Warnings And Safety - Riello RESIDENCE HM Series Instructions For The User

1 WARNINGS AND SAFETY

b
The boilers manufactured in our factories are checked
even in the smallest details in order to protect users
and installers against possible injury. After working on
the product, qualified personnel must check the elec-
trical wiring, in particular the stripped part of leads,
which must not protrude from the terminal board and
avoiding possible contact with live parts of the leads
themselves.
b
This manual is an integral part of the product: make
sure it is always kept with the appliance, even if
the latter is transferred to another owner or user, or
moved to another heating system. In case of loss or
damage, please contact your local Technical Assis-
tance Centre for a new copy.
b
This appliance should not be operated by children un-
der the age of 8, people with reduced physical, sen-
sory or mental capacities, or inexperienced people
who are not familiar with the product, unless 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 supervised.
b
Boiler installation and any other assistance and main-
tenance operation must be carried out by qualified
personnel according to the current regulations and in
compliance with UNI 7129-7131 and updates.
b
Boiler maintenance must be performed at least once
a year and scheduled in good time with the Technical
Service Centre.
b
The installer must instruct the user about how the ap-
pliance works, and the essential safety rules.
b
The user must respect the warnings given in this
manual.
b
This boiler is intended for the use for which it was ex-
pressly designed. The manufacturer accepts no con-
tractual or non-contractual liability for any damage or
harm caused to people, animals and property due to
installation, adjustment and maintenance errors or to
improper use.
b
After removing the packaging, make sure the con-
tents are in good condition and complete. Otherwise,
contact the dealer from who you purchased the ap-
pliance.
b
The safety valve outlet must be connected to a suita-
ble collection and venting system. The manufacturer
disclaims liability for any damage caused by the inter-
vention of the safety valve.
b
Dispose of all the packaging materials in the relative
containers at the corresponding collection centres.
b
When disposing of waste, be careful not to harm hu-
man health or employ procedures or methods which
may damage the environment.
At the end of its life, the product should be not be
disposed of as solid urban waste, but rather it should
be handed over to a differentiated waste collection
centre.
During installation, the user must be informed that:
- in the event of water leakage, the water supply must be
shut off and the Technical Assistance Centre must be
notified without delay
- the operating pressure of the hydraulic system must be
checked regularly to ensure it is higher than 1 bar. If
necessary, restore pressure by opening the filling tap (the
operating pressure of the hydraulic system must be checked
regularly to ensure it is higher than 1 bar. If necessary,
restore pressure by opening the filling tap (outside the
boiler)
- wait for the pressure to increase: check on the boiler
display that the value reaches 1-1.5 bar; then close the
filling tap (outside the boiler).
If the boiler is not used for a long time, you are advised to
carry out the following operations:
- set the device to OFF and the main switch of the system
to 'off'
- close the gas and water taps on both the heating and
domestic hot water circuits
- empty the heating and DHW system if there is a risk of
freezing.
For reasons of safety remember that:
a
It is forbidden to activate electric devices or applianc-
es such as switches, household appliances and so
on if you notice a smell of fuel or unburnt fuel. In this
case:
- ventilate the room by opening the doors and win-
dows;
- close the fuel shut-off device;
- arrange for the Technical Assistance Centre or pro-
fessionally qualified personnel to intervene promptly.
a
It is forbidden to touch the appliance while barefoot or
if parts of your body are wet.
a
It is strictly prohibited to carry out any technical or
cleaning work before disconnecting the appliance
from the power supply by placing the boiler to "OFF"
and the also setting the main switch of the system to
"OFF".
a
Do not modify the safety or adjustment devices with-
out the manufacturer's authorisation and precise in-
structions.
a
It is forbidden to pull, detach or twist the electrical
cables from the appliance, even if it is disconnected
from the mains supply.
a
Do not cover or reduce the size of the ventilation
openings in the room where the boiler is installed.
a
It is forbidden to leave flammable containers and sub-
stances in the room where the appliance is installed.
a
It is forbidden to leave the packaging material within
children's reach, as it may be a potential source of
danger. Dispose of it responsibly, in accordance with
the legislation in force.
a
It is forbidden to obstruct the condensate drain outlet.
The condensate drain pipe should be facing the dis-
charge pipe, preventing the formation of further drain
pipes.
a
It is forbidden to intervene in any way on the gas
valve.
a
It is forbidden to intervene on sealed elements.
2 DESCRIPTION
RESIDENCE HM boilers have a new ACC (active combustion control)
combustion control system. This innovative control system, developed
by Riello, guarantees functionality, efficiency and low emissions in all
circumstances. The ACC system uses an ionization sensor immersed in
the burner flame which, through its information, allows the control board
to act on the gas valve that regulates the fuel. This sophisticated control
system allows self-regulation of combustion, eliminating the need for ini-
tial calibration. The ACC system is able to adapt the boiler to operate with
different gas compositions, different pipe lengths and different altitudes
(within the expected design limits). The ACC system is also able to carry
out a self-diagnosis which blocks the burner before exceeding emission
thresholds higher than the limits allowed by the regulations.
