Mains Connection - Master BLP 33 E Operation And Maintenance Manual

DESCRIPTION
This hot air heater is liquid propane gas fi red. It is character-
ized by the total use of the calorifi c power of the fuel, due to the
thermal exchange between the air and the combustion products.
The machine complies with EN 1596.
WARNINGS
• As this machine needs an adequate change of air, it must be
used only in the open air or rooms with an assured and con-
tinuous change of air. For installation they are valid the national
norms in force, included technical norms and fi re and accident-
prevention regulations.
• The appliance must be used only as hot air generator, following
precisely these instructions
• It is very dangerous and absolutely forbidden use the appliance
in "Basements" or underground
• NOT TO BE USED FOR HEATING HABITABLE AREAS OR
DOMESTIC PREMISES
• In case of gas smell, there could be dangerous leaks. Turn off
immediately the appliance, close the cylinder and cut off the plug.
Than call the technical assistance.
• When the appliance is stored or not in use, be sure that the fl ex-
ible hose will not be damaged (plied, bent or twisted).
• Place the gas cylinder in a protected position behind the appli-
ance. Make sure that no objects obstruct the fan air intake.
• Connect to electrical mains equipped with a "life-saver" switch.
• Never, for any reason, reduce the size of the air outlet open-
ing.
• Safety distances: 2 metres from walls or objects.
• The mobile generators may be used only on fi re-proof fl oors.
• Do not use the generator in rooms containing explosive pow-
ders, gas fumes, liquid fuel or infl ammable material (cloth, paper,
wood, fuels, etc.).
• Any maintenance or internal cleaning jobs may be performed
only by specialised personnel authorised by the manufacturer.
• If the appliance cannot be left in a safe condition, it must be
made unserviceable (e.g. seal the gas inlet point and remove the
power plug).
• If the application does not ignite or if ignition is faulty, before
making a further attempt, check if the fan is blocked and/or if air
circulation is suffi cient.
• In any event, have the appliance checked once a year by spe-
cialised personnel.
• Improper use of this hot air generator will cause injuries or risk
of death by burns, fi re, explosions, electrical shock or poisoning
by carbon monoxide.
• Do not connect tubes to channel hot air!

MAINS CONNECTION

Before connecting to mains, ensure that the voltage and fre-
quency are correct.
The mains connection has to be made according with the na-
tional norms in force.
Before carrying out any repair or maintenance operations, al-
ways disconnect the power supply cable.
FUEL
Fuel: use propane gas (G31) or butane gas (G30) only.In any
event, only use gas in I P and I

CONNECTION AND CHANGE
OF THE GAS CYLINDER
Cylinder shall be changed in open air, far from heating sources
or free fl ames.
In case of substitution of the gas hose, use only types listed in
the components list or certifi ed types for this particular use.
Connect the pipe to the generator input union, and then con-
nect to the gas cylinder in the following order: pressure reducer
(complete with safety valve) and gas hose.
Keep in mind that junctions have a left thread, secured by turn-
ing in an anti-clockwise direction. Make sure that the rubber ring
is present between the reducer and the cylinder (should the type
of connection require one). Check the tightness of the joints by
pouring some liquid soap over: the presence of bubbles is evi-
dence of gas leak. It is possible to connect a number of cylinders
together for greater autonomy.
The supply pressure is provided by the pressure regulator sup-
plied as a standard item, and corresponding to the technical
specifi cations table.
Only the following accessories can be used to connect the cyl-
inder:
• Flexible hose for liquid gas DK6.
• Liquid gas pressure regulator complete with safety valve.
BURNER'S OPERATING CHECK
After ignition, burner operation can be inspected by looking at
the fl ame at the hot air outlet. The fl ame should be completely
and uniformly burning and does not lift or pull away from the
thermocouple.
IGNITION FOR ELECTRONIC
TYPES ...kW
If the room thermostat is off, the sensor start the analysis. After
a few seconds the fan starts working and, when the safety time
TS is over, the burner will start working. At the end of the safety
time TS, if there is fl ame, the system will be in function. If there
isn't the fl ame the system will be in nonvolatile lockout. Before
B/P categories.
