Installation; Flue Connection - ACV Solo 18 Installation, Operating And Servicing Instructions

InstallatIon

flue connectIon

- The connections must comply with the NBN D51-003 standard taking into
account local energy suppliers' instructions, fire regulations and regulations
relating to "pollution".
- Owing to its built-in gas/air ratio regulator, the Prestige is, to a large extent,
independent of pressure drops in the air intake and flue-gas exhaust
systems. However, the maximum pressure drop of this system may not be
exceeded; otherwise, the output would diminish. Nevertheless, the gas/
air ratio regulator always guarantees optimal combustion with very low
emissions.
- The horizontal flue gas exhaust ducts must be installed with a sufficient
degree of slope towards the boiler: 3° of slope = 5 mm per metre of duct.
- There must be no obstructions or inlets to other appliances within a radius
of 0.5 metres around the Prestige terminal.
- The maximum pressure drop of the chimney is 130 Pascal. You can
calculate this value using the following table: (please see sample calculation).
- The C33s and C93 configuration enables airtight operation in a pre-
existing chimney. The combustion air crosses the space between the
tubing and the pre-existing chimney. Make sure to clean the pre-existing
chimney thoroughly prior to installation, especially if there is soot or tar
residue. Make sure that there is a clearance area for the combustion air at
least equivalent to the area that would have been provided by separate
concentric ducts or air intake ducts.

Prestige 32 with concentric
chimney duct
The diagram below consists of the following
parts: 2 90° pipe bends + 2 metres of horizontal
pipe + 3 metres of vertical pipe + one vertical
terminal.
The resistance of this system is as follows:
(2 x 10) + (2 x 9) + (3 x 9) + 35 = 100 Pa.
As this value is lower than the maximum
authorised resistance, this installation is
therefore compliant.
