7 - HYDRAULIC CONNECTION

CONNECTING THE SYSTEM

Make the connections to the corresponding ttings shown in the diagram on the previous page. Make sure the pipes are not placed under

tension or undersized.

IT IS STRONGLY RECOMMENDED TO WASH THE ENTIRE SYSTEM BEFORE CONNECTING THE STOVE IN ORDER TO GET RID

OF RESIDUES AND DEPOSITS.

Always install shutters in the system leading to the stove so as to disconnect it from the hydraulic system should it be

necessary to move it, or when it requires routine and/or special maintenance. Connect the stove using exible pipes

so that the stove is not excessively constrained to the system, and to allow slight movements.

The pressure discharge valve (C) is always connected to a water drain pipe. The pipe must be adequate to support the

water's high temperature and pressure.

It is important that ONLY qualied engineers are used to t and commission the appliance in ALL cases. The installing

engineer MUST hold a QCF recognised biomass qualication. Any company using sub-contractors MUST ensure they also

hold the relevant qualications (ONLY FOR UK).

CLEANING THE SYSTEM

It is mandatory for the connections to be easy to disconnect by way of unions with rotating connections.

Install suitable shutters to cut o the tubes from the heating system. Assembling the safety valve on the system is compulsory.

In order to protect the heating system from damage caused by corrosion, incrustation or deposit build-up, it is important to clean the

appliance before installation, using suitable products, in compliance with Standard UNI 8065 (water treatment of thermal plants for civil

use).

The use of FERNOX PROTECTOR F1 (available at our authorised centres) product is recommended, this provides long-term protection of

heating systems against corrosion and calcium build-up. It prevents the corrosion of the metal parts of the appliance, i.e. the ferrous

metals, copper and copper and aluminium alloys. It also reduces the noise produced by the boiler. Refer to the instructions on the product.

Cleaning should be performed by a qualied technician.

We also recommend the use of FERNOX CLEANER F3 and LEAK SEALER F4, always available from our authorised distribution centres.

FERNOX F3 is a neutral product for rapid and ecient cleaning of heating appliances. It has been designed to eliminate residues, oily

deposits and incrustations from existing appliances of all ages. It can help restore the heating eciency of the boiler and reduce the noise

it generates.

FERNOX F4 is intended to be used with all heating appliances to seal micro fractures that cause small and inaccessible leaks.

FILLING THE SYSTEM

To ll the system, the stove can be equipped with an end piece (optional) with a non-return valve for manual lling of the heating system

(if the optional is not installed, the lling tap on the main boiler will be used). During this operation, any air in the system is released from

the automatic vent valve located under the top.

To ensure the valve vents, it is advisable to loosen the grey cap one turn and leave the red cap blocked (see gure). The lling pressure

of the system WHEN COLD must be 1 bar. During operation, if the system pressure drops (due to evaporation of dissolved gases in the

water) to values lower than the minimum indicated above, the user must use the lling tap to bring the pressure back up to its normal

pressure.

For proper operation of the stove WHEN HOT, the pressure in the boiler must be 1.5 bar.

To monitor the system's pressure, the terminal (optional) is equipped with a manometer.

Upon completion of this operation, always close the tap.
