Ajustable propane regulator

[gordon stephenson]

Hoping someone has knowledge that will help me out,
Anyway, recently built a hog roaster to be used at my daughters birthday bash,(as shown one of my previous threads)Cooking was done over hardwood logs and very successful it was but needed a lot of attention to keep the heat correct,I now have infrared gas burner that was used on natural gas and I have made some new jets to suit propane,My question is will an adjustable regulator help to turn down the heat.The reg I have states from 0-2bar, bearing in mind the fixed reg I have used to size the jets is the standard 14wg=0.505 psi. this means it will have to be capable of working below 0.505psi,Do you think this is do-able, or should I re-jet smaller and work at a higher pressure?
P.S. I'm asking for help as at the moment I have run out of propane and can't experiment at the moment,
Thanks in advance folks
Gordon,
PPS, the gas heater I have is a Schwank 43" long, 75,000 btu's input

why not just get hold of a valve and knob off an old caravan cooker or similar to incorperate into the design that way you can turn up and down with the same regulator and will not turn down so low that it will go out

Hi Snooper,
I have tried putting a valve in the line after the reg and there is a great difference with such a tiny adjustment, Ie: goes from full bore to wanting to go out with a very tiny movement.Thats why I thought maybe running at a higher pressure thro" a smaller jet would give greater control. Also the large heater I am using was only designed to work full on.
