of furnace it is not without it's drawbacks. Natural Gas has certain dangers that you must be aware of to keep you and your family safe. Take a look at the items listed below if you have or are considering a natural gas furnace.
Forced air furnaces:
A gas furnace produces certain byproducts, the character and composition of which depends on the efficiency of the furnace. A gas furnace with leaks or cracks can be dangerous as it can leak carbon monoxide into your home. This gas is virtually undetectable because it doesn't smell and you can't see it. A carbon monoxide leak can make you sick with flu-like symptoms (such as headache, nausea, vomiting, dizziness, and fatigue) or, in severe cases, lead to death.
It's important to have your gas furnace inspected once a year for any leaks through which gas could escape, as well as to make sure that the flame contains the right amounts of both gas and air. There is a safety switch and a limit switch that ensure the fan will run when the furnace is hot and that the entire unit will switch off if the flame exceeds its bounds. These features should be looked at as well during a safety check.
A ventless furnace has a switch to detect dangerous levels of carbon monoxide in the air, and this feature should be checked regularly as it is possible for it to stop working.
