General Notes - Desa BG Serie Manual De Instrucciones

This Instruction Manual is an integral part of the device and as such must always be kept with the device. This is also
the case when the heater is sold to another user. The Manual must therefore be conserved and consulted carefully
before any action. In the case of damage or loss, you can at any time ask the local After Sales Service for a copy of the
Manual.
After removing the packaging, first make sure that the contents are complete and undamaged. If the heater does not
match with the Manual in any way, contact the Agency that sold the heater.
Installation of the BG series WARM AIR HEATER must be carried out by qualified companies under Law 5 March 1990
n°46. On completion of the job, they provide the owner with a declaration of conformity of the correctly carried out
installation, that is according to the current applicable Norms requires and according to the indications provided by the
Manufacturer in this Instruction Manual.
The heaters have been manufactured for room heating and they must be used for this purpose, compatibly with their
performance characteristics. The Manufacturer accepts no contractual or extracontractual responsibility for damage
caused to people, animals or property, due to errors in installation, adjustment and maintenance or to improper use.
Excessive temperature represents a risk for health and a waste of energy. Avoid leaving rooms closed for long periods of
time. Open the windows periodically to ensure an adequate air change.
During the first start-up, there may be smells and smoke due to evaporation of the liquid used to protect the heat
exchanger during storage; this is a normal phenomenon that will disappear after a brief operation time. The rooms must
be adequately aerated.
On leaving the heater unused for a long period, you should carry out at least the following operations:
• Turn off the main heater switch and the main plant switch.
• Close the main fuel supply valve.
If the heater is not used for a long period of time, we suggest you contact the After Sales Service or other professionally
qualified personnel for restarting.
All heaters must be fitted exclusively with original accessories. The Manufacturer is not responsible for any damage
caused by improper use of the heater and by the use of accessories that are not original.
All references to Law, standards, directives and technical rules in this manual are to be considered as informative only
and valid at the date of printing of the Manual. The enforcing of new dispositions or the alteration of current ones do not
create any Manufacturer obligations towards third parties.
Repairs and maintenance must be carried out by the After Sales Service or by qualified personnel as specified in this
Manual. Do not alter or tamper with the heater: this can create dangerous situations and the Manufacturer will not be
responsible for any damage.
The systems that must be installed (oil pipes, electrical supplies, etc.) have to be suitably fastened and must not
represent any obstacle that could cause tripping.
The Manufacturer is responsible for conformity of his product to laws, directives and instructions standards current at
the date of sale. Knowledge and observation of legislative instruments and of standards for the design of systems, and
for installation, operation and maintenance are the exclusive responsibility of respectively the designer, the installation
personnel and the user.
The Manufacturer is not responsible for failure to observe the instructions in this Manual, for the consequences of any
operation carried out that is not specifically foreseen, or for any translations causing erroneous interpretations.
The heater is designed for operation at the thermal power and the airflow rate as specified in the Technical Data
Chapter. A thermal power that is too low and/or an airflow that is too high can lead to condensation in the flue, with
consequent irreparable corrosion to the heat exchanger. A thermal power that is too high and/or an airflow that is too
low cause abnormal overheating of the heat exchanger with consequent actuation of the safety systems and damage to
the heat exchanger.
