Discharge Of Combustion Products - Riello Condexa Pro Series Manual

DISCHARGE OF COMBUSTION PRODUCTS

The appliance is supplied as standard in type C configuration (C13 - C33 - C53 - C63), offering the possibility to draw air directly
from the installation room or from the outside, in this case with the possibility of having coaxial or split pipes.
It is essential that only specific pipes for condensing boilers are used for extracting the combustion air and that the connection
is made correctly as indicated by the instructions supplied with the smoke accessories. Do not connect the smoke evacuation
ducts of this appliance to those of other appliances unless expressly approved by the manufacturer. Failure to comply with this
warning may result in accumulation of carbon monoxide which can cause serious personal injury or death.
Ensure that the combustion air (intake air) is not contaminated by:
• waxes/chlorinated detergent
• chemical products based on swimming pool chlorine
• calcium chloride
• sodium chloride used for water softening
• refrigerant leaks
• paint or varnish removal products
• hydrochloric acid / muriatic acid
• cements and glues
• antistatic softeners used in dryers
• chlorine used for domestic or industrial purposes as a detergent
• whitener or solvent
• adhesives used to glue construction products and others
• similar products.
To prevent contamination, do not install suction line air intakes and gas flue extraction pipes near:
• dry-cleaners/laundry rooms and factories
• pools
• metallurgy processing plants
• beauty parlours
• fridge repair shops
• photo processing facilities
• body-shops
• plastics manufacturing plants
• furniture workshops and manufacturing plants.
The exhaust duct and the fumes connection must be made in compliance
with the standards, current legislation and local regulations.
The use of rigid ducts that are resistant to temperature, condensation,
mechanical stress and tightness is mandatory.
Non-insulated exhaust ducts are potential sources of danger.
DESCRIPTION
UF (fumes outlet)
AA (air intake)
Check that condensation does not build up along the duct. For this purpose, provide a sloping duct of at least 3 ° towards the
appliance in the presence of a horizontal section. If the horizontal or vertical section is longer than 4 meters, it is necessary
to provide a siphoned drainage of the condensate at the foot of the pipe. The useful height of the siphon must be at least the
value "H" shown in the table. The drain of the siphon must therefore be connected to the sewerage system.
For changes of direction, use a T-fitting with an inspection cap which allows easy periodic cleaning of the pipes.
Always make sure that after cleaning the inspection plugs are hermetically closed with the relative seal intact.
