1. General Information

The burner may only be used for its intended purpose in accordance with the

product’s technical data.

We reserve the right to make design changes and cannot be held liable for any

misprints or typographical errors.

Modifying the design or using accessories or components that have not been

approved by Enertech in writing is strictly prohibited.

This Installation and Maintenance manual:

• is to be regarded as part of the burner and must always be kept near

the installation site.

• must be read prior to installation.

• is intended for use by authorised personnel.

1.1 Delivery inspection

• Make sure everything is delivered and the goods have not been

damaged during transit. Transport damage should be reported to the

shipping company.

• If something is wrong with a delivery, report it to the supplier.

1.2 Safety

- before installation:

• Installation and work on the burner and associated system

components may only be carried out by persons who have undergone

relevant training.

• The product is packaged to prevent damage from occurring when

handled – Handle the product with care! Lifting equipment must be

used to lift larger packages.

• The products must be transported/stored on a level surface in a dry

environment, max. 80% relative humidity, no condensation.

Temperature -20 to +60 °C.

- installation:

• The burner must be installed in accordance with local regulations for

re safety, electrical safety, and fuel distribution.

• The premises must comply with local regulations pertaining to use of

the burner and must have adequate air supply.

• The installation site must be free of chemicals.

• Fire extinguisher with Class BE recommended.

• Make sure when installing the burner that there is enough space to

service the burner.

• The electrical installation must be professionally carried out in

accordance with current mains electricity regulations and in a

professional manner.

• Make sure that the burner is suitable for the application (see Technical

Data).

• All components must be installed without being bent, twisted or

subjected to mechanical or thermal forces that affect components.

5 Bentone

• Care must be taken by the installer to ensure that no electrical cables

or fuel lines are pinched or otherwise damaged during installation or

service.

• Sharp edges can occur on, for example: ame tube, fan wheel and air

damper.

• The gas outlet from the pressure regulator must be congured in

accordance with applicable regulations and lead to a safe area.

- before rst start:

• The burner must not be put into operation without proper safety and

protection devices.

• Permitted ambient temperature during operation -10 to +60 °C. Max.

80% relative humidity, no condensation.

• The surface temperature of the burner’s components may exceed

60 °C.

• Handle with caution – the burner has moving parts, and there is risk

of crushing injuries.

• Seal inspections must be performed during installation and servicing

to prevent leakage.

• Fitting and installation work has been completed and approved.

• Electrical installation has been correctly performed.

• Flue gas ducts and combustion air ducts are not blocked.

• All actuators and control and safety devices are in working order and

correctly set.

• If the boiler is equipped with an access hatch, this must be equipped

with a hatch opening switch connected to the burner’s safety system.

• When in operation, the burner’s noise level can exceed 85 dBA – use

hearing protection!

- operation:

• Carry out all stipulated settings, service and inspection work within

the set time.

1.3 What to do if you smell gas

• Turn off the fuel supply.

• Turn off the device and remove the boiler from operation.

• Open windows and doors.

• Prevent open ames or sparking, e.g. do not turn lights on or off, do

not use any electrical appliances or mobile phones.

• Evacuate the building.

• Notify the installer or gas supplier of the problem so that it can be

rectied.

Measurements according to EN 15036-1:2006

Alt.1 The noise level of the burner can be

reduced by equipping the burner with

silencer. Installation must be done so

it does not prevent air supply to the

burner.

Alt.2 The burner’s noise level can be reduced

by connecting the burner’s air intake

to the air duct that opens into an

appropriate location. Installation must

be done so it does not prevent air supply

to the burner.

3.3 Function

1. Operating switch ON-Thermostat ON-Gas pressure switch ON-Air

damper closed.

Check that the air pressure switch does not indicate fan pressure,

then the motor starts.

2. Damper motor opens.

The damper motor opens the damper to the maximum load position.

Check that the air pressure switch indicates sucient fan pressure.

3. Damper motor closes.

The damper motor closes to the minimum load position, then the

ignition spark is produced.

4. Main and safety valves open.

The gas ignites and the ionisation electrode indicates ame.

5. The safety time ends.

Ignition spark and safety time cease. If the spark is missing or it

disappears after this time limit, the gas burner control is blocked.

6. Operating position.

The burner is in operating mode and can now switch to the capacity

controlled by the controller.

7. Stop.

The burner operation can be stopped with the operating switch or the

thermostat.

If the gas burner control is blocked

The red light in the gas burner control comes on. The burner is restarted by

pressing the reset button.

The program is canceled in the event of a power failure.

HThe program controller will only function if

- the program controller function has been configured ( Fnct = 1 ...4)

- the program setpoints (SPP1 ... SPP8) and

segment times (tP 1 ... tP 8) have been entered

Normal display Program is running

(the symbol for ramp appears)

Program pause

hAlter the present

setpoint with I and D

The controller controls to

the present setpoint.

(The value is accepted

automatically after 2 sec.)

When the program is

paused, the lower display

blinks.

8.6.6 Operator level „OPr“

8.7 Parameter level „PArA“

Two parameter sets, PAr1 und PAr2, can be stored.

Process data ProC

User data USEr (through the setup program only)

Any parameter (up to eight) can be displayed and edited here by using the setup

program.

Program data Pro (only with program controller/generator)

A program with up to eight segments is defined here, via the segment setpoints

SPP1 ... SPP8 and segment times tP 1 ... tP 8.

Proportional band 1a

a. with Pb1/2=0, the controller structure is not effective; depending on the display configuration,

these values are shown with the corresponding decimal places

Pb 1 0 ... 9999 °C/°F 0 °C/°F

Proportional band 2b

b. for controller output 2 (with 3-state controllers)

Pb 2 0 ... 9999 °C/°F 0 °C/°F

Derivative timec

c. with dt=0, the controller has no differential action (e. g. PI controller)

dt 0 ... 9999 s 80 s

Reset timed

d. with rt=0, the controller has no integral action (e. g. PD controller)

rt 0 ... 9999 s 350 s
