ASPHYXIATION AND CARBON MONOXIDE POISONING
WARNING. Unvented heaters consume oxygen and produce carbon monoxide.
Asphyxiation may result from breathing high levels of carbon monoxide. Use only in well-
ventilated areas, and adjust wick in accordance with instructions in the Owner's Manual.
Never operate heater at a wick-setting lower than the minimum wick-stop setting.
1. People with respiratory or circulatory problems should consult a physician before using
the heater.
2. Houses with unusually tight construction due to heavy insulation and tight seals may
have low levels of fresh air infiltration; therefore, provide an adequate supply of fresh air
for combustion and ventilation by keeping the door(s) to adjacent room(s) open or a window to the outside open at
least one inch, to guard against the potential build-up of carbon monoxide. (Fig.M)
3. ALWAYS make room temperature adjustments by extinguishing the heater or by opening windows, rather than by
adjusting the wick.
4. NEVER adjust room temperature by means of the wick adjuster knob. This should only be used to maintain the
proper flame (See 7 below). If heat is reduced excessively by means of the wick adjuster knob, it will cause
imperfect combustion, which may result in the accumulation of carbon on the wick, unpleasant odors, and/or the
generation of carbon monoxide.
5. DANGER. NEVER operate heater at a wick-setting lower than the minimum wick-setting.
6. NEVER operate the heater with the wick improperly adjusted. A low wick setting may produce carbon monoxide,
which can cause dizziness, nausea, headaches or even death, in extreme cases.
SOOT AND SMOKE
CAUTION. Soot and smoke emissions will result if contaminated kerosene (Never use
kerosene that is even slightly colored or cloudy), if carbon deposits accumulate on wick, if
wick is not adjusted properly, or it burner unit is not seated properly. Soot and smoke
emissions can cause respiratory tract irritation and can damage property. Use only pure
1-K kerosene; remove carbon deposits on the wick periodically, in accordance with the
operating instructions in the Owner's Manual; and adjust wick- setting periodically, in
accordance with the operating instructions in the Owner's Manual. (Fig.N)
1. NEVER operate the heater while it is unattended.
2. NEVER operate the heater without a working smoke detector and fire extinguisher nearby.
3. NEVER use poor quality kerosene (i.e., kerosene that is aged, discolored, contaminated or that was obtained from
an unknown source), which may cause excessive carbon build-up on the wick. Excessive carbon build-up may
prevent proper wick retraction and heater extinguishment, resulting in the generation of strong odors and soot or
smoke. (For details, see section entitled "Extinguishing The Heater" in the Owner's Manual.)
4. ALWAYS check kerosene to be sure it is colorless. ALWAYS check kerosene(colorless) for clarity at the point of
purchase.
5. ALWAYS confirm extinguishment of the flame by lifting the burner knob and checking visually, prior to leaving the
room for any period of time and before retiring to bed. (For details, see section entitled "Extinguishing The Heater"
in the Owner's Manual.)
6. ALWAYS remove carbon build-up from the wick within 5 to 7 days of the first use, and after burning 5 or 6 tankfuls,
during periods of regular usage. Carbon build-up on the wick can cause the production of soot and smoke.
(For details see section entitled "Carbon Removal Dry Burning" in the Owner's Manual.)
7. ALWAYS make periodic adjustments of the wick during heater operation. Use the wick-adjuster knob to make
basic adjustments within 5 to 7 minutes after ignition, and again after 30 minutes, if necessary. Because of changes
in heater temperature and room temperature, flame height inspections and adjustments must be made periodically,
thereafter. (For details, see section entitled "Adjusting the wick" in the Owner's Manual.)
8. ALWAYS remove and properly dispose of unused kerosene when storing your heater to avoid using the
deteriorated kerosene after long-time storage, resulting in imperfect combustion. Kerosene held over can absorb
water that may adversely affect system performance.
9. NEVER use an unauthorized replacement wick in this heater.
