This flue system kit is designed for installations where the air intake position
is different than the flue duct exit point. The kit comprises of a twin adaptor
from which the air intake is taken from the adjacent outside wall (see
example Figure 3g) and the flue duct is routed vertically through the roof.
It has to be noted that the flue duct is under pressure when the
appliance is in operation and the duct can leak poisonous carbon
monoxide if the duct components are not correctly assembled. It is not
recommended to route the flue duct through living space areas, i.e.
bed rooms, living rooms etc.
For installation details refer to the instructions provided with the twin
flued kit.
For C53 flue systems the terminal for the supply of combustion air and
for the evacuation of combustion products shall not be installed on
opposite walls of the building.
