4.3 ADDING CHIMNEY SECTIONS
Add chimney sections, according to the manufacturers installation instructions. If the chimney system passes
through an attic space a rafter radiation shield or attic insulation shield is required. The chimney must extend at
least 3ft (0.9m) above its point of contact with the roof and at least 2ft (0.6m) higher than any wall, roof or building
within 10ft (3.1m). If the chimney extends more than 5ft (1.5m) above the roof, it must be secured using a roof
brace or guide wires. A raincap must be installed to avoid internal damage and corrosion.
