TECHNICAL CHARACTERISTICS
GENERAL RECOMMENDATIONS FOR CHIMNEY CONNECTION
Essential recommendations for safety
•
Do not install the boiler into a common flue piping with any other gas or oil
appliances. This will cause flue gas spillage or appliance malfunction.
•
Verify installed combustion air and flue piping are sealed gas tight and meet all
provided instructions and applicable codes and standards.
•
Failure to properly support the flue system can cause the flue system to fail,
resulting in substantial property damage, serious injury, or death.
•
A byproduct of any gas/oil fired appliance is carbon monoxide. Failure to install
carbon monoxide detectors with alarms can result in serious injury, or death. Refer
to applicable local regulations.
Essential recommendations for the correct operation of the appliance
•
A condensation outlet connected to the sewer must be fitted close to the boiler to
prevent the condensation products from the flue pipe from running into the boiler.
•
Install a condensate neutralisation system if required by national and/or local
regulations and have it cleaned regularly.
•
Only use flue system components from the same manufacturer to connect this
appliance and ensure that the pipe and connection diameters all match.
•
Make sure to secure the flue piping to a solid structure.
•
Exclusively use provided brackets to support the flue system.
•
Install the horizontal flue pipes with a slight slope of 5 cm per meter (3°), so that the
acid condensation water flows to a condensate recovery container and does not
damage the heating body.

1. Each elbow and straight element will be secured at the sleeve.
2. In case the straight element before or after the first elbow is shorter than 25 cm,
secure the straight element after the elbow using a bracket.
3. In case a straight (horizontal or sloped) element is longer than 1 m, support the element in
its center using a clamp, making sure to allow free movement of the pipe.
4. Secure with a clamp every 2 meters in vertical piping/1 meter in horizontal/sloped
piping, making sure to distribute the clamps evenly on the length of piping.
•
If the appliance is provided with a condensate drain assembly, make sure to install
the complete assembly on the boiler. If the assembly is incomplete, replace the entire
assembly.
•
Make sure that the condensate drain assembly is filled with water before starting
up the boiler and check regularly the water level. Fill with water as necessary.
•
It is mandatory to ventilate the boiler room. The high or low air vent opening
dimensions depend on the boiler power and the boiler room size. Refer to the local
regulations in force.
•
If the combustion air inlet is located in an area likely to cause or contain
contamination, or if products which could contaminate the air cannot be removed,
the combustion air must be repiped and terminated at another location.
•
Pool, laundry, common household, and hobby products often contain fluorine
or chlorine compounds, which can form strong acids and corrode the internal
components and flue system.
•
In the case of parallel flue systems, make sure to maintain sufficient distance
(at least 40 mm) between the boiler flue piping and combustible materials, and
between the flue pipe and air inlet pipe if the latter is made of plastic material.
•
Do not use screws to fasten together any flue pipe elements or any PP air inlet
elements.
•
Do not bond piping elements together using glue (e.g. silicone) or foam (e.g. PUR).
General remark
•
For safety reasons and to make assembly easier, it is recommended to prefer the
use of concentric flue pipes when possible.
•
It is recommended to isolate the flue piping in damp rooms to prevent condensation
water from forming on the piping and drip.
•
When cutting the pipes to dimension, make sure to cut squarely and deburr the
edges to prevent seals from being incorrect or damaged.
•
To make piping assembly easier, exclusively use a mixture of water and soap (1%)
on the extremity of the pipe to be fit in.
•
When fitting metal flue pipes, make sure to always fit the pipe into the sleeve to
the end stop.
•
When fitting plastic flue pipes, make sure to allow material expansion by leaving
about 10 mm between the pipe end and the sleeve end stop.
•
Make sure to install the piping without any strain.
•
Make sure to install an inspection opening in the flue system.
•
When connecting the flue pipes, make sure not to exceed the maximum length
recommended for the product, otherwise the system power might decrease.
•
ACV-approved components will be used for the chimney connection. Failure to do
so will make any warranty claim void.
•
For C63 connection type (not allowed in Belgium), make sure to use the correct
piping material according to the resistance to temperature, pressure, chemical
composition of flue, condensation and soot. A code (as explained in EN 1443),
marked on the pipe, allows to determine if the material complies with the flue
system requirements.
