It's not a "Wave".
It's a French brand, made for RV installation. It's out of production now...
It was a real score- I bought it unused and still in the original box for $35.00!
Here's a (not very good) pic of the install...
Fortunately for me, the heater has a flat metal area for the fan to sit on and "suck up" heat for electricity production. That's important- it won't work on a heater that has insulated sides...
The fan has a bi-metallic strip that "tilts" it forward if it gets too
hot: that prevents damage to the unit, I guess. To allow that still to function, I attached it by means of a hinge at the front.
Truth be told, I was probably worrying about nothing- it's never gotten into that "danger zone".
The "shroud" (angel food cake pan
) prevents people, stuff etc from getting tangled up in the fan...
You'll notice that this fan is the two-blade model.
This model is the first of the fans Caframo produced- they were originally designed for woodstoves
I robbed this one from my house just as an experiment, which worked!
Woodstoves get hotter, however, and the hotter it is, the faster the blade turns. Caframo now produces 3-blade models specifically for gas stoves- supposedly they give peak performance at lower temps.
If this fan ever quits on me, I'm going to replace it with the 3-blade model.
