3.7 Installation

Aduro DraftOptimizer should be placed in the middle of the vent on top of the chimney. If you have a
chimney cap, it must be removed because the smoke extractor works as a rain cap. National rules of
movements on roofs must be followed.
Aduro DraftOptimizer is secured the following way:
Round vent hole:
When the vent hole is round(Ø146-200 mm), the round flange is lowered into the hole. To ensure the
flange is firmly fixed, the 6 arms are bent outwards on the lowering pipe. They must be bent so much
outwards that they fit the inner dimension of the chimney and are firmly fixed.
Square vent hole up to 240x240 mm (brick chimney):
When the vent hole is square shaped, it is necessary to replace the enclosed round flange with a
square shaped flange made for brick chimneys (must be bought separately).
Installation of square shaped flange on brick chimney:
First, dismantle the round flange which is part of the Aduro DraftOptimizer by loosening the black
engine cable from the cable holder. Turn the fastener and open the unit by tipping Aduro
DraftOptimizer backwards. Open the lowest link on the safety chain and release the chain link from the
opening in the pipe. Close the unit without turning the fastener into the locked position. Loosen the
hinge bolt by unscrewing the lock nut and pulling out the hinge bolt from the hinge eyes. The Aduro
DraftOptimizer unit can now be lifted off of the round flange and be put on the flange for the brick
chimney. Mount the long hinge bolt in the hinge eyes and mount the lock nut on the bolt. Fasten the
distance chain in the opening in the pipe of the flange and close the chain.
Close the Aduro DraftOptimizer unit and turn the fastener so the Aduro DraftOptimizer unit is locked to
the flange. Place the sealing mat above the chimney opening. Mount the flange on the concrete cover.

3.8 Electrical connection

Important! The Aduro DraftOptimizer power supply should always be connected to constant
current.
Aduro DraftOptimizer is powered by a 24 VDC low voltage EC-engine and requires no ground
connection. You are allowed to install the Aduro DraftOptimizer yourself by connecting it to an existing
socket outlet. National rules of movement on roofs must be followed.
Run the engine cable down along the chimney through the flashing or through the roof and down into
the attic where there is access to power. The cable should be fastened to the chimney. IMPORTANT!
Make sure that 0.5 m of cable can be pulled loose so the unit can be removed from the chimney
for service at a later time. If the control box and the power supply are installed outside in open
space, the parts must be placed in a waterproof installation box with at least an IP 54 protection.
Installation of engine cable for control box:
Open the lid of the control box and put the black engine cable through the opening in the side of the
box as shown in the photo. Mount the cords as described below:
