I recently purchased a home that has a Western Gravity Furnace (model # 8G-75, BTU input per hour 75000, BTU output 56250 per hour). Originally, the furnace would not work it had a strong pilot, but I could not get it to turn on. Upon further inspection I notice that the thermostat wires were worn and bare in areas. So I rewired and purchased a new thermostat, but still can not get the furnace to work with the thermostat. If I jump the thermostat wires the burners do ignite. So what I don't know is does this mean I have an incompatible thermostat or I do I need a new thermopile pilot generator? Thanks in advance for your help and troubleshooting.
