Conduit configuration & assembly instructions
WARNING : THE USE OF INSULATED DUCT IS PROHIBITED
The configuration of the ductwork system will have a direct effect on the capacity of the
blower to distribute the air efficiently.
The HEATFLOW S5 must never be connected to the existing ductwork system of a furnace. To
use an existing ductwork system, the furnace must be completely be removed. The HEATFLOW
S5 must be the only heating source connected to the ductwork.
Only use rigid galvanised ductwork and HVAC foil tape to seal them
The use of an airflow damper or damper blade is highly recommended in each conduit leading to an air
outlet to balance the airflow in the system.
The ductwork should always be fixed to reduce vibration noise.
The ductwork should always have a positive slope toward air outlet for good gravity airflow.
The air registers should always be in metal.
Fix each section of ductwork with at least 3 self drilling screws.
Reducing deviations in the system will result in a better airflow at air outlets.
