EXTINGUISHING THE HEATER
To extinguish the heater, push down on the manual shut-off knob(Fig. 18) with one
hand while holding the wick adjuster knob in the other hand. You will feel the
pressure of spring action attempting to turn the wick adjuster knob in a counter-
clockwise direction in your hand. By slowly relaxing your grip on the wick adjuster
knob, you will allow the spring to gradually lower the wick and extinguish the flame.
When there is no further pressure from the spring action, confirm that the wick has
been fully lowered by turning the wick adjuster knob in a counter-clockwise direction
as far as it will go.
After 10-15 seconds, open the door on the body of the heater, lift the burner using
the burner knob, and visually confirm that there are no flames present. This will
confirm that the heater is completely extinguished.
CAUTION : After extinguishing the heater, allow at least 10 minutes before reigniting the heater. This allows the
heater time to cool off and return to a normal temperature. Failure to allow the 10 minute cooling off
period before reigniting the heater will result in the creation of a strong odor and possible flare-up.
WARNING : Carbon and tar can build up on the wick after the heater has been in use for a while. This can interfere
with the ability of the wick to be lowered into the body of heater, and can result in the flame not
extinguishing completely. It is the responsibility of the owner to inspect the wick, to maintain proper
maintenance of the wick, and to replace the wick when necessary in order to prevent the build up of
carbon and tar from creating a dangerous situation where the heater does not fully extinguish.

AUTOMATIC SAFETY SHUT-OFF DEVICE
This heater is equipped with an automatic safety shut-off device. The purpose of this device is to quickly and
efficiently shut-off the heater should the heater be jarred or tipped over while in operation. This is the main safety
system that is built into the heater, and it functions to prevent the flame from spreading if the heater is knocked
over.
The automatic safety shut-off device is built into the mechanism that raises and lowers the wick. It has been
designed so that if the pendulum is jarred by a shock of some sort, it retracts a latch from the wick control shaft
ratchet, and a torsion spring reacts to drop the wick to its fully lowered position. This rapid lowering of the wick
extinguishes the flame.
If you find that the wick will not raise, push the safety reset lever (see diagram on P.2) to engage the automatic
safety shut-off device. Then dial the wick up via the wick adjuster knob.
IMPORTANT NOTICE : For the safety shut- off device to function properly, the wick must be free of carbon and tar
deposits. Regularly performing the "Carbon Removal / Dry burning" procedure described
in the "Wick Maintenance" and "Carbon Removal / Dry Burning" sections on page 10 is
very important to the proper functioning of this important safety device.
IMPORTANT NOTICE : PLEASE CHECK THE SAFETY SHUT-OFF DEVICE ONCE A WEEK DURING THE
HEATING SEASON TO INSURE THAT IT IS FUNCTIONING PROPERLY.
IMPORTANT NOTICE : EVERY TIME THE WICK IS REMOVED OR REPLACED, THE SAFETY SHUT-OFF
DEVICE MUST BE TESTED TO INSURE THAT IT IS FUNCTIONING PROPERLY.
