5. Startup and Configuration
5.1 General
The purpose of this 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 a chimney fan/power venter when the appliance calls for heat, and stopping the fan when the heat demand has been satisfied.
5.2System Testing
1.Check the line voltage with the motor name plate rating.
2.Check that the transport securing device (if applicable), holding the motor shaft and impeller in place, has been removed.
3.Determine if the impeller is running free, and has not be subjected to misalignment in shipping or during installation.
4.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 RSIB 300). All EXHAUSTO fans run in a clockwise direction when viewed from outside the door.
5.Switching any two phases between the fan and the power source (VFD is the power source if installed) will reverse rotation (except on RSIB 300)
5.3Adjusting 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 spillage is experienced anywhere in the system.
2.If operating with variable speed, a modulating control (EBC12, EBC14, or EBC30) is required. Follow the instructions in the control’s installation manual.
5.4Testing 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. After less than 2 minutes, the appliance should shut down.
