USE OF THE BURNER
1. If you need, place the wax conteiner (look at the
"Accessories" section) upon the flame nozzle (A).
2. Turn the air flow regulator (B) until the circular hole
is completely open.
3. Open the main stopcock of your gas supply.
4. Then, press the knob of the gas tap (C) downwards
in order to unlock. Then apply a ¼ turn until it is
parallel to the central axis of the burner.
5. Bring up a flame to the nozzle (A). The burner
should immediately light up with no problem.
6. You can use the regulator (B) to adjust the airflow.
By opening the regulator completely, you will obtain
a flame with a blue base and a bright yellow tip.
Length and bright will be constant with no altera-
tions. This kind of flame means that combustion is
perfect and the gas supply is optimum.

If you use the regulator (B) to shut the airflow
off, the blue color will eventually become red-
dish, meaning that combustion is lacking oxy-
gen.
Under extreme circumstances, when the airflow
is too low, black smoke (unburned) may appear.
This situation should always be avoided, sin-
ce the resulting gases are extremely dange-
rous.

First make sure that the gas mains stopcock has
been shut off completely. Use a cloth soaked in
soapy water to clean the unit. Never use alcohol

dentally fall through the orifice in the flame
nozzle (A). Wax accumulating inside the nozzle
elbow may cause obstructions and impair burner
performance. Should this occur, proceed to re-
move the wax as follows:
 Close the main stopcock.
 Release the nut of the hose from the con-
nection fitting (D).
 Once the burner has been disengaged
from the main supply, apply a ¼ anti-
clockwise turn to the flame nozzle (A).
 Apply a flame to the nozzle elbow to melt
the wax accumulated inside. Tilt the burner
to allow the wax to flow out freely through
the flame nozzle (A).
