1. Safety Information

This Installation and Maintenance manual:

• is to be regarded as part of the burner and must always be kept near

the installation site.

• is intended for use by authorised personnel.

• must be read prior to installation.

• must be observed by all who work with the burner and associated

system components.

• work with the burner may only be carried out by certiﬁed installers/

personnel.

• Enertech AB is not liable for any typographical errors and reserves the

right to make design changes without prior notice.

• The burner may only be used for its intended purpose in accordance

with the product’s technical data.

• The burner may only be installed and operated by authorised

personnel.

• The product is packaged to prevent damage from occurring during

handling. 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.

• Check that the burner is compatible with the boiler’s output range.

• The label information on the rating plate refers to the burner’s minimum

and maximum power.

• The power data on the type sign refers to the burner’s min. and max.

power.

• 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.

• Make sure when installing the equipment that there is enough space to

service the burner.

• Permitted ambient temperature during operation -0 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.

• The installation site must be free of chemicals.

• Burner pipes, fan wheels and air dampers may contain sharp edges.

• The surface temperature of the burner’s components can exceed

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.

• Leak checks must be performed during installation and servicing to

prevent fuel 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 the design 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.

• After commissioning, if a steady red light on the burner control is

displayed, contact your installation technician.

2.5 Setting of brake disc and air ﬂow

Once the different output modes have been selected prior to commissioning,

basic settings for the burner can be made as shown in the air damper and

brake disc diagrams. See under Default settings. Note that it is simply a

matter of a default setting that should be adjusted retrospectively once the

burner has started. You should then conduct a ﬂue gas analysis and soot

quantity measurement.

2.6 Burner installation

2.6.1 Hole pattern

Make sure the hole pattern on the boiler is designed for burner ﬂange.

Combustion device d1d2d3

d1* If the burner tube is installed from inside the boiler.

d3* The hole pattern can be moved down if the burner tube is installed from

the front and the tabs in the ﬂange are removed.

2.7 Recommended nozzle and

pressure

Because of the various boiler types with varying furnace geometries and

furnace loads, it is impossible to commit to a certain scattering angle or a

speciﬁc distribution pattern.

It should be noted that the scattering angle and distribution pattern changes

with pump pressure.

Nozzle: 45° Solid/semisolid

60° Solid/semisolid

80° Solid/semisolid

Pump pressure: 14 bar (12-16 bar) depending on pump model
