Conduit configuration & assembly instructions
WARNING : THE USE OF INSULATED DUCTING IS PROHIBITED
The configuration of the ductwork system will have a direct effect on the capacity of the
blower to distribute the warm 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 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 the ductwork.
The use of an airflow damper or damper blade(s) is highly recommended in each conduit leading to
an air outlet in order to balance the airflow in the system.
The ductwork should always be secured to reduce vibration noise.
The ductwork should always have a positive slope towards each air outlet for good gravity airflow.
The air registers should always be made of metal.
Attach each section of ductwork with at least 3 self drilling screws.
Reducing deviations in the system will result in a better airflow to the air outlets.
