Atwood water heater not igniting

[nomad297]

Have you turned your propane off and back on recently? Have you tried firing your furnace up yet? If not, you might want to see if it is working properly and producing heat. If it isn’t firing the burner and producing heat, you may have a restriction or a bad regulator at your tank/s. You can get enough propane to make a flame at your stove, and you can get enough propane to be able to smell it at your water heater exhaust and at your furnace exhaust, but there won’t be enough flow to allow either of these high-consumption appliances to light. If your furnace won’t fire, try disconnecting the propane from the tank/s. Wait a few seconds, then reconnect and turn the propane back on very slowly, then see if things work. There are several other things that could be wrong, but this is the easiest one to check and eliminate.

You can test for a bad regulator with a manometer. You need to know what your system’s water column should be working at while static, and you need to know what the acceptable water column drop is for the system when all appliances are using gas. This is just the basics of testing a regulator. You can find the details on YouTube and other websites.
