GENERAL INSTRUCTIONS for INSTALLER,
USER and MAINTENANCE PERSONNEL
Thank you for your preference and trust granted! SIABS is pleased to have You among
his Customers; our appliances are designed and manufactured to the most modern and
rational processing systems and we do think that their use will be fully satisfactory.
To keep appliances perfectly working and safe, time passing, we invite you to read and
follow the instructions of this handbook and commit all installation and maintenance
(ordinary and extraordinary) operations only to skilled personnel, with specific
technical skills in the field of components of heating, preferably t o SIABS authorized Service
Centre.
For the INSTALLER:
- read carefully the warnings in the manual before performing any operation
as they provide important information concerning th e safety of installation, use and
the necessary maintenance operations to be performed
- this manual is integral and essential part of the product and must be delivered to
the user; retain it carefully for further consultations
- in case of non-compliance with the following instructions, the warranty
covering the product(s) will be null and void
- BEFORE THE INSTALLATION, verify that local gas distribution (type of gas and
pressure) and appliance settings are compatible
- appliance must be installed only in premises with adequate ventilation
- installation should be done in accordance with the Regulations in force in the
country of destination, to the state of art, following instructions by the Manufacturer
- incorrect installation can cause damage to people, animals and things; the
Manufacturer doesn’t accept any contractual and extra-contractual liability in tort

FOR YOUR SAFETY
IMPORTANT: appliances MUST NOT be used in domestic environments. This appliance
will be devoted only to the use for which it was expressly provided, all other uses will be
considered improper and therefore dangerous.
IMPORTANT: appliances MUST NOT be used in ambient with flammable materials,
liquids or vapours: non-compliance with these requirements may be cause of death, injury
to persons or damage to things.
Warranty
SIABS guarantees its products, whether installed by authorized personnel, for a period of 24
months from the invoice date. The warranty does not cover the components supplied by third
parties, these are subject to the conditions of the original warranty.
The guarantee is only the free supply on Ex-Works basis, of parts with manufacturing or
workmanship defects.
The guarantee does not cover problems due to carelessness, incorrect setting, misuse of the
appliance or fortuitous accidents, and not dependent on imperfection processing or defective
materials, and those due to dismantling or changes without prior authorization from SIABS.
The correct functioning of the appliances depends on a proper installation and start-up. Failure
to comply with these rules immediately involves the decay of the guarantee, and therefore of
responsibility by the manufacturer.
In case of gas smell: DO NOT operate the heating plant, vent the ambient,
DO NOT start apparatus or electric switches; contact the installer and gas
supply company and follow scrupulously their instruction

IMPORTANT: "GAS supply pressure", defined as the dynamic pressure of the circuit,
or part of the circuit downstream of the pressure reducer, with all the appliances running,
and must be detected in this condition. With lower pressure difficulties in start-up may
occur.

INSTALLATION
Ventilation of the ambient
The unit leaves the combustion products into the environment in which it is used (appliance
type A1). It is therefore necessary to ensure ventilation and air changes of the premises
in which the appliance is installed, realizing appropriate air outlet openings on the
perimeter walls of the same, or creating a system of mechanical ventilation. To ensure a
sufficient air change, the flow of air needed can be calculated using the following equation (UNI
EN 13410):
V
tot
= Qnb x L
V
tot
air change flow rate in m
3
/h
Q
nb
total h e ating power installed in the premises in kW
L air change coefficient (must be 10 m
3
/h / kW)
IMPORTANT: air change coefficient “L” to be used MUST NOT
be lower than 10 m
3
/h for each kW of installed power
For NO reason
the appliance(s) can be installed:
in rooms smaller than 12 m³
in ambient used as residential ambient
where wind speed is higher than 2 m/s
Appliances must be installed in wellventilated and manned ambient, in
compliance with current legislation
Manu_ENG_DC_DCeco_rev. 0_04_2012 page 8
Positioning
The appliances can be installed on walls / pillars, or hanging at ceiling. On request, we can
provide supports (S hooks and chains are excluded) for suspension at ceiling (picture 1), or
wall brackets to fix the heaters on the wall (picture 2) with different angled positions for
the heater. The following figures will show you how to install all types of appliances.
picture 1 – Installation with chains DC picture 2 – Installation at wall DC
picture 1 – Installation with chains DCeco picture 2 – Installation at wall DCeco
The brackets provided by SIABS allow an angle of installation variable once mounted on a wall
or pillar, in order to get a better heat distribution (picture 3, supports for DCeco version)
picture 3 – different angles : 5° , 15° , 30° , 45°
Manu_ENG_DC_DCeco_rev. 0_04_2012 page 9
IMPORTANT!
at each side of the burner 2 hooks are provided with M8 inserts, for fixing to a wall or
at ceiling by means of appropriate brackets (not supplied, available on request); do not
create other anchor points on the carpentry of the heater and in particular on
the body burner, but use only those designed by the factory
we recommend SIABS original brackets for installation of the radiant heaters
for fixing brackets on a wall or pillars assess the consistency of walls and the load
applied, in order to choose the correct anchors to be used; in any case provide
blocks with M8 screw minimum diameter (e.g. anchor Fischer TA - M in steel, with M8
screw)
IMPORTANT: appliances must be installed in horizontal position, contact us in case of
different inclination. In any case, the system of fixing / suspension must allow thermal
expansion of appliance (some millimetres depending on the model).
Handling
During extraction of the appliances from package and for all operations of handling till final
place of installation, gas valves / flame controls or flanges of the injection group must NOT be
used as lifting points, as in the pictures below.
Appliances must be taken at the installation point / height inside its package or using M8
inserts: all other parts of the appliances are NOT designed to withstand its weight.
