Installation Process
The installer’s manual is designed for ease-of-use and clarity. Begin by mounting the adaptor entirely within a class 1 chimney.

Remember, maintaining a minimum clearance of 50mm from any combustible material is essential for safety. If in doubt, professional assistance is recommended to guarantee that the installation is up to standard.
