FIT PLUME MANAGEMENT COMPONENTS - (OPTIONAL) The following procedures detail the options for management of the exhaust flue gas/plume emitted from the terminal. The terminal supplied with the Easy-Flue can be altered to divert exhaust flue gas/plume at an angle. This can be achieved by simply turning the end section of the terminal to the desired angle.
