standard with an anti-freeze function that activates
the pump and burner when the system water
anti-freeze function is only guaranteed if:
- the boiler is correctly connected to gas and
electricity power supply circuits;
- the boiler is powered constantly;
- the boiler is not in no ignition block (Par. 2.5);
- the boiler essential components are not faulty.
In these conditions the boiler is protected against
freezing to an environmental temperature of -5°C.
Minimum temperature -15°C. If the boiler is
installed in a place where the temperature falls
below -5°C and in the event there is no gas, or the
boiler goes into ignition block, the appliance may
freeze.
To prevent the risk of freezing follow the instructions
below:
- Protect the central heating circuit from freezing by
introducing a good quality anti-freeze liquid
carefully following the manufaturer's instructions
regarding the percentage necessary with respect to
the minimum temperature required for preserving
the system.
The Boiler is made from materials that are
resistant to ethylene and propylene glycol-based
anti-freeze liquids.
For life and possible disposal, follow the
supplier's instructions.
- Protect the condensate drain trap and circuit
board against freezing by using an accessory
that is supplied on request (anti-freeze kit)
comprising two electric heating elements, the
relevant cables and a control thermostat
(carefully read the installation instructions
contained in the accessory kit pack).
Boiler anti-freeze protection is thus ensured only
if:
- the boiler is correctly connected to gas and
electricity power supply circuits and powered;
In these conditions the boiler is protected against
freezing to temperature of -15°C.

the temperature falls below 0°C the domestic

cleaning products (Fernox) to remove any
deposits that could compromise correct boiler
operation.

INSTRUCTIONS FOR USE
AND MAINTENANCE.
2.1 CLEANING AND MAINTENANCE.
Attention: the heating systems must undergo
periodical maintenance (regarding this, see in
the section dedicated to the maintenance / Hunt
Heating authorised service engineer, relative to
“yearly appliance check and maintenance”) and
regular combustion and energy efficiency
checks in compliance with AS 5601.
This ensures that the optimal safety,
performance and operation of the boiler remain
unchanged over time.
We recommend your appliance is service
annually.
USER
2.2 GENERAL WARNINGS.
Use of the boiler by unskilled persons or
children is strictly prohibited.
If temporary shutdown of the boiler is required,
proceed as follows:
a) drain the heating system if anti-freeze is not
used;
b) shut-off all electrical, water and gas supplies.
In the case of work or maintenance to structures
located in the vicinity of ducting or devices for
flue extraction and relative accessories, switch
off the appliance and on completion of
operations ensure that a qualified Hunt Heating
technician checks efficiency of the ducting or
other devices.
Never clean the appliance or connected parts
with easily flammable substances.
Never leave containers or flammable substances
in the same environment as the appliance.
- the appliance power cable must not be replaced
by the user;
- in the event of damage to the cable, switch off
the appliance and contact a qualified technician;
- if the appliance is not to be used for a certain
period, disconnect the main power switch.
t Attention: the use of components involving
use of electrical power requires some
fundamental rules to be observed:
- do not touch the appliance with wet or moist
parts of the body; do not touch when barefoot.
