Riello FAMILY CONDENS 2.5 KIS E Utilisation Et Installation page 10

FAMILY CONDENS KIS E
The boilers are factory set to:
2.5 KIS E: 5.600 rpm in DHW mode and 4.500 in heating mode, and
the maximum length that can be reached is 2,9m for the ø 50 pipe
and 12,4m for the ø 60 pipe.
3.0 KIS E: 5.700 rpm in DHW mode and 5.100 in heating mode, and
the maximum length that can be reached is 1,4m for the ø 50 10 pipe
and 10,0m for the ø 60 pipe.
3.5 KIS E: 6.000 rpm in DHW mode and 5.300 in heating mode, and
the maximum length that can be reached is 0,9m for the ø 50 pipe
and 12,0m for the ø 60 pipe.
Should it be necessary to achieve greater lengths, compensate the
pressure drop with an increase in the r.p.m.of the fan, as shown in the
adjustments table, to ensure the rated heat input.
The minimum calibration is not modified.

The Ø 50 and Ø 60 configurations use test data obtained in the
laboratory.
In the event of installations that differ from the indications in the
"standard configurations" and "adjustments" tables, refer to the
equivalent linear lengths below (fig. 27).
In any case, the maximum lengths declared in the booklet are
guaranteed, and it is essential not to exceed them.

3.12 System loading and emptying (fig.28)
Once the hydraulic connections have been carried out, fill the system.
LOADING
- Open the caps of the lower automatic air vent valves (A) and upper
(E) by two or three turns; to allow a continuous venting of the air,
leave the plugs of valves A and E.
- Make sure the cold water inlet tap is open, turning it anti-clockwise.
- Open the filling tap (B) until the pressure indicated by the water
pressure gauge is between 1 and 1.5 bar.
- Close the filling tap (B).
NOTE: the venting of the FAMILY CONDENS KIS E boiler takes
place automatically via the two automatic bleed valves A and E, the
first positioned on the circulator and the second inside the air distri-
bution box.
EMPTYING
- Before starting emptying, switch off the electrical supply by turning
off the system's main switch
- Close the cold water inlet tap
a) Heating system:
- Close the shut-off devices of the heating system
- Manually loosen the system drain valve (C)
- The water is discharged through the discharge manifold (D) - for
details refer to paragraph "Discharge manifold"
b) Domestic hot water system:
- Open the hot and cold water taps of the device.
The discharge manifold (D) must be connected via a pipe (pro-
vided) to an appropriate collection and evacuation system in
the white water discharge drain in compliance with current reg-
ulations. The manufacturer is not liable for any damage result-
ing from the failure to channel the condensate.
3.13 Installation of collective positive pressure smoke pipes
The collective smoke pipe is a flue gases system suitable for col-
lecting and expelling combustion products of several appliances in-
stalled on different floors of a building (fig. 29).
The collective flues in positive pressure can be used only for type C
condensing appliances. Consequently the B53P/B23P configuration
is not permitted.
Installation of the boiler on collective flues in pressure is permitted
using a specific check valve, supplied as an accessory. See the re-
lated instructions for the assembly procedure.
The boiler is sized to operate correctly up to a maximum internal
pressure of the smoke pipe no higher than the value shown in the
multigas table (fig. 30).
Complete the check valve assembly operations and proceed with ad-
justment of the number of fan rotations as shown in the multigas ta-
ble. Make sure that the air suction and combustion fumes discharge
pipes are sealed.
The installation of the check valve requires the application of the
CAUTION label, supplied with the accessory, on a visible part of the
boiler casing. The application of the label is essential for safety pur-
poses during the maintenance or replacement of the boiler and/or
collective smoke pipes.
WARNINGS
The manufacturer assumes no liability if the check valve and
related label is not installed before the commissioning of the
boiler.
Appliances connected to a collective smoke pipe must all be of
the same type and have equivalent combustion characteristics.
The number of appliances that can be connected to a collective
positive pressure smoke pipe is defined by the designer of the
smoke stack.
MAINTENANCE FOR APPLICATION IN A COLLECTIVE PRES-
SURIZED SMOKE PIPE
During scheduled maintenance on the appliance you must also
check the condition of the check valve in order to guarantee correct
operation and safety of the system.
Before proceeding with maintenance you must conduct an analysis
of the combustion product and check the boiler operating status.
