5. STARTUP AND CONFIGURATION
5.1 GENERAL
The purpose of this fan is to ensure safe venting for a single
or multiple appliances. This can be performed via modulation,
or through a single speed where modulation is not required.
This is accomplished by starting a chimney fan/power venter
when the appliance “calls for heat”, and stopping the fan
when the “call for heat” demand has been satisfied.
5.2 SYSTEM TESTING
1. Check the line voltage with the motor plate rating.
2. Determine if the impeller is running free, and has not
been subjected to misalignment in shipping or during
installation.
3. Apply power and check that the impeller is rotating in
the direction of the arrow on the side of the fan housing
(does not apply to IPVB 300). All IPVB fans run in a
clockwise direction when viewed from
the fanoutlet or when looking down at the motor.
4. Switching any two phases between the fan and the power
source (VFD is the power source if installed) will reverse
rotation (except on IPVB 300).
5.3 ADJUSTING FAN SPEED
Start all heating appliances connected to the chimney with
the fan installed.
1. If operating with fixed speed, set the fan speed control or
the Variable Frequency Drive to the speed where no
spoilage is experienced anywhere in the system.
2. If operating with variable speed, a modulating control
(EBC 12 or EBC 30) is required. Follow the instructions in
the control’s installation manual.
5.4 TESTING SAFETY SYSTEM
Adjust the setting of the Proven Draft Switch or other device
used.
Start the heating appliance and the fan, and make sure the
safety device is functioning. Turn the fan off. Shortly after, the
appliance should shut down.
