I'm busy working out how to automate my single tier direct-fire recirc sanke mash tun.
Initially I planned on simply using a furnace valve with LP conversion, rigged it all up, then noticed that it couldn't handle the 10 PSI needed to fire the standard 55,000 BTU burners I'm using. So I hunted around, kladue filled in a key gap, and I eventually figured out why people on this site are all using the STC/ASCO valves with seperate pilot valves and so on...
...so now I'm wondering if I should go low pressure burner and regulator (Regulates to 11" W.C. (.4 PSI)) to match the furnace valve, or go to valves that can handle the higher PSI.
I think cost-wise it would sort of be a wash given that I can get cheap made-in-china burners for 21 bucks through topfoodservice.com and save the epicness of sourcing all new valve systems (with seperate pilot valves and all that added expense).
Any thoughts on this?
Will a jet burner rated for LP work through a furnace valve with LP conversion if I hook up a low pressure regulator after the 10 PSI regulator on the portable propane tank?
Can LP actually produce enough BTU's to satisfy?
Or for that matter I could run both - plumb the low pressure regulator after the 10 PSI manifold, before the furnace valve and low pressure burner - leaving the high pressure burners free to run amok at 10 PSI..
