	The Air System: The motor turns the fan. The fan pushes air into and around
	the combustion chamber. This air is heated and provides a stream of clean, hot air.
	The Ignition System: The piezo ignitor lights the burner.
	The Automatic Control System: This system causes the heater to shut down
	if the flame goes out.	Fan

The amount of propane gas ready for use from propane tanks varies. Two factors decide this amount:

1.The amount of propane gas in tank(s)

2.The temperature of tank(s)

This heater is designed to operate with a minimum 20-pound propane tank. You may need two or more tanks or one larger tank in colder weather. Use a 100-pound tank for longer operation or in very cold weather. Less gas is vaporized at lower temperatures. Your local propane gas dealer will help you select the proper supply system. The minimum surrounding air temperature rating for each heater is -20°F (-29°C).
