Accessories
The following criteria should be noted when planning the installation.
– The flue system inclines 2
1
⁄2" (44mm per metre) from the appliance, to
prevent condensation from dripping from the flue terminal.*
– Because the appliance operates at high efficiency a white plume
of condensation will be emitted from the terminal. Care must be
taken when selecting the flue terminal position.
