What is the minimum clearance required from combustibles for a single wall furnace vent?

The minimum clearance required from combustibles for a single wall furnace vent is typically 6 inches. This requirement is specified in the National Fuel Gas Code (NFPA 54), which provides guidelines for the safe installation of venting systems for gas appliances. This clearance ensures that the heat generated by the vent does not ignite surrounding materials, thereby reducing the risk of fire hazards.

In practical applications, maintaining this clearance allows for proper airflow and heat dissipation, which is crucial for the efficient functioning of the venting system. Additionally, adhering to this requirement helps ensure compliance with safety regulations, providing peace of mind for homeowners and property inspectors alike.
