User manual STUV 16-IN ASSEMBLY OF A FAN

[. . . ] A fan can only be installed provided three conditions are met. 1 The combustion air feed duct is connected to the stove and draws in the air either from outside the building or from inside but at a distance that is beyond the depression area created by the fan, 2 Air inlet for the fan: the free surface area for the passage of air at grill level and the section of the duct have to be at least 320 cm2. 3 The hot air comes out of the stove's front outlet Please note: provide access for annual dust removal from the fan. [. . . ] Attach the electronic circuit under the front part of the fan access cover using 2 M4 x 8 screws with hexagonal heads [photo 3]. Put down the rear part of the access cover [photo 4]. Attach the back cover at the same time as the side parts [a] forming the mouth of the fan using the 2 M4 x 12 screws. Connection of the power supply and earth Connect the cables to the circuit; the terminal blocks can be disconnected from the electronic circuit [photo 5]. The connection indications are marked on the underside of the terminal blocks (power supply, earth, speed 1, 2, ). Connect the power supply [photo 6-a] and the earth to the circuit's metal support [photo 7]. Strip the cable with 4 wires and clean the sheath of each wire; you will see that each of the wires is numbered. Connect to the terminal block [photo 9-c] by following the indications of the wiring scheme [8]. Test the unit is working before connecting the thermal switch. If the pressure loss in the fan circuit [diagram 10] is low (A + B < 3m)*, the factory settings are correct: The "jumper" [photo 11 and diagram 12] is properly positioned (J2 side, on the left). If, on the other hand, the ducts are longer (A + B > 3m)*, the fan will require more power to overcome the pressure loss: Remove the jumper and put it onto the 2 straight pointers (C17 side). The thermal switch only allows power to the fan when the temperature of the reheated air is high enough. Therefore, when lighting, the fan will only start after a few minutes to prevent unpleasant currents of cold air. With installation on a Stûv base, attach all the cables together using the brackets provided to the right lug of the support [photos 14 and 15] to keep them away from the fan. Close the side openings using the 2 corresponding sealing plates and attach them (size 2. Attach the front part of the cover (with the electronic circuit) to the base plate [photo 2]. [. . . ] Cut it by 10 cm for the 16/68 to a length of 50cm - and by 20 cm for the 16/58 to a length of 40cm Put the metal wire into the seal to make it easier to position [photo 2]. Insert the seal behind the valve mechanism between the stove and the plate [photo 3]. Stûv reserves the right to make changes without prior notice. [. . . ]
