INSTALLATION MANUAL
1 - GENERAL SAFETY DEVICES
The boilers produced in our plants are built with great attention to
detail and every component is checked in order to protect users
and installers from injury. After working on the product, qualified
personnel must check the electrical wiring, in particular the stripped
part of conductors, which must not stick out from the terminal board,
avoiding possible contact with live parts of said conductor.
This instruction manual, together with the user manual, are integral
parts of the product: make sure it remains with the appliance, even
if it is transferred to another owner or user, or moved to another
heating system. In case of loss or damage, please contact your local
Technical Assistance Service for a new copy.
Boiler installation and any other assistance and maintenance opera-
tions must be carried out by qualified personnel according to the
provisions of the legislation in force.
The installer must instruct the user about the operation of the appli-
ance and about essential safety regulations.
This appliance should not be operated by children younger than 8
years, people with reduced physical, sensory or mental capacities,
or inexperienced people who are not familiar with the product, un-
less they are given close supervision or instructions on how to use it
safely and are made aware by a responsible person of the dangers
its use might entail. Children must not play with the appliance. It is
the user’s responsibility to clean and maintain the appliance. Children
should never clean or maintain it unless they are given supervision.
This boiler must only be used for the application it was designed for.
The manufacturer declines all contractual and non-contractual liability
for injury to persons or animals or damage to property deriving from
errors made during installation, adjustment and maintenance and
from improper use.
After removing the packaging, make sure the contents are in good
condition and complete. Otherwise, contact the dealer from whom
you purchased the appliance.
When the product reaches the end of its life it should not be disposed
of as solid urban waste but should be brought to a separated waste
collection facility.
The safety valve outlet must be connected to a suitable collection
and venting system. The manufacturer declines all liability for any
damage caused due to any operation carried out on the safety valve.
Dispose of all the packaging materials in the suitable containers at
the corresponding collection centres.
Dispose of waste by being careful not to harm human health and
without employing procedures or methods which may damage the
environment.
During installation, inform the user to:
- in the event of water leaks, the water supply must be shut off and
the Technical Assistance Service must be contacted immediately.
- it is necessary to periodically check that the operating pressure of
the hydraulic system is above 1 bar. If necessary, reset the pres-
sure as indicated in the paragraph entitled “Filling the system”
- if the boiler is not used for a long time, the following operations are
recommended:
- turn the main switch of the appliance and the main switch of the
system to the “off” position
- close the fuel and water taps of the heating system
- drain the heating system to prevent freezing.
For safety, always remember that:
it is dangerous to activate electrical devices or appliances (such as
switches, home appliances, etc.) if you smell gas or fumes. In the
event of gas leaks, ventilate the room opening doors and windows;
close the main gas tap; contact the Technical Assistance Service or
professionally qualified personnel immediately
do not touch the boiler while barefoot, or if parts of your body are
wet or damp
before any cleaning operations, disconnect the boiler from the mains
power supply by turning the two-position system switch and the main
control panel switch to the “OFF” position
do not modify safety and adjustment devices without the manufac-
turer’s permission and relative instructions
do not pull, disconnect or twist the electric cables coming out of the
boiler, even when it is disconnected from the mains power supply
avoid covering or reducing the size of the ventilation openings in the
installation room
do not leave inflammable containers and substances in the installa
-
tion room
keep packaging materials out of the reach of children
it is forbidden to obstruct the condensate drainage point.
2 - DESCRIPTION
Quadra Green R.S.I.
is a type C wall-mounted condensing boiler capable
of operating under different conditions through a series of jumpers on the
electronic board (as described in “Boiler configuration”):
MODE A:
heating only without any external storage tank connected.
The boiler does not supply domestic hot water.
MODE B:
heating only with a thermostatically controlled external storage
tank connected: in this condition, with every heat request from the storage
tank thermostat, the boiler supplies hot water for the preparation of the
domestic hot water.
MODE C:
heating only, with the connection of an external storage tank (ac-
cessory kit available upon request) (managed by a temperature probe) for
preparing domestic hot water. When connecting the storage tank not sup-
plied by us, make sure that the NTC probe has the following characteristics:
10 kOhm at 25°C, B 3435 ±1%.
According to the flue gas discharge device, the boiler is classified in
categories B23P, B53P, C13, C33, C43, C53, C63, C83, C93, C13x, C33x,
C43x, C53x, C63x, C83x, C93x.
In configuration B23P and B53P (when installed indoors), the appliance
cannot be installed in bedrooms, bathrooms, showers or where there are
open fireplaces without a proper air flow. The room where the boiler is
installed must have proper ventilation.
In configuration C, the appliance can be installed in any type of room and
there are no limitations due to ventilation conditions or room volume.
3 - INSTALLATION
3.1 Installation regulations
Installation must be carried out by qualified personnel, in accordance with
the regulations in law.
POSITION
The boiler 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). The boiler can operate in a temperature range from 0°C
to +60°C. For further details, refer to “Anti-freeze system” section.
ANTI-FREEZE SYSTEM
The boiler is fitted as standard with an automatic anti-freeze system that
actives when the water temperature in the primary circuit falls below 5°C.
This system is always active, guaranteeing boiler protection down to an
installation area temperature of 0°C.
To take advantage of this protection, based on the burner operation, the
boiler must be able to switch itself on; any lockout condition (i.e. due to
a lack of gas or electrical supply, or the intervention of a safety device)
therefore deactivates the protection.
By using a specific accessory, the DHW circuit can be protected in case of
temperatures lower than 0°C up to -10°C. This system is made by a series
of electrical resistances.
To use the anti-freeze protection, an electrical supply is required; this
means that any blackout or disconnection will deactivate the protection.
The anti-freeze protection is also active when the boiler is on stand-by. In
normal operation conditions, the boiler can protect itself against freezing.
In areas where temperatures may fall below 0°C, or when the machine is
left unpowered for long periods, you are advised to use a good quality anti-
freeze liquid in the primary circuit to avoid the risk of freezing if you do not
want to drain the heating system.
Carefully follow the manufacturer’s instructions with regards not only the
percentage of anti-freeze 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 anti-freeze liquids.
MINIMUM DISTANCES
In order to have access to the boiler to perform regular maintenance opera-
tions, respect the minimum clearances foreseen for installation (fig. 9).
For correct appliance positioning:
- do not place it on a cooker or other cooking device
- do not leave inflammable products in the room where the boiler is installed
- heat sensitive walls (for example, wooden walls) must be protected with
proper insulation.
In some parts of the manual, some symbols are used:
WARNING
= for actions requiring special care and adequate preparation
FORBIDDEN
= for actions that MUST NOT be performed
DHW functions refer only if a water tank is connected (accessory available on
request).
