Smile convert natrual gas to propane

The info from deerhit1 thread has been very helpful for me. I want to convert a Jotul J100 Gas Stove(1990), setup currently for natural gas, to propane. From this article, I feel I know what needs to be done: Change the main burner orphic, the pilot orphic, and flip the regulator. I would like to explain my setup and ask a couple of question, I took the stove apart last night. The gas comes in the main pipe, through the regulator, through a control valve to control the amount of heat I want, then from the control valve several gas lines come out to the burner, there are 5 lines to the burner all with orphices, there is also a pilot line. I have taken this apart and removed one of the main burner orphices as well as the pilot light orphic. From this I need to find a place to get the proper orphic. The main burner orphic has the # 99 on it (for natural gas) and the pilot has the #64 on it (for natural gas), would you be able to tell me the # that should be for propane fro these 2 orphices? The unit is a 25,000 BTU, with 5 main burner orphices; I imagine the orphic should be such they are for 5,000 BTU's each, which would give a total output of 25,000BTU's. Am I thinking about this right? As for the regulator, I have taken the screw off the back as noted, and inside there is a plastic screw with a cross slot, as if for a screw driver. I tried to remove this so that I could flip it over for propane, but it did not easily screw out. So I did not want to force it without asking about this. If you could give some guidance on this, that would be great. Once I get the 6 orphices changed, the regulator converted, I think I am set. The only possible other aspect is the control valve, I think the way the control valve works is: there are multiple settings, each setting turns on an additional main burner line. I do not know this for sure, but am guessing this is how it works. Do you think this needs to be changed for the conversion to propane? Thanks for any info you can help on.

My sheet dosen't go to that #99 But for 25K on Lp is # 53. Then when I go to pilot.That #64 nat is 3217btu so you need a # 75 for Lp at 3140 btu,.Now think about the higher# you go for is asmaller btu out put.Like a #80 for nat is 456btu out and for Lp is 1240 btu. A #41 is 22,714 Nat and 68,200 for LP

Hope it helps. Block off the regulator there for sure cause the outdoor one takes over on LP

Adjusting orifices

I am following the above mentioned instructions and am somewhat sure the oven and broiler orifices are adjustable. How do I adjust them to the proper level? The oven/range is a whirlpool with no pilot lights. Any help is greatly appriciated.
