Choosing a lamp to burn
A used lamp often is dirty, may contain old kerosene,
be damaged and be missing parts or have parts from multiple
different lamps installed. At first glance it may
not look like much. But with a little cleaning, some new parts
that lamp can often be made to work like new again.
The very first thing you need to do is determine what you have
and what condition it is in. A lamp meant for display just
needs to look pretty and appear to be complete from the outside. A
lamp meant to be burned needs to have a full compliment of compatible
parts and all those parts need to be in good functional condition.
Also there were burner versions that really should not be burned
on a regular basis such as the Brazilian model C. And some burners
have
hit of miss quality issues such as the early Hong Kong model 23
burners.
If you are looking to purchase a used lamp for the purpose of
burning it, an evaluation of it's condition should be made before
purchase.
- Burner: The burner is a precision device designed
not only to raise and lower the wick but to direct and meter
the air
flow to the wick and mantle. The first thing you should
do is see if the wick adjuster arm wobbles from side to side. When
a wick is installed there should be no wobble. When
a wick holder is not installed, the arm should wobble very
little if at all. Wobble happens when someone tries to
force a stuck wick. Forcing the gearing can bend
and loosen parts. Avoid burners that have wobble in the
wick adjuster knob. Some
wick adjuster problems can be repaired but repairs
often require expertise at fixing them.
Also look for cracks in the burner and any damage. In
general avoid a damaged burner and wick adjuster knobs
that wobble.
- Inner and Outer Wick Tubes: The wick
is held in place between two concentric brass tubes. One or more
of these
tubes is often cut off if the lamp has been electrified. A
lamp will not burn with one or more either missing or
damaged. For the wick to adjust easily, the inner and outer tubes
need to be concentric
and present a smooth surface to the wick.
Deep scratches with ridges, dents in the tubing or inner and outer
tubes offset
to one side will all keep the wick from adjusting easily
and will make the lamp difficult to burn.
The draft tubes of models 1 through 6 are also the inner
wick tubes. Remove the burner and carefully examine
the tube for ridges, dents or cracks. The outer wick
tube is part of the burner base. You need to remove
the wick to examine the outer wick tube.
Model 7 and newer burners have both the inner and outer
wick tubes in the burner base and requires removing the
wick to inspect either.
- Gallery: The gallery must be compatible with the burner (see
chart below) and in good condition. Inspect the condition
of the chimney and mantle mounting surfaces for damage.
- Generator/ Flame Spreader: The generator must
be compatible with the burner (see chart below),
in good clean condition and properly seated. The generator meters
the amount of air
being fed to the inside of the wick and mantle. It also
creates an even flow of air directed by the placement of the
holes. During prolonged
use, the metal between adjacent holes may burn out creating
a larger uneven opening. Do not use a damaged flame spreader. I
suggest that rare generators not be used for burning lamps when
common
easily
replaceable
compatible versions can be used instead.
All of these items should be carefully inspected on a lamp intended
to be burned and any component not in very good condition should
be replaced. Remember, Aladdin burners are precision air
metering devices.
Burners by model:
Models 1 & 2: These use a cap mantle
which has been unavailable for about 75 years. Unless you
are an expert at burning Aladdin lamps I suggest just displaying
them. Late model 2 lamps came with a model 3 gallery and
use a Kone Kap mantle. It could well be possible to reliably
burn a model 2 lamp using model 3-6 galleries and 3-6 generators. I
have not tried this, nor is this mentioned in any of the Aladdin
documents I have found. But if you want to burn a #2 lamp,
it is worth a try. You would need to rework a wick
to fit the #1-2 wick holder.
Model 3: There is conflicting information
on generator compatibility. Early Aladdin literature on the subject
suggests
that only the #3 generator is compatible with a #3 burner. More
recent literature suggests that the #6 generator will work
fine. The
model 6 wick is readily available as new old stock through used
parts
channels. New Kone Kap mantles heelless chimneys are available.
Models 4, 5 & 6: These lamps are readily
burnable with correct mantles and chimneys available new and
a large number
of old
new stock model 6 wicks and generators readily available.
Models 7, 8, 9, 10 & 11: These lamps are readily
burnable with mantles, chimneys and wicks available new. Model
11 generators are readily available used or as new old stock.
