I have a Fiesta Dynasty 450 propane gas BBQ that has decided all of a sudden to not work so well.
The problem is that the gas flow to the burner seems blocked. I installed a full 40lbs tank, turned the tank on, and one side of the burner will hiss a bit then fade out, and the other side doesn't hiss at all. Burner is still in good condition, and I cleaned all the holes to make sure they weren't blocked, but like I said, the problem seems to be that the gas isn't getting to the burner.
Ok, finally the question. Can the hose from the tank to the burner be replaced ? If so, when replacing the hose, do the valves under the gas flow knobs come with it ?
Right now the BBQ will ignite, but will only give a minimal heat due to the gas restriction.
Suggestions anyone? (other than buy a new bbq lol) ;)

Most problems like this are due to the connection of the hose at the tank. Seals some times fail to enage correctly and don't fully open the passage to the burn. Close the tank knob on top, unscrew the hose and then reinstall. Open the valve and try again. Interest to know that with the modern tank you do not actually have to close the knob on top of the tank when replacing the tank. Full, partial and empty tanks will not leak gas if disconnected from the hose while the knob is open.

You're right... turns out the hose and regulator were shot. Purchased a new one from Fiesta for $30.00 and now all is good. Thanks for your help.
