1.
LOW FLAME |
 |
|
| CAUSES: |
A.
Carbon deposits on wick - indicate use of low quality
fuel - flush and
fill tank with good fuel - burn dry - re-fill with
good fuel, carefully clean
wick adjuster and primary air tube, and check flame
height. If flame is high enough, operate
as is. If flame is still too low and
heater has wick life
extender, raise to next higher step. If
there is no wick life extender, replace wick and
check wick height.
B. Water in fuel tank and in wick - will not be
removed by burning dry.
Water will retard fuel flow even in wicks clean
and free of carbon deposits.
When water is suspected, empty and dry the tank,
flush and fill with fresh,
uncontaminated fuel, change wick and then observe
flame.
C. Fuel too heavy and/or too cold - an exceptionally
heavy or oily
kerosene will travel through the wick and evaporate
more slowly than a lighter one. Kerosene
at low temperature (for example -18°C to -1°C,
0°F to 30°F) will move and evaporate much
more slowly than same fuel at 16°C - 27°C
(60-80°F). Be sure you take this
into account when you face a "low-flame"problem.
Allow the unit plenty of time to warm up. Also,
cold fuel will take longer to completely soak the
wick.
D. Wick height too low - If wick is too low any
of the three problems above will be more severe.
Measure wick height and compare to requirement statedin
owners manual. Always operate the unit
at the flame height designated in the manual. DO
NOT "turn down" the wick if the room gets
too warm. Turn the heater off or increase
ventilation. |

2.
ODOR DURING START-UP AND SHUT-DOWN |
| |
|
| |
Increasingly
strong odor usually goes along with increasing deposits
on the
wick - clean the wick as instructed, refill tank
with good quality kerosene.
Be sure to clean the wick adjuster and primary air
tube thoroughly.
Also check to see that wick height is sufficient. |

3.
ODOR DURING OPERATION |
| |
|
| |
Odor
during operation may be caused by impurities in
the kerosene,
an exceptionally dirty wick, or kerosene spilled
on the wick adjuster, fuel sub tank, drip tray,
etc. Clean the heater thoroughly, burn it dry to
clean the wick. If odor persists, change to better
quality fuel. If a burning sensation is observed
in throat, nose or eyes, it is imperative to switch
to good quality kerosene as soon as possible. |

4.
SLOW START-UP |
| |
|
| |
Slow
start-up can be caused by dirty wick, cold or very
heavy fuel and/or low wick setting. If wick is dirty,
burn it dry, clean wick adjuster and primary air
tube, refill tank with good quality kerosene, check
wick height.
If fuel is cold, allow extra time for start-up. |

5.
FLAME TOO HIGH BUT STEADY |
| |
|
| |
Flame
too high but steady indicates the wick is set too
high, room temperature is too high, or fuel that
is more volatile than regular kerosene. Turn
wick down to adjust flame to proper level. If
flame stays at proper level, then wick height is
the problem. If room temperature is above
27°C (80°F), extinguish the heater. If
flame continues to increase even after it is adjusted
downward, it indicates that the fuel is too volatile. Using
the wick adjuster knob, carefully turn heater off. Allow
it to cool, empty the tank and refill with uncontaminated
good quality kerosene. |

6.
FLAME HIGH AND UNSTABLE/SOOTING |
| |
|
| |
High,
unstable flame and sooting can be caused by the
heat chamber being improperly seated, the wick adjuster
not properly seated and sealed into tank, or by
operating heater in strong air drafts. Check to
see that heat chamber is seated properly. Then examine
seating of wick adjuster into tank, tighten using
screws if possible; move heater to area free of
wind drafts. |
| |
|
| NOTE: |
In
some cases, a high, unsteady (sometimes it appears
to pulse) flame occurs after an hour or two of operation
if the fuel is too volatile. If such behavior is
observed, turn the heater off carefully and allow
to cool. Remove the fuel from the tank. Flush tank
and refill with uncontaminated good quality kerosene. |

7.
WICK HARD TO RAISE OR LOWER/EXTINGUISHER SLUGGISH
OR
FAILS TO DROP (WICK DROP TYPE EXTINGUISHER) |
| |
|
| |
Usually
indicates that wick is encrusted from use of poor
quality fuel, or may be swollen by absorption of
water. If heavy encrustation is seen on wick clean
it be burning dry. Then clean wick adjuster and
primary air tube thoroughly, refill tank with good
quality kerosene. If wick appears clean but is hard
to raise or lower, water in the tank and wick is
indicated. Empty tank, flush, dry with paper towels
and fill with fresh good quality kerosene. Change
the wick and reassemble heater. If heater has wick
sleeve, check the shape of it. If wick sleeve has
any deformation, replace it. |

8.
EXTINGUISHER SLUGGISH OR FAILS TO CLOSE
(IRIS TYPE EXTINGUISHER) |
| |
|
| |
Slow
closing of the extinguisher mechanism usually indicates
dust accumulated on the blades of the iris. Wipe
the blades thoroughly with a dry cloth, then with
small amount of kerosene on a soft clean cloth.
Cleaning and lightly lubricating the blades with
powdered graphite will restore them to proper performance. |

9.
IGNITER COIL GLOWS BUT DOES NOT IGNITE WICK |
| |
|
| |
Indicates
that the igniter batteries are too weak, or the
igniter is not positioned properly relative to the
wick. If igniter coil is too far from
wick, adjust igniter arm so that the igniter coil
will be less than 1 mm from the wick. If igniter
coil is touching wick surface, this is too close. Adjust igniter arm to move coil just slightly away
from surface of wick. If wick is set too high, turn
it down in small steps while trying to ignite itbetween
each step. |
| |
|
| NOTE: |
f
igniter coil seems to be positioned properly relative
to the wick,
but will not ignite the wick, install new batteries. |
