In doubtful cases, please seek the advice and consent of the'
competent
area chimney-eweBp or the local building auth-
orities.
Since, in spaces without fireplace, the rule is: "Supply air
opening as large as exhaust air opening", the efficiency of the
exhaust air device may be MERIR by the greater opening of
500 — 600 cm?.
Operation of the hood as a return air hood in such circumstan-
ces is safe and is not subject to the regulations noted above.
Operation of the fume extractor hood in return air mode is
optimum only when the following are ensured:
short, straight exhaust air runs
as few pipe bends as possible
running of pipes in flat arcs, not in acute angles
as large as possible pipe diameters (basically min. 120 mm
dia. for two-motor hoods).
Failure to observe these principles is inevitably associated
with power losses and increased operating noise.
During installation of the fume extractor hood, the following
minimum
distances from the upper edge of the hob to the
lower edge of the fume extractor hood must be complied with:
