Temperature -20 to +60 °C.
• Check that the burner is compatible with the boiler’s output range.
• All components must be installed without being bent, twisted or
subjected to mechanical or thermal forces which can affect the
components.
• The burner must be installed so that it complies with local regulations
for fire safety, electrical safety, and fuel distribution.
• The gas outlet from the pressure regulator shall be configured in
accordance with applicable regulations and lead to a safe area.
• Make sure when installing the equipment that there is enough space to
service the burner.
• Permitted temperature during operation -10 to +60 °C. Max 80%
relative humidity, no condensation.
• The installer must ensure that the room has adequate air supply.
• The room must comply with local regulations pertaining to its intended
use.

1. General Information
6Bentone
5Bentone
• 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.
