WHILE INSTALLING THE UNIT ENSURE CONVENIENT ACCESS FOR SUBSEQUENT
MAINTENANCE AND REPAIR.
BEFORE MOUNTING MAKE SURE THE CASING DOES NOT CONTAIN ANY FOREIGN
OBJECTS (E.G. FOIL, PAPER).
MOUNTING AND SET-UP
After unpacking the fan make sure of no damages in the power supply line and no cuts and crack in the cable insulation, check the fan
casing for no hollows and other distortions. The impeller shall have smooth rotation and be not in contact with the inlet flange and the
casing.
Follow the general and special safety regulations during the preparation of the fan for operation and during its operation.
The fan must be grounded.
The starting equipment should be installed in places that allow observing the operation of the fan during start-up.
Depending on the model, the fan is mounted vertically or horizontally on a flat surface.
During installation, provide free air access to cool the fan motor.
Install the fan on the mineral wool layer and the rigid fire-resisting plate (gypsum board 0.5x0.5 m) to reduce vibration.
Keep the minimum distance of 1.5 m from the fan to the heating source and the minimum distance of 0.5 m from the fan casing to the
neighbouring objects.
Install the required amount of the decompression grilles in the fireplace hood, intake and air distribution ducts and fix them with the
clamps.
The air ducts should be insulated with mineral wool.
The intake air duct should be installed 10-20 cm below the decompression grilles.
Air flow direction must be in compliance with the direction of the arrow on the fan casing.
For fans with a backdraft damper, adjust the position of the gravity damper according to the direction of the arrows (the damper must
be installed horizontally).
The damper protects the system and the fan from overheating when the fireplace is running and the fan is switched off.
Set the fan switching on temperature with the temperature control knob (temperature adjustment range – from 0 °C to +90 °C).
