Type C43x (concentric flue system)

Several heat sources draw combustion air from the outside through
the annular gap of the room sealed balanced flue system and expel
flue  gas  to  the  outside  via  the  roof,  through  a  moisture-resistant
internal pipe.

The multi-served chimney is a system that is part of the building and
has a separate CE marking. The connection between the boiler and
the  shaft  and,  the  connection  between  the  boiler  and  the  air  intake
system must be obtained via Daikin.

Maximum  allowable  length  of  the  flue  duct  up  to  common
chimney is 3  1 60/100 90° elbow.

In C43x type units, condensate flow into the unit is not allowed.

Type C63x (concentric flue system)

To  install  the  boiler  as  a  C63x  option  the  following  data  must  be
used  to  determine  the  correct  diameters  and  lengths  of  the  flue
system.

For D2TND*

▪ Nominal combustion products temperature: 77°C

▪ Combustion products mass flow rate: 10.75 g/s

▪ Overheat combustion products temperature: 90°C

▪ Minimum combustion products temperature: 20°C

▪ Maximum  allowable  pressure  difference  between  combustion  air

inlet and flue gas outlet (including wind pressures): 100 Pa

For D2CND*

▪ Nominal combustion products temperature: 93°C

▪ Combustion products mass flow rate: 11.48 g/s

▪ Overheat combustion products temperature: 100°C

▪ Minimum combustion products temperature: 20°C

▪ Maximum  allowable  pressure  difference  between  combustion  air

inlet and flue gas outlet (including wind pressures): 125 Pa

For D2CND* and D2TND*

▪ Minimum combustion products mass flow rate: 1.32 g/s

▪ CO

2

 content at nominal heat input: 9.0%

▪ Maximum allowable draught: 200 Pa

▪ The  boiler  must  be  connected  to  a  system  with  the  following

characteristics: T120 P1 W

▪ Maximum allowable temperature of combustion air: 50°C

▪ Maximum  allowable  recirculation  rate  under  wind  conditions  is

10%

▪ The  terminals  for  the  supply  of  combustion  air  and  for  the

evacuation  of  combustion  products  shall  not  be  installed  on
opposite walls of the building.

▪ Condensate flow into the unit is allowed.

Type C53x (twin pipes flue system)

Air  supply  and  flue  gas  discharge  from  /  to  atmosphere  in  areas  of
different pressure. The boiler draws combustion air from outside via
a horizontal pipe fitted to the external wall and expels flue gas to the
outside via the roof.

The terminals for the supply of combustion air and for the evacuation
of combustion products shall not be installed on opposite walls of the
building.
