Topic: Indoor Grill Roasting (4 msgs / 96 lines)
1) From: Joe Screnock
Greeting to the individuals assembled together on this mailing list 
having as a unifying relationship, coffee roasting interests.  (Sure 
wish I could use the word "collective".  ;-)
I have a couple questions regarding indoor roasting.  Since I expect 
they will be separate discussions, I will post them individually.
The first has to do with converting a gas grill (Brinkman) to natural gas.
Can I simply remove the rubber-hose (LP) connections from the burner 
input and connect the natural gas line, or do I need some sort of 
natural gas regulator?  I've heard both answers.
Actually, I have heard that the regulator isn't necessary, but that it 
is beneficial.
If a regulator is needed, or even simply beneficial, where would one go 
to get one?  What specs would one look for?
Thanks for any info.
Joe

You should have a regulator for natural gas but the world will not end if you do not as thee is a 
regulator at the meter.  All of the burner orifices will have to be changed to a natural gas size.  Not a 
difficult task but as there is the potential for "problems" with any conversion of fuel types you will 
have a tough time finding anyone who will supply the needed orifices or perform the conversion.

Rich,
Just use a #49 drill on the main jets, and remove the old LP regulator.  No 
regulator required for natural gas.  I have the same grill and have done the 
research and the mod, works great.

Natural gas and propane are very close in properties.  The difference is 
very small,  for peak efficiency on N gas .. use a slightly bigger bore 
hole burner.  In other wise, take a tiny drill and enlarge the holes 
slightly, or just buy one at a hardware store for a few bucks.  Many 
also have the sheaves you can open or shut to adjust the oxygen mixing 
as well to fine tweak the flame pattern / burn efficiency.
No need for a regulator on natural gas, you are not converting a liquid 
to gas on the spot so there is no risk of sudden pressure surges, 
requiring a regulator.... so lose that.  your gas meter outside the 
house is in essence, the regulator.
Make sure though you do have a metering device, ie a low med high knob 
to adjust the flow rate though... yep a no brainer but mentioned it anyways.
also you said roasting inside,  make sure you have adequate 
ventilation.  even though many folks use gas stoves, ovens etc indoors, 
they are vented.... make sure you are flu'ing the gasses outside.
Have fun
Aaron
