Propane is corrosive to some materials. Especially some types of rubber which, in the case of an improperly used hose, deteriorate undetected from the inside out. Pressures can become excessive, fire will burn you, things can blow up. This is dangerous, you are responsible for your own safety, do not blame me.

Here are a few resources to begin researching. Understand completely what is required and why:

  Assembly Diagram
    This is a later design than shown in the images on this page. Problems developed by
    attaching the barrel directly to the top of the accumulator. Vibration stress caused the
    barrel to crack at the threads. This diagram shows a 1/2" propane rated hose connecting
    the effect valve to the barrel to eliminate vibration stress at the barrel's threads.

As the surface of the supply tank cools vapor pressure drops. By adding a second supply tank, and more surface area, vapor pressures can be maintained for a longer period of time.
