Installation Notes—Room-to-Room-Direct Flow Application
– refer to sketch for clarification
•Do not install in a fire rated wall or ceiling. Refer to your local building code.
•Determine wall location making sure there are no obstructions inside the stud wall.
•Determine if the fan unit is to be in an upper or lower wall location
•It is preferred to locate the Geni 4x near an electrical wall outlet.
•Determine the center between the studs in the wall and mark the 4”x10” location using the level.
Using the 4 ½ ” x 10 ¼ ” template mark the wall opening. NOTE: The location should be at least
6” above floor or 6” below the ceiling whichever the case may be.
•Using the dry wall saw cut the opening in the dry wall.
•Slide the inner duct through the wall and locate at the opposite dry wall. Mark the opposite wall
(4”x10” opening) using the inner duct as a guide. Drill holes in the four corners of the marked
area. This will locate the duct at the opposite wall.
•Locate the opening on the opposite wall, align the 4 ½ ” x 10 ¼ ” template and mark the opening.
Using the dry wall saw cut the opening in the dry wall.
•Install the inner and outer duct and adjust to the correct spacing. Trim to the correct spacing with
utility knife. NOTE: It may not be necessary to use both the inner and outer ducts if the spacing is
narrow. One duct will interface with both the fan and grille
•On the back of the Geni 4x locate the mounting points on the back of the fan cover and drill out
with a 3/16” drill bit. Refer to Geni 4x instruction sheet.
•With inner and outer duct installed (or using only one duct sleeve) slide the Geni 4x fan into place
and attach with screws provided.

•Do not install in a fire rated wall or ceiling. Refer to your local building code.
•Determine wall location making sure there are no obstructions inside the stud wall
•Determine if the discharge is to be located in a high or low position. Typical installations will have
the discharge fan low with the intake grille high
•It is preferred to locate the Geni 4x near an electrical wall outlet.
•Determine the center between the studs in the wall and mark the 4”x10” location using the level.
NOTE: The location should be at least 6” below the ceiling or 6” above the floor. Using the 4 ½ ”
x 10 ¼ ” template, mark the opening. Using the dry wall saw cut the opening in the dry wall.
•For installation of the grille, determine the location for the opening on the opposite wall centering
between the studs in the wall. NOTE: The location should be at least 6” below the ceiling or 6”
above the floor. Ensure the grille location in the same stud opening as the fan. Using the 4 ½ ” x
10 ¼ ” template, mark the opening. Using the dry wall saw cut the opening in the dry wall.
•To optimize the air flow from the grille to the Geni 4x fan discharge, install the outer duct at the
grille side and cut an opening directed toward the fan. Using the inner duct, install at the Geni 4x
fan location and cut an opening directed toward the grille. Using the utility knife adjust the length
of each duct to fit in the stud wall opening-see included sketch for clarification.
•On the back of the Geni 4x locate the mounting points on the back of the fan cover and drill out
with a 3/16” drill bit. Refer to Geni 4x instruction sheet.
•With inner duct installed, slide the Geni 4x fan into place and attach with screws provided.
•Using the outer duct install the grille on the opposite side of the wall using the screws provided.

•Do not install in a fire rated wall or ceiling. Refer to your local building code.
•Determine location making sure there are no obstructions inside the floor joist.
•Decide if you want a down flow or up flow discharge.
•It is preferred to locate the Geni 4x near an electrical wall outlet.
•You will need to locate the air flow channel from the ceiling to the floor. Mark the ceiling at the
desired location. Cut a small hole in the ceiling which will allow you to inspect inside the joist
area and to locate the floor above.
•Locate the ceiling opening in the floor above. HINT: You can drill a small hole up through the
floor and using a rod or long screw driver, push up through the sub floor and carpeting in order to
locate the lower ceiling position opening.
•After the ceiling and floor locations have been established, use the 4 ½ ” x 10 ¼ ” template to
mark the opening in the ceiling directly below the floor location. . Using the dry wall saw cut the
opening in the dry wall.
•Slide the outer duct through the ceiling opening and locate at the bottom of the sub floor. Mark
under the sub floor the 4”x10” opening using the outer duct as a guide. Drill holes in the four
corners of the marked area. This will locate the duct at the floor level.
•At the floor level, place the 4 ½ ” x 10 ¼ ” template over the four drilled holes and mark where the
opening is to be cut. NOTE: If necessary, remove carpeting.
•With the opening properly marked, cut the opening in the floor. This opening should be aligned
with the ceiling opening below.
•Slide the inner duct in the floor opening and place the Geni 4x fan in the inner duct.
•At the ceiling location, slide the outer duct into the inner duct from the floor above. Using the utility
knife, cut the ducts to properly mate from the floor to the ceiling. Place the grille over the opening
and attach with the two screws provided.
NOTE: If the Geni 4x is installed in the ceiling, you will need to purchase a floor register for the
floor opening.—do not use the grille as a floor register.
