ENERGY TOP B

3.5 Flue connection

Important

The unit is a B23 type with combustion air drawn from the installation room and fume ex-
haust by means of a fan (operation with flue under pressure) and must be connected to
one of the discharge systems indicated below. Before proceeding with installation, check
and carefully comply with the local regulations and provisions. Also comply with the pro-
visions concerning the positioning of wall and/or roof terminals and the minimum distanc-
es from windows, walls, ventilation openings, etc.
Manifold, ducts and flue must be suitably sized, designed and made in compliance with
the current standards. They must be made of suitable materials, i.e. resistant to heat and
corrosion, smooth on the inside and hermetic. In particular, joints must be condensate-
proof. Also provide for suitable condensate drainage points, connected through a trap to
prevent the condensate produced in the flues from running into the generators.
B
The unit is equipped with one (models ENERGY TOP B 80 - 125) or two (mod-
els ENERGY TOP B 160 - 250) separate Ø80 flue connections for the two burn-
er - exchanger units.
The combustion circuits of the two units are completely independent. When
joining the two fume outlets to a single flue or manifold (in case of a single mod-
ule or connection in cascade) it is necessary to install a fume anti-backflow val-
veon each outlet to prevent operation anomalies or the creation of hazardous
conditions. Make sure to use the optional FERROLIkits , provided with special
anti-backflow valves.
Before carrying out the flue connection, make sure to fill the condensate trap
A
with approx. 0.5 litres of water through the flue connections.
Connection with separate pipes
Separate Ø80 ducts can be connected directly to the unit Insert the seal 1KWMA84A on
the Ø80 pipes leaving the unit and make it adhere to the upper wall of the cabinet
Before installation, make sure the maximum permissible length has not been exceeded,
by means of a simple calculation:
1. Establish the layout of the system of split flues, including accessories and outlet ter-
minals for each of the two burner/exchanger bodies
2. Consult the table 5 and identify the losses in meq (equivalent metres) of every com-
ponent, according to the installation position
3. Check that the sum total of losses is less than or equal to the maximum permissible
length in table 4.

Direct connection of Ø80 terminals code 041013X0
Each single module can be connected directly to the terminal kits 041013X0 as given in
, even with fig. 37 connection in bank.
Each kit comprises a Ø80 terminal with grille (ref. 3), a seal (ref. 1) and a centring ring
(not used in this model). For models ENERGY TOP B 160 - 250 use 2 kits perENERGY
TOP B 80 - 125module, and 1 kit for models .

Before installing the flues, fill the trap with approx. 0.5 l. of water through the
flue connections.
B
For outside installations make the seal 1 adhere perfectly to the top part of the
cabinet, to prevent possible infiltration of rain and atmospheric agents.
Connection with manifolds
eq
To connect one or more modules in bank to a single flue, it is advisable to use the special
manifolds (optionals) given in the table. The choice of diameter must be made according
to the total power of the bank of units, respecting that given in the table. Use a starting
kit for each bank (containing manifold plug and trap) and a suitable number of manifolds
2.0
(one for each ENERGY TOP B 80 - 125 and two for each ENERGY TOP B 160 - 250).
90° bends and manifold extensions are also available for the flue connection.
