There should be a label on the unit telling us what minimum and max circuit breaker is. Do you see such a label? Your unit will draw 94 amps, so 125 amp breaker will be adequate
The rule is amp draw X 1.25 so that would be 94 X 1.25 = 118
All I see on the label is mca 125 mop 125 kw 22.5 76842 BTUH
O.K. SO WAY DO MY LIGHTS DIME AS SOON AS THE FURNACE kicks on and off.
on label it also has HZ 60 VOLTS 240
