The total area of secondary duct outlets must be equal or slightly less than the total area of
the outlets used on the distribution plenum (B).
Example of surface calculation according to the number
of outlets used in the plenum:
Diameter of plenum
outlet (in)
Surface of plenum
outlet (in
2
)
Number of outlets on
the plenum
Total surface of
plenum outlets used
(in
2
)
6 28 6 170
The acceptable total area of secondary outlets would therefore be:
Diameter of
secondary outlet (in)
Surface of
secondary outlet
(in
2
)
Number of
secondary outlets
Total surface of
secondary outlets
used (in
2
)
4 12.5 9 112.5
5 19.5 1 19.5
6 28 1 28
The total area of the secondary outlets of this system would be
acceptable because it is equal to or slightly less than the total area
of the plenum outlets.

ACORDING TO THE NATIONAL BUILDING CODE, THE BTU/H PROVIDED BY AN
OUTLET ON THE PLENUM MUST NOT EXCEED 10,250 BTU/H (3KW) AND THE HOT
AIR TEMPERATURE AT THE OUTLET OF A SECONDARY DUCT SHOULD NOT
EXCEED 158 °F (70 °C).
Once your hot air distribution system is installed, make sure to measure the static pressure
in the start-off plenum. Adjust the opening at the end of each of distribution duct with a
shutter until you get a static pressure 0.2" W.C. (50 Pa) at the plenum.
5.5 Air return system and filter
The installation of an optional air return duct connected to the blower housing will improve
the air circulation throughout the house (see Appendix 3: Optional Fresh air return
adapter (AC01392)). The use of the air filter option is also recommended. The filter
option will significantly reduce dust circulation within the hot air duct and will prevent
obstruction of the blower (see Appendix 2: Optional air filters (AC01390, AC01391)).
