I have the Harman TLC2000 & was considering purchasing the Harman blower
fan (for $117.00) but found that I could get my regular summer fan ( http://www.laskoproducts.com/fans/model_4920.html
This link is broken, either the page no longer exists or there is some other issue like a typo.
) to work great when I adapted it to vent througb the same stove vent that the Harman blower
uses. ( in addition: it is very quiet, has 3 speeds,remote control & turn-off timer, less than 1/2 the price of the Harman blower
& is a good summer fan) There are also many other blower
fans that could be easily adapted at a fraction of the cost of the Harman blower
