Troubleshooting Issues Filling A Flame King Horizontal Propane Cylinder Tank

Although the Flame King 20lb Horizontal Propane Cylinder Tank With Valve and Gauge Rv Trailer can be used in the horizontal position it still needs to be refilled vertically.

The Overflow Protection Device (OPD) is very sensitive and sometimes it can get stuck while in transit.

If you’re having difficulty filling the propane tanks on a TrailManor, please try the following tips from the tank manufacturer:

We recommend gently putting the tank on its side on a soft area such as a carpet or grass, etc. and roll it around for a minute or two. Also hold the tank right side up, invert it, right side up, invert it etc. do that a few times a bit vigorously.

Also, in general when filling for the first time, this procedure should be followed — pump turned on when the valve is still closed, then open the bleeder screw and slowly open the valve handle. If that doesn’t work you may want to view the video below to see the process in full. A very common issue occurs when a filler may pump the gas in too quickly, which would lock the OPD. The screwdriver method can unlock it. Try the part mentioned in the video regarding releasing the pressure from the tank via the screwdriver method. That is demonstrated at the 1:35 mark of the video.
