USING AN EXTERNAL FUEL SUPPLY
Fire or Explosion
Do not attempt to fuel a hot space heater. Shut-down the heater and allow the SHS to
cool completely before handling or fueling from an external supply.
In addition to its internal fuel tank, the Space Heater Small is equipped to accept an external fuel supply
such as a standard five gallon fuel can. Using an external fuel supply will greatly extend the operating
time of the heater. External fuel supply usage is optional and no external fuel supply components are
included with the heater.
To use an external fuel supply, select and set up a fuel supply site at least seven feet from the shelter in
accordance with safety and environmental guidelines. Ensure that the priming valve on the fuel hose
is closed by tightening in the clockwise direction. Route the fuel supply hose from the inside of the
tent through the small opening on the side of the shelter that is also used for the overflow hose. Lay the
fuel hose out to the fuel supply site, making sure that the hose is not kinked in any way.
Ensure that the fuel shut-off valve (1) on the heater is in the OFF position as shown on the fuel shut-off
Pull back the outer collar (2) of the female portion (3) of the fuel quick disconnect located just above the
fuel shut-off valve (1) and separate the female portion (3) of the fuel quick disconnect from the male
portion (4) connected to the fuel shut-off valve (1).
Insert the female end (5) of the external fuel supply hose into the male portion (4) of the fuel quick
disconnect of the fuel shut-off valve and push together while pulling back on the outer collar. Push the two
connectors firmly together and release the outer connector. Tug on the two connectors to ensure that
they are securely engaged.
Outside the tent, connect the fuel hose to the gravity feed adapter and mount the fuel can in the fuel can
