SMOKE OUTLET

•The smoke outlet shown in the following figures is the best solution to ensure the discharge of smoke even when the fan

is not operational, such as for example if there is an electrical power failure.A minimum drop of 1.5 metres is required

between the T terminal on the outside of the building and the outlet at the back of the appliance, to ensure that residual

combustion smoke is discharged in the case described above (Otherwise the residues would stagnate inside the firebox

and be discharged out to the free atmosphere).

The figures below illustrate the best solution for discharging the smoke out through the roof or into the flue outlet.If you opt

to discharge the smoke out through the roof it is important to operate as shown in the figure below on the left.Insert a union

tee with inspection cap, connecting brackets suitable for the height of the flue outlet, flashing that crosses the roof and

chimney cap to protect against bad weather conditions.If you decide to use a classic masonry outlet see the diagram

below on the right. A union tee with inspection cap and suitable supporting brackets are required.If the flue

outlet is too big we recommend inserting a stainless steel or porcelain-coated steel tube with a

diameter not exceeding 150mm.Seal area where the inlet and outlet part of the smoke

exhaust meets the wall.It is strictly forbidden to apply mesh to the end of the

outlet tube , as it could cause the heater to malfunctionIf 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 firebox

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 discharge tube must be made from

suitable materials such as for example: 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.

It must be possible to inspect and remove all the smoke

tube sections for clean-out purposes.

If the side outlet is used take care not to damage the silicone

tube that connects the pressure switch.
