General Notes
Exhaust air mode
Note: Ventilation may not exit through an already
operational smoke or exhaust chimney, nor a duct used
for ventilating furnace installation areas.
If the ventilation is intended to pass through a smoke
▯
or exhaust chimney that is not in operation, the
responsible area heating inspector must give
approval.
If the ventilation passes through an external wall, use a
▯
telescope wall sleeve.
Ventilation line
Note: The appliance manufacturer does not assume any
warranty for complaints attributable to the pipe section.
The appliance achieves its optimum performance by
▯
means of a short, straight exhaust air pipe and as
large a pipe diameter as possible.
As a result of long rough exhaust air pipes, many pipe
▯
bends or pipe diameters that are smaller than 6"
(150 mm), the optimum extraction performance is not
achieved and fan noise is increased.
The pipes or hoses for laying the exhaust air line must
▯
consist of non-combustible material.
Round pipes
An inner diameter of 6" (150 mm), but at least 4
(120 mm), is recommended.
Flat ducts
The inner cross-section must correspond to the diameter
of the round pipes.
dia. 6" (150 mm) approx. 27
dia. 4 _ " (120 mm) approx. 26
Flat ducts should have no sharp deflections.
▯
Use sealing strip for deviating pipe diameters.
