When you want to run the blower fan only (without heating), is there a way to have it run at a slower speed, say 100 cfm, vs the 500 cfm rate it is set at for heating (there is a higher heat speed too of around 1000+ cfm).Post created: 2013-01-04 Type of Equipment: Furnace Views: 18This question was created on the page: http://www.furnacecompare.com/furnaces/lennox/g61v.html.
