Why my apc ups change its polarity after mains failuer

Probably because polarity at the plug is reversed, check for that.
There is a red LED at the back of the unit, if it is lit, polarity at the plug is reversed, you will have to correct this.

Coleman furnace

Reverse polarity means the power wires coming to the furnace are connected backwards. The black wire should the hot ( 120 volt line) . The white wire should be the neutral. The green should be the ground. Check these connections and test them to make sure they are correct. You should get 120 volt reading between the black and white.120 volts between the black and green and 0 volts between the white and green. Hope this helps.

I cant be sure but usually the constant blink on some boards means reversed polarity. Check your HOT (L1 - Black) comming in to the connector box and the your NUTURAL (L3 - White) should not read any volts to ground (not more than 12 volts on an electronic VOM). If this is opposite remove power and reverse black and white wires and retry.

6 blinks

sounds to me like i wish i could find out if this is new install or if the electric has been changed recently,,,sounds like reversed polarity on the plug,,,which means the white and black wires need to be swapped. If there has not been change recently than u need to see the other post i made on goodman about the combustion fan motors and there types and fixes. But almost certain that is reversed polarity. good luck
