On pressurising the fuel tank,
Paraffin, (kerosene), is forced from the fuel tank
through control tap and into the vapourising tube. The
vapourising tube is pre-heated by methylated spirit,
(alcohol), in a torch cup clipped around the tube.
A fine spray of hot paraffin leaves through a fine jet at the
top of the vapourising tube and on entering the mixing
dome vapourises into a gas. Air mixes with the gas and
the mixture leaves the burner through a ring of holes, it
then passes into the mantle which is suspended below.
Inside the mantle the gas burns and causes the mantle to
glow with a bright white light. As the vapourising tube passes through
the centre of the mantle the heat from combustion
continues the process started by the pre-heater torch,
this feature also gives a clear shadow-free light.
Inside the vapourising tube is a cleaning needle which
'pricks' the jet every time the lamp is turned off.
Should the jet block in use it can be cleared by quickly
turning the lamp off then on again. A match should be
kept at hand should the lamp fail to re-light.
This vapourising principle also applies to other
paraffin, (kerosene), lanterns manufactured by other
companies such as Vapalux, Bialaddin and the 'swan neck'
lanterns such as Coleman, Optimus, Magnalux, Anchor,
Tilley PL53 Lantern, Pre-War
procedure for the Tilley Stormlight is as follows:-
1) Make sure lamp
is turned off.
2) Unscrew pump and ensure there is sufficient paraffin
in the tank, approx. half full, replace pump.
3) Should you be re-lighting the lamp and know there is
sufficient paraffin in the tank, always loosen pump to
release any pressure present then retighten pump.
4) Ensure mantle is in good order, (see 'fitting new
mantle' if absent or damaged)
5) Soak preheater torch in methylated spirit.
6) Clip preheater torch around vapouriser stem, light and
slide up under glass.
7) LEAVE THE LAMP ALONE!!, don't fiddle!, when the
methylated spirit begins to burn down give ten to twelve
full strokes on the pump.
8) Just before the methylated spirit goes out, turn on the
lantern and the mantle should light with a gentle 'Pop'
and give a slightly yellow light.
9) Allow to burn for 30 seconds or so then give several
strokes on the pump, (up to forty), until the mantle is burning bright
white and the lantern gives a steady hiss. Over-pumping
will cause yellow flame outside the mantle and can damage
To extinguish the lamp simply turn the control
Older models have a small 'nipple' on the tank, if
working, (and they seldom did), a rod will rise
flush with the top of the nipple when pressure is
correct. If the light begins to fade or the mantle strongly 'pulses' light give additional strokes of the pump to
the mantle by springing the lantern handle slightly apart
and lifting off the enamelled hood. Ensure all of the old
mantle is removed, especially any 'string' in the groove
around the brass burner body.
Fit the new mantle by sliding the larger opening over the
spigot and stretch it into the groove around the burner
body. Then stretch the smaller end into the groove at the
bottom of the spigot.
Arrange the fabric of the mantle evenly around the burner
to ensure correct shape when the mantle is burnt. Replace
enamelled hood back on the lantern ensuring the
vapouriser tube passes up into the centre of the spigot.
When the spirit torch is applied for the first time after
fitting the new mantle will burn and smoke. This is
normal, after burning the mantle will have the property
of white ash and is very fragile, DO NOT TOUCH!
With practice it will take less time to light your lamp
than read these instructions!.
