NEVER LEAVE THE HEATER

UNATTENDED WHILE BURNING!

8

NOTE : During start-up, small adjustments to the flame can be performed by using
the burner knob on the front of the burner and MOVING THE BURNER FROM
SIDE TO SIDE 
until the flame at the top of burner is as even as possible. 
DO NOT TOUCH THE BURNER KNOB ONCE THE HEATER HAS REACHED
NORMAL OPERATING TEMPERATURE AND THE FLAME HAS STABILIZED.
THE BURNER KNOB IS VERY HOT DURING OPERATION.

IMPORTANT NOTE : This heater is designed to operate with a flame
height of no more than 1/2" at the top of the burner. For proper
combustion to occur, it is very important that the flame height be
adjusted so that it is neither too high, nor too low.  Operating the heater at a wick setting below the minimum
recommended setting (the wick-stop setting) could result in the risk of fire and / or carbon monoxide poisoning.

NOTE : If you find that the wick will not raise, push the safety reset lever (see diagram on P.2) to engage the

safety shut-off device. Then dial the wick up via the wick adjuster knob.

WARNING : RISK OF INDOOR AIR POLLUTION AND FIRE, DO NOT OPERATE HEATER AT WICK

SETTING LOWER THAN MINIMUM WICK-STOP SETTING.

WICK MAINTENANCE / HOW TO CHECK THE CONDITION OF YOUR WICK

Failure to clean your heater’s wick may result in low heat output, cause your heater to burn with an annoying odor and could
damage or destroy the wick adjusting assembly. It can also make it very difficult to light the wick. 
Carbon and tar will accumulate on top of the wick as the kerosene burns and must be removed. How often you need to "Dry Burn

"

depends on your use of the heater and the quality of fuel available. The best way to know is to check the wick often.

Check Your Wick Often!

If the wick is hard to light using the heater’s ignition system...
If the wick is hard to raise or difficult to adjust by turning the knob...
If the wick fails to drop completely when you push the shut-off knob...
If the top of the wick is stiff & hard like a bristle brush...
It is time to DRY BURN your heater. A wick that is in good condition will feel soft to the touch, light easily

and extinguish quickly.

Note: Poor fuel or fuel contaminated with water will also turn the wick hard.

"DRY BURNING" YOUR HEATER / REMOVING CARBON FROM YOUR WICK

"Dry burning" your heater will cause a strong odor. For this reason it is best to 

"

dry burn

your heater outdoors on a day that is

completely calm and windless. If it s too windy outside you can consider a porch, breezeway or other room with all of the windows
open to disperse the strong odor.

Step 1

With your fuel tank nearly empty, burn your heater (without refueling) until the flames starts to burn out,then raise the
wick to it s highest possible setting and leave it there until it burns out completely. Wait 60 minutes, then re-light the
wick (with a match if necessary) and allow it to burn out again. Once the heater is cool to the touch, remove the cabinet
and brush the top of the wick with and old tooth brush,or other stiff bristle brush,to remove any remaining ash. A
canister type vacuum cleaner may be a useful tool in removing this ash.

Step 2

The first step should remove most carbon and your wick should feel softer to the touch. If any part still feels  hard, you
can use small pliers to pinch these hard spots and break up the carbon into pieces. After doing this, replace the
cabinet, add a small amount of fuel, wait at least one hour and then repeat Step 1.

Carry out Carbon Removal/Dry Burning within 5-7 dasy after your first use of your new heater to reduce carbon build-up on the
wick’ s burning surface. Afterwards, Dry burn your heater anytime the wick appears to be hard. CHECK YOUR WICK OFTEN!
Dry burn your heater and remove all fuel from your heater at the end of the heating season.

Note: Burn your heater Dry, as noted above, weekly during the heating season. Check your 
wick often to see if CARBON REMOVAL/DRY BURNING is necessary. Carbon removal will NOT
be effective if your fuel has been contaminated by water or any other liquid. In this case you               
must clean the fuel tank, replace the wick and soak it for 60 minutes in Fresh, 1-K Kerosene.
