There is an envelope inside the unit containing the Instructions for Installation and Servicing, User’s Guide use and Guarantee and ser-
vices and the warranty documents.
The appliance operates based on direct heater principle, that means the heater air is blowed into the heated room directly for assuring of
requested temperature. Besides HEATING (winter) mode the appliance can achieves the VENTILATION of room as well (summer mode).
Principle: The warm air blower appliance burns up the sucked mixture of combustion air and gas (S-,L-,Propan or natural gas), in this
way making the heater air,which is blowed into the heated room (by direct blowing or through air duct) in order to ensure the keeping of
temperature on requested value.
The heating and consumption values to be found as per appliance and gas types in the enclosure 1.b.
The supply of combustion air of appliance can be realized in two ways:
• directly from the heated place (A,C)
• from open air (CL), it can be used in case of such plants, which are working with dangers materials as follows: painting work-
shops and workshops,which are using explosive or corrosive materials etc…
The combustion products fl ow through the exchanger pipes towards the fl ue system while heat up it, parallel with this process the blower
fan circulates the sucked inside or outside air through the heat exchanger assuring the needed warm air for heating. (the heater air is
average 50°C)
The air supply of blower fan can be solved in two ways:
• by direct sucking in from the heated place (A, C, CL types),
• by sucked in from outside (CL type).
The made warm air can be passed into the heated place in two ways:
• by direct blowing in through the leading lamellas (A, C types),
• by blowing in and leading through air duct to the demanded places (in this case there are no lamellas on the device).Such as
the C and CL type of GTV-E.
The technical data of appliance can be found in the enclosure 1.

The GTV-E air heater operates with reduced NOx emissions in accordance with EU Regulation 2281/2016, which entered into force on
1 January 2018. Nitrogen oxide emissions from gas-fueled air-heaters under this Regulation shall not be higher than 100 mg / kWh. This
section of the regulation is compliant with the GTV-E type of GTV-E air heaters. The Declaration of Conformity can be downloaded from
our website (www.pakole.com) and found on the last pages of this Instructions for installation and servicing.
R NO
The technical solutions for the development of GTV-E with a reduced NOx emission air heater appliance:
- NOx reducer placed in a fl ue pipe
- pressure compensation plate placed in the fl ue gas chamber
- a blower fan with increased air fl ow
These supplements prevent the creation of favorable conditions for the formation of NOx which are the result of the formation of fl ame
and high fl ame temperatures and the long residence time of the molecules in the fl ame during combustion.
ATTENTION!
During regular maintenance, service technicians must check the status of the NOx reducers (physical
damage, dirt, lack of material, etc.) and must measure the value of carbon monoxide emissions. If this
value is above 200ppm, the replacement of the NOx reducer elements is compulsory !!!
The overal dimension of appliances are in enclosure 2.

The properly installed appliance according to the control sign received from temperature regulator - in the present case heating – starts
the exhaust fan,which executes the 30 seconds prepurge time. This time period is also enough for biggest power appliance to ensure
the satisfactory air exchange namely the triple of combustion air volume. When the ventilation happened the sparking is started and the
dual magnetic valves are opened the gas ignites.
If the continuous burning is formed within 5-10 seconds the appliance is operating normally the green control lamp is lighting..During
operation the appliance continuously monitors the status/sign of diff erential pressure switch and fl ame detector, if needed the electronic
control intervenes in the process.
If the status of diff erential air pressure switch is changed during operation namely switches over from work/switched on position to ba-
sic/standstill position in that case the automatic electronic control stops the gas supply by closing of magnetic valves and controls the
appliance in error mode moreover the red control lamp located on front side of device is lighting.
In case the fl ame detector of automatic burner control does not sense fl ame formation during ignition in that case stops the gas supply
and controls the appliance in error mode moreover the red control lamp is lighting.
In case during burning process the pressure diff erence decreases under the permissible minimal value on the air pressure switch than
the automatic control prohibits the operation as follows:
• stops the gas supply
• stops the operation of exhaust fan
• controls the appliance in error mode and red control lamp is lighting
ATTENTION! The restart of appliance, which is in safety status can only be possible by
pushing of „RESET” push button located on the PCB (inside of appliance) or on the tem-
perature regulator!
General information: The fl ame detector is self-checking and can just operate with the burner, other environmental eff ects (ambient
temperature,lights) can not infl uence it.

sure. Turn back the knob until red LED fl ashes. Check out the output voltage S1 and L1 between 110V and 115 V. Set the solenoid
valve at minimum pressure. After that set the room temperature value.
ATTENTION! The GTV-E warm air blowers can be operated by AHP-3 and AHP-MOD-type
temperature regulator, which may be purchased at appliance manufacturer . In case of
using different temperature regulator, please contact with the manufacturer in interest
of proper installation!
The control of appliance is performed by temperature regulator(room thermostat). It can be manually operated or equipped with prog-
ramme-clock according to the request.
AHP-3:
The appliance is controlled by a HEATING/0/COOLING selector and RESET button. It has a time switch. Use the two rotatable knob to
set the temperature. Thermostat can TURN ON and TURN OFF the appliance, it depends on the room temperature. You have a chance
daily and weekly programming with time switch.
Thermostat and appliance: Appliance is under voltage with selector. In this case the green lamp is lighting and you can chose from he-
ating or cooling mode.
Operation:
In heating mode, use the knob to set the maximal pressure (2 red lamp is lighting) and after turn the button back (50 % LED is lighting)
to set the minimal pressure. Next step to set required temperature with the knob.

The GTV-E-type warm air blowers apart from the checking of suspension and cleaning of cover, lamellas and circulating fan do not
need extra maintenances but to be able to preserve the long lifetime of appliance it is recommended to have yearly supervision done
with a qualifi ed service or expert.
Maintenance supervisions by the customer: (recommended half a yearly)
• supervision of circulating fan, if needed clean it (by high pressure air),
• supervision of outblowing apertures (lamellas)
• supervision of suspension points/surfaces by survey
WARNING! Before every maintenance the appliance must be detached from the electrical supply
by switching off the main-switch and disconnecting the connection plug located on the back side
of appliance!
ATTENTION! In case operational circumstances of appliance (atmosphere is contaminated with cor-
rosive substances,dirt) need it, then supervision and cleaning may have done more often! The main
reason of this that dirt placed on the fan may damage efficiency of appliance!

ATTENTION! The joint of pipes must be sealed and fixed! Not allowed longer flue system as the above
chart shows!
• See the following:
• the pressure drop of 1m inox Ø100mm pipe is 2Pa
• elbow 90° is equal about 1m-length pipe (2-3Pa)
Supplement: The fresh air supply and venting set can contain an elbow 90°. In case of use more elbows, you need to reduce the length
of fresh air supply and venting set, as follow:
It is allowed to use longer fresh air supply and venting set with isolation and condensate outlet. In
this case, contact the manufacturer!
