SPACE HEATER ARCTIC (SHA)
LOCATION AND DESCRIPTION OF MAJOR COMPONENTS
valve (16). Fuel vaporizes due to combustion heat and fuel vapor is expelled from the up-tube (20), down
through the down tube and into the burner shell (18) where it ignites. The down-tube (9) and up-tube (20)
are cleaned with the reaming tool (21), which is kept inside the heater body during storage (15). The
reaming tool (21) should be stored in an accessible yet protected location when not in use.
Fuel flow control valve (16). Mounts to a T shaped bracket (22) and slides into postion on the right
side of the heater body (6). The valve (16) functions safely with the liquid fuels specified in this work
package. When set properly, internal orifices match the viscosities of the fuels being used to meter the
correct fuel flow to the burner. The cup/cable assembly (23) is attached to the bracket and is used for
measuring fuel to prime the heater in liquid fuel mode.
Fuel can stand, collapsible (24) (optional item). Allows the fuel can (25) to be mounted in an inverted
postion to permit gravity fuel feed to the fuel flow control valve (16). (Note: The Fuel Can Stand is
available as an Additional Authorized Item as detailed in WP 0045).
Gravity feed adaptor (26). Threads onto fuel can (25). Hose (27) allows fuel flow from the fuel can (25)
during operation. The automatic vent (28) permits air to vent into the can for proper fuel flow to the heater.
Fuel hoses (29)(30). Fuel supply hose (29) allows fuel flow from fuel can (25) through the gravity feed
adaptor (26) to the fuel flow control valve (16), through the hose to the burner up-tube (20). An overflow
hose (30) drains fuel outside the tent in the event of a malfunction of the Fuel Flow Control Valve (16).
Hoses, (29) and (30), connect with quick-disconnect couplings. The fuel control outflow hose (31) delivers
fuel from the control valve to the burner assembly. The fuel supply hose (29) and overflow hose (30) are
both stored in the upper portion of the heater body (15).
