Function
Use
The
exodraft
CFI Inline fan is intended for use as a true in-line draft inducer. It can be installed
in-line in the vertical or horizontal section of the fluepipe. It is specifically designed for applications
where reliable and efficient operation, low noise level, low energy consumption, variable speed
and compact design are critical.
The CFI is for use with condensing and non-condensing appliances at flue gas temperatures of
(300
o
C) for continuous operation.
Typical uses are mechanical venting of gas-fired or oil-fired boilers and water heaters. The CFI is for
indoor or outdoor installation where ambient temperatures are in the range of -40
o
C to 50
o
C.
Construction
The CFI Inline fan is an efficient, high-temperature ventilator with backward-inclined impeller
of cast aluminum. The ventilator housing is made of stainless steel (316L) and equipped with an
energy-efficient, totally enclosed, variable speed motor with sealed and permanently lubricated
bearings. The motor and impeller is a complete assembly (drive unit) that can be removed from the
fan housing without removing the fan from the stack system. The stack connections fit most com-
mercial pre-fabricated chimney systems.
Restrictions
The CFI Inline fan should only be used with appliances operating on Natural Gas, LP-Gas/Butane or
fuel oil. It should never be used with incinerators or solid-fuel burning equipment. The temperature
of the flue gases going through the Inline fan should not exceed 300 °C.
The CFI is not suitable for pulsating boilers.
