If the smoke tube is installed in a fixed position, it is advisable to provide inspection openings for clean-out purposes especially in
the horizontal sections. See the diagram. These openings are essential to allow for the removal of ash and unburned products
which tend to accumulate along the discharge path. The appliance functions with the combustion chamber in a vacuum, while the
discharge of smoke to the flue outlet has a slight pressure, consequently it is imperative to ensure that the discharge system is
hermetically sealed. The smoke exhaust pipe must be made from suitable materials such as porcelain-coated steel tubes, and the
various fittings sealed with red silicone (resistant to 350°C). The outer casing of the tube must be made with insulating material
(mineral wool, ceramic fiber) or use pre-insulated tubing. THE FLUE OUTLET MUST BE USED ONLY FOR THE APPLIANCE. It
must be possible to inspect and remove all the smoke tube sections for clean-out purposes.
ATTENTION: if the flue outlet is not sufficiently insulated and /or if it is too long it could generate condensation.
It is mandatory to provide a condensation drain near the smoke outlet of the appliance. The appliance must
always and only be installed in a single flue outlet system dedicated exclusively to the appliance. If the
generator is connected to a non-compliant flue system the appliance could rapidly deteriorate due to an
abnormal, continuous overheating: in this case the damaged parts will not be covered by warranty. IF THE
CHIMNEY CATCHES FIRE DO NOT HESITATE TO CALL THE FIRE BRIGADE IMMEDIATELY.
