There is an extra strong fuel smell outside of the unit as well.

Can anyone assist in diagnosing?

Thanks!!

If you're smelling raw, unburned propane, turn it off and take the rig/questions to someone that knows what they're doing so they can do a hands-on diagnosis of its source/cause.

And sooner rather than later!
