          Avoid Back drafts

Care should be taken to avoid back drafting combustion appliances that are 

installed in the conditioned space. It is strongly recommended that combustion 

appliances NOT be installed in such a manner that they use room air for

combustion. Whole house fans are capable of pulling large quantities of air

from the home and  particularly if not enough windows are open.  This could 

easily back draft gas appliances located inside your home.

Look through the hole and make sure there are no kinks or twists in the 

ducting.  Pull the ceiling box down through the hole in the ceiling.  While 

holding it in place, install a 1-3/8” drywall screw through the drywall into the 

box on each side to temporarily hold the box in place.   

Remove ceiling grill and screws from its packaging.  Center the grill over the 

ceiling box.  Install the grill with the white screws provided by screwing 

 Some ceiling surfaces are uneven and 

may cause a small gap to be present.  This can easily be caulked later if 
excessive. 

Wiring Options

 

Return to the attic and go to each location.  Using the nylon straps and the pan 

head screws provided, support the duct to the framing. This will stabilize the 

entir e assembly. 

Replace any ins ulation that was removed. The installtion is now complete 

except for the electrical wiring. 

Once all of the QuietCool fans are hung, it’s time to go below and install the 

ceiling box and ceiling grill at each intake location.
