Congratulations on purchasing the Eliminator by Nu-Air Ventilation Systems Inc.: the most
practical way to eliminate excess humidity from damp basements without contributing to
depressurization and associated furnace back drafting.
CONTENTS:
This package contains all the necessary hardware to install the Eliminator. You should have received:
The Eliminator (1)
5” Outside hoods (2)
5” flexible insulated ducting (8 ft)
Self-adhesive gasket (20 ft)
REQUIRED TOOLS:
To install the Eliminator you will need the following tools.
Reciprocating or jig saw
Caulking gun
Flexible caulking
Duct tape
Pan head wood screws and washers
Sheet rock anchors
Drill, tape measure, screwdriver, utility knife
INSTALLATION INSTRUCTIONS:
1. Determine where the eliminator will be located. It must be against an outside wall and should be near
an electrical outlet.
2. Measure the height of the room from floor to ceiling and adjust the eliminator to the room height less
8 inches. Tighten the adjusting screws on the side of the Eliminator at this height. For crawl spaces,
use only the top section raised off the floor by 2 inches.
3. Cut two pieces of gasket material equal to the height of the Eliminator. Attach to the back of the
mounting flanges. This will form an air seal against the wall.
4. Use the remaining gasket to make a seal on the bottom flange of the Eliminator.
5. Mark the center of two 5 ½” diameter holes 4” below the ceiling and no more than 54” apart. This is
where you will drill for the outside hoods. Make sure there is no plumbing, electrical wire or other
obstructions behind the wall or outside.
6. Use the hole saw and cut two holes completely through the wall.
7. Measure the amount of flex needed. Secure flex to the top collars on the Eliminator with tie wraps
supplied.
8. Run flex to the outside and cut with knife.
9. From the outside of the house, peel back 3-4” of the insulation from the flex ducting and tape the flex
to each of the outside hoods.
10. Mount the hoods to the outside wall using caulking to create a seal between the house and hood and
fasten with wood screws.
11. Stand the Eliminator against the wall where it is to be mounted. Drill a pilot hole for your sheet rock
anchors (finished wall) using the predrilled holes in the mounting flange of the Eliminator.
12. Insert the anchors and fasten the Eliminator to the wall using a washer and wood screw in each hole.
13. Plug in the Eliminator, and set the dehumidistat to the desired level: 40% –60%. recommended.
Your Eliminator will engage high speed when levels exceed the set point.
14. Turn on the Eliminator by turning the speed control clockwise until you hear a click (this is high
speed). Set the speed control to its continuous operation setting. Clockwise = lower speed. We
recommend you start out at the lowest setting and adjust based on room size and severity of the
humidity problem.
