Any special procedure?

Are you sure it is a modified diesel?  Most propane gensets, at least for RVs, are modified gasoline engines with slightly lower KW ratings.

Propane will not boil off as well at colder temps, but a large enough tank can overcome this.

In fifty years working with thousands of gensets, I never run into a Propane Diesel one. Not saying it can not be, but they are as rare as hens teeth in my opinion.

They do convert diesels to natural gas, but I don't know about propane.

I saw several of these at the Jet propulsion Laboratory back in the seventies. They had to be started and warmed up on diesel and then switched over to run on natural gas. Probably could do the same thing on propane. These were 500KW units by the way.

Personally would stay away from propane.  While it is clean, reliable and will last a long time, you need a very large propane tank to get any kind of running time out of it.  Most that have owned them have been sorry for the amount of space that was consumed by the big tank.  Good Luck, TomC

I have an Onan 5500w LP genny that has operated as designed for me, although I do have an 86 gallon propane tank.

Years ago there was a difference in the summer/winter/northern/southern mix of propane/butane. I do not know if that is still the case or not.
If you filled up in the south in the winter time and then drove north into cold weather you would generally have problems with a propane furnace or hot water heater or genset or any other gas appliance not working properly.
In fact I recall reading years ago about a family that froze to death in their S/S because they were stuck in a snow storm in Wisconsin and they could not get their furnace to work.
