Since your heater is electric, it will not "use up" the air, like a kerosene or propane heater that is unvented will . . .having said that the next issue you ought to worry about is how hot the thing gets, there is usually a standard warning label about which surfaces of the heater get hot and (if it is a good one) the "clearances to combustables" that it can safely operate within . . .the last issue is a watts n amps thing . .most household circuits are 15 or 20 amp, and are designed to SAFELY operate at 80% of that rating, that is a 15 amp circuit will safely run 12 amps continuously, and a 20 amp circuit will safely run 16 amps continuously . .to find out how many amps your heater is, there ought to be a label (the UL label) somewhere on it that states how many watts it uses. Dividing the watts by 120 volts will give you the amps it uses . .cut to the chase a 1920 watt heater will run continuously on a 20 amp circuit and a 1440 watt heater will run continuously on a 15 amp circuit, BUT (!!!) that is assuming there is nothing else on the circuit breaker . . . which is pretty unlikely .
Since no one wants to stick their neck in your noose, I’ll give you an opinion. You can put your fireplace anywhere you want it…provided it can be done to code. Clearances, venting, etc all have to meet building code and fire code. Make darn certain you get a permit, install to code and get inspections if you do this yourself. Better yet, hire a professional to look things over first then have them install. Make sure they are licensed. Youre playing with fire here…pun intended.
