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:

Electric cookers

650 mm

Gas cookers

650 mm

Coal- and oil-fired cookers

min. 700 mm
