Instructions for the installer
x = not less than the length of the boiler body
(dimensions in mm); in any case, never less than 1300 mm.
xx = see instructions to the side.
3.4 - HEATING PLANT LOCATION
The boiler must be installed in accordance with the rules and
regulations in force.
The room must be well ventilated with openings having an
area of not less than 1 / 30 of the floor area of the boiler room
with a minimum of 0.5 m².
The ventilation openings must be permanent, communicating
directly with the outside and be positioned at a level high and
low in accordance with the regulations in force.
The location of the vents, the supply circuits Fuel, power
distribution and lighting must comply with the applicable laws
in force in relation to the type of fuel used
You should install the boiler as close as possible to connection
of the chimney.
To facilitate the cleaning of the smoke circuit in front of the
boiler, it must have a clear space not less than the length the
boiler , and in any case, never less than 1300mm and it must
verify that with the door open to 90 ° the distance between
the door and the adjacent wall, is at least equal to the length
burner.
The boiler may be placed directly on the floor, because it has
a basement.
However, it is useful to provide a concrete platform, a plan to
level and able to withstand the weight of the boiler when is
filled with water.
When placed on the hoof, this must be have at least a size of
Q x S (see size tables).
Once installed, the base must be perfectly horizontal and well
stable (to reduce vibration and the noise level).

3.3 - HANDLING
The boiler can be easily handled by lifting hooks
through holes or higher.
If for reasons of space was necessary, is
possible to remove the door to facilitate the
introduction in the central heating.
3.5 - BURNER
The burners in the service of boiler INOXIA GJ will be CE
certified, and in particular comply with:
- Gas Appliance Directive (90/396/EEC);
- EMC Directive - Electromagnetic Compatibility (89/336 /
EEC).
They must also be approved in accordance with the
specifications:
- UNI EN 676 - forced draft burners for fuel gas.
- Efficiency Directive (92/42 EEC)
3.5.1 - CHOICE OF THE BURNER
A proper selection and the adjustment of the burner are
fundamental for an optimal operation of the boiler and
therefore they should be accurate and not underestimated.
The burner must be chose verifying its field work (fuel flow
rate - pressure in the combustion chamber) that should
compatible with similar characteristics declared the boiler
Please note that the pressure drop gas side of the boiler, or
the back pressure in the combustion chamber, are reported at
zero pressure at the base of the chimney.
It is appropriate that the burner tube length is not less than
the minimum stated in the table below, and the flame must
be developed and adapted to the characteristics of our
combustion chamber
To exploit all the surface of the heat exchange dead-end, you
must use burners that are able to provide a flame “long and
narrow” in every
operating condition, or even at minimum power in the case of
setting up two or more stages or modulating.
Flames too short causing localized overheating the front of
the furnace and combustion products, not sufficiently cooled,
take the flue to extreme heat can cause serious damage to
the generator.
