Type B vent pipe clearance to combustibles is:

one inch
two inches
three inches
four inches

The correct answer is: one inch

The correct clearance for Type B vent pipe to combustibles is two inches. Type B vent pipes are designed for venting gas appliances, and maintaining the proper clearance is critical for safety and to prevent potential fire hazards. This clearance helps ensure that heat generated by the vent pipe does not ignite surrounding materials. While one inch might seem sufficient, the increased clearance specified as two inches provides an added safety margin to accommodate potential heat fluctuations and to ensure compliance with building codes and manufacturer installation instructions. This adherence to clearances is vital in preventing undesirable situations, including fires or other hazards associated with improper ventilation.
