fig. 25 - Examples of connection to flues (
To connect the ECONCEPT TOP MICRO C boiler to a multiple flue or a single chimney
with natural draught, the flue or chimney must be expressly designed by professionally
qualified technical personnel in conformity with the current regulations and be suitable
for sealed chamber units equipped with a fan.
In particular, chimneys and flues must have the following characteristics:
• Be sized according to the method of calculation given in the current regulations.
• Be fumetight, resistant to the fumes and heat and impermeable to condensate.
• Have a round or quadrangular section, with vertical progression and no constric-
tions.
• Have ducts that convey the hot fumes at a suitable distance or isolated from com-
bustible materials.
• Be connected to only one unit per floor.
• Be connected to a single type of unit (all or only forced draught units or all and only
natural draught units).
• Have no mechanical suction devices in the main ducts.
• Be at a lower pressure, along the entire length, in conditions of stationary operation.
• Have at their base a collection chamber for solid materials or condensate, provided
with an airtight metal door.

3.7 Condensate drain connection
The boiler is equipped with an internal trap to drain condensate. Fit the inspection union
A and hose B, pressing it in for approx. 3 cm and securing it with a clamp. Fill the trap
with approx. 0.5 l. of water and connect the hose to the drainage system.

4. SERVICE AND MAINTENANCE

All adjustment, conversion, commissioning and maintenance operations described be-
low must only be carried out by Qualified Personnel (meeting the professional technical
requirements prescribed by current regulations) such as those of the Local After-Sales
Technical Service.
FERROLI declines any liability for damage and/or injury caused by unqualified and un-
authorised persons tampering with the unit.
4.1 Adjustments
Gas conversion
The unit can operate on Natural Gas or LPG and is factory-set for use with one of these
two gases, as clearly shown on the packing and on the dataplate. Whenever a different
gas to that for which the unit is arranged has to be used, a conversion kit will be required,
proceeding as follows:
1. Remove the casing.
2. Open the sealed chamber.
3. Replace the nozzle A inserted in the mixer, with that contained in the conversion kit.
4. Reassemble and check the tightness of the connection.
5. Apply the label, contained in the conversion kit, near the dataplate.
6. Refit the sealed chamber and casing.
7. Modify the parameter for the type of gas:
• put the boiler in standby mode
• press the DHW buttons (details 1 and 2 - fig. 1) for 10 seconds. the display
shows "P01" flashing.
• press the DHW buttons (details 1 and 2 - fig. 1) to set parameter 00 (for natural
gas) or 01 (for LPG).
• press the DHW buttons (details 1 and 2 - fig. 1) for 10 seconds.
• the boiler will return to standby mode
8. Check the working pressure.
9. Using a combustion analyser connected to the boiler fume outlet, check that the
CO content in the fumes, with the boiler operating at max. and min. output, corre-
2
sponds to that given in the technical data table for the corresponding type of gas.
