The minimum clearance required between a wood stove single wall vent connector and combustible materials is 18 inches. This requirement is established to ensure safety and reduce the risk of fire hazards. Wood stoves generate significant amounts of heat, especially during operation, and maintaining this clearance prevents the heat from igniting nearby combustible materials such as wood, paper, or textiles.

This standard is based on fire safety codes and guidelines that are designed to protect both the stove's installation and the overall safety of the home. Adhering to this distance helps create a safe environment by preventing excessive heat build-up around the vent connector, which could otherwise lead to ignition.

Other options present distances that exceed the minimum requirement, which could also be seen in certain local codes or specific circumstances, but the universally recognized standard for a single wall vent connector is indeed 18 inches. Thus, also keeping in mind any additional local amendments or codes that may further specify or require different clearances is a good practice.
