1. Operating instructions
1.1 Introduction
Dear Customer,
Thank you for choosing a FERROLI boiler featuring advanced design, cutting-edge technology, high reliability and qual-
ity construction. Please read this manual carefully since it provides important information on safe installation, use and
maintenance.
FG is a wood-burning steel boiler, with total gasification. It exploits the principle of reverse flame combustion, with gradual burning of the wood, to the advantage long operation times before refuelling. In fact, thanks to a variable-speed fan
located at the back of the boiler, combustion occurs in a negative pressure. the lit wood, placed in a holder above a
special grill, develops a particular type of combustion which, thanks to the high temperature determined by a balanced
supply of primary combustion air from above and secondary air injected through the separation grill, turns the cellulose
into simpler compounds that burn in the underlying combustion chamber with a flame similar to that of natural gas, with
efficiencies exceeding 85%. In the wood loading stage the fan is activated when the door is opened, thus preventing
smoke from escaping.
The outer casing consists of painted steel panels, insulated internally with mineral wood to ensure optimum insulation
of the boiler body. A safety exchanger for eliminating the excess heat can be installed by request.

Fuel
The boiler must only operate with normal and untreated wood. The logs can be 50 cm long for models FG30 and FG40,
and 70 cm for model FG50. Pressed fuels and briquettes can also be used, provided they are entirely of wood.
The burning of waste, plastic or liquids can create dangerous burnt gases with risk of poisoning, death or ex-
B
• Only use the specified fuels.
• 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 are familiar with the boiler instructions and its operation.
• The user is only authorised to start the boiler, set the heating temperature, put it out of service and clean it.
• Keep unsupervised children away from the boiler when it is operating.
• Do not burn liquids or use them to increase boiler performance.
• Only use non-flammable agents to clean the surface of the boiler.
• Do not place flammable objects on or near the boiler.
• Do not place flammable materials in the boiler installation compartment (e.g. wood, paper, petroleum, gas oil).
Wood is an extremely heterogeneous fuel for type, moisture content, shape and size. Boiler heating efficiency depends
on the type of wood used and its moisture content, as well as the method of loading and size of the fuel. Excellent quality
woods are oak, ash, beech, maple and fruit trees except cherry; chestnut and birch are good quality; lime, poplar and
willow are of adequate quality. Resiniferous woods are generally mediocre fuels. The higher the moisture-content, the
lower the heating power. The use of fuels that are not dry causes losses of efficiency. Use logs dried outdoors and in
the natural state (stored for 2 years with max. moisture content 20%).
plosion.
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 switch to ON.
• Open the top door. Place some paper and kindling on the burner plate.
• Light the fuel and add some slightly larger pieces of wood.
• Close the door and wait for a first bed of embers to form.
• Open the top door slowly to allow the fan to suck the smoke accumulated in the firewood holder.
• Spread the embers evenly on the burner plate, using a poker.
• Load wood when the bed of embers has formed on the main stone.
Loading wood
• Proceed with loading wood which must be 50 cm long for models FG30 and FG40, and approx. 70 cm for model
FG50.
• Since regular falling of the wood is essential for good combustion, make sure that the length of the pieces of wood
introduced, their shape and method of loading do not hinder it. The pieces must be arranged lengthwise and horizontally. No pieces must be inclined or placed sideways.
• Consume the wood as much as possible before loading more.
• New loading can be carried out when the bed of embers in the holder is approx. 5 cm deep.
• Open the top loading door slowly.
• Arrange the new load of wood in the same way as previously described.
- Pieces that are too long do not fall regularly, causing empty spaces in the wood holder, with the formation of
B
unburnt wood areas.
- 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 avoid puffs and the creation of smoke.
- Never open the bottom door during operation.
- During loading avoid keeping the top door open for long periods.
- In case of operation with reduced performance, low temperature distilled gases can form, with risk of poisoning if breathed.
- If dense smoke can be seen, do not breathe it.
- Make sure the installation room is well-ventilated.
- Clean the boiler and gas exhaust 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.
Shutdown for long periods
To put the boiler out of service for long periods (e.g. at the end of the cold season), carefully clean the boiler to prevent
corrosion.
To avoid damage caused by freezing during long idle periods in winter, it is advisable to drain all water from

Routine maintenance
Soot and ash on the inside walls of the boiler and on the refractory bricks reduces the transfer of heat. However, during
the operation of a boiler with wood gasification less ash is produced than during heating with conventional boilers.
Remove the ash from the combustion chamber every 1-2 days, and in any case before it is full, so as to leave sufficient
space for combustion.
If the ash is still hot, use protective gloves.
B
Carry out thorough cleaning at least once a week:
• Open the loading door and brush the combustion residuals in the ash compartment through the opening between
• Clean the inside walls of the combustion chamber with a brush
• Remove the loose soot and ash from the combustion chamber.
• Check perfect door closure seal. Also make sure there is no tar or condensate dripping from the smokebox.
