Installation Exhaust-air Mode Exhaust air should not be directed into a smoke or exhaust flue that is currently used for other purposes, nor into a shaft that is used for ventilating rooms in which stoves or fireplaces are also located. Exhaust air must be discharged in accordance with official and statutory regulations only (e.g. national building regulations). Local regulations must be observed when discharging air into smoke or exhaust flues that are not otherwise in use. When the extractor hood is operated in exhaust-air mode simultaneously with a different burner which also makes use of the same chimney (such as gas, oil or coal-fired heaters, continuous-flow heaters, hot-water boilers), care must be taken to ensure that there is an adequate supply of fresh air, which will be needed by the burner for combustion. Safe operation is possible provided that the underpressure in the room where the burner is installed does not exceed 4 Pa (0.04 mbar). This can be achieved if combustion air can flow through non-lockable openings, e.g. in doors, windows and via the air-intake/exhaust-air wall box or by other technical measures, such as reciprocal interlocking, etc. If the air intake is inadequate, there is a risk of carbon monoxide poisoning from combustion gases which are drawn back into the room. An air-intake/exhaust-air wall box by itself is no guarantee that the limiting value will not be exceeded. NOTE: When assessing the overall requirement, the combined ventilation system for the entire household must be taken into consideration. This rule does not apply to the use of cooking appliances, such as ranges and ovens. VTN630W and VTN1090W Integral Blower Installation Suitable for the following hood models: HPCN36WS, HPCN48WS, PH30HWS, PH36HWS, PH48HWS, PH36GWS, PH42GWS, PH48GWS, PH54GWS, PH60GWS, VCIN36GWS, VCIN42GWS, VCIN48GWS, VCIN54GWS, VCIN60GWS, HPIN42WS, HPIN54WS Integral Blower models are integrated into the ventilation hood at the time of installation. Refer to the Installation Manual for important safety instructions. Use gloves when installing blower unit. 1. The blower is attached to the hood using weld studs provided on the mounting plate. Guide the motor mounting plate over the studs. 2. Attach (4) nuts (included with hood) to the weld studs. Tighten nuts to secure the blower to the hood. 3. Connect the blower's plug connector to the connector present inside the hood. IMPORTANT SAFETY INSTRUCTIONS • The blower must be attached at least 78¾'' (200 cm) from the extractor hood. • When attaching the outer wall blower, ensure that it is accessible for maintenance and repairs. • The plug-and-socket connections of the electric cables must be located inside the building, according to local codes. • DO NOT reduce the 6'' (152 mm) diameter of the ducting connected to the extractor hood.
