POSITION
EXCLUSIVE is a wall-hung boiler for heating and for the production of hot
water. There are two categories, depending on the type of installation:
-
pipe and pick-up of combustion air from the installation area. If the
boiler is not installed outdoors, the air intake in the installation area is
compulsory;
-
discharge pipe and pick-up of combustion air from outside.
It does not require an air intake point in the installation area.
discharge designed for condensing boilers with an airtight chamber.
The boiler can be installed indoor and outdoor, in a partially protected
range from -5°C to +60°C.
ANTI-FREEZE SYSTEM
actives when the water temperature in the primary circuit falls below 5°C.
This system is always active, guaranteeing boiler protection down to an
installation area temperature of -5°C.
b To take advantage of this protection, based on the burner
operation, the boiler must be able to switch itself on; any
lockout condition (i.e. due to a lack of gas or electrical supply,
or the intervention of a safety device) therefore deactivates the
protection.
Under normal operating conditions, the boiler can self-protect itself from frost.
In areas where temperatures may fall below 0°C, or when the machine is
left unpowered for long periods, you are advised to use a good quality anti-
freeze liquid in the primary circuit to avoid the risk of freezing if you do not
want to drain the heating system.
Carefully follow the manufacturer’s instructions with regards not only the
percentage of anti-freeze liquid to be used for the minimum temperature
at which you want to keep the machine circuit, but also the duration and
disposal of the liquid itself. For the hot domestic water part, we recommend
you drain the circuit. The boiler component materials are resistant to ethylene
available for boilers installed outdoors in a partially protected place.
MINIMUM DISTANCES (g. 6a-6b)
To ensure access to the boiler for normal maintenance operations, respect
the minimum installation clearances envisaged.
For correct appliance positioning, bear in mind that:
- it must not be placed above a cooker or other cooking device
-

- heat-sensitive walls (e.g. wooden walls) must be protected with proper

that the three-way valve cycles from heating to DHW and vice versa for
about ten times (in this situation, the boiler will go into alarm due to lack
of gas, therefore reset it whenever this is proposed).

It is obligatory to make the connection with a safe ground/earth, in
compliance with current directives.
