Pre-Installation
NOTICE:
Risk of damage to the appliance or flue.
▶ Read all Pre-Installation sections.
▶ Ensure all requirements are met before using the appliance or flue
installation.
Flue gases have a tendency to plume and in certain weather conditions a
white plume of condensation may be discharged from the flue outlet.
Where this could cause a nuisance, for example near security lighting, an
alternate flue position should be found.
The flue terminal positions must also follow those stated in the relevant
appliance installation manual.
For information regarding installation clearances please refer to the
appliance installation manual.
