If you have some methol hydrate or gas line antifreeze pour it into regulator while you have it off like moyerboy told you and flush it out, pour it in the vents on reg too then dump it out, when reconnecting to the tank hook up to tank and leave other oen open and turn tank on! keep reg facing away from you and protect eyes from anything that may come from reg. you should see rest hydrate shoot out and have a decent gas pressure.

Turn the tanks off outside and take the regulator off the tanks and the main line and bring it inside and thaw it out the regulator is frozen and won't open. Thaw it out and put it back on and it should work if not you may need a new regulator.

Have a 1985 Apenlite. Having an issue with the propane system. Tanks are full and opened. However there is no propane getting to the water heater or stove. Any suggestions?

Check the regulator to make sure it is delivering gas. The other thing is it won't deliver unless you are level.

How to turn on water heater

This might not be much help, without more details, but there should be a valve inside the water heater panel (outside) you can open. Open the valve at the main propane tank also.

Make sure the water tank is FULL before you fire it up. There should be a switch inside the coach somewhere to turn it on.

If it doesn't ignite immediately, you probably have air in the lines. Light the stove and let it burn for a minute, then try the hot water tank again. Might take a few tries to get it fired up.

Truma water heater water wont come out of the taps when on gas, 12 volt or mains 240 volt

Bleed your propane system by running the stove for a sec. if that doesn't work go out to the heater and listen for the ignitor clicks see if it's trying to lite. My fifth wheel does this first time every season.

When the new furnace is on, the stove flame is very minimal. Before we replaced the furnace, we could run the dryer, stove, furnace,and water heater at the same time. We have also changed propane dealers....

The "Service man" is correct! I'm totally shocked that it has worked for 36 years with a 3/8" line.

Frankly, whoever installed the line didn't know what they were doing. A 3/8" line will produce a substantial amount of gas pressure. But, it's not large enough to provide the volume of gas to carry all those appliances at the same time. On checking my REGO sizing manual, the minimum that you should have is a 1/2" line, for a run no longer than 40 feet. If it's over that, it should be a 3/4" line.

If you're running a high pressure 2lb system, you ca get away with a 1/2" line. However, every gas appliance will have to have it's own properly sized regulator to maintain the proper pressure when more than one appliance is running at the same time.

I have a 1993 fleetwood bounder i have had it for two months. i just got around to the propane appliances but there is no propane flowing to the stove or the furnace. the tank is turned all the way on but...

Ok, Lets start at the beginning. First make sure there is propane in the tanks! Gas can leak rom these tanks sometimes at a very small rate and over time they can go empty if there is a loose fitting somewhere. When you turn on the stove is there any air or hissing sounds coming from the burners? Air can get in the lines and when you turn the gas on, you get nothing but air for several seconds till the air bleeds out then you get the gas. Hold a lit match next to the burner and watch to see if there is any movement to the flame on the match, movement would let you know if there is any air coming from the burner, hold it there for a few seconds and see if any gas comes thru and this will then lite the burner. I always have to turn my stove on for a while to get gas thru the lines so the appliances work after the tanks have been filled or after it sits for a while. Once you get gas thru to the stove you can try your heater, this may also take sewveral tries till all the air is purged from the lines so don't get frustrated, sometimes this can take a while! Then the next thing is the water heater, the gas valve on these has a selection for pilot lite, turn the red knob so thet the cut out in the knob lines up with the gas valve and you have to push and hold this down for a minut or longer to get gas to the burner. Once the burner lights hold the pilot knob down for another minute to make sure all the air is out of the system. Once these are done you should be good to go till next time your tank runs dry and has to be filled. If you determine there is gas in the tank but it is not flowing to the appliances, double check all the shut off valves. The tank should have a diagram on the valve to let you know which way it turns for on and off. Do you have a built in tank on this model? If you have the two removable tank set up, make sure the auto switching valve is set correctly and you have it on to the tank that is full. If you still aren't getting gas, try calling an RV dealer and ask them if there is another valve somewhere that might need to be turned on. There migt be a shut off in the line somewhere, but this is not common.

Propane tank was almost empty and when the heater/stove came on, it sounded like air coming in. It made a lot of noise, hissing like. Tank full now and occassionally when the heater lights, there's a big...

First of all you need to give more details with your questions.... is this an atmospheric burner, a ventless, a direct vent or a high efficiency. Since you haven't put this down, I will guess that it is an atmospheric (those who know little about propane always go with the cheapest option) As for your problems....The two are totally unrelated. Check your air gas mixture. it sounds like you need to adjust your burner venturi sleeve.

Propane gas burner now has red flame instead of blue

Hi, If you have the same problem with your stove , furnace and water heater, Then you look for things in common that would cause the problem. Any change in the flames is an indication of a change in the fuel/air mix. The item that would be common to all would be the pressure diaphragm. This is not something a customer should work on without a through knowledge of how they work. I think you would be well advised to have a service call. Good Luck!

Are you any issues with any other appliances? (i.e. Water heater, range, oven , furnace) If you are having issues with your regulator(on the propane tank), then other items would be affected also.
If your ignitor is trying to ignite, then you are not getting gas to the burner.
  1. Replace the thermacouple.
  2. If this does not fix the problem, then you are looking at a bad gas valve.
