clearance between plate steel stove and LP furnace/supply

[moresnow]

Any general rule on distance between the wood stove and a LP furnace (hanging, ceiling mount style).
I stopped by a buddies place that is getting a garage remodel. When walking in the overhead door the wood stove sits against the back wall, just right of center. Up and to the right is the hanging LP furnace. I did not measure the distance between them but did notice the LP supply line attach's to the LP furnace on the bottom, and nearest side to the wood burner.
Looked sketchy to me at best! Any direction or advice would be apreciated. Thanks

when our stove was installed in the basement our code enforcer checked measurements to make sure it was 10 feet from the fuel drum. i don't know if that was NFPA or local though.