Models12, A, B, C (Nashville), Super Aladdin (#14),
21, 21C 23(UK): These
lamps are readily burnable with flame spreaders, wicks,
chimneys and mantles available new.
Model C made in Brazil: This burner was made
of steel instead of brass and does not work properly. I
suggest not considering one for use as a daily burner. There
are 2 types of knob labeling. One says "Aladdin",
the other says MOD C, Aladdin, IND. BRAS
Model 23 made in Hong Kong: The early
version was slightly oversize and suffered from quality problems
during manufacturing. An
early burner will have a 23 on the knob and nothing else (as
does the #23 UK burner). Some
burners work like a champ, others do not. Parts for new model
23 burners will not fit properly. If looking at an early Hong
Kong model 23 burner to burn, make sure the burner parts all
belong to that burner and are in very good condition.
Later versions
have an Aladdin's lamp on the knob under the 23 and a star stamped
into the side of the burner. The later burners were mostly
good except for occasional out of spec individuals. The
quality of #23 burners seems to have improved since 2000 and
new burners are usually very good.
Parts quality
The Aladdin burner is a precision air metering device and requires
high quality parts to work properly. The quality of parts
is usually excellent for American made parts (1908 through 1963)
and for English manufactured parts. Burners manufactured
in Hong Kong initially had poor quality and were still somewhat
hit or miss through the 1990's. Since 2000 a strong effort has
been made to produce high quality parts.
I have heard that there was a period during the 1970's when wicks
were too thin, affecting fuel flow to the burner. This
has not been verified. Also, wicks were made during the late
20th century that are cut flat at the top and not charred. "The
outer edge of the top surface must be charred or cut back to the
proper angle." " It is a fact that if a reinforced wick
is cut or charred straight across the top, the top surface alone
will
not furnish enough fuel for a full sized flame"* . When
shopping for a new reinforced wick make sure the top is beveled
and charred.
Chimneys made in China (since about 1990) are of abysmal quality,
some not standing right and most with malformed locking tabs at
the base. Made in Taiwan chimneys seem to be weak near the
base and break easily. Since 2000 high quality chimneys have again
become available.
The newer Brazilian made mantles do not seem to last as long as
the earlier mantles. This seems to be an ongoing problem. Mantle
strength seems to negatively affected by storage in a high humidity
environment so it is possible to purchase a new old stock mantle
that quickly decorates with use.
I personally avoid wicks and chimneys using the 1970
and newer italic logo unless I am buying known new stock manufactured
after 2000.
Lox-On chimneys manufactured during the '80s and into the late
'90s are labeled only with the name "Aladdin" in a stencil
like font.
The earlier
ones
that have the
name in
even bold print seem to be of good quality. The later Chinese
version with the name in thin, uneven print should be avoided. The
new Chimneys currently available from Aladdin seem high quality.
In today's market, unless you are looking for a correct period
chimney to match a certain lamp, I suggest
purchasing a new chimney from Aladdin as the most reliable way
to obtain a good quality chimney without having to pay collector
prices.

List of Burner part Interchangeability
(This list is compiled from factory recommendations taken
from Aladdin sales literature plus my own personal experience)
I do not mention models 1 and 2 in the
interchangeability table below because the Cap mantle
is very difficult to find in usable condition and wicks are no
longer readily available that will fit these lamps. These
lamps are not good candidates for daily burning. Late
model 2 lamps came with a model 3 gallery and generator and use
the Kone Kap mantle.
I left the model 3 off the chart because
early parts replacement listings in Aladdin sales literature state
that
newer
generators
are not suitable replacement
for the number 3 generator. However later literature says
that the model 4 through 6 generators will work. If you wish
to try burning a model 3 lamp, parts Interchangeability
is the same as model 4 below.

Model C and Brazil model C galleries are not interchangeable. The
gallery on some Aladdin electric converters that appear to be model
C galleries will not work on kerosene burners.
** This
style of flame spreader is largely interchangeable and appears
the same, but there are slight dimensional differences
in some that may affect the lamp's burning characteristics. MORE
TO COME
*** While
these burners will function properly with all these wicks and wick
holders there are differences that should be noted.
