    Concord Gas Furnace
    I have a Concord Gas Furnace Model CG90UB... it currently is wired to run the fan on low speed which I find is not adequate to move the air around the house... I would like to know how to change the fan speed to run on medium... the manual states there are four speeds... Low, Low Medium, Medium and High... also what is normally the fan speed to move the air through a 1250 sqft house... Thanks... Bert

    If you have 4 speeds there will be a tap on the blower that you can remove the medium speed wire and place it on the speed desired.
