I have an endless summer 92000 table top propane heater. Lights fine, but the flame does not burn at the edge of the burner. Instead, it only burns in the very center of the burner... much like a Bunsen burner... making a loud hissing sounds as it burns. All parts are 100% free of obstructions. Is this a regulator issue of a control valve issue, or a burner design issue. My other patio heater is the same model and has been working flawlessly

Actually, it's a gas pressure issue. But, it's fairly easy to solve. First, you need to be sure that your LP Tank has a sufficient amount of gas. If it does, turn the propane tank valve OFF. Disconnect the hose from the tank and wait 5 minutes. Then reconnect the hose to the tank and turn the valve ON VERY, VERY SLOWLY (Slow motion, slow). Once the valve is fully open, light the burner as you normally do and turn the burner flames to HIGH. Has the burner flame returned to normal? If so, you solved the problem. Just remember to always turn the tank valve ON very, very slowly.
If it didn't solve the problem, you will need to replace the heater's hose/regulator assembly. Generally, i's the same type that a gas grill uses. So, it won't be hard to find one.
Hope this helped to troubleshoot and solve your problem. Please let me know.
