Can the space surrounding a chimney lining system or vent be used to vent other appliances?

The space surrounding a chimney lining system or vent should not be used to vent other appliances. This is due to safety and operational considerations. When a chimney is designed for a specific appliance, it is tailored to handle the type, volume, and temperature of the combustion gases produced by that appliance.

Using the same space to vent multiple appliances can lead to issues such as backdrafting, improper venting of gases, and potential overflow of toxic fumes, which creates a serious safety hazard. Each appliance should have its own dedicated venting system designed to manage its unique exhaust requirements. This regulatory standard prevents contamination of the flue gases and ensures the safe operation of all connected appliances.

Hence, the answer is false, as the chimney or vent system must be exclusively used for the appliance it was designed for, ensuring compliance with building codes and safety regulations.
