INSTRUCTIONS for the care and operation
of the
BK Saf-e-fire
BLUE FLAME
HEATER.
First handling :
Remove packing and make sure that the perforated flame spreader is in the right
position on top of the wick tube and pushed down home.
Filling :
Unscrew filler cap and fill the container with a good quality paraffin. The
container holds one gallon, but do not fill right up to the filler opening. Wipe off
any spilt paraffin and always keep container clean. When filling the container
for the first time, make sure that it is at least three quarter full. The foolproof
indicator will always show how much paraffin is in the container. The float
painted in red and white, rises and sinks with the fuel level.
Under no circumstances use petrol or benzol. Never mix any other fuel with the
paraffin or add anything to it.
Replace filler cap by screwing clockwise. Make sure it is fitting tightly. The
packing ring in the screw cap seals off the opening completely.
The container can be refilled whilst alight, provided this is done carefully. This is
quite safe.
When using the heater for the first time the tank should be filled an hour
beforehand, so that the wick can get well soaked with paraffin. The wick only
obtains its full soaking capacity after approx 12 hours. Once the wick is well
soaked, it can always be lit immediately after the container has been filled.

Lighting :
Raise the wick by turning
carrying handle or regulating
collar clockwise until the
wick is approx. 1/8" (1/2
cm) above wick gallery
flange. Generally two
complete twists will be
sufficient but always check
when the heater is opened.
If the wick is raised too high,
a large yellow flame will
result, which must be
immediately reduced until it
is blue.
The chimney assembly can
be lowered by pressing
lightly on spring clip. Light
wick all-round and close top
of heater. Check that spring
catch is fastened.
1/8" (1/2 cm)
Do not raise the
Wick higher.

Regulating :
When the wick is fully alight,
the flame can be adjusted by
turning carrying handle or
regulating collar clockwise or
counter-clockwise.
Important :
One of the striking novelties
of the BK Saf-e-fire Flame
Heater is, that the wick
movement is not controlled
by a regulating spindle, but
by an ingenious interlocking
device, which enables the
flame to be adjusted simply
by turning the carrying
handle or regulating collar.

Caution :
The BK Saf-e-fire is a Blue Flame
Heater. The flame should always be
blue. When the heater is burning in
low, medium or high position, the
flame must be blue and transparent
as shown here (A).
If set Too High, yellow streaks will
appear resting on the ridge of the
round blue flame, as shown here (B).
If set Too Low, the flame will be
wholly or partly yellow, as shown here
(C).
The user should thoroughly
familiarise himself with these flame
pictures became the heater must be
adjusted within the limits shown. If
the heater is used in a dusty
atmosphere, dust particles will be
sucked in by the burner and burned
with the oxygen. Minute reddish
yellow sparks will shoot up then
above the blue flame. These are
harmless.
Extinguishing :
Turn the chimney assembly counter-
clockwise by means of carrying
handle or the regulating collar until
the flame dies down, 2 or 3 twists will
normally suffice.
It is not necessary to blow flame out.
When relighting observe the above
instructing. The heater will reach its
maximum output within a minute.
A. Correctly Adjusted
B. Turn wick down until streaks
disappear
C. Turn wick up until a completely
blue flame is obtained

Wick cleaning :
When in continuous use, the wick should be scraped approx, once a fortnight
with the wick cleaner provided. The carbon or chars formed on the wick after
continuous operation can be removed by scraping the wick top.
Remove flame spreader before placing the scraper on top of the wick. Pressing
gently, rotate the cleaner until no more carbon is coming through the holes of the
cleaner. Any remaining deposits can best be removed from wick or gallery flange
by wiping carefully with a cloth.
Never use scissors, razor blades, etc.
Burning dry :
In case the container should not have
been refilled in time and the partially
dry wick will start glowing, the heater
should not be extinguished nor the
container be filled, but the tank
should be allowed to burn completely
dry.
A yellow-red flame instead of the
normal blue one is the danger signal
that the container is burning dry and
the wick itself is glowing. When the
tank is allowed to burn completely dry,
the wick-edge will burn off evenly and
the wick can be scraped and reshaped
as described under, Wick cleaning.
The wick is now ins perfect condition
again, but after filling the container,
wait an hour before relighting. Failure
to observe these instructions will cause
a flame with yellow spiked resulting in
a reduced heat output and posibly
some odour. Watch the indicator
therefore and fill the container
regularly. Avoid burning dry.

