well i just installed the furnace last week and i just started it up today to make sure everything was ok. everything on the furnace seems to function correctly but im not getting very much air flow out of the floor registers. i took the rear panel off the furnace to make sure both blowers were running and they both are. anybody else have this problem with these furnaces? i do have the cold air return hooked up to the furnace. i also have a backdraft damper installed so it doesnt blow air into my electric furnace. my electric furnace has a 1400 cfm blower and it just blasts the air out of the registers, you can actually stand beside the register on the floor and feel the air hitting your face. when the 6220 is running you can barely feel the air on your hand right against the register. the 6220 has twin 500 cfm blowers so im not sure whats going on. i was just getting ready to go buy 3 tons of pellets today but i dont want to waste any more money if i cant get this to work any better. any help would be greatly appreciated. thanks
