4.3.2 Using an existing chimney as air inlet
You can connect the appliance onto an existing chimney. The existing
chimney then functions as air supply, where a flexible stainless steelliner
(to BS715) of 100 mm performs the flue function.
Requirements:
• Any existing chimney used as an air supply must only service this
appliance.
• 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.
• The minimum distance between two terminals should be at least 450
mm.
