Connection with coaxial pipes
fig. 10 - Examples of connection with coaxial pipes (
= Air /
= Fumes)
For the coaxial connection, fit one of the following starting accessories on the appliance. For the wall drilling measure-
ments refer to sec. 4.1. Any horizontal sections of the flue must be kept sloping slightly towards the boiler, to prevent
any condensate from flowing towards the outside and causing dripping.
fig. 11 - Starting accessories for coaxial ducts
Before carrying out installation, check with the table 1 that the maximum permissible length is not exceeded, taking into
consideration that every coaxial bend gives rise to the reduction given in the table. For example, a Ø 60/100 duct com-
prising one 90° bend + 1 horizontal metre has a total equivalent length of 2 metres.
