General
• The electrical installation must be professionally carried out in
accordance with applicable high voltage regulations, as per Enertech’s
recommendations.
• Before servicing, shut off the fuel supply and turn off the power to the
burner.
• Seal inspections must be performed during installation and servicing to
prevent gas leakage.
• Care should be taken by the installer to ensure that no electrical cables
or fuel lines are crushed or otherwise damaged during installation or
servicing.
• 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.
• The burner must not be put into operation without proper safety and
protection devices.
• A Class BE fire extinguisher is recommended.
• It is forbidden to alter thedesign or use accessories which have not
been approved by Enertech in writing.
• Prior to operation, the following points must be checked:
-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
Actions to take if you smell gas
Turn off the equipment and the boiler. Open windows and doors. Prevent
open flames or sparking, e.g. do not turn lights on or off, do not use any
electrical appliances, do not use mobile phones. Open windows and doors.
Close the gas ball valve. Warn residents; do not use doorbells. Evacuate
the building. Notify the installer or gas supplier once the building has been
evacuated.

Measurements according to EN 3746: 2010
Alt.1 The sound 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. General instruktions
3.1 General instructions
The installation of the gas burner must be carried out in accordance with
current regulations and standards. The installers of gas burners should
therefore be acquainted with all regulations and ensure that the installation
complies with the requirements. The installation, mounting and adjustment
should be made with the greatest care and only the correct gas should be
used.
3.2 Operating instructions
The operating instructions accompanying the burner should be left in a
prominent position in the boiler room.
3.3 Instructions
The user should be thoroughly in-structed in the function of the gas burner
and the whole installation. The supplier must instruct the user.
3.4 Inspection and maintenance
Daily inspection is advisable..
3.5 Start up
After the burner has been fitted to the boiler and the electric connection, the
leakage control, the venting and the electric function test have been carried
out, the burner will be ready for start-up.
Howerer, study the sections dealing with adjustments of multi-bloc,
combustion air and combustion head. Open the ball valve and switch on the
main switch. If the burner starts the actual adjustment can be made.
3.6 Commissioning of installation
Control of the combustion. The combustion quality is checked by means of a
flue gas analysis device. Adjust the burner to appr. 20%
excess air in accordance with the table. Check the flue gas temperature.
Calculate the efficiency. Check also the actual gas volume on the gas meter
so that the correct input is achieved.
