1. General Information
The burner may only be used for its intended purpose in accordance with the
product’s technical data.
We reserve the right to make design changes and cannot be held liable for any
misprints or typographical errors.
Modifying the design or using accessories or components that have not been
approved by Enertech in writing is strictly prohibited.
This Installation and Maintenance manual:
• is to be regarded as part of the burner and must always be kept near
the installation site.
• must be read prior to installation.
• is intended for use by authorised personnel.
1.1 Delivery inspection

• Installation and work on the burner and associated system
components may only be carried out by persons who have undergone
relevant training.
• The product is packaged to prevent damage from occurring when
handled – Handle the product with care! Lifting equipment must be
used to lift larger packages.
• The products must be transported/stored on a level surface in a dry
environment, max. 80% relative humidity, no condensation.
Temperature -20 to +60 °C.
- installation:
• The burner must be installed in accordance with local regulations for
re safety, electrical safety, and fuel distribution.
• The premises must comply with local regulations pertaining to use of
the burner and must have adequate air supply.
• The installation site must be free of chemicals.
• Fire extinguisher with Class BE recommended.
• Make sure when installing the burner that there is enough space to
service the burner.
• The electrical installation must be professionally carried out in
accordance with current mains electricity regulations and in a
professional manner.
• Make sure that the burner is suitable for the application (see Technical
Data).
• All components must be installed without being bent, twisted or
subjected to mechanical or thermal forces that affect components.
5Bentone
• Care must be taken by the installer to ensure that no electrical cables
or fuel lines are pinched or otherwise damaged during installation or
service.
• Sharp edges can occur on, for example: ame tube, fan wheel and air
damper.
• The gas outlet from the pressure regulator must be con gured in
accordance with applicable regulations and lead to a safe area.
- before rst start:
• The burner must not be put into operation without proper safety and
protection devices.
• Permitted ambient temperature during operation -10 to +60 °C. Max.
80% relative humidity, no condensation.
• The surface temperature of the burner’s components may exceed
60 °C.
• Handle with caution – the burner has moving parts, and there is risk
of crushing injuries.
• Seal inspections must be performed during installation and servicing
to prevent leakage.
• 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.
• 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!
- Operation:
• Carry out all stipulated settings, service and inspection work within
the set time.
1.3 What to do if you smell gas
• Turn off the fuel supply.
• Turn off the device and remove the boiler from operation.
• Open windows and doors.
• Prevent open ames or sparking, e.g. do not turn lights on or off, do
not use any electrical appliances or mobile phones.
• Evacuate the building.
• Notify the installer or gas supplier of the problem so that it can be
recti ed.

Measurements according to EN 15036-1:2006
Alt.1 The noise 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.
