8. Blower installation
WARNING
The blower must be positioned in a way so that the shaft of the motor is not pointing
downward.
There must be openings around the blower to ventilate the motor. DO NOT COMPLETELY ENCLOSE
THE BLOWER BETWEEN JOISTS.
The blower should be installed in a location with easy access for maintenance purposes
and where the noise will not be an annoyance.

9. Electrical wiring
WARNING
The installation of the Heatflow S5 requires a power outlet (120V). The wiring must be done
in accordance to local legislation/norms and national building code.
The wiring must only be done by a certified electrician.
The Heatflow S5 must be wired to a 120V/15 amp circuit breaker.
WARNING: Special attention must be taken to the passage of wires and should be shielded
from radiant heat. WIRES SHOULD NEVER BE IN CONTACT WITH ANY PART OF THE
SYSTEM (Stove, Heatflow S5 jacket, air conduit, pipe, etc …)
Connect the blower to the control sub-assembly (G) with a 14/2 wire and wire connectors. The
following schematic shows how:

10. Conduit configuration & assembly instructions
WARNING
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.

Instructions to balance the airflow at the different air outlets:
1. The diameter of the main conduit should be reduced to 5” (127mm) af ter 20ft(6.1m) and/or
reduced by 1 inch every 2 air outlets.
2. After the system is completely installed, put the control sub-assembly to “M” to start blower
(refer to Section 11, Operating instructions).
3. Open all dampers located in ductwork leading to an air outlet.
4. Locate the outlet with the strongest airflow (it should be the first outlet from the blower).
5. Slightly close the outlet damper and verify the airflow at each air outlet to compare their
speed. If the airflow of the strongest is still too strong, repeat this step.
6. Proceed progressively with each damper by closing them slightly and balancing each
airflow at air outlet. If at a last air outlet, it is impossible to keep a consistent airflow with
the previous air outlets, it might be an indicator that the section of the ductwork should be
reduced.
7. The damper of the furthest air outlet from the stove should stay fully open.

11. Operating instructions
WARNING
NEVER BLOCK ANY HOLES/LOUVERS ON THE HEATFLOW S5 METAL JACKET. FAILURE TO
COMPLY COULD RESULT IN FIRE, INJURY, DAMAGE TO THE STOVE, BLOWER OR AIR
DUCTWORK SYSTEM, etc..
DO NOT MODIFY THE SYSTEM. FAILURE TO COMPLY COULD RESULT IN FIRE, INJURY,
DAMAGE TO THE STOVE, BLOWER OR AIR DUCTWORK SYSTEM, etc..
ALWAYS SET THE SYSTEM TO “OFF” WHEN RELOADING THE STOVE WITH WOOD.
IMPORTANT : If the stove is new, it is normal to have an odor of smoke when lighting it for
the first time. This intitial fire(s) should always be done before connecting the air ductwork
system to the HEATFLOW S5 in order to prevent the odor of smoke from being dispersed to
all rooms having an air outlet.
1. Plug the control sub-assembly into an electrical outlet.
2. Select the desired mode with the 3 position switch located on the top of the control box behind the
HEATFLOW S5.
A- « AUTO MODE » in this position, the blower will
start and stop automatically with the temperature of
the stove.
O- « OFF MODE » in this position, the blower is
stopped immediately. It is highly recommended to
put the system in this mode when reloading the
stove with wood.
M- « MANUAL MODE » in this position, the blower
will always be energized.
3. Adjust the blower speed with the rheostat to optimise comfort at air outlet
a. Higher blower speed →Lower temperature at air outlet
b. Lower blower speed →Higher temperature at air outlet

12. Troubleshooting
Blower does not start
•Make sure the control assembly is connected
to an electrical outlet.
•Verify the switch is not in the « O » position
•Verify the rheostat is open
•Verify the electrical wiring is correct
•Sufficient wood loading
Blower starts and stops frequently
•Low quantity wood
•Blower speed is too fast
•The air ductwork system is not balanced
Temperature at air outlet is cold
•Low quantity of wood
•Blower speed is too fast
•The air ductwork system is not balanced
