Preparing The Type II (Liquid Fuel) Heater For Operation
Flammable liquids are used in the operation of the heater. Death or
severe injury may result from explosion or fire if personnel fail to observe
the correct operating procedures for heater units.
If the heater has not been used before, you will have to completely
assemble the heater outside of the tent (to include the six-section stack
assembly and tie down), burn off the protective film as detailed
previously in this work package, allow the heater to cool, disassemble
the heater, and then move the heater inside the tent.
Make sure you allow enough air space between the tent walls and the
heater unit, at least 4 feet (1.22 m). While in operation, the heater
exterior will become very hot. Frequently check for heating of the tent
walls while the heater unit is in use. If the tent walls become too hot, the
heater needs to be shutdown, allowed to cool, and moved to a tent stack
shield opening location farther away from the tent walls, if available, or
the amount of solid fuel used in the heater needs to be decreased.
Failure to follow these procedures could result in the heater igniting the
For best operation, be sure that the heater is as level as possible.

burned off), place the heater on the ground under a tent stack shield opening. If used on top of a tent
floor, the heater must be set on a bed of sand or placed on three or four bricks. Level the base by
