Converting non-convertable Thermador range to Propane

7 posts in this topic

Hi, all.

 

I recently got a second-hand Thermador range (model PGR364GDZS [the model number for the propane version is PGR364GDLP]) which I need to convert from NG to LP. Except suposedly it's non-convertable, comes from the factory one way or the other. The best info I've been able to find on this issue has been from this forum, in this 2011 thread.  http://appliantology.org/topic/34848-propane-conversion-thermador-pgr366zs01/

 

I contacted a local repair guy who has experience with Thermadors, and he called a Thermador engineer, who says that these ranges are not convertable because it is too hard to get to the burner orifices to change them. Can't be done without a whole lot of tearing apart, he says.

 

I'm willing to do "a whole lot of tearing apart" if necessary to make this work; I really love the range. What I'm not clear on is whether this is just a big pain in the ass, or really nearly impossible as claimed. Has anyone opened one of these things up?

Thanks in advance for any advice you can give me.

 

**I am aware that this is super-duper horrible dangerous and I will probably kill myself and my family, and cause the colapse of western civilizaion by messing with a gas appliance in a way the manufacturer disaproves of.  I'm willing to take the risk.

Well, that was easier than advertised. We tore the cook top apart tonight. The gas regulator took about 5 seconds to switch to propane, and the burner orifices were easy to access and dissemble.

 

For future google-ers, the part you need for the burners is Part number: AP3782890

Part number: AP3782890

 

The regulator needs the brass nut removed, then there is a plastic part stuck to it. Pull the plastic off and turn it around, put back together. 

 

We don't have the parts yet, so things have not been reassembled, but I will report back when it's done.

Two of the orifices were backordered, but we got the other two, and things are running nicely.

What color is the flame from the burners? Orange? Or blue?

LP orifice outlet holes are smaller than NG.

You can peen down the holes to close them to the right size.

The flames are a nice consistent blue. We are going to have to re-drill the orifices for the oven, griddle, and broilers because the parts aren't available (at least that I can find.)

Getting the orifices out of the broilers was the biggest challenge, we had to go in through the back of the range, and it was kind of a pain. Took probably an hour.
