Convert Natural to Propane

Dearborne Space Heater Model DRC-20B 1 N Serial # 0000769314 Type of control -20000 BTU/HR
I finally found parts to convert it to Propane. I was sold Main Valve and Injector. Is injector what used to be called a jet or orifice? The "injector" has 56 stamped on it. It is screwed into the main valve. I was told several years ago that the orifice could not be switched out for a propane one.

How does one determine what size Injector is needed for 20'000 BTU/HR running propane?

Any repair manuals for Dearborne space heaters?

Any advice about swapping out the new valve? I have sprayed penetrating fluid on all the NPT connections as I do not want to break anything while trying to take the assembly apart.

Is this a vent-free type heater ?
If it is...... I would highly recommend not converting it to a different fuel.
You have no way of knowing if it's burning properly and producing minimum CO.
