5. INSTALLATION
5.1 Packaging
MEGAPREX N
boilers are supplied with the door, smokebox and insulation installed, and the panels in a separate cardboard box.
The instrument panel and ceramic fiber padding for the burner nozzle can be found inside the combustion chamber.
The instrument panel is supplied in a cardboard box located inside the combustion chamber.
5.2 Handling
MEGAPREX N
boilers are equipped with eyebolts for lifting. Handle the unit carefully, using suitable equipment for the weight to be lifted.
Before connecting the boiler, remove the wooden base.
5.3 Installation site (Fig. 4)
MEGAPREX N
boilers must be installed in rooms to be used exclusively for that purpose, in accordance with current technical standards
and legislation, and featuring adequately sized ventilation openings. The ventilation openings must be permanent, directly open to the outside,
and located in both high and low positions, in accordance with current standards. The location of the ventilation openings and fuel supply,
electrical power distribution and lighting circuits must comply with current legal provisions for the type of fuel used. To facilitate the cleaning of
the flue gas circuit, space must be left at the front of the boiler, greater than or equal to the length of the boiler body, and no less than 1,300 mm.
With the door open 90º, verify that the distance between the door and adjacent wall (
X
) is at least equal to the length of the burner.
The boiler support surface must be perfectly horizontal. A flat cement base is recommended, able to support the full weight of the boiler plus the
water content. For the base dimensions, see the
R x Q
distances (dimension table). If the burner is powered by a fuel gas with a specific weight
higher than air, the electrical parts must be located at least 500 mm from the floor. These boilers cannot be installed outdoors because they are
not designed to operate outside, and are not equipped with automatic frost protection systems.
INSTALLATION IN OLD SYSTEMS
If the boiler is to be installed in an old system, verify that:
- The chimney is suitable for the temperature of the combustion products, has been calculated and manufactured in accordance with current
standards, and is airtight, insulated, and not blocked or choked.
-
The electrical system has been installed by qualified personnel, in accordance with current standards.
- The fuel supply line and any tanks have been installed in accordance with current standards.
- The expansion vessel(s) can completely absorb the expansion of the fluid contained in the system.
- The flow-rate, static pressure, and direction of flow of the circulation pumps are suitable.
- The system is clean, free of slime and deposits, vented and watertight.
- A treatment system is available for supply/top-up water (see reference values).
