• 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.

-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

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.
