Installation

4.1

Notes on safety for the installation

After carefully cleaning all around the area where the burner will be
installed, and arranging the correct lighting of the environment, pro-
ceed with the installation operations.

4.2

Handling

The burner packaging includes a wooden platform, it is therefore
possible to move the burner (still packaged) with a transpallet truck
or fork lift truck.

4.3

Preliminary checks

Checking the consignment

Installation

DANGER

All the installation, maintenance and disassembly
operations must be carried out with the electricity
supply disconnected.

WARNING

The installation of the burner must be carried out by
qualified personnel, as indicated in this manual and
in compliance with the standards and regulations of
the laws in force.

DANGER

Combustion air inside the boiler must be free from
hazardous mixes (e.g.: chloride, fluoride, halogen);
if present, it is highly recommended to carry out
cleaning and maintenance more frequently.

WARNING

The handling operations for the burner can be high-
ly dangerous if not carried out with the greatest at-
tention: keep any unauthorised people at a
distance; check the integrity and suitableness of the
available means of handling.
Check also that the area in which you are working
is empty and that there is an adequate escape area
(i.e. a free, safe area to which you can quickly move
if the burner should fall).
When handling, keep the load at not more than 20-
25 cm from the ground.

After positioning the burner near the installation
point, correctly dispose of all residual packaging,
separating the various types of material.

CAUTION

Before proceeding with the installation operations,
carefully clean all around the area where the burner
will be installed.

CAUTION

After removing all the packaging, check the integrity
of the contents. In the event of doubt, do not use the
burner; contact the supplier.

The packaging elements (wooden cage or card-
board box, nails, clips, plastic bags, etc.) must not
be abandoned as they are potential sources of dan-
ger and pollution; they should be collected and dis-
posed of in the appropriate places.

WARNING

The output of the burner must be within the boiler's
firing rate.

WARNING

A burner label that has been tampered with, re-
moved or is missing, along with anything else that
prevents the definite identification of the burner
makes any installation or maintenance work diffi-
cult.
