Once the ductwork is positioned, turn on the airflow to ensure it is positioned well and the bindings are secure. Some adjustment to the length may be required by putting more/less duct within the fabric cinches used to adjust the length. Turn on the heat switch, set the desired discharge temperature and adjust the airflow to maximum.
While the heat is starting to fill the structure, the operator installs duct management stands to stack the ductwork and to make it easier to access the heated areas. Doorway drapes on the top of open doorways force the colder airflow to be drawn from the room, through the structure and back to the Air Intake to be reheated. The Air Intake temperature is monitored and displayed at the Air Intake to indicate the progress of the heat treatment. The temperature rises as the returned airflow going into the Air Intake isn’t able to dissipate the heat into anything within the structure.
