Startup and configuration
The purpose of this Exodraft CFIR inline fan is to ensure safe venting for a single appliance or multiple
appliances. This can be performed via modulation, or through a single speed where modulation is not
required. This is accomplished by starting the fan when the appliance calls for heat, and stopping the fan
when the heat demand has been satisfied.
System testing
WARNING! Do not start the CFIR before it is safely mounted on the chimney stack. Beware of rotating parts.
Before any adjustments are made to the system, please follow these procedures:
Check the line voltage with the motor name plate rating.
Determine if the impeller is running free, and has not be subjected to misalignment in shipping or during
installation.
Apply power, and check that the impeller is rotating in the direction of the arrow on the side of the motor
housing. All Exodraft CFIR fans must run in the predefined direction indicated on the housing.
Switching any two phases between the fan and the frequency inverter will reverse the rotation.
Adjusting fan speed
Start all heating appliances connected to the chimney with the fan installed.
•
If operating with fixed speed, set the fan speed control or the variable frequency drive to the speed
where no spillage is experienced anywhere in the system.
•
If operating with variable speed, a modulating control is required. Please contact your Exodraft provider
for advice regarding fan controls and follow the instructions in the control’s installation manual.
Testing safety system
If a safety system is installed, please refer to the controls manual.
