flue, NO check valves must be installed.
To avoid corrosion phenomena, convey the GAHP-AR
acid condensate discharge to the base of the flue gas
exhaust duct.

AY00-120 UNIT FLUE GAS CONDENSATE
DISCHARGE
The AY00-120 unit is a condensing boiler which therefore pro-
duces condensation water from combustion fumes.
Condensate acidity and exhaust regulations
The flue gas condensate contains aggressive acid sub-
stances. Refer to applicable regulations in force for con-
densate exhaust and disposal.
If required, install an acidity neutraliser of adequate ca-
pacity.
Do not use gutters to discharge the condensate
Do not discharge the fume condensate in gutters, due to
the risk of materials corrosion and ice formation.
AY00-120 Unit flue gas condensate fitting
The connection for flue gas condensate discharge is located on
the right side of the appliance at the connection plate (Figure
1.3
▶
The condensate discharge pipe must be connected to a
suitable discharge manifold.
▶
The junction between the pipe and the manifold must re-
main visible.
▶
The connection of the discharge to the sewerage system
must be made at atmospheric pressure, i.e. by dripping into
a siphoned container connected to the sewerage system.
Flue gas condensate discharge manifold
If necessary the condensate discharge manifold may be in com-
mon between the 2 units the Gitié package consists of.
To make the condensate discharge manifold:
▶
Size the ducts for maximum condensation capacity (Table
▶
Use plastic materials resistant to acidity pH 3-5.
▶
Provide for min. 1% slope, i.e. 1 cm for each m of the length
(otherwise a booster pump is required).
▶
Prevent icing.
▶
Dilute, if possible, with domestic waste water (e.g. bath-
rooms, washing machines, dish washers...), basic and neu-
tralising.

DEFROSTING WATER DRAINAGE
Defrosting
In winter, frost may form on the finned coil and the appli-
ance performs defrosting cycles.
Collection basin and drainage system
▶
Provide for a collection basin or containment rim and a dis-
charge system of the defrosting water, to avoid overflowing,
icing and damage.

WARNINGS
General warnings
Read the warnings in Chapter III.1
p. 4, providing im-
portant information on regulations and on safety.
Compliance with installation standards
Installation must comply with applicable regulations in
force, based on the installation Country and site, in mat-
ters of safety, design, implementation and maintenance
of electrical systems.
Installation must also comply with the manufacturer's
provisions.
Live components
After placing the appliance in the final position, and pri-
or to making electrical connections, ensure not to work
on live components.
Earthing
The appliance must be connected to an effective earth-
ing system, installed in compliance with regulations in
force.
It is forbidden to use gas pipes as earthing.
Cable segregation
Keep power cables physically separate from signal ones.
Do not use the power supply switch to turn the ap-
pliance on/off
Never use the external isolation switch (GS) to turn the
appliance on and off, since it may be damaged in the
long run (occasional blackouts are tolerated).
To turn the appliance on and off, exclusively use the suit-
ably provided control device (DDC or external enable).
Control of water circulation pump
The water circulation pumps of the hydraulic circuit
must mandatorily be controlled by the unit's electron-
ic boards. It is not admissible to start/stop circulating
pumps with no enable from the appliance.
4.2
ELECTRICAL SYSTEMS
Electrical connections must provide:
▶
(a) power supply (Paragraph 4.3
▶
(b) control system (Paragraph 4.4
