General provisions
Using
The air heater (hereinafter referred to as the heater) is used for heating the cabin of motor vehicle box
bodies, cabs of machines, caravans, stationary units, yachts, etc. in the regime of recirculated air or with
the ventilate air from the surrounding area..
PROHIBITED
The heater is not intended for continuous heating e.g. living space, garage or cottage. The heater is not
further intended for drying or blowing animals or objects with hot air.
The heater is not allowed to be installed in vehicles that are subject to regulations on transport of
dangerous goods ADR, TRS 003, TMD.
CAUTION!
When mounting the heater, it is necessary to follow the instructions for installation contained in this service
book. Buildings incl. the heater warranty is only possible to have done heater producer or authorized
service. Otherwise, the user loses all warranty claims. And even if the authorized service when installed or
repaired the heater grossly violated the rules set by the producer and the changes did not consult with the
producer ahead.
To ensure proper function the customer must be thoroughly familiar with service and heating function
(service worker gives the instructions for the operation of an independent heater to the user) and the heater
must be operated only as directed.
When solving installation, it is necessary to respect the provisions of the relevant standards relating to fire
protection during installation and using heating appliances.
After the lifetime the heater must be discarded appropriately.
OPERATIONAL SAFETY

In area of filing station or fuel deport the heater must be off to prevent the explosion. Also in areas
where combustion fumes or dust (fuel, coal, wood or corn dust, etc.) generate, the heart must be off
due to the danger of explosion

It must always be ensured that the program preselect ion cannot switch on the heater, especially in the
area where it is not allowed central heating (gas station, garage, underground parking, where is a
potentially dust or flammable vapors)

Always and in any circumstances, use only original parts supplied the producer (BRANO a.s.) and
approved by the appropriate standard.
Description of the device
The independent heater is a heating device that that heats the air using heat released by combustion of
diesel fuel and its heat output is infinitely adjustable. To this heater it should be ordered separately
components for proper function, i.e. the pump, harnesses, intake silencer, exhaust and parts needed for
installation of the heater in a vehicle. Electrical installation is made of 12V / 24V. The main parts of the
heater are: aluminum exchanger, combustion chamber, electrical motor with fans of heated and
combustion air, covers, flame sensor, overheating fuse, glow plug and control unit with a temperature
sensor of heated air. The heater is controlled by a timer or a manual control, which are not part of the
heater assembly and must be ordered separately too.
Description of function
After switching on, the heater passes through the test phase, which checks on the function of the important
electric circuits. For about 10 seconds the fan is made to turn. The start phase begins with ignition of glow
plug for 30s. Then the motor gradually starts rotation and simultaneously starts the fuel pump. In the
combustion chamber the glow plugs ignites mixture of a fuel with combustion air. Hot flue gases flow
exchanger and heat the flame sensor. The control unit after reaching the required temperature cuts off the
supply to the glow plug. Burning then runs automatically. When the first start is not successful, is followed
by second start automatically. When even this does not succeed, it is regarded as an error "failed start" and
heater is switched off after airing. This start phase is indicated by flashing symbol
on the controller. At a
time when heater reaches the combustion temperature, the symbol stops flashing and remains lit

continuously. Heating air is warmed by the heat exchanger walls and flows into the heated space. The
heater can be set to regulate on the performance or on the temperature by using the controller. When
controlling for performance using control sets the desired power. When controlling temperature the
performance is regulated by setting of the temperature. This regulation means that the heater is switched
off when heated space is overheated. Then the fan runs only. The heater is switched on again after falling
below the set temperature. The heater operation at a reduced speed (i.e. rolling speed) is indicated by a
flashing symbol
on the controller. The heater after turning off vents (max.6min). During this time (i.e.
Deceleration) the exchanger is freed from the rest of the flue gas and cooled to about 80°C. Then the
electric motor switches off. Deceleration of the heater is indicated by flashing symbol
on the controller.
In the event of a fault in the heating function is displayed E: number of the fault and flashing red LED on the
controller (see error messages).

