• Carefully read the warnings in this instruction book-

let since they provide important information on safe
installation, use and maintenance.

• This instruction booklet is an integral part of the

product and must be carefully kept by the user for fu­ture reference.

• If the unit is sold or transferred to another owner or if

it is to be moved, always make sure that the booklet
accompanies the boiler so that it can be consulted
by the new owner and/or installer.

• Installation and maintenance must be carried out by

professionally qualified personnel, according to cur­rent regulations and the manufacturer's instructions.

• Incorrect installation or poor maintenance can cause

damage or physical injury. The manufacturer de­clines any responsibility for damage caused by er­rors in installation and use or by failure to follow the
manufacturer's instructions.

• Before carrying out any cleaning or maintenance op-

eration, disconnect the unit from the electrical power
supply using the switch and/or the special cut-off de­vices.

• In case the unit breaks down and/or functions poorly,

deactivate it, do not make any attempt to repair it or
directly intervene. Contact professionally qualified
personnel. Any repair/replacement of products must
only be carried out by qualified professional person­nel using exclusively genuine parts. Failure to com­ply with the above could affect the safety of the unit.

• Periodical maintenance carried out by qualified per­sonnel is essential for guaranteeing good operation
of the unit.

• This unit must only be used for the purpose for which
it was designed. Any other use is considered im­proper and therefore hazardous.

• After removing the packing, check the integrity of the
contents. Packing materials must not be left within
the reach of children as they are potentially hazard­ous.

• In case of doubt do not use the unit, and contact the
supplier.

• The images shown in this manual are a simplified
representation of the product. In this representation
there may be slight, unimportant differences with the
supplied product.

1. Operating instructions

1.1 Introduction

The GFN K is a new boiler in cast iron for heating and domestic hot water production, using solid fuels (coal and wood),
oil (with optional kit) or pellets (with optional kit). The boiler shell consists of elements assembled with nipples; the profile
of the elements is particularly careful and the optimum finning ensures high heat efficiency, performance and consider­able energy saving. The combustion chamber is specially designed to take large pieces of wood; loading is by means
of the large top door. The combustion chamber is completely wet, to ensure long life and high efficiency. The hot water
tank is equipped with an electric heater to ensure domestic hot water production even in summer.

1.3 Turning on and off

Fuel

The boiler must be used with coal or natural and untreated wood. Pressed fuels and briquettes can be used, provided
they are entirely in wood. An oil or pellet burner can be installed on the boiler with the special optional conversion kit.
Refer to the instructions supplied with the burner.

B

The burning of waste, plastic or liquids can create poisonous burnt gases with the risk of poisoning, death or
explosion.

• Only use the fuels indicated.

• In the presence of risk of explosion, fire, burnt gases or fumes, put the boiler out of service.

• The boiler must only be operated by adults who have read the instructions and how to use it.

• The user is only authorised to start the boiler, set the temperature, clean and decommission it.

• Make sure unsupervised children keep away from the boiler when it is operating.

• Do not burn flammable liquids or use them to increase boiler performance.

• Clean the boiler surface with non-flammable agents only.

• Do not place flammable objects on or near the boiler.

• Do not store flammable materials (e.g. wood, paper, petroleum, gas oil) in the boiler installation room.
Wood is an extremely heterogeneous fuel for type, moisture content, shape and size. Boiler efficiency also depends on

the type of wood used and its moisture content, as well as by its size and method of loading. Excellent quality woods
are oak, ash, beech, maple and fruit trees except cherry; good quality woods are chestnut and birch; sufficient quality
woods are limewood, poplar and willow. In general, resiniferous woods are mediocre fuels. The higher the moisture con­tent, the lower the heating power. The use of damp fuels causes a loss of efficiency. Use wood logs dried outdoors and
in the natural state (stored for 2 years with max. humidity of 20%).

Boiler lighting

• Open the bottom door and remove any ash present in the combustion chamber. Close the bottom door.

• Switch on the power to the unit. Turn the lighting switch to ON and the Summer/Winter switch to .

• Turn the thermostatic control knob 6 to the required temperature value.

• Fully open the draught control on the flue.

• Open the top door. Place a little paper and dry kindling on the burner grate.

• Light the fuel and add a few pieces of slightly larger wood.

• Close the door and wait for a first bed of embers to form.

• Open the top door slowly.

• Spread the embers evenly on the burner with a poker.

• After the bed of embers has formed, load small and medium-size pieces of wood or coke coal.

B

- Pieces that are too long do not fall regularly, causing empty spaces with the creation of areas of unburnt
wood.

- Pieces that are too short cause uneven air passages, with a decrease in power and efficiency

- Always open the top door slowly in order to prevent puffs and smoke.

- Do not open the bottom door during operation.

- During the loading stage avoid keeping the top door open for long periods.

- In case of operation with reduced performance, distilled gases at low temperature may form, which can cause
smoke poisoning if breathed.

- If dense smoke is visible, do not breathe.

- Make sure the installation room is well-ventilated.

- Clean the boiler and exhaust gas ducts as prescribed.

Boiler shutdown

To shut down the boiler, allow all the fuel to be burned.

Shutdown for short periods

For short shutdown periods, turn the lighting switch to OFF after the fuel has finished and the boiler has cooled.

• Clean the loading door support surfaces and the loading compartment.

• Remove the ashes and clean the combustion chamber.

• Close the ash compartment door and the loading door.
