My leg extensions arrived this morning!
The gas company is coming out to evaluate running a gas line to my patio, so I will no longer need LP tanks. Wanted to provide an update here; the burner uses high pressure and will not work with the low pressure coming out of the regulator from a gas furnace. So for me, I'm stuck using LP tanks for the burner, but my grill is hooked up.
Soon I'll get to try out my new Blichmann burner, leg extensions, 15gal Boilermaker and Hop Blocker all at once!
