Chimney Flue Connection - Baxi 45 HTE Installation, Operation And Maintenance Manual

Connect the boiler to the flue using a pipe made of stainless steel or plastic material with an internal diameter
of 100 mm, capable of resisting normal mechanical stresses over time, as well as high temperatures (<120°C)
and the chemical effects of fuel gases and their condensates.
Insert the flue-gas union and fasten the connector to the flue-gas thermostat before hooking up to
the flue.
Whenever possible use a flue connection that can be disconnected for maintenance.
Important! horizontal flue sections must have a minimum slope of 3° towards the boiler.
Flue accessories made of plastic material for cascade or single installations are available (diameter 110 mm)

Important! If the exhaust flue is longer than 10 metres, certain parameters on the electronic control card have
