Contact your nearest Heat-N-Glo dealer for part #446-511 thermocouple. If you need a thermopile thats part #2103-512. To find your nearest dealer go to www.heatnglo.com

You have a pretty old Lennox there. The G-10's went out of production many years ago....
Since you have pilot and the thermocouple was replaced you will need to check and see if there is voltage going to the gas valve. You should have 24v AC across the two wires on the gas valve when there is a call for heat. If not then the limit switch or the high limit switch are cutting the power to the gas valve. You will need to reset or replace them.
If you have power to the gas valve then you have a
faulty gas valve and will need to replace that.
It if very possible that the gas valve has failed on a furnace the age of yours. That would be my first guess. But do check for voltage before replacing it.
I hope that this will help you to solve your problem!
Thanks for using Fixya!!

The part you described is the heaters Control Valve for your Infrared Gas Heater. It is an expensive part to replace. If one is still available for your older unit.
You failed to mention where (what country you're in), but Vulcan has been popular in Australia for many years, So I'm assuming you're in Australia.
Below is a link to contact information for Vulcan in Australia, b region. Hope this helps you find a service technician.
