What is the minimum clearance requirement for rooftop gas-fired appliances?

The minimum clearance requirement for rooftop gas-fired appliances is essential for ensuring both safety and proper operation. The correct answer is 6 feet (2 meters). This clearance ensures adequate space for the safe venting of combustion products and minimizes the risk of fire hazards. It also allows for maintenance access without being in close proximity to the appliance, which is vital for facilitating service work and inspections.

In addition to safety, maintaining this clearance can help prevent potential interference from surrounding structures or other rooftop installations, reducing the risk of operational issues. Various regulations and standards emphasize the importance of adhering to these clearance requirements to ensure compliance and protect both personnel and property. Understanding these regulations is crucial for anyone involved in the installation or maintenance of gas-fired appliances.
