Condensate Drain Connection - Ferroli ECONCEPT 51 A Instrucciones De Uso

Connection with coaxial pipes
fig. 25 - Examples of connection with coaxial pipes (
For coaxial connection, fit the unit with one of the following starting accessories. For the
wall hole dimensions, refer to fig. 33. Any horizontal sections of the fume exhaust must
be kept sloping slightly towards the boiler, to prevent possible condensate from flowing
back towards the outside and causing dripping.

Before carrying out installation, check with table 2 that the maximum permissible length
is not exceeded, taking into account that every coaxial bend gives rise to the reduction
indicated in the table. For example, a Ø 80/125 duct comprising a 90° bend + 1 horizontal
metre has a total equivalent length of 1.5 metres.

Separate Ø80 ducts can be connected directly to the unit.
Before proceeding with installation make sure the maximum permissible length has not
been exceeded, by means of a simple calculation:
1. Completely establish the layout of the system of split flues, including accessories
and outlet terminals.
2. Consult the table 4 and identify the losses in m
ponent, according to the installation position.
3. Check that the sum total of losses is less than or equal to the maximum permissible
length in table 3.

3.6 Condensate drain connection

The boiler is equipped with an internal trap C for condensate draining.
Fit the inspection union A on the trap, also fitting seal B. Press the flexible tube D on
about 3 cm and secure it with a clamp.
Fill the trap with approx. 0.5 l. of water and connect the flexible tube to the drainage sys-
tem.
1. Fit the inspection union A on the trap, also fitting seal B. Press the flexible tube D
on about 3 cm and secure it with a clamp.
2. Fill the trap with approx. 0.5 l. of water.
3. Connect the flexible tube to the drainage system.

4. SERVICE AND MAINTENANCE
All adjustment, conversion, startup and maintenance operations described below must
only be carried out by Qualified Personnel (meeting the professional technical require-
ments prescribed by current regulations) such as those of the Local After-Sales Techni-
cal 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. Loosen the gas valve fixing ring "A".
2. Remove the seal "E" and replace gas nozzle "D" with the one contained in the con-
version kit.
3. Refit the parts and check the tightness.
4. Modify the parameter on the control system.
• 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 operation) or 01 (for LPG operation).
• press the DHW buttons (details 1 and 2 - fig. 1) for 10 seconds.
• the boiler will return to standby mode
5. Apply the label, contained in the conversion kit, near the dataplate.
6. Using a combustion analyser connected to the boiler fume outlet, make sure the
CO content in the fumes, with the boiler operating at max. and min. output, com-
