3 CHIMNEY FLUE
3.1 INTRODUCTION
This chapter about the Chimney Flue has been drawn up in cooperation with Assocosma (www.assocosma.org) and is based on
European Standards (EN 15287 - EN 13384 - EN 1856 - EN 1443) and UNI 10683:2012.
It provides instructions for a good and correct execution of the chimney flue but it does not absolutely replace the current stan-
dards which the qualified manufacturer/installer should comply with.

• The chimney flue must be sealed from fumes.
• It must have a vertical run without narrowing. It must be realized with fume and condensation resistant materials with ther-
mal insulation and able to last against usual mechanical stresses.
It must be insulated to avoid condensation and to reduce fume cooling effects.
• The stove must be spaced out from fuels or flammable materials with an air gap or with insulating materials. Check the distan-
ce with the chimney manufacturer.
• The chimney entrance must be placed in the same room where the appliance is installed or otherwise in the adjacent room and it
must be provided with a solid and condensation collection chamber under the entrance, accessible through the sealed metal gate.
• Auxiliary exhaust fans cannot be installed neither along the chimney nor on the chimney pot.
• The inner section of the chimney flue can be round (the best one) or square and the jointed sides must have a minimum radius
of 20 mm.
• The section dimension must be:
•minimun Ø100 mm
•recommended max Ø180 mm
• Made the efficiency of the chimney flue overhauled by an expert stove-repairer and if necessary cover the chimney flue with
materials in compliance with current regulations.
• The flue system must be placed on the roof.
• The chimney flue must be provided CE in accordance with EN 1443 regulation. Please find attached an example of label:

3.4 HEIGHTDEPRESSION
The depression (draught) of a chimney flue depends also on its height. Check the depression with the values provided at FEATU-
RES a pag. 43. Minimum height 3,5 meters.
3.5 MAINTENANCE
• The fumes extraction pipes (fumes conduit + chimney flue + chimney pot) must always be cleaned, scrubbed and checked
by an expert stove-repairer, in compliance with current regulations, with the instructions of the stove-manufacturer and the
directives of your insurance company.
• In case of doubts, please follow the most restrictive regulations.
• Have your chimney flue and chimney pot checked and cleaned by an expert chimney sweep at least once a week.The chimney
sweep has to release a written declaration about the security of the system.
• Not cleaning compromise safety.
3.6 CHIMNEY POT
Fig. 4 - Anti-wind chimney pots
The chimney pot is important for the correct running of the heating appliance:
• We recommend using an anti-wind chimney pot, see Fig. 4.
• The hole width for fumes exhaust must be the double of the chimney flue width and fitted in a way that the fume exhaust is
assured also in case of wind.
• It should prevent the infiltration of rain, snow and animals.
• The outlet height in the atmosphere must be away from the reflux area caused by the roof structure or by obstacles laying
nearby (see Fig. 2).

• External chimney flue entirely made up of insulated stainless steel pipes, i.e. with double wall of minimum Ø100/120 mm: all
must be firmly attached to the wall. For chimney against wind effects please (see Fig. 4).
• Ducting system through T-unions which enables an easy cleaning without disassembling the pipes.
We recommend to check with your chimney flue manufacturer the safety distances which must be respected
and the type of insulating material. The aforesaid regulations are valid also for holes made on the wall (EN
13501 - EN 13063 - EN 1856 - EN 1806 - EN 15827).
4 COMBUSTION AIR
4.1 EXTERNAL AIR INLET SATURNO
It is mandatory to provide an adequate external air inlet that supplies the combustion air required for the product to work pro-
perly. The flow of air between the outside and the installation room may be direct, through an inlet in an external wall of the
room (preferable solution see Figure 9 a), or indirect, via air intake from adjoining rooms and connecting permanently with the
installation room (see Figure 9 b). Adjoining areas may not include sleeping areas, bathrooms, garages or general areas with a
fire hazard. During installation it is required to check the minimum clearances required to draw air from outside. Take into account
the presence of doors and windows that may interfere with the proper flow of air to the stove (see diagram below).The air intake
must have a minimum total net area of 80 cm2: the surface must be increased accordingly if other active generators (for example:
electric fan for stale air extraction, kitchen hood, other stoves, etc.), which may cause negative pressure in the room, are installed.
Make sure that, with all appliances on, the pressure drop between the room and the outside does not exceed the value of 4 Pa
(also for Oyster appliances if the combustion air has not been suitably ducted outside). If required, increase the intake section of
the air inlet, which must be made at floor level and always protected with a bird-proof outer protection grid and in such a way that
it cannot be obstructed by any object.

It is possible to connect the air required for combustion directly to the outside air inlet, with a pipe of at least Ø50mm, with maxi-
mum length of 3 linear metres; each pipe bend shall be considered equivalent to a linear metre.To attach the pipe see the rear of the
stove. For stoves installed in studio flats, bedrooms and bathrooms (where allowed), it is mandatory to connect the combustion air
outside. Specifically for sealed stoves the connection must be sealed in order not to compromise the overall sealing of the system.

7 TYPE OF FASTENING SATURNO
7.1 HOW TO FASTEN THE INSERT
It is mandatory to anchor the product to a surface since, during annual maintenance operations by the authorised technician, or
when the fuel is loaded, the combustion chamber may be extracted from its seat with the aid of two retractable guides. The pro-
duct can be anchored to an existing surface (which must have certain characteristics) or it can be fastened to the optional support.
Attention! The support surface of the insert must be completely flat.
7.2 FASTENING TO AN EXISTING SURFACE  SUGGESTED CHARACTERISTICS
Installation data
The surface where the fixed part of the insert will be fastened must be in R250 kg/cm2 concrete, if the support is made of poor
material, it is advisable to use a suitable slab for fastening.

For installation on an existing surface, ensure there is a thickness of at least 17 mm between the fixed wall“A” and
the existing surface “U”, and fix the insert and surface using plugs “t” as shown on the previous page. Make sure
everything is level.
7.3 FASTENING TO THE HORIZONTAL SUPPORT
Place the base in the desired position (after mounting it as explained in the instructions attached to the accessory) and adjust the
height by using the feet (from a min. of 500 mm to a max. of 650 mm).
Make sure there is a power socket behind the pedestal so that the plug is accessible after the unit has been installed. Connect the
smoke outlet and make the air inlets.
It is mandatory to fasten the support to the floor with anchor bolts and 8 mm diameter screws that will ensure stability of the
product. Take the sliding base and fasten it with the support bracket. The support is already provided with bracket “P” for other
types of product. Do not mount the bracket“P”supplied in the support pack but use the one provided with the insert.

Take the movable part off the insert and connect the fixed part“A”to the support“S”with the bracket“T”and screws“k”provided.
8 MINIMUM DISTANCES SATURNO
It is recommended to install the stove detached from any walls and/or furniture, with a minimum clearance to allow effective
aeration of the appliance and a good distribution of heat in the room. Comply with the distances from flammable or heat-sensitive
objects (sofas, furniture, wood panelling, etc.) as specified below. The frontal distance from flammable materials must be at least
as specified in the product’s technical data table.
If there are particularly delicate objects such as furniture, curtains or sofas, increase the stove distance accordingly.
If the floor is made of wood, it is recommended to fit a floor protection sheet in compliance with the standards
in force in the country of installation.
