First Commissioning - Riello Residence Condens KIS n Installateurhandbuch

With the operation completed, perform a thorough control of
all seals of the combustion product evacuation and air suction
pipes by performing a combustion analysis.
NOTE: If the fan is removed, make sure the check valve is put back
in the correct direction (see fig. 29).
4 - COMMISSIONING
4.1 First commissioning preparation
Before the ignition and the functional testing of the boiler it is neces-
sary to:
- Check that the system's fuel and water supply taps are open (fig. A).
fig. A
- Check that the gas type and the power supply pressure are those
for which the boiler is designed.
- Check that the deaerator cap is open.
- Check that the pressure of the water circuit when cold, displayed
on the water gauge, is between 1 bar and 1.5 bar and that the
circuit is de-aerated
- Check that the pre-loading of the expansion tank is adequate (see
"Technical data" table).
- Check that the electrical connections have been carried out cor-
rectly
- Check that the combustion product outlet and air suction pipes
were adequately realised
- Check that the circulator rotates freely because, especially after
long periods of non-operation, deposits and/or debris can prevent
free rotation.

- Insert a screwdriver in the hole (1) of the circulator
- Press (a) and turn the screwdriver (b) until the release of the crank-
shaft.
Perform this operation with extreme caution to avoid damaging
the components.

First commissioning

When the boiler is first started the siphon for collecting the con-
densate is empty.
It is therefore indispensable to create a head of water filling the
siphon before starting up, following these instructions:
- remove the siphon by releasing it from the plastic pipe con-
necting to the combustion chamber
- fill the siphon about 3/4" full with water, making sure it is free
of any impurities
- check the float of the plastic cylinder
- put back the siphon, being careful not to empty it, and secure
it with the clip.

The plastic cylinder inside the siphon has the job of preventing com-
bustible gas coming out into the surroundings if the appliance is start-
ed without first creating the head of water in the siphon.
Repeat this operation during routine and extraordinary maintenance
operations.
- Position the mode selector (1 - fig. C) to
1
fig. C
- Position the system's master switch to the "on" position.
- Adjust the ambient thermostat to the desired temperature (~20°C)
or, if the system is equipped with a programmable thermostat or
timer, make sure it is "active" and adjusted (~20°C)
- Position the mode selector (1 - fig. C) to
ter) depending on the type of operation chosen.
- Every time the boiler is powered, an automatic bleed cycle begins
(lasting about 2 minutes).
- The two digits on the display light up alternately during this phase
(fig. D).

- To interrupt the automatic venting cycle, unscrew the 4 Allen
screws (A), remove the control panel (B) and press the combus-
tion analysis button "CO" (C) (fig. E).

SUMMER : with selector in this position, only the conventional
domestic hot water function is activated. The display alternates be-
tween the DHW temperature (fig. F) and the preheating status (P0
not active, P1 active - fig. H).
WINTER : with selector in this position, both the heating and do-
mestic hot water functions are activated. The display shows the out-
let temperature of the heating water (fig. G) and the domestic hot
water (fig. F) alternately to the preheating status (P0 not active, P1
active - fig. H).
ON-OFF PRE-HEATING MODE
the domestic hot water exchanger hot, to reduce standby times when
a request is made.
By turning the selector to this position it is possible to activate or de-
activate the pre-heating (P0 not active, P1 active - fig. H) in summer
and in winter.
