~Travers, P(amela) L(yndon) Mr. Wigg, Mary Poppins's uncle. The 'particular day' is when his birthday falls on a Friday. Mary Poppins, chapter3. There were two hot air balloons that were tethered and attached to two pick up trucks so they only went a hundred feet or so up, for people who wanted to pay $25.00 for a few minutes. The waiting lines were steady at the Balloon Fest in New Smyrna Beach ~ Hot Air Balloons Wekipedia~ The burner on a Hot air balloon unit gasifies liquid propane, mixes it with air, ignites the mixture, and directs the flame and exhaust into the mouth of the envelope. Burners vary in power output; each will generally produce 2 to 3 MW of heat (7 to 10 million BTUs per hour), with double, triple, or quadruple burner configurations installed where more power is needed. The pilot actuates a burner by opening a propane valve, called a blast valve. The valve may be spring loaded so that it closes automatically, or it may stay open until closed by the pilot. The burner has a pilot light to ignite the propane and air mixture. The pilot light may be lit by the pilot with an external device, such as a flint striker or a lighter, or with a built-in piezo electric spark. Where more than one burner is present, the pilot can use one or more at a time depending on the desired heat output. Each burner is characterized by a metal coil of propane tubing the flame shoots through to preheat the incoming liquid propane. The burner unit may be suspended from the mouth of the envelope, or rigidly supported over the basket. The burner unit may be mounted on a gimbal to enable the pilot to aim the flame and avoid overheating the envelope fabric. A burner may have a secondary propane valve that releases propane more slowly and thereby generates a different sound. This is called a whisper burner and is used for flight over livestock to lessen the chance of spooking them. It also generates a more yellow flame and is used for night glows because it lights up the inside of the envelope better than the primary valve. Propane fuel tanks are usually cylindrical pressure vessels made from aluminium, stainless steel, or titanium with a valve at one end to feed the burner and to refuel. They may have a fuel gauge and a pressure gauge. Common tank sizes are 10 (38), 15 (57), and 20 (76) US gallons (liters). They may be intended for upright or horizontal use, and may be mounted inside or outside the basket. Stainless steel fuel tanks, wrapped in red insulating covers, mounted vertically, and with fuel gauges, during refuelingThe pressure necessary to force the fuel through the line to the burner may be supplied by the vapor pressure of the propane itself, if warm enough, or by the introduction of an inert gas such as nitrogen. Tanks may be preheated with electrical heat tapes to produce sufficient vapor pressure for cold weather flying. Warmed tanks will usually also be wrapped in an insulating blanket to preserve heat during the setup and flight. A balloon may be outfitted with a variety of instruments to aid the pilot. These commonly include an altimeter, a rate of climb (vertical speed) indicator, envelope (air) temperature, and ambient (air) temperature. A GPS receiver can be useful to indicate ground speed (traditional aircraft air speed indicators would be useless) and direction.

This is my bulk head connection and custom hard lines viewed from inside the cab under the dash. Hot Rod Air set-up. The cable actuates the heater valve which I mounted inside of the cab. Despite the possibility of leak occuring inside the cab, I chose this location over mounting that ugly piece of hardware in my engine compartment. The other alternative was to go with the servo type valve but they are not half as durable as the manual-cable type.
