To obtain full benefit from the WA 41 A and
trouble free operation, read the following in-
structions and information carefully.
DESCRIPTION AND FUNCTION
* The control panel incorporates a
switch, a locking device for the fuel and a
pilot light.
* The electric pump motor drives the fuel
pump, which is positioned in the tank.
* The fuel pump delivers fuel to the com-
bustion dish and is controlled by means of
the button above the control panel,
At position low, the consumption is approx.
2,5 l/h. At position high, the consumption
is approx. 4,3 l/h.
One and another depends on viscosity.
* The main fan is controlled by a thermostat.
As soon as the combustion chamber has warmed
up sufficiently, the fan starts to operate.
* The burner is equipped with an air intake
fan to supply air for combustion. This air
combustion fan stops when the flame has
extinguished. Pipes φ 200 mm can be
connected to this fan so that the combustion
air can be sucked from outside the area to
be heated.
* Most types of waste oil can be used, such as
gearbox oil, gas oil, diesel oil, hydraulic
oil, HBO 1, 2 and 3, but not those with a
high viscosity, such as SAE90.
DO NOT USE TRANSFORMER OIL WHICH MIGHT
CONTAIN SUBSTANCES DETRIMENTAL TO THE
PERFORMANCE OF THE BURNER (PCB)
* When the pump motor stops, the flame will
extinguish once the fuel in the burner dish
is exhausted.
WARNINGS
1 There could be a possible danger of
explosion if the burner is reignited while
it is still warm.
2 There must be sufficient air for combustion;
make sure that the combustion air intake fan
is never blocked.
3 Modifications made to the burner by dealer
or end user, invalidate the manufacturer's
warranty.
INSTALLATION
* For installation, consult the local
prescriptions.
* The burner must be installed on a completely
level, concrete floor.
* Check that the chose position presents no
problem for:
- electrical supply 230V/2Amp.;
- flue pipe installation;
- combustion air supply.
* Open the top cover of the burner and remove
the cover of the combsution
chamber.
* The following items are packed within the
combustion chamber:
1x T-piece with built-in draught stabiliser
for flue pipe connection
1x cleaning shovel
1x scraping tool to remove residue from
combustion dish
1x combustion dish
2x burner ring
1x spare card to seal the bottom of com-
bustion chamber
2x handle with bolts
1x pedal
FLUE PIPE
For clean and trouble free combustion, it is
essential that the flue pipe is installed correctly.
a. minimum diameter of flue pipe: 150mm
b. check that flue connections are well sea-
led
c. minimum flue height: 5 m
d. the wind must be able to reach the top of
the flue from all directions (e.g.: it may
be necessary to extend flue above roof
apex)
e. all pipes should be vertical if possible,
keep horizontal pipes to the absolute
minimum
f. avoid bends in the flue installation if
possible but if unavoidable e.g. if flue
has two bends because of installation
through a wall or window, then:
1. the pipe should be as high as
possible within the building
2. flue pipe outside the building
should be insulated (double
walled)
3. the minimum height of the flue
has to be increased to 7.5 m to
compensate.
