Shutdown and start up procedure.

Sorry I don't know the model number as the house is 50 miles away from me. It is a
Goodman furnace, 2 years old, high efficiency.
I need to shut the gas off (propane) to run another line for a stove. When they installed the furnace he ran it through a few cycles to make sure the fuel lines were purged of all air. Should I turn gas supply off and run the furnace until it stops? Then just start and let run to get all air out? Thanks

You need to read what you posted. You are saying two things.

If you need to shut the LP down to connect a new appliance.... just turn the furnace off. No need to purge at the furnace. Allow the pressure out of the system and let vent naturally. After the connection is made..... the LP should be purged at the furnace by cracking the fitting open carefully.

Actually having the furnace running and shutting off the gas could cause a backfire.

Are you doing the connection ?
Be sure you are aware of what you are doing.
Check carefully for leaks.
Most gas/LP connections need to be inspected.
