•
A chimney that has previously been used for solid fuel must be swept before use.
•
The existing chimney needs to be airtight.
•
The existing chimney needs to have an opening of min. 150 x 150 mm.
•
The chimney needs to be intact and well looked after.
•
Use the adjustable roof-mounted-terminal especially made for this, and the
chimney connection set.
