FLUE SYSTEM
The appliance is a watertight premixed condensing boiler with fan upstream of the combustion chamber, equipped with a
storage tank on the back. The low temperature of the exhaust flues allows the use of plastic flue systems. The installation of the
flue systems must comply with local regulations in force.
The installation must comply also with municipal, provincial or sectoral regulations. Conveying the flue gases of more boilers
within the same flue duct is not allowed: each boiler must have its own separate exhaust duct.
The water heater is factory supplied without flue kit. All the flue kits available for this unit are listed in the following chart. Use
only the original kits (to be purchased separately depending on the type of exhaust system chosen) provided by the
manufacturer.

It is necessary to purchase special extensions (see the chart here below) to increase the flue length. The maximum allowed
extension is shown in the chart above. For each additional 90° elbow 1 meter must be subtracted from the total flue length. The
choice of a flue option rather than the other has to take into account local regulations, as well as technical considerations.
