Hi Everyone, I have a 2x4 flat pan on a block arch and was using a small desk fan for under grate (or is it through the grate?) air. I'd like to do something that will up the amount of air being pushed in. I'm thinking about a squirrel cage blower that I could set in front of the air intake on my arch. I'd like to power it with an extension cord and it would be nice to be able to adjust the air flow. I'd rather not spend a great deal but....Does anyone have any ideas to help me get what I want? What size blower? Motor size? Rheostat wiring? As you can see this is not my area of expertise! Any help will be appreciated. Ted
