Boiler pump (1).
Operates on the primary circuit return. It is part of the pump
body unit realised in composite material.
There is a seat where the automatic air vent valve (2) is housed
with O-ring sealing.
To remove the air vent valve from the pump body, turn the
valve by a quarter turn in an anti-clockwise direction.

Primary heat exchanger
(condensation module).
It is formed by a casing that contains 3 or 4 (
according to the
model
) coil-shaped elements.
Each element is made up from 4 elliptical spirals (3).
The internal part is realised in stainless steel and makes up the
sealed combustion chamber and the condensation chamber
(2), the external part (casing) is realised in composite mate-
rial and also encloses the flue hood (4) for the evacuation of
combustion products.
VICTRIX X 12 2 I:
The first two elements are affected directly by the action of
the cylindrical burner applied to the front, while the third is
arranged in the condensation chamber, which is separated from
the combustion chamber by sheet steel
(see flue circuit)
.
VICTRIX 26 2 I and VICTRIX X 24 2 I:
The first three elements are affected directly by the action of
the cylindrical burner applied to the front, while the fourth is
arranged in the condensation chamber, which is separated from
the combustion chamber by sheet steel
(see flue circuit)
.
To reduce head losses to a minimum and increase the flow rate
available to the system, the flow is made up from the parallel
connection of the first two elements, the return, instead is
made up from the parallel connection of the last two elements
(1 element for VICTRIX X 12 2 I).
The heat exchanger inlet is connected to the pump flow and the
outlet, on which the NTC central heating probe is positioned
(1), is connected to the primary circuit flow.
The coupling to the primary circuit flow and return pipes
is the push-fitting type with O-ring seal and blocked by the
relevant clips.
The condensate drain is also found in the lower part.
To ease the escape of any air bubbles still present in the coils,
there is a manual air vent in the upper part of the module
(5).
