NOTICE
The boiler manufacturer cannot be held responsible for atmospheric conditions
when siting flue terminals.
CAUTION
Once the flue system has been installed and the appliance commissioned, the
installer should observe the plume direction. Particular attention should be drawn to
plume vapour reentering the gas boiler via the air intake. If this occurs, it is highly
possible the flue is fitted with a negative pressure area and therefore a plume
management kit MUST be fitted.
Condensation may occur on the outside of the pipe material when the material
temperature is low and the environment temperature is high with a high humidity.
Use 10 mm damp-proof insulation material when there is a risk of condensation.
The 60/100 mm horizontal flue system may be extended up to a maximum length
as specified in the table indicating the maximum pipe lengths. Calculate the
equivalent length according to the specifications in this manual.
