What is the maximum travel distance allowed for automatic shutoff exemption?

50 feet
75 feet
100 feet
150 feet

The correct answer is: 100 feet

The maximum travel distance allowed for automatic shutoff exemption being 100 feet is based on safety regulations and building codes in the HVAC industry. This requirement is put in place to ensure that individuals can quickly and safely reach an automatic shutoff mechanism in the event of an emergency or if there is a need to stop the system for any reason, like a gas leak or other hazardous situation. Having a travel distance limit of 100 feet is crucial as it balances accessibility with practicality, allowing installers to effectively design HVAC systems without compromising safety. If the distance were longer, it could hinder rapid response in emergencies, increasing the risk of accidents or delays in addressing potentially dangerous situations. As a result, the 100 feet distance is established to enhance safety protocols and ensure that all users can swiftly access an automatic shutoff in case of emergencies.
