Page 5: General Information And Precautions
GENERAL INFORMATION AND PRECAUTIONS This machine is suitable for the following uses: a) Direct heating of the blown air through its own fan unit. The heat exchange occurs by contact between the external walls of the combustion chamber / heat exchanger and the air that passes through it. - Page 6 Information on safety and prevention The machine has been designed and built in compliance with the standards and directives in force, applying the known technical safety rules and providing for all potential dangerous situations. However, it is necessary to take into account that careless and clumsy use of the machine can cause situations of danger of death for the user or third parties, as well as damage to the machine itself or to other assets.
- Page 7 CONSTRUCTION EXAMINATION AND SAFETY REQUIREMENTS The warm air heater consists of an aluminium frame and an external panelling in pre-painted sheet metal: the panels are internally insulated with a glass wool mat. In the heating section we find a combustion chamber and a heat exchanger. In this area, the insulating mat is protected against the danger of overheating by a galvanized sheet cover.
- Page 8 Other essential safety requirements Electrical equipment. After the various assembly stages, all warm air heaters are subjected to the following electrical checks to verify compliance: visual check of the electrical circuit and tightening of the connections; continuity of the earth circuit; insulation resistance test;...

Perform a combustion analysis. 1) In the combustion analysis of the warm air heater, combined with a modulating burner, the combustion analysis must be done both at Qnom (nominal heat input), and at Qmin (minimum heat input). The combustion, efficiency and hygiene values obtained, including those of NOx, must be recorded at these two thermal flows. - Page 37 automatic stop the burner in case the average air outlet temperature overheat above the pre- set value imposed by the regulation. The set point at 100°C, is fixed by the manufacturer. This set point must not be changed to avoid the overheating of the warm air heater.

Close adduction of the fuel WARNING The warm air heater and the burner must be serviced by an authorised service centre or by qualified personnel, in compliance with the requirements set forth by law.
- Page 44 Check that the combustion chamber is not damaged. Check that the seal of the burner supporting plate and the relevant seal on the nozle are in good condition; if not, replace them with seals having the same code. When mounting back the burner (4) check the tightening of the bolts on the burner plate. Note: All seals are asbestos-free and compliant with EC standards.
