Kenmore Range Propane Conversion - Propane Smell from Conversion Plug

I recently converted a new Kenmore range (Model #790.70402012) from natural gas to propane. My conversion plug in the regulator did not look like the one in the conversion instruction drawings (Figure 1, attached), but I followed the instructions to remove it and turn it around. The solid end now faces into the regulator, and a small inscription on the hex nut reads "LP" and has arrows pointing in towards the regulator. I re-installed it, tightened it, and replaced the plastic cap (Figure 2, plastic cap removed to show orientation). When I turn gas on to the range and try to ignite the burners, everything works correctly, except there is a gas smell. It seems to be coming from the conversion cap (through the small pin hole in the end that now faces the regulator (visible in Figure 3)). There is a hissing sound and a gas smell coming from the area, and when I remove the plastic cap (keeping the metal conversion plug in place) I can feel gas coming out and the smell gets more intense. What can I do to stop this leak? Thank you.

The instructions for the type of regulator cap that you have is shown in the image below. A qualified installer should complete that LP conversion.

That hole in the cap of the regulator is a vent and there are situations where you may get a whiff of gas out of that cap but if you are detecting a steady flow of gas out of the vent hole in that regulator then you may have a bad regulator. The diaphragm of that regulator may be leaking. In that situation, I recommend that you have a service technician examine the range. If the conversion was completed properly by a qualified installer and the regulator is defective, then you should not be charged for that service if the range is less than a year old. The warranty information is in the owner's manual for your range. Here is a link for that manual in case you need it:

. You can call Sears at 1-800-469-4663 (1-800-4MY-HOME) for service.

I hope that this information helps. If you need more assistance, reply with additional details.
