The manual says to match the blower speed to thermostat setting. High to High, Low to Low and so on.
Why is this?

I find that the fan has the ability to dissipate enough heat that it can reduce your catalyst overall operating temperature. If for instance your running low, but you kick the fan on high for an extended period of time, you could potentially stall the catalyst before all the fuel in the box has had a chance to burn up.
A few weeks ago, I just about did this myself. I cranked the thermostat down about as low as I go and left the fan running. I caught what I did about the time I saw my flue temps go into the 200 -250 range which is not normal for me during the burning of a full load. I actually had to open my bypass and open things up as if I was reloading to get a little kindling fire started to re-ignite my load.
I normally would not run my fan unless my stove was hot enough that I was wanting to dissipate some temps because things were getting really hot. If you're going to run low, your fan should be low enough that that it does not "over cool" your system.

Note that there are two settings that have the same stove output. A high thermostat setting with low fan setting or a low thermostat setting with high fan setting. I choose a higher thermostat and no fans because I like the silence but some folks feel that the fans help the warm air "move" better for more even household temperatures.
