Humidex

Installation

Factors to consider

The installation must be done in the crawlspace or the lowest, dampest, coldest level of your
dwelling. Try to find an outside wall to accommodate a 6¼" hole to the exterior of the house where
no electrical wires or pipes are present Minimum distance to any source of heat should be 8 feet.
Make sure that you do not install the unit in a boiler room.
Also maximize the distance between the unit and the source of replenishment air (example: stairwell or
openings to upper level).
For Interior Wall Installation: The distance between the Humidex back and the exterior wall should
not be more than 12 feet. For this application the flex has to be replaced with rigid piping.
Optional: The bottom cap may be removed for added airflow.

Selecting the Duct Location

Now that you've decided where to install the unit, you must select a location for a 6¼" duct hole in
the outside wall. This hole is needed to pass a duct through the outside wall. Make sure that the hole
location is above ground level. Also make sure that the hole doesn't line up with a stud, electrical
wires, or pipe.

Ducting

You can duct from the back of the unit, or from the top of the unit by removing the top cover.
Duct can go through an outside wall, the floor joist or window. Duct should be vented above
ground level to the outside or below ground into a window well that is open and not sealed off to
the outdoors. The outside louver should be high enough to avoid infiltration of snow, flooding and
rodents, etc. All necessary parts and outside louvers are included.
When ducting the unit outside, no more than 3 feet of Vinyl Flex should be used. When
circumstances are that a longer span is required, rigid ducting can be used from the inside of the unit
to the wall. The rigid duct will improve the airflow to compensate for the additional distance the air
has to flow to reach the outside.
When replacing a pane for a window installation, use pressurized wood or similar water/rot proof
material. Make sure that no pipes, studs or wires are in the way. Duct has to be dedicated and not
combined with any other existing ductwork in operation. Seal well around the outside opening.
