Riello RESIDENCE KIS Installer And User Manual page 5

3.4 Installation room
The Residence KIS boiler can be installed in various types of room, as long as the discharge of
the combustion product and the combustion air suction are outside the room itself.
In this case the room does not need any ventilation opening since the Residence KIS boilers
have a combustion circuit that is "airtight" with respect to the installation environment.
b
Consider the clearances necessary to access safety and adjustment devices and to
perform maintenance operations.
b
Check that the electric protection level of the appliance is adapted to the installation
room characteristics.
b
If the boilers are supplied with fuel gas of a specific weight greater than that of the air, the
electric parts will have to be positioned more than 500mm above ground level.
3.5 Installation on appliances that are old or that need to be
updated
When the Residence KIS boiler is installed in old systems or systems being updated, check that:
- The flue is suitable for the temperature of the combustion products with condensation, cal-
culated and built according to Standard, is as straight as possible, airtight, insulated and has
no blockages or narrow sections. It is equipped with appropriate condensate collection and
discharge systems
- The electrical system is installed in compliance with the specific standards and by qualified
personnel
- The fuel supply line and eventual tank (LPG) are made according to specific Standards
- The expansion tank ensures the total absorption of the dilatation of the fluid contained in the
system
- The flow rate and head of the circulator are suitable to the characteristics of the system
- The system is washed, cleansed of any mud, build-up, vented and sealed. It is recommended
that a magnetic filter be installed on the system's return line
- The boiler condensate drain system (siphon) is connected and routed to the collection of
"white" water.
3.6 Installation regulations
The installation must be carried out by qualified personnel, in compliance with the following
reference standards: UNI 7129-7131 and CEI 64-8.
Always comply with local standards of the Fire Department, the Gas Company and with possible
municipal dispositions.
POSITION
Residence is a wall-hung boiler for heating and for the production of hot water, that comes in two
categories, depending on the type of installation:
- B23P-B53P boiler type - forced open installation, with flue gas discharge pipe and pick-up of
combustion air from the installation area. If the boiler is not installed outdoors, air intake in the
installation area is compulsory.
- C(10), C13,C13x; C33,C33x; C43,C43x; C53,C53x; C83,C83x, C93,C93x boiler type: ap-
pliance with airtight chamber, with flue gas discharge pipe and pick-up of combustion air from
outside. It does not require an air intake point in the installation area. This type MUST be
installed using concentric pipes, or other types of discharge designed for condensing boilers
with an airtight chamber.
Residence can be installed indoor and outdoor, in a partially protected place (i.e. a place where
the boiler is not exposed to direct contact or infiltration of rain, snow or hail) and in compliance
with local and national regulation. The boiler can operate in a temperature range from >0°C to
+60°C.
Residence 25 KIS can also be installed outdoor in the built-in unit.
ANTI-FREEZE SYSTEM
The boiler is fitted as standard with an automatic anti-freeze system that activates when the
temperature of the water in the primary circuit falls below 5°C. This system is always active and
provides protection for the boiler up to an air temperature in the installation area of 0°C.
b
To take advantage of this protection (based on burner operation), the boiler must
be able to switch itself on; any lockout condition (for ex. due to a lack of gas or
electrical supply, or the intervention of a safety device) therefore deactivates the
protection.
b
When the boiler is installed in a place where there is a risk of freezing, with out-
side air temperatures below 0 °C, an antifreeze heater kit must be used to protect
the DHW circuit and condensation drain (available on request - see catalog) that
protects the boiler up to -15 °C.
b
The installation of the antifreeze heater kit must be carried out only by authorized
personnel, following the instructions contained in the kit.
In normal operating conditions, the boiler can protect itself against frost.
If the machine is left without power for long periods in areas where temperatures may fall below
0°C, and you do not want to drain the heating system, you are advised to add a specific, good
quality antifreeze liquid to the primary circuit. Carefully follow the manufacturer's instructions with
regards not only the percentage of antifreeze liquid to be used for the minimum temperature at
which you want to keep the machine circuit, but also the duration and disposal of the liquid itself.
For the hot domestic water part, we recommend you drain the circuit.
The boiler component materials are resistant to ethylene glycol based antifreeze liquids.
MINIMUM DISTANCES (Fig. 8a-8b)
To ensure access to the boiler for normal maintenance operations, respect the minimum instal-
lation clearances envisaged.
For correct appliance positioning, bear in mind that:
- it must not be placed above a cooker or other cooking device
- it is forbidden to leave inflammable products in the room where the boiler is installed
- heat-sensitive walls (e.g. wooden walls) must be protected with proper insulation.
b
When installing it is ABSOLUTELY NECESSARY to provide the spaces necessary for
the introduction of the instrument for analysing the combustion. We have provided a
sample diagram where the distances between the boiler and wall unit /recess have been
obtained using an instrument with a length of 300 mm. Longer instruments require more
space.
3.7 Installation of condensate drain pipe (Fig. 9)
b
Before starting the boiler, even just temporarily, the SRD device supplied must be instal-
led.The manufacturer does NOT accept liability for damage to persons or objects caused
by the boiler operating without the SRD device being installed correctly.
For the installation proceed as follows:
- remove the plug (T) from the siphon
- fix the SRD device to the siphon, placing the gasket in-between, screwing it on all the way
and checking its seal
- connect the condensate discharge pipe supplied as standard with the product, then drain the
condensate into a suitable drainage system in compliance with current norms.
b
If it is not possible to fit the SRD device due to the interference with other objects under
the boiler, it is possible to fit it in a different position by inserting a connecting pipe
between the SRD device and the siphon in order to provide a fully airtight seal. The SRD
device should always be positioned VERTICALLY in order to ensure it functions correctly
3.8 Instruction for condensation exhaust connection
fig. 1
This product is designed to prevent the escape of gaseous products of combustion through the
condensation drain pipe with which it is equipped, this is obtained by using a special siphon
placed inside the appliance.
b
All components of the product condensation drain system must be properly maintained
in accordance with the manufacturer instructions and cannot be modified in any way.
The condensation exhaust system downstream of the appliance (1) must comply with the rele-
vant legislation and standards.
The construction of the condensation exhaust system downstream of the appliance is the re-
sponsibility of the installer. The condensation exhaust system must be dimensioned and installed
in such a way as to guarantee the correct evacuation of the condensation produced by the ap-
pliance and/or collected by the evacuation systems of combustion products. All the components
of the condensation exhaust system must be made in a workmanlike manner using materials that
are suitable for withstanding the mechanical, thermal and chemical stresses of the condensation
produced by the appliance over time. Note: If the condensation exhaust system is exposed to the
risk of frost, always provide an adequate level of insulation of the pipe and consider any increase
in the diameter of the pipe itself.
The condensation exhaust pipe must always have an adequate slope level to prevent the con-
densation from stagnating and its proper drainage.
The condensation exhaust system must have an inspectable disconnection (2) between the con-
densation exhaust pipe of the appliance and the condensation exhaust system.
The disconnection must be such as to ensure an atmospheric connection between the inside
of the condensation exhaust system pipe and the environment in order to avoid that the down-
stream exhaust pipe of the product can take on positive or negative pressure with respect to the
environment itself. Fig. 1: example of a connection between the condensation exhaust pipe (3)
and the exhaust system (4).