The model 7 wick is an unreinforced type with a long wick holder. Model
8 and the first year of model 9 production wicks use an unreinforced
wick with a very short ring like wick holder. Second year model
9 production, model 10 and model 11 use a reinforced wick that
does not have a wick holder. Model 7 does not have a separate wick
raiser. Models 8 though 11 share the same type of wick raiser.
What all this means is that a model 7 wick can be used in the other
lamps after the wick riser is removed. Model 8 & 9 unreinforced
wicks can be used in all these lamps with the wick raiser. The
Currently available model 11 wick can be used in all these lamps
when the model 8 through 11 wick raiser is present.
~ Some model 23 burners were shipped with slip galleries that
use the heelless chimney. There is also an adapter available
that converts Lox-On galleries to use a heelless chimney.
Making a used lamp ready to burn
Making a used lamp ready to burn is normally just a matter of
cleaning the lamp up, inspecting the parts, replacing any that
are not
in top condition then refitting everything with a new
wick and mantle.
Downloadable Aladdin instructions in pdf format:
The first step is to clean up the lamp
When lamps sit with kerosene in them the kerosene becomes contaminated.
Solid components of the kerosene are left behind as lighter components
evaporate
from the top of the wick. This clogs the wick. Dried kerosene
creates a reddish brown
deposit
along seams
that
tends
to glue
the
burner to the font, the filler cap to the font and the flame spreader
to the inner wick tube.
Before a lamp with old smelly kerosene can be brought back into
operating order the burner needs to be cleaned and the wick replaced.
First remove the burner from the lamp. In some cases this is more
easily said then done. The burner screws off counter clockwise
but can be glued into place by dried kerosene. The easiest way
to unstick a stuck burner is to invert the lamp then immerse the
burner and threads in a container of solvent overnight. If the
lamp bowl is painted clear glass immerse it in kerosene or a household
solvent that does not attack paint such as Simple Green.
Once you can get the burner off the lamp you are ready to disassemble
the burner. I suggest going to the web page for that model of
burner
and looking at the picture of the disassembled burner. This will
let you know which parts come off and what each part looks like.
It will also help you identify a missing or wrong part.
Remove the Gallery:
The first thing to come off if it is still attached is the gallery.
A twist counter clockwise and pull should remove it.
Remove the generator or flame spreader:
The flame spreader sits mostly inside the inner wick tube and
rests on a groove formed into the inner wick tube. The single
exception
being the model 1 generator that sits on a vertical pin inside
the inner wick tube. Flame spreaders are easily removed
if not gummed into place. Usually a light twist to break any dried
kerosene
and
a gentle pull does the trick. Do not apply a lot of force
as the flame spreaders can be fragile.
The best way clean a stuck flame spreader is to invert the lamp
and submerge the flame spreader into a solvent from anywhere from
a few hours to overnight. Both paint thinner and carburetor cleaner
works well. If the burner is also stuck, submerge the inverted lamp
to the point where the threaded burner base is under the solvent.
Flame spreaders are very fragile and easily damaged to the point
where they will not work properly. If it is undamaged care should
be taken during its removal. Sometimes heating the inner wick tube
below the flame spreader with a hot air blower helps break the gum.
Do not use a torch as it may melt the flame spreader around the
holes.
Remove the wick (Model 6 and earlier):
If the burner is model 6 or earlier, the wick will occasionally
stick to the inner wick tube (draft tube). When you remove
the burner the wick and holder may be left behind on the tube.
It the wick stays with the burner, gently pull
on the bottom of the wick while turning the wick adjuster knob
in the down direction. The wick with mounted carrier will come
down together.
If the wick is stuck on the draft tube, use a twisting motion
to unstick it. Most stuck wick will come loose with a twisting
motion. If the wick does not respond to by hand twisting,
soak the stuck wick in solvent for a few hours then twist
the wick. Soaking will almost always get stubborn wicks unstuck.
If you feel a NEED to put something
between the inner and outer tube to pry the wick away from the
tube, think twice. The tubes are thin wall brass and easily bent.
A wet wick will almost always get hung up over a wick tube dent
and the burner will be very difficult to adjust.
