Which statement correctly summarizes venting considerations for gas versus electric clothes dryers?

• A. Gas dryers must vent combustion byproducts to outdoors and maintain CO safety; electric dryers do not produce combustion byproducts but still need clean venting for efficiency.
• B. Gas dryers do not need to vent outdoors, while electric dryers require CO safety controls.
• C. Electric dryers release combustion byproducts and must vent to outdoors; gas dryers do not.
• D. Both types can vent indoors if space is well-ventilated and sealed.

Answer: (A)

Gas dryers burn fuel and generate combustion byproducts, including carbon monoxide, which must be vented outdoors to prevent dangerous buildup in living spaces. That’s why proper venting is tied to CO safety: the dryer’s exhaust path needs to reliably carry those byproducts outside and be free of blockages. Electric dryers don’t burn fuel, so they don’t produce combustion byproducts, but they still rely on a clean, unobstructed vent to remove hot, moist air and lint, which keeps drying efficient and reduces fire risk. So the statement that gas dryers must vent outdoors for combustion byproducts and CO safety, while electric dryers do not produce combustion byproducts but still need clean venting for efficiency, is the accurate summary. The other options incorrectly suggest gas dryers can vent indoors, or that electric dryers produce combustion byproducts, which can mislead about safe installation practices.
