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.
