1. Product information
1.1 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 uepipe. It is specically designed for applications
where reliable and ecient 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 ue gas temperatures of
(300oC) for continuous operation.
Typical uses are mechanical venting of gas-red or oil-red boilers and water heaters. The CFI is for
indoor or outdoor installation where ambient temperatures are in the range of -40 oC to 50 oC.
Construction The CFI Inline fan is an ecient, high-temperature ventilator with backward-inclined impeller
of cast aluminum. The ventilator housing is made of stainless steel (316L) and equipped with an
energy-ecient, 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 t 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 ue gases going through the Inline fan should not exceed 300 °C.
The CFI is not suitable for pulsating boilers.

3. Mechanical installation
3.1 General
WARNING
Failure to install, maintain and/or operate the exodraft CFI Inline fan in accordance with the
manufacturer’s instructions may result in conditions which can produce bodily injury and
property damage.
The CFI must be installed by a qualied installer in accordance with these instructions and all local codes.
See national legislation on distance to inammable materials.
Preferably, the CFI should be installed as close to the termination as possible. It can also be installed near the outlet of a
heating appliance in the breeching itself. In addition, it can be used for sidewall vented applications where it discharges
through a wall. A drain is provided with the CFI to be installed by the user.
The CFI is for indoor and outdoor installation. Unless installed adjacent to the wall it is discharging through, the
chimney material used on the discharge side must be airtight/pressure rated. The ue pipe must be installed and
supported according to the chimney manufacturer’s instructions and/or in accordance with all local codes.
3.2 Positioning
Acceptable fan positions are shown below in g. 2. If mounted horizontally, we recommend that the motor be
positioned to the side as shown in g. 2, position C.
The CFI must be mounted to provide clear and easy access to the motor and impeller assembly.
NOTE
*If the CFI is mounted in position B or C, a drain must be installed as described in Section 3.3.
*If the CFI is oriented as shown in position B, the resulting axial load on the bearings may shorten the
life of the motor.
WARNING
Never install the Inline fan so the motor points down. This will shorten the lifetime and cause a
risk of leakage.

3.3 Drain installation
Install the provided drain if the CFI is mounted in position B or C. The drain should be installed near the outlet of the fan
and oriented so it points toward the ground.
Fig. 3
Drain hole
To install the drain:
Use the drain as a template to drill 4 x Ø5 mm holes in each corner.
Use the 4 provided rivets to fasten the drain to the fan housing.
Using the tting as a guide, drill a Ø13 mm hole through the housing to
open the drain.
Remove burrs inside the housing to ensure the water to run freely through
the hole
3.4 Mounting of inline fan
The CFI has 4 x Ø10.5 mm mounting holes on each end
of the fan. Threaded rod or steel hangers should run
through these holes to hang the fan from the ceiling or
other support.
To prevent accidental contact with the hot surfaces the
supplied warning signs for“Hot surface” should be placed
on the cabinet. Follow supplied instruction with the
warning sign.

3.6 Vertical installation
To mount the CFI vertically, suspend the Inline fan with threaded rod. Once the position of the fan and rods is nalized,
hang 4 pieces of threaded rod through the mounting holes of the fan as shown in g. 7. (On back side of fan, run
threaded rod through both top and bottom mounting holes.) Once the Inline fan is leveled, secure the rod with lock
washers and locking hex nuts.

3.7 Horizontal installation
To mount the CFI horizontally, suspend the Inline fan with threaded rod or steel hangers. It may be necessary to cross
brace the fan from end to end to prevent side sway. Ensure the fan is level before permanently securing.

4.1 General
DANGER
Turn o electrical power before servicing. Contact with live electric components can cause
shock or death.
NOTICE
If any of the original wire supplied with the system must be replaced, use similar wire of the
same temperature rating. Otherwise, insulation may melt or degrade, exposing bare wire.
The frequency must not be set to more than 60 Hz. Max. revolutions (rpm) are described in
section 2.1.
The power supply cable must be attached rmly to avoid contact with hot housing parts.
It is recomended to install a motor over current protection device.
To regulate the CFI400 and CFI500 an exodraft inverter must be connected.
All wiring must be in compliance with the local codes.
exodraft CFI models operate at dierent voltages, please pay attention to the wiring details.
CFI300 and CFI350 oparates at 1 x 230 VAC.
CFI400 and CFI500 oparates at 3 x 230 VAC .
This is indicated by the terminal wire conguration in the motor junction box. See Section 4.2 & 4.3

Isolation switch:
In accordance with the provisions of the EU Machinery Directive* a combustion-gas fan
must always have an isolation switch tted. The isolation switch must comply with national wiring standards.
*Please refer to Machine Directive (2006/42/EF/-EEC/-EWG/-CEE) – Appendix 1item 1.6.3 “Separation of the sources of energy”
The isolation switch must be ordered separately, as it is not part of the standard exodraft chimney fan delivery.

4.4 Checking and changing rotation of CFI 400 and 500
To check the rotation of the impeller, it is necessary to see the rotation of the cooling vanes at the end of the motor
housing.
Correct rotation direction is also indicated by an arrow on the motor end cover. There are holes in the end cover that
allow you to see the cooling vanes, but it is dicult to see the rotation unless the fan is running very slowly.
It is possible for the fan to operate with improper rotation. However, the fan will only provide 25-30 % of full capacity.
Improper rotation damages the motor, and causes various electrical faults at the variable frequency converter.
Change of rotation is carried out by changing two of the wires at the frequency converter. See wiring diagram delivered
with the frequency converter.
DANGER
Turn o electrical power before servicing. Contact with live electric components can cause
shock or death.