Remote control and GSM control
Remote (wireless) or GSM control can be connected to the independent heater BREEZE IV, IV and WIND
ATESO ALFA, but only to the switching timer or the manual control. The heater can be controlled using the
module GD-04 David heating via mobile phone. Advanced GD-04 David can also be controlled with a
remote control. Connection diagram is in the picture.
Connection to the control - output relay of a module GD-04 is connected to a 2-pin connector for an
external switch on the timer or the manual control. In this case, it is possible to start the heater in the same
mode, which is set to the timer or the manual control
INSTRUCTIONS FOR INSTALATION
The heater
The heater can be mounted to horizontally with vertically downward exhaust (e.g. floor mounting of the
heated space or also in the vertical position, exhaust and air intake are positioned in a common horizontal
plane (e.g. wall mounting of the heated space). It is also possible to mount the heater in the range 0°- 90°
between said positions. When mounting in other than horizontal position it should be ensured that the glow
plug is always upward (see Fig.). Glow plug should always be easily accessible. Heater is intended for
installation in the passenger compartment or cargo, or in a special sealable cabinet outside the heated
space. Installation of the heater is performed on a prepared flat surface with the appropriate holes (see
drawings in annexes) and this is mounted in four nuts. Straightening of undulating surface on which the
heater is mounted should be made by shaking toward the heater.

Heating air
Air ducts - if needed - must be made as short as possible with the lowest number of bends. Their caliber
along the whole length must not be less than 55 mm and it is advisable to make the bends smoothly. If it is
inevitable to change a duct section from a circle to square, the opening must be increased at least by 50%.
If a suction duct or a distributor duct is terminated in a higher number of holes (e.g. a grid), the sum of the
sections of these holes must not be less than the caliber of the duct.
The intake and the outtake of the heated air must be situated so that the hot air cannot flow directly back
into the heater. It is advisable to provide the ducting with a thermal insulation, especially the parts going
outside the heated area.
The surface temperature of the immediately accessible locations and distributing output channels must not
get over +70°C, at metals and other materials +80°C (E/ECE/324-121 requirement of Regulation No. 122,
Annex 5). Therefore, the distributing output channels must be protected by a cover or insulation.

Combustion air
It is necessary to install an intake silencer at the input of the combustion air. The combustion air must not
be sucked from the passenger’s or crew’s compartment. The intake port of the combustion air must not be
orientated in the direction of the driving motion and must be positioned so that it prevents clogging with dirt,
mud or snow. In case the suction port is situated in a place where its clogging with dirt might occur (e.g. in
the wheelhouse), it is necessary to use so-called intake silencer extension and situate the intake silencer
itself in a safe place. The original part - intake silencer extension – is 1 m long but it is possible to cut it
short in accordance with needs. The whole suction piping from the inlet to the heater must be laid with a
constantly rising gradient. If this condition cannot be met, it is necessary to make a 3mm hole in its lowest
point, so that the water or condensation could drain away.
The throttle valve of the combustion air on the heater is factory set and it is prohibited to manipulate it
anyhow. It is also prohibited to dismantle the sealed part of the heated air ventilator.
Flue gases
Flue gases must be reliably diverted to places where they cannot be part of the heating or combustion air.
The heater exhaust must always be fitted with a flexible tube that can be ordered separately. This tube can
be reduced to a minimum length of 0.5 m, respectively can be extended with pipeline with a minimum
clearance of 20 mm of 1 m. Its end must be equipped with a tailpipe. Exhaust pipes should be fitted with a
small sustained gradient towards the outlet flue gas. If this is not possible, must be drilled draining holes
around - 3 mm in the lowest places, so that water and condensate can freely drain off.
The flue gas outlet should be oriented so that is not directed against the driving direction and preventing to
its clogging with mud or snow. It is also important to ensure that the flue pipe did not exceed outline of the
vehicle and jeopardize the function of important parts of the vehicle (fuel lines, brake hydraulics etc.). It is
not appropriate to attach the exhaust pipe to the plastic parts of an automobile; the exhaust pipe
temperature can reach 200 ° C. If the end of the exhaust is less than 50cm above ground level, make sure
that the end of the exhaust not be oriented perpendicular to the road, and thus prevent flue outlet towards
incendiary substance (dry grass, straw, sawdust, etc.). Instruct the user in this fact.

