Hi, have a new 3761FL, should I have both propane tanks open or just one.
The tank has a green G on it, how do I know when to fill tanks

I use one at a time when one runs out I just move the full one to the empty side and fill the empty.

When the stove will not light you are out of propane.or at least that is how I do it.

Your regulator that has the red and green indicator on it will tell you which tank is empty. With both tank valves open and the handle of the regulator pointed in one direction or the other, and both tanks with gas in them, flipping the handle will show green on both tanks. With both tanks open, when one tank goes empty, the regulator will internally switch to the full tank but the indicator, still pointing at the empty tank will now show red, telling you it's empty. You flip the handle to the other tank and the indicator will change to green. You then close the valve on the empty tank and you can disconnect the tank to take it to be filled. Once filled, you reinstall the tank, SLOWLY open the valve, and you are ready to go. Once the other tank becomes empty, you do the same routine with that tank, and back and forth from one tank to the other. Depending on the season, I check the indicator every couple of days or in warm weather I will go longer. Never have to get up at 3:00 in the morning to have to go out to manually switch tanks because the furnace stopped working.

Bob has all your answers, but just to add one to the mix I leave them both open all the time and change the one that goes red. Others must have different experiences but if I only opened one at a time the gas would run out in the middle of a cold winter night.

Bob and Dick do it exactly as I do. The regulator has an automatic switch over so why not take advantage of it? Changing tanks at 3:00 AM is crazy. Yes you have to check for a red flag periodically. Just like you check the fuel, oil, DEF level in your truck. You will learn how long a tank lasts, in different conditions, as you get more experience.

What DQDick said.

I have 2 tanks with a selector to choose which tank to use. I use one tank until it's empty then switch the selector to the other tank and refill the empty tank.

I only have one open. That way, I never run out of gas. Now for using the propane in the middle of the night, I try my best to keep the RV warm by using the fireplace, and a small space heater, so I am using the parks electricity, rather than using my propane to run the furnace. I use the furnace only to quickly heat up the RV, if I have been out, and it is a cold winter day, so it helps the other two methods have a chance at keeping it warm. So when one tank runs out, I go open the other tank, and then fill the one that went empty the first chance I get.

I don't mind the minor inconvenience of having to switch the regulator from one tank to the other when the first one runs out. We don't run our furnace at night because the blower is too loud. An electric blanket and the fireplace work well for temps down to freezing. If the furnace stops or the gas stove won't light, I can switch to the other tank and get the first one refilled. That way I don't have to look at the regulator every few days and I'll never run out of propane if I get the empty tank refilled promptly.

I put these on my tanks. I was in a cold weather area for a couple of years and kept 3 extra tanks handy. If I saw one was low, I’d switch it out before nightfall.
