It depends on the outside temperature and the efficiency of your furnace. If it's very cold, keeping the furnace on at a lower temperature can prevent pipes from freezing and maintain a comfortable environment when you return. However, if it's milder outside, you might save energy by turning it off or setting it to a lower temperature while you're away. Consider a programmable thermostat for more convenience and efficiency.
The furnace that is working properly should cycle on and off after every 3 - 4 hours.
To turn off the furnace, locate the power switch or breaker connected to the furnace and switch it off. This will shut down the furnace and stop it from running.
To turn off the furnace in your home, locate the power switch or breaker for the furnace and switch it off. This will stop the furnace from running and producing heat.

Well, I don't mean to sound snarky, but when it doesn't work anymore! The thermostat, in its most basic form, is just a switch to turn the heater on. If the heater turns on and off like it should, it is OK. If the heater doesn't turn on, or worse yet doesn't turn off, you should look into getting a new one. Some tests you can perform: Heater doesn't turn on? Get at the wires running to the thermostat and touch the two control wires (You will have to look into the furnace documentation if you have more than two wires) together. If the furnace clicks on, it's the thermostat. If it doesn't, it's the furnace. Heater doesn't turn off? When the furnace is running disconnect one of the control wires. If the furnace shuts off it's the thermostat. If it doesn't, it's the furnace.

The furnace may turn on when the thermostat is off due to a malfunction in the thermostat or wiring, causing it to send a signal to the furnace to turn on incorrectly. It could also be due to a short circuit or a problem with the furnace itself.
A furnace should cycle on and off after every 4 hours.
Carbon will not escape with the furnace off and it will only choke you because you will be breathing it carbon not oxygen. So my advice is dont turn the furnace off
To turn on a furnace without a thermostat, locate the furnace switch on or near the unit. Flip the switch to the "on" position to start the furnace. Keep in mind that without a thermostat, you won't be able to control the temperature or set a programmed schedule for the furnace to operate.
