R
recommends signing a service and maintenance con-
tract with a trained and qualified installer or service agency
that covers annual servicing and condition-based mainte-
nance. Proper maintenance is a fundamental requirement
for safe and efficient operation and long service life.
− The boiler must be serviced annually including the main
burner, ignition system, the entire venting system, and
the combustion air supply. All parts that show any signs of
damage or corrosion must be replaced.
9
WARNING: This product is a gas appliance that emits poi-
sonous gases; such as CO (Carbon Monoxide). For this reason,
it is required that CO detectors be installed in buildings where
the boiler is installed. Failure to do so may result in severe
injury or death.
9
WARNING: when servicing the boiler and venting components
ensure the boiler components and venting components are
installed properly per the Installation, Operation & Service
Instructions for the boiler as well as the vent manufacturer's
installation instructions and the local code having jurisdiction
are followed. Failure to comply may result in substantial prop-
erty damage, severe personal injury, or death.
− The owner and operator is responsible for the operational
safety and regulatory compliance of the heating system.
− Improper installation, adjustment, alteration, service, or
maintenance can cause property damage, personal injury,
or death. Refer to this manual and consult a qualified in-
staller or service agency, or the gas supplier before installa-
tion, service or maintenance.
− The boiler must be installed such that the gas ignition
system components are protected from water (dripping,
spraying, rain etc.) during boiler operation and circulator
replacement, condensate trap, control replacement, etc.
− The boiler must not be installed on carpeting.
9
This product must only be used for the purpose for which it
is designed and made, as specified by
responsibility, contractual or other, for damage to property or
injury to persons or animals caused by improper installation,
adjustment, maintenance or use.
9
If you notice any water leaks, disconnect the boiler from the
main electrical supply and shut off the water supply.
9
Periodically check that pressure in the central heating circuit,
when cold, is approximately 20 psi (1.4 bar) and below the
maximum limit specified for the boiler.
9
If the boiler is not going to be used for an extended period of
time, perform the operations described later in this manual.
9
This instruction manual is an integral part of the boiler. It must
be kept safe and must ALWAYS accompany the boiler, even if it
is sold to another owner or transferred to another user or to
another installation. If you damage or lose this manual, order
a replacement immediately from your local
sistance Center.
9
The equipment without packaging, before being connected to
the hydraulic system and to the gas supply and being electri-
cally powered can be exposed to temperatures ranging be-
tween 39°F (4°C) and 104°F (40°C). Once it is able to activate the
antifreeze functions, it can be exposed to temperatures within
-4°F (-20°C) and 104°F (40°C).
9
Regularly check that the condensate drain is free from ob-
struction.
9
We recommend cleaning inside the heat exchanger once a
year, extracting the fan and burner and removing any instal-
lation debris using a vacuum. This operation should be done
by a qualified installer, service agency or gas supplier only.
9
WARNING: Metal casing is an integral part of the boiler. All
panels, doors and seals must be always in place, fully closed,
during boiler's operation, to prevent any gas or flue leakage
in case of failure.
