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

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.

2 INSTRUCTIONS FOR USE AND MAINTENANCE.

To access the control panel, remove the protec-tion panel from the casing front by unscrewing the bolt and removing it as shown in Fig. 3-5.

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.

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 structureslocated 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.

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.

- 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.

When commissioning the boiler, ensure the appliance checklist, located at the rear of this instruction booklet is completed.

To commission the boiler:- ensure that the type of gas used corresponds to boiler settings recorded on the appliance data plate;- check connection to a 230V-50Hz power mains, correct L-N polarity and the earthing connection;- switch the boiler on and ensure correct ignition;- ensure the gas inlet static pressure is correct, 1.5 Kpa- check that the gas maximum and minimum relative pressure values correspond to those given in the handbook, Par. 3.16;- check activation of the safety device in the event of no gas, as well as the relative activation time;

- check activation of the main switch located upstream from the boiler and in the boiler;- check that the intake and/or exhaust terminals are not blocked;- check activation of the “no air” safety pressure switch;- ensure activation of all adjustment devices;- ensure seali- check ventilation and/or aeration of the installation room where provided.
