Hunter has this to say about the H45,"The H45 space heater manufactured by Hunter for the U.S. military is a non-powered, freestanding, liquid multi-fuel space heater and is designed for heating the military's general purpose (GP) tents, small and large".

"This unit provides reliable heating using a fuel vaporizing technology that has been tested in the laboratory and in the field. The H45 heater has been in service for many years and thousands of units have been put to use. The exhaust stack (included) vents all exhaust products outside. " "The H45 space heater is a 45,000 BTU heater that is designed to provide heat for the GP and TEMPER tents. The H45 operates without the use of electrical power and can burn wood, coal, DF2, DF1, DFA, JP5 and JP8. The H45 utilizes vaporizing R-tube burner technology."

WARNINGS-The metal surfaces of the H-45 heater body are protected with a preservative film when shipped from the manufacturer that must be burned off prior to first time use of the heater in an enclosed area. To burn off the protective film, set up the H-45 in an open outside area and light in accordance with WP0005. Once the heater is hot, smoke will be seen coming off the metal surfaces as the preservative burns off. Allow the heater to burn until no more smoke is observed. Shut the heater down, allow it to cool.

Do not attempt to handle or perform services on an H-45 that has recently been in operation. Let the space heater cool down before performing these procedures. Failure to do so could result in serious burns. WARNING The H-45 weighs approximately 72 pounds (32.66 kg) for the Type I (Solid Fuel) and approximately 75 pounds (34.02 kg) for the Type II (Liquid Fuel). Two persons must carry the H-45, lifting with legs, not back, to prevent injury. WARNING Some metal components of H-45 may have sharp edges. Wear protective gloves and be careful when handling and assembling the H-45 stack pipe. Failure to do so could result in serious cuts. WARNING Protective gloves should be worn when handling metal parts in below freezing temperatures. Failure to wear gloves may result in skin freezing to the metal upon contact and cause tearing of the flesh when attempting to pull away from the metal. Do not allow liquid fuel to come in contact with bare skin. Wear protective gloves whenever handling or working with liquid fuel. Even though fuel does not freeze, it is extremely cold and will burn exposed skin on contact.
