Hi Alex - I put a "Safety First" brand in my
Boler. It was about 50 dollars US. I wired it to the lines coming out of the converter so that it will operate on either land line or 12 volt. I located it just to the left of the potty door - remember -
propane is heavier than air, so you want it down low. A good idea to put one in - isn't your life worth 50 dollars? Here's a pic - all the best - Alec
