5.9 INSTALLING A PROVEN FLOW SYSTEM
If required by local codes, a safety system can be interlocked
with the appliance(s) to prove fan operation. The safety
system could utilize a Proven Draft Switch (PDS), a thermal
switch, a ow switch or a sail switch. The device must be
interlocked with the appliance(s) so it shuts down in case of
fan failure or power failure.
Please refer to the PDS Installation Manual for wiring
instructions.
If the installation includes a MEC24 Exhaust Control or
EBC 30/31 Modulating Pressure Fan Control, a PDS is not
required as the function is integrated into the control.
For more information about alternative safety system, please
consult ENERVEX.

EDrive E3 controlled by an EBC 24 or EBS 31 Modulating
