There must be nolong horizontal sections or abrupt deviations along its length (see fig. 1-2).• For type B open combustion circuit boilers;• connect the boiler to the chimney using a ∅ 130 link.• For type C12 sealed combustion circuit boilers;• KIT A - COAXIAL EXHAUST connect using the ∅ 100 - 60 double elbow and 2 coaxial pipes; ∅ 60 for EXHAUST ofcombustion gasses - ∅ 100 for air INTAKE.• For type C32 sealed combustion circuit boilers;• KIT B – TWIN PIPE SYSTEM connect using 2 sections with a ∅ 80 elbow for the EXHAUST of combustion gasses - ∅ 80for air INTAKE.N.B.: FLUE KITS are supplied in a separate box.Wall Hung Boiler with D.H.W.