03-9940.186
The fuel supply
It is necessary to use the appropriate fuel to establish a reliable function of the heater in the whole
temperature range. It is possible to use any fuel oil at the temperatures over 0oC, winter diesel oil down to 20o C and a mixture of the winter diesel oil with kerosene or petrol at the ratio of 1:1, or special arctic diesel
oil alternatively, under -20oC. It is necessary to solve the fuel system with regard for capacity of the fuel
pump. It is also necessary to avoid installing any part of the fuel system near a source of heat (the exhaust,
the radiator etc.) and to assure that it cannot collide with any moving part of the chassis (suspension or the
axle). The fuel piping from the pump to the heater must not incline and underpressure should not arise at
the collection place of the fuel (fuel tank, pipes). It is recommended to use polyamide hoses with the caliber
about 2 mm for the fuel supply line and to use only rubber hose unions to connect them. The hoses have to
be cut even, without burrs or deformation and their ends have to be pushed close to each other inside the
connecting hose so that air bubbles cannot form there. Cut the hoses with a knife (does not use wire cutter,
shear or saw).
Prevent the formation of air bubbles
Regulation of fuel standards:
 Diesel EN 590

BIO diesel ČSN 65 6509 (containing up to 5% rapeseed oil methyl ester)

Light heating oil
Pump
The pump must be mounted on a vehicle using a spring washer (silent block), which is part of the kit. It
must also ensure a certain position of the pump (see fig. below) to prevent its spontaneous aeration.

Fuel take-off for heating operation in practice is possible by three ways.
1. Taking the fuel from the vehicle tank by a needle
This is the most suitable and recommended method of fuel takes-off. This way may be used with all means
of transport, powered by a Diesel engine and it is recommended for vehicles whit turbocharger, where is
used an additional pump in the tank of a vehicle in which happen an overpressures in the fuel system of
vehicles (TDI,HDI,atd..) The fuel flow is not affected by the running engine. It is necessary to fit the length of
the fuel needle so that its end is approximately 20 mm over the bottom of the fuel tank. Its lower end must
be beveled.
The service book IV / ALFA

03-9940.186
2. Taking the fuel from an extra fuel tank
It is necessary to use an extra tank where there is a petrol engine (e.g. with caravans, cabins etc.) and also
in the two above other cases, when the suction lift could exceed 1 000 mm during operation. It is advisable
to install an extra fuel tank as soon as the suction lift reaches over 500 mm. The additional fuel tank must
meet the directive 70/221/EHS and is subject to the approval of a government appointed test laboratory.
3. Taking the fuel with a branch at the fuel line of the vehicle.
This way can be only used in must vehicle built in where it is possible none of the above methods of
assembly and having fuel piping of outside diameter 10 mm max. The reduction socket must be connected
to the vehicle fuel line between the tank and the fuel pump (in front of the fuel filter). It is not possible to
mount it at the overflow pipe
Needle into the tank
Tank needle is intended for installation in plastic or metal tanks of the vehicle. For plastic tanks it must be
installed at reserved places (with thickness of the tank wall). If it be drilled the hole in another location, tank
could crack. The needle must be placed only on upper horizontal surface of the tank.

MEASURING INSTRUMENTS
For diagnostics and service of the independent air heater BREEZE IV, WIND IV a ATESO ALFA it is
necessary that the service was equipped with these meters and instruments: the program LIN-bus and the
tester of underpressure of air discharge
The tester of underpressure of air discharge
The service book IV / ALFA

03-9940.186
Tester underpressure of the blower BREEZE
INSTRUCTIONS:
1. Discharge can be measured on the heater in any prescribed inbuilt position.
2. It is necessary to remove the exhaust pipe distribution of heating and air intake silencer from the
heater. In the case that the exhaust pipe cannot be removed, the vacuum level is of 1% less (at
the length of the exhaust pipe 1 m).
3. Mark the position of the baffle for combustion air before measurement and then open it fully
(vertical position, see picture). It is necessary to turn the baffle at its original position after the
measurement
-1
4. Measurement is taken in ventilation mode and maximum speed (speed 4920 min ). Time to
stabilize the pressure value is 10 minutes.
5. Connect the test pipe piece provided with a branch for scanning static pressure, to the combustion
air intake socket. Test pipe piece have to be in direction of heater’s axes (see picture). Disconnect
the hose (length shall be 1m) to the pressure gauge just close before reading the values and
calibrate the gauge by pressing its right button. Then connect the hose again and read the value
after about. 30 s.
6. The underpressure in the test pipe should be 600 – 780 [Pa].
7. Alone subassembly must be clamped horizontally in a vise. The measuring tube must be along
the axis of the heater (see Fig.). Measured values at 5000 RPM should be 650 to 790 Pa.
8. The tester must be calibrated 1x per year at an authorized laboratory or directly in BRANO a.s
