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 80 mm)
