BOILER ROOM
The MEGA boilers should be installed in rooms exclusively used for this purpose, in accordance with the technical standards and
legislation in force and featuring adequately sized ventilation openings. The ventilation openings must be permanent, directly
communicating with the outside and located in both a high and low position, in compliance with the standards in force.
The location of the ventilation openings, the fuel supply, power and lighting circuits must comply with the legislation in force in
relation to the type of fuel used.To assist the cleaning of the flue gas circuit, free space must be left at the front of the boiler no less
than the length of the boiler body and, in any case, never less than 1300 mm, checking that with the door open at 90° the distan-
ce between the door and the 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 should be used that is able to support the overall weight of the boiler plus the water content.
For the dimensions of the base, see the distances R x Q (table of dimensions).
WARNINGS
• If the burner is supplied with gas fuel whose specific weight is higher than air, the electrical parts must be located more than
500 mm from the floor.
• Check that the index of protection of the boiler is suitable for the characteristics of the room where the appliance is installed.
• Provide enough clearance to access the safety and control devices and to carry out the servicing operations.
• If the burner is supplied with gas fuel whose specific weight is higher than air, the electrical parts must be located more than
500 mm from the floor. The appliance cannot be installed outdoors as it is not designed to operate outside and does not featu-
re automatic frost protection systems.
INSTALLATION IN OLD SYSTEMS OR SYSTEMS TO BE UPGRADED
When the boiler is installed in old systems or systems to be upgraded, check that:
- The flue stack is suitable for the temperature of the products of combustion, calculated and manufactured according to the stan-
dards in force, airtight, insulated and not blocked or choked.
- The electrical system has been installed in compliance with the relevant standards by qualified personnel.
- The fuel supply line and any tanks are made according to the relevant standards.
- The expansion vessel/vessels can completely absorb the expansion of the fluid contained in the system.
- The flow-rate, discharge head and the direction of the flow of the circulating pumps are suitable.
- The system is washed, cleaned of slime, fouling, vented and watertight.
- A treatment system is available for special supply/top-up water requirements (see the reference values).
