Type 1 and Type 2 clothes dryers shall be exhausted to the ________.

Type 1 and Type 2 clothes dryers must be exhausted to the outside to ensure safe operation and compliance with safety standards. Venting to the outdoors prevents the accumulation of harmful gases, moisture, and lint inside the living environment, which can pose serious health and fire risks. Outdoor exhaust helps in maintaining indoor air quality by removing excess heat and humidity that the dryers generate during operation.

Exhausting to the inside, basement, or ventilation shaft is not only unsafe but also can lead to increased humidity levels, mold growth, and lint buildup, which can create fire hazards or respiratory issues for occupants. Thus, the requirement for outdoor exhaust is a crucial safety measure in the design and installation of clothes dryer systems.
