Propane gas is heavier than natural gas. It will take a while for the propane to travel the lines to the stove. Give it up to a minute. Hold a flame next to the burner and monitor.

Quite familiar with the need to wait for gas flow. In this case, you could wait all day and nuttin. Not even a slight whiff of gas or sound of air. Confident that the regulator is shutting off gas flow entirely at high altitude. At lower elevations, stove works fine!

I am also wondering whether any of this is influenced by the orifice size in the burners. Though I don't know, I am guessing that this too can affect the impact of atmospheric pressure on the regulator. Got the new assembly today, so we will soon be able to do a partial comparison. But complete comparison will have to await another outing above 4500 feet. It uses the same R60 regulator. Can only hope some changes have been made.

I'm not sure if the burner orifice size affects gas getting to the burners. Once the gas made it to the burner, then how many BTU's of heat comes out at wide open control knob setting, then yes the orifice size would affect this. The gas control knob for each burner is a variable orifice as it relates to the amount of gas flowing to the burner. Since you can adjust the burner knob from closed all the way to wide open, one would think if orifice size was an effect, that some level of gas would come out of the burner and light or at least smell, throughout the range of the turning the control knob changing the control valve opening.

You have the assembly, OK curious minds need to know, any chance of a few pics of the old next to the new some time? And they are using the same R60 regulator?? OK, curiosity is at an all time high now. [emoticon]

Hope the new assembly works.

Yes, I will post some side by side pics.once the old one is pulled out. But a real test will require a return to high altitude. Though Lookout pass is nearby at 4700 feet. Lola pass is a bit further at 5300 feet. Yes, the R60 regulator is on the new part, but it’s mounting tube is continuous with the whole assembly. On the originals, the regulator is on a long tube that then attaches to the gas manifold. BTW I found that regulator is or was used on a Suburban stove assembly too.

The collective knowledge of the group is amazing. I'm not smart enough to weigh in so I'm just going to buy a griddle.

I wish it were that simple. Unless you use the griddle over a campfire, you will encounter a regulator!

There could also be oil in the line to the stovetop blocking the flow.
