Noted poor installation of a bath fan had a few reporting errors.
 |
From below, installations seem to be tidy. The installer probably thought he had followed directions, and has probably done many similar installations.
Directions do not consider the most-common need, remodel installation through existing drywall. Here openings were enlarged, to replace silly American noise-makers. |

Begin with knowing the guts of each fan must be removed. All screws are Phillips drive. Collect four that release the lightweight cover plate. Three more are machine screws that release the motor assembly, not dropping out. |
 |
| Each fan body is pushed through from below, and is loaded against 2x3 rails, with 2 1/2" deck screws. |
 |
Complete reassembly of fans can happen now, ready for paint.
|
Foil-tape the ducts, and reset cable staples.  |
The above is an exercise in blogging, further learning what is possible with the free resources of google.com. I think this sharing of experience is a necessary investment to fight installation error, and waste of energy. I have started another blog as another way of trying this. I think an installation methods forum of some kind is needed, and will hope to at least be a contributor.

Yes, poor installation of a bath fan gets you poor performance in return. It is primarily designed to eliminate moisture and unpleasant odor in the room. Where was it located, by the way? Mine was between the shower and the toilet. Our contractor said it would give the highest efficiency there.

More often than not, we are dealing with replacement, where we are inclined to accept the found location. Panasonic fans here are 10.5" square, usually larger than an old noisemaker, and some logical shifting will be done. I think a center of the ceiling usually is best, with only lights getting "aimed."
