What type of connectors should be used for appliances installed in attics or crawl spaces?

For appliances installed in attics or crawl spaces, it is important to use Type L or factory-built chimney connectors. These connectors are specifically designed to handle the conditions commonly found in such spaces, which may have increased risks of heat and flue gas buildup. Type L connectors are insulated and provide better protection against flue gas leakage, ensuring that the exhaust from the appliance safely exits the building.

Their design also considers the structural and thermal aspects necessary for safe installation in confined spaces, helping to prevent potential fire hazards. By utilizing Type L or factory-built chimney connectors, you ensure compliance with safety codes and regulations established for the safe operation of heating appliances. This option is preferred over other types of connectors which may not provide the same level of safety and efficiency in these environments.
