I have an older model Intertherm Furnace.. Its 30 years old.. How do I light the Pilot light?

If this is in a mobile home it is a real pain.

There is a very small spring loaded door that you have to light the pilot through.

Usually the furnace came with a long piece of wire that was curled on the end to hold a sick match. If you do not see that wire you will have to make one or use a EXTENDED service mans hand held butane lighter.

Look through that hole with a flashlight to see if you can tell where the pilot is located. Good luck.
