6.2 Installation
WARNING - TO REDUCE THE RISK OF FIRE, ELECTRIC SHOCK, OR INJURY TO PERSONS, OBSERVE THE FOLLOWING:
a.) Installation work and electrical wiring must be done by qualified person(s) in accordance with all applicable codes and standards, including
b.) Sufficient air is needed for proper combustion end exhausting of gases through the flue (chimney) of fuel burning equipment to prevent back drafting. Follow the heating equipment manufacturer’s guideline and safety standards such as those published by the National Fire Protection Association (NFPA), and the American Society for Heating, Refrigeration and Air Conditioning (ASHRAE), and the local code authorities.
c.) When cutting or drilling into wall or ceiling, do not damage electrical wiring and other hidden utilities.
d.) Ducted fans must always be vented to the outdoors.
e.) If this unit is to be installed over a tub or shower, it must be marked as appropriate for the appli- cation and be connected to a GFCI (Ground Fault Circuit Interrupter) - protected branch circuit.
f.) NEVER place a switch where it can be reached from a tub or shower.
WARNING:
To reduce the risk of fire, use only metal ductwork.
The applicable regulations of the energy supply companies and the regional construction regulations must be observed when installing the hood.
The minimum distance from the worktop to the bottom edge of the wall hood is for electrical appliances 24 ´ ´ / 600 mm and for gas appliances 27 1/2 ´ ´ / 700 mm.
The wall hood was conceived for the exhaust air mode. The exhaust air can be routed into a separate exhaust air shaft or directly into the open through the outside wall.
It is not allowed to pass the exhaust air into a flue or exhaust air chimney that is in operation or into a shaft that is linked to the heating basement. Consult the chimney sweep responsible for your district whenever you wish to pass the exhaust air into a chimney that is not in operation.
During the course of planning, a chimney sweep must be consulted if a room
Adequate incoming air must be ensured if a wood, coal, gas or oil heater or an open hearth is operated in the same room as the one in which the hood is installed.
Safe operation is possible whenever the partial vacuum in the place where the firing equipment is installed does not exceed 4 Pa (0.04 mbar).
This can be achieved whenever the air needed for combustion is able to enter through openings that cannot be sealed, for example in doors, windows, incoming/exhaust air wall boxes or other technical means.
