No worries on the timing, that weather is heading to the lower Midwest too. Our high is St Louis,MO Friday is to be around -2F ,,,, so yea.
Take your time.
The tipping over may be the internal gyro, our kerosene heater has one, so does the 500w 120Vac heaters we have around in the offices here at work.
IF there's an external dial , then you should be able to check the different resistances as you turn the dial, kinda like a rheostat.
