1. DESCRIPTION
1.1 Warning
• Read the manual before assembling or commissioning.
• The contents of this manual are to be observed by all who work for any
reasoN on the unit and its appertaining system parts.
• This manual is intended especially for authorised personnel.
• This manual is to be regarded as part of the burner and shall always be
available near the place of installation.
• The burner is only to be installed by qualified personnel
• Check that the burner is suitable for the boiler´s power range.
• The burner is to be installed such that it complies with any local
regulations relating to electrical safety, boilers and fuel distribution.
• Check that the burner is approved for the gas quality intended used.
• No burner safety systems are to be disengaged.
• The fitter is to ensure that the boiler room is supplied with fresh air
ventilation that is sufficient in accordance with local standards.
• Before servicing, shut off the fuel supply and the power supply to the
burner.
• The outer temperature of the boiler´s components can exceed 60 °C.
• Check that the guide stop is installed before servicing.
• Take great care when servicing. Trap and pinch risks can be present.
• The boiler´s sound level can exceed 85 dBA during operation. Use ear
protectors when present in the boiler room.
Safety directions
• The electrical installation shall be made according to valid regulations
for heavy current and in a professional way, so that the risk of leaking
gas, fire or personal injury is avoided.
• If another electrical connection is used than the one recommended by
Enertech, there might be a risk of material damage or personal injury.
• Notice should be carefully taken by the installer that no electrical cables
or gas pipes get squeezed or damaged when installing or at service
• If the boiler is provided with an opening door, this should be interlocked
with a door switch.
Acceptance inspection
• Ensure that everything is delivered and that there is no transport
damage.
• If there is anything wrong with the delivery, please report it to the
supplier.
Preparations for installation
• Ensure that the size and capacity range of the burner are suitable for
the boiler.
• Power data on the data plate refer to the minimum and maximum
power of the burner.

5. MOUNTING OF THE BURNER
!For maintenance of the brake plate, nozzles, electrodes etc, when using a long
design of the burner tube, you have to remove the nozzle assembly from the
connecting pipe and move the assembly backwards in the fan housing (from the
boiler).
Fit the burner to the boiler by means of 4 bolts M12. For flange and bolt
dimensions see technical data.
If for some reason you want to separate the burner from the gas flange with
burner head and valve package you can do so.
Do like this:
• Remove the cover of the fan housing.
• Loosen the nut D of the gas assembly package.
• Loosen the electric cables to the valve package.
• Loosen the screws B on both sides.
• Loosen the stop bolt C on the pull rods.
• Loosen the ignition cable and the ionisation cable from the gas
assembly.
• Pull out the burner on the pull rods and put it in a suitable place.
When the burner head and the gas flange have been fitted to the boiler it is
easy to lift up the burner to where it belongs.
5.1 Inspection of gas assembly
If the gas assembly needs to be inspected the pull rods are very useful.
Do like this:
• Remove the cover of the fan housing.
• Loosen the nut D of the gas assembly package.
• Loosen ignition cable and ionisation cable of gas assembly.
• Loosen the screw A on both sides.
• Pull out the burner on the pull rods.
• Loosen the screws B on the gas flange.
• Withdraw the gas assembly.
Ensure that the O-ring between the gas assembly and the gas flange will be
in the correct position when the gas assembly is fitted again

5.2 Adjustment of the position of the
shrouded disc in the blast tube
Sometimes it is necessary to adjust the position of the shrouded disc in the
blast tube. This can be done with the screw E (can be adjusted when the
burner is in operation). If you turn the screw to the left the shrouded disc will
move forward (+), to the right it will move backward.

6.5 Function LME22
1. Operating switch ON-Thermostat ON-Gas pressure switch ON-Air damper
closed.
A control is made that the air pressure switch does not indicate fan pressure. Then the
burner motor starts.
1. Air damper motor opens.
The air damper motor opens the damper to full load. A control is made that the air
pressure switch indicates sufficient fan pressure.
2. Air damper motor closes.
The air damper motor closes to low load . Then the ignition spark is formed.
3. Main and safety valves open
The gas is ignited. The ionization electrode indicates a flame.
4. The safety time expires.
The ignition spark goes out. The safety time expires. If there is no flame or if for some
reason the flame disappears after this time limit, the burner control locks out.
5. Operating position..
The burner is in operating position and can now change over to full load if the operating
switch and the thermostat for full load are in positon ON. The burner can alternate
between full and low load depending on set temperature.
6. Stop
The operation of the burner can now be interrupted by means of the operating switch
or the thermostat.
The control locks out.
The red lamp in the control is lit. Restart the burner by pressing the reset button.

The red alarm signal lamp lights continuously after the alarm is disconnected.
Diagnostics for alarm triggers can be read as specified by the following
sequence:
Limit on start attempts
LME 11 … limits the number of start attempts if the flame does not ignite
on start-up or goes out during operation. LME 11 … permits a maximum of
three start attempts if the start cycle is uninterrupted.
