Our master bathroom is at the far end of a long 12" duct that fed 4 other outlets with the consequence that we had to run an electric heater before taking a shower. There was an auxiliary terminal on the central heating blower circuit that I was able to connect to so the Acme fan operates automatically whenever the main fan comes on. Installation time about 4 hours, just disconnected the 12" hose from the main plenum, attached the fan casing to the exposed stub with 4 self drilling screws, (check the flow direction of the fan, it is not marked) reattached the 12" hose to the fan body and wrap the whole thing with insulation. Bathroom temperatures now 10 degF higher than before with the same main thermostat setting.
