Page 5: Purpose
ACCESS BY UNATTENDED CHILDREN. The KAM electric centrifugal fan in a metal casing with an impeller diameter of 146 to 158 mm, hereinafter referred to as the fan, is a part of the fireplace heating system and is designed to transport clean air with a temperature of up to +150 °C from the space around the fireplace to various rooms through the ductwork, which increases the efficiency of the fireplace with the ventilation system of the building. -

Page 13: Mounting And Set-Up
MOUNTING AND SET-UP BEFORE MOUNTING MAKE SURE THE CASING DOES NOT CONTAIN ANY FOREIGN OBJECTS (E.G. FOIL, PAPER). WHILE INSTALLING THE UNIT ENSURE CONVENIENT ACCESS FOR SUBSEQUENT MAINTENANCE AND REPAIR. 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. - Page 14 POSSIBLE OPTIONS OF INSTALLING THE FAN AND CONNECTING IT INTO THE SYSTEM Attic. One-storey house. Attic. Two-storey house. Basement – ground floor. The fan can also be installed in a garage, bathroom, etc. FIXING FLEXIBLE AIR DUCTS TO CONNECTING ELEMENTS Slide out about 5 cm of the heat and sound insulation layer and the external contour of the duct.
- Page 15 It is most preferable to use Y-joints instead of T-joints. This will reduce the air resistance of the duct system. During installation, the air ducts should be straightened and stretched as much as possible. Do not allow duct deflection. Reduce the number of turns, this will reduce the air resistance of the duct system.

Page 16: Connection To Power Mains
The recommended rated current of the automatic circuit breaker is 1.6 А. The KAM, KAM Eco, KAM EcoDuo fans have a built-in thermostat relay, which closes the fan power circuit when the set temperature of the hot air in the fireplace is reached (the fan automatically turns on and the warm air enters the room). - Page 17 ASYNCHRONOUS ELECTRIC MOTOR STARTING METHODS There are several methods for starting asynchronous squirrel-cage electric motors. The most common methods are: direct-on-line (DOL), with a soft starter (SS) or with a frequency converter (FC). Direct-on-line starting In case of direct-on-line starting (i.e. by connecting the motor to the electric mains with a simple line contactor), the motor starting time significantly increases due to high inertia of the impeller, which, in turn, results in high in-rush starting currents in the circuit.

Let us review three variations of a heavy start: 1. The feed line performance is barely sufficient or insufficient to maintain the induced current. Typical symptoms: Upon starting the circuit breakers at the system input are tripped; the lights, certain relays and contactors go off, and the supply generator shuts down. -
Page 19: Technical Maintenance
Avoid liquid dripping on the motor and the temperature controller. In case of any problems related to the fan switching or operation, it is recommended to use a troubleshooting table to eliminate the faults.