Remove the wick (Model 7 and newer):
The wick comes out the top and the wick adjuster comes out the
bottom. How is not all that obvious when you try it the first time.
Unlike the earlier burners, the model 7 and newer burners have a
removable upper outer wick tube that must be removed prior to removing
the wick.
The outer wick tube comes with the air distributor permanently
attached. Before doing anything, look along the outer edge of the
air distributor. You will see an upward pointing flange along the
outer edge. You should also notice three breaks in the flange, two
narrow and one wide. A close examination will reveal inward facing
dimples on the burner just above the flange. There is a single dimple
for each narrow flange and a pair of dimples for the single wide
flange.
The air distributor is a friction fit to the burner wall. Rotate
the outer air distributor by the top of the outer wick tube until
the dimples on the burner line up with the breaks in the flange
then lift.
On model 7 with original carrier: Lower the wick all the
way. Gently pull on the tails of the wick while lowering
the wick with the knob to reduces strain on the gears. The rack
gear is detachable from the carrier. Remove the rack gear and
withdraw it from the bottom. Push then pull the wick and carrier
body up and out through the top. The wick is very fragile and
you will want to push and pull on the carrier if you wish to preserve
the old wick.
On model 8 and early model 9 with original carrier: These
lamps originally used an unreinforced wick with a short mini carrier
attached to the wick raiser. Adjust the wick all the way up. Leverage
the top arms of the raiser off the raised buttons or the wick carrier.
Adjust the wick carrier down and withdraw it from below. Withdraw
the wick from above by holding onto the mini carrier.
On above burners fitted with reinforced wick (no separate carrier)
plus models 10, 11, 12 and B burners: These burners use or were
retrofitted with reinforced wick with built in buttons for the wick
adjuster to attach to. The basic procedure is to adjust the wick
all the way up, prise the adjuster arms off the buttons on the side
of the wick, withdraw the adjuster from the bottom and the wick
from the top.
On Model A, C, 21C, 23 and 23A burners: Both the wick adjuster
and the wick are removed from the top. Adjust the wick all the way
upwards then pull the wick up holding on the the top of the adjuster.
Remove air distributor, model 6 and older:
Removal of the air distributor allows for better cleaning and
provides access to the adjuster gears in case repairs are needed.
The model 1 uses a stamped metal air distributor that is a friction
fit. Usual a quick twist to loosen it and a gentle pull removed
it. Models 2 through 6 use metal screen air distributors. They
rely upon a spring pressure from the flange to hold the distributor
in place. The screen needs to be prised up from the burner. I
have a scribe tool I purchased from the hardware store that is
a rod that tapers to a point and makes a sharp right and turn
at the tip. It lets me insert the bent tip into a hole and lift.
Cleaning the lamp:
Metal lamps and burners: The dried kerosene and dirt can
be cleaned by soaking in a solvent and brushing. I keep
my old tooth brushes for lamp cleaning. Finish off by washing
with a non petroleum solvent like Simple Green or dish
soap and
water.
Rinse
and allow
to dry
completely
before reassembly (Use a hair dryer or an oven with the door open
if you are in a hurry).
When dealing with real grungy stubborn deposits, such as generators,
I tend to use a phosphoric acid solution (Found in auto parts stores
to
clean
bare rust free metal just prior to painting). Most soft drinks
have a high level of phosphoric acid and work well as metal cleaners. Vigorous
brush scrubbing in a bath of this solution usually gets metal parts
clean and sparkling like new. You do not want to soak a part
in the solution for very long and you want to wash the part with
running water and let it soak a while to be sure every bit of the
acid is off. Any acid left will start oxidation. Wear
rubber gloves and eye protection if you try this.
If you wish to polish parts be very careful of buffing wheels.
Some are too aggressive for the thin brass. White rouge
works well as a buffing compound on a muslin buffing wheel. "Never
Dull" is my favourite polish for plated lamps.
Glass Lamps: Always use water close in temperature
to that of the glass. Thermal stress frequently breaks glass
lamps. This is especially true of the early model B glass
lamps. This
also means do not pour near freezing kerosene from outside into
a room
temperature
glass
lamp. Dish washing soap works well on glass lamps. Alternatives
are Simple Green or any non abrasive glass cleaners with degreasing
action.
