no because you need a fork an a knife to eat your cat
yes.
Pilot light would work but the main burner would not as the thermocouple proves that there is a pilot light to fire. The main gas valve would not open
My parents did it with existing ductwork.
the filter on a central unit is the same as the furnace filter usually located in duct work directly beside furnace
The gas valve is an electrically powered device that is wired at the end of a series circuit so that it can only be energized (open) if all of the safety switches upstream in the circuit are closed and the pilot flame is lit on a standing pilot furnace.
It could be different for every house.A side note: I'm taking that you mean where is the pilot light located in side your furnace? Depending on the of your furnace it's very possible your furnace does not have a pilot light, in fact it may have an ignition system with a flame management sensor. Try this; turn off the system with the main electrical cutoff switch, wait for about 2 minuets, turn on the switch raise the temperature of the thermostat high enough for the furnace to come on, this should work if it does not try one more time. If that fails call a HVAC & R technician.
The thermocouple tells the gas valve to supply gas to the burners. If the thermocouple is bad then the furnace will not work or the pilot will not stay lit. A properly working one will have a reading of at least 12 milliamps.
It takes about 5 to 10 men to work a steamboat furnace
If you have hot water heat or steam heat, it will still work. Gas or electric heat has nothing to do with the water system.
Due to the rising costs of oil, most people are struggling to deal with their rising heating and cooling prices. While central heating prices are much higher than they have been in the past, there are plenty of ways to reduce your central heating costs. One of the best ways to reduce your central heating costs would be to get a new furnace. Old furnaces tend to have much lower efficiency than a new one does. Because of this, if you switch to a new furnace, your furnace will need to work much less to keep your home warm. This will then reduce your central heating costs.
An example of work of a pilot: Someone who flies an airplane
My wall furnace has an overheat safety switch. It's up near the top on the side of the unit. If the exhaust vent gets too hot, it will trip the switch off. I use a small screwdriver to reset the switch by pushing the little red button. The switch when activated shuts the thermostat to off. By resetting it, the thermostat will now work.