7
Inserting new wick :
The effective burning length of the wick is approx. 2 3/4"(7cm) which ensures, if
treated correctly, a working life of two years under normal conditions. When a
replacement ultimately becomes necessary, it is recommended to allow the
container to burn dry. This will avoid spilling of paraffin and odour. It will be
found convenient to place the heater on a table when fitting a new wick.
Now adopt the following procedure.
1) Turn chimney assembly by means of carrying handle or regulating collar
counter-clockwise until the wick and wick carrier are free from the gallery. 5 of 6
complete twists will suffice.
2) Unscrew the two nuts from fastening ring.
3) Lift chimney assembly from container, leaving wick exposed. If by mistake the
wick and wick carrier have not been turned down far enough, these will remain
screwed on to the gallery when the chimney assembly is lifted. Simply screw off
wick and wick carrier by turning anti-clockwise.
4) Remove flame spreader and pull off worn out wick with wick carrier from
central tube.

8
5) Push wick carrier over new wick as shown here: Make sure that the stud on
the wick carrier is placed between the slits of the new wick and protrudes freely.
6) Replace flame spreader on central tube and place new wick and wick carrier
over the central tube in such a way, that the stud of wick carrier will be above
the groove in the central tube.
This pressed-in groove is directly visible from the direction of the filler cap. First
push wick carrier stud over the edge of the central tube and pull down wick at
the opposite split end until the wick carrier stud slides into the groove in the
central tube.
Take care, that the yellow tape inside the wick is not damaged. Replacing the
flame spreader before the new wick is inserted, will minimize this risk.
7) Check by pushing wick up and down that the wick carrier stud engages the
groove in the central tube. This is imperative because otherwise the wick will
turn. In this position the wick should be pushed freely upwards by the pressure
of the spiral spring round the central tube. If because of the newness of the wick
there is too much friction. press the wick carrier all-round against the central
tube until wick and wick carrier shoot upwards by the spring pressure.
8) Replace the chimney assembly with wick gallery over the wick and push
downwards until the fastening ring slides on the screwed studs and screw on
nuts firmly.
9) After turning up the wick, the heater is ready for use again but the tank should
be filled an hour before relighting.
This operation is simple and when attention is paid to the above instructions,
need only take a few minutes.

CAUTION :
Only the genuine BK wicks should be used. If there should be any difficulty to
obtain these wicks, please communicate with us.
Wick raising :
The wick can be raised several times before replacement will become necessary.
When the wick can no longer be turned approx 1/5" (1/2cm) above gallery
flange, the wick can be raised quite easily. Remove chimney assembly from
container as just described. Pull off wick and wick carrier from central tube and
push wick carrier approx, one inch downwards. Take care, that also now the wick
carrier stud is placed between the slits of the wick. Replace wick on central tube
and the chimney assembly on container as described above.
Take care that the wick carrier sits square on the wick.

10
Replacing glass cylinder :
In case the glass cylinder is damaged or broken by very rough handling,
replacement is necessary.
Obtain a new cylinder through the original supplier of the stove. Open heater and
take off the burner basket fitted in the lower part of the chimney. This is a push
fit only and the basket is not screwed on or specially fastened. Remove the
enamelled part of the chimney by unscrewing the six screws which fasten the
three steel supports to the enamelled upper part. Insert new cylinder and screw
on again the supports to the chimney upper part. See to it that after fitting the
glass chimney will be free and not tight, otherwise there is the risk of cracking.
After replacing the burner basket, the heater is ready for use again.
The cylinder is made of heat resistant glass and proof against cold water
splashed and cold air draughts, even when the flame is in the highest position. If
there should be any trouble to obtain a new cylinder, please communicate with
us.
Care and upkeep :
After continuous burning for some length of time, a dullish film may develop on
the enamelled part of the chimney and the glass cylinder. This film can be easily
removed by using a cloth and some soap. The chimney can be cleaned from the
inside by opening the heater and taking out burner basket.
Storage :
When the heater will not be used for a long period, e.g. during the summer
months. It is recommended to empty the container.
