Each of the fan blades in the squirrel cage will have a scoop like shape to them. This scoop is what collects the air and throws it out of the blower housing. So this scoop should be the leading edge if the fan is turning in the proper direction.

When looking to replace your home furnace you should get no less than three quotes or estimates. That way you can choose the one that best fits your home needs and financial needs.
Yes, you can melt the heat exchanger and start a fire that way
Impossible to answer. You need to have a Hvac pro, furnace man, do a heat calculation of you home and see if the BTU rating of your house matches the furnace supplied in it. Now even with a computer generated heat calc, there are way to many things in the home to come up with a perfect answer. You should not turn up and down the thermostat in your home from day to night, the walls and furniture cool and then it takes longer to get them back to temp, its better to leave it on one temp.
Turn off power at breaker. Take off doors. Remove screws from board and allow to hang out of the way. Remove screws from squirrel cage assembly and slide whole cage assembly forward out of furnace, Remove plug from blower motor (if there is one, if not it may be necessary to cut wires). With assembly on floor remove blower motor bracket screws, replace motor with OEM only, make sure it is balanced and reverse process.
The motor would not start rotating. The motor will just hum and the rotor will be stationary. If you can get the rotor to start turning the motor will still run on its run winding.I have a cement mixer that has a motor with a burnt out start winding. All I have to do is turn the barrel and the motor will start turning over. Without the start winding you have a choice of which way the motor will turn. If I turn the mixer barrel the opposite direction, the barrel will turn that way until I turn the unit off.

Electromagnetism is an efficient way in which to turn a motor. It does not produce pollution and it is otherwise environmentally safe.
It doesn't matter which way the blower motor turns, it is the angle of the blades that matters.
Removal would be counterclockwise.
An electric home furnace is in the neighbourhood of 10 kW to 50 kW depending on the square foot area of the home. A 10 kW furnace would require a 50 amp sub feed from the main distribution panel, a 50 kW unit would require a complete 200 amp service.In colder climates the cost of operating this type of furnace would be higher. The furnace's heating elements come on in stages depending on how cold the home is on start up. As the home reaches the thermostat set point the home will be maintained by just a couple of the elements.Electric heating of the home is a very expensive way to heat, by blowing air over an element that looks like your oven element.
The best way to tow any vehicle behind any motor home is a trailer for so many reasons but two big reasons are, backing up the motor home with the towed vehicle attached and double maintenance on the towed auto plus motor home. Trust me your WAY ahead with the trailer .... PLUS, you will need a class 3 hitch installed on the back of your motor home.
