5.3 Installation room

PreX H 3 cond boilers must be installed in dedicated rooms, meeting the current Technical Standards and Legislation and equipped with
adequate ventilation openings. The ventilation openings must be permanent, communicating directly with the outside and located at the
top and bottom in accordance with current regulations. The location of the ventilation openings and the fuel supply, electricity and lighting
circuits must comply with the regulations in force according to the type of fuel used. To facilitate cleaning the smoke circuit, at the front of the
boiler there must be a free space of at least the length of the boiler body and, in any case, never less than 1300 mm; it is also necessary to
check that, with the door open 90°, the distance between the door and the adjacent wall (Fig. 8) is at least equal to the length of the burner.
The boiler support surface must be perfectly horizontal. It is advisable to provide a flat cement plinth able to take the total weight of the boiler
plus the water. For the plinth dimensions, see the dimensions P x d (see table on page 58). If the burner is fed with fuel gas of specific
weight greater than that of the air, the electrical parts must be placed more than 500 mm above the floor. The appliance cannot be installed
outdoors because it is not designed to operate outside and does not have automatic anti-freeze systems.
