The high capacity thermostat is located in the top coil header. This cart system has the 3HT High pressure model (pressures up to 1000 psi) All cart system already include the gas hose, gas pressure regulator, striker, and pressure regulator. The cold water inlet is also connected in the top header above the thermostat's temperature sensing probe. The heater's main burner ignites immediately when water is turned on at the wand. When the water is turned off at the wand the thermostat reacts quickly and turns off when the water reaches the temperature set on its dial. This prompt thermostat action prevents the buildup of very hot water in the wand hose. Tests in our laboratory show a maximum output hot water temperature of 200°F when the thermostat was set on 180°F; and a maximum of 180°F when the thermostat was set on 160°F. This close control of the maximum water temperature is very important.
Extreme water temperatures in the hose reduces its bursting pressure rating. Bursting of a hose by 250°F water at 450 PSI pressure is very dangerous. Extreme water temperature at high pressure will burst into live steam when released through the wand to atmospheric pressure. Live steam will not clean as well as hot water 180° - 200°F. The live steam is also capable of harming the carpet and backing. The top water inlet is 1/4" Mip. No pressure hose or 90 degree elbow is provided. If you need a pressure hose or brass fitting to hook up your heater, please let us know.
