General Safety Information
9
WARNING:
Installation and service must be performed by a gas
supplier or a licensed qualified installer/service Technician.
9
This manual should be maintained in legible condition and
kept adjacent to the boiler or in a safe place for future refer-
ence.
9
WARNING:
This product is a gas appliance that emits poi sonous
gases; such as CO (Carbon Monoxide). For this reason, it is re-
quired that CO detectors be installed in buildings where the
boiler is installed. Failure to do so may result in severe injury
or death.
9
DANGER:
Make sure the gas on which the boiler will operate is
the same type as that specified on the boiler rating plate and
on the colored sticker near the boiler gas connection.
9
WARNING:
Should overheating occur or the gas supply valve fail
to shut off, do not turn off or disconnect the electrical supply to
the boiler. Instead, shut off the gas supply at a location external
to the boiler.
9
WARNING:
Do not use this boiler if any part has been under
water. Immediately call a qualified service technician to inspect
the appliance and to replace any part of the control system and
any gas control which has been under water.
9
WARNING:
To minimize the possibility of improper operation,
serious personal injury, fire, or damage to the boiler:
− Always keep the area around the boiler free of combustible
materials, gasoline, and other flammable liquids and va-
pors.
− The boiler should never be covered or have any blockage to
the flow of fresh air to the boiler.
9
WARNING:
Risk of electrical shock. More than one disconnect
switch may be required to de-energize the equipment before
servicing.
9
WARNING:
Failure to comply with the the previous warnings
could result in severe personal injury, death or substantial
property damage. Failure to adhere to the guidelines on this
page can result in severe personal injury, death or substantial
property damage.
9
WARNING:
Automatic filling systems are not recommended
with this product as they will continually add fresh water to the
system if there is a leak resulting in the addition of new con-
taminants that could reduce the lifespan of the boiler.
9
WARNING:
There is a risk of pipes freezing if the building is
left unattended for long periods of time, in excess of 12 hrs, in
freezing temperatures. In the event the building will be unoc-
cupied for long periods of time, ensure the proper freeze pro-
tection precautions are taken and that a competent person is
checking the building at regular intervals to prevent freezing.
Failure to do so may result in substantial property damage.
Please consult your qualified service technician with regards to
proper freeze protection precautions.
The following instructions must be observed
− The boiler must only be used for its designated purpose, ob-
serving the Installation Instructions.
− Only use the boiler in combination and with the accesso-
ries and spare parts listed in the Riello Condexa spare parts
catalog.
− Other combinations, accessories and consumables must
only be used if they are specifically designed for the intend-
ed application and do not affect the system performance
and the safety requirements.
− Maintenance and repairs must only be carried out by a qual-
ified service agency at regular intervals.
− You must report the installation of a condensing gas boiler
to the relevant gas and plumbing inspection authority and
have it approved.
− You are only allowed to operate the condensing gas boiler
with the combustion air/flue gas system that has been spe-
cifically designed and approved for this type of boiler.
− Please note that local permission for the flue system and the
condensate water connection to the public sewer system
may be required.
− The hot water distribution system must comply with all ap-
plicable codes and regulations. When replacing an existing
boiler, it is important to check the condition of the entire hot
water distribution system to ensure safe operation.
