INSTALLATION

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, proceed

with the installation operations.

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 stand-

ards and regulations of the laws in force.

Handling (C)

Warning: The handling operations for the

burner can be highly dangerous if not carried

out with the greatest attention: keep any unau-

thorised people at a distance; check the integrity

and suitableness of the available means of han-

dling.

Check also that the area in which you are work-

ing 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).

During the handling, keep the load at not more

than 20-25 cm from the ground.

Caution: After positioning the burner near the

installation point, correctly dispose of all residual

packaging, separating the various types of

material.

Before proceeding with the installation opera-

tions, carefully clean all around the area where

the burner will be installed.

PRELIMINARY CHECKS

Checking the consignment

Caution: After removing all the packaging,

check the integrity of the contents. In the event

of doubt, do not use the burner; contact the sup-

plier.

The packaging elements (wooden cage or

cardboard box, nails, clips, plastic bags,

etc.) must not be abandoned as they are

potential sources of danger and pollution;

they should be collected and disposed of in

the appropriate places.

Checking the characteristics of the burner

Check the identification labels of the burner (A)

and the head (B), showing:

• the model (A);

• the year of manufacture, in cryptographic

form (B);

• the serial number (C);

• the data for electrical supply and the protec-

tion level (D);

• the electrical input power (E);

• the combustion head output (F).

Warning: A label that has been tampered with,

removed or is missing, along with anything else

that prevents the definite identification of the

parts and makes any installation or maintenance

work difficult.

The packaging of the burner

includes a wooden platform, so it is

possible to move the burner (still

packaged) with a transpallet truck or

fork lift truck.

During lifting, check that the burner

remains balanced and in a horizontal

position.

The manufacturer accepts no

responsibility in the event that lifting

is performed in a manner different to

that described in this manual.
