FUEL
Permitted fuel
The device is suitable for burning firewood.
Only small amounts of the following materials may be used for igniting purposes: bark,
wood chippings, brushwood, wood shavings, sawdust and paper. When these types of fuel
are set alight, large amounts of emissions and ash are discharged, with little heat being
generated.
Wood
The water content of firewood should be less than 20% of its dry weight.
Firewood should also be max. 1/3m long and chopped into small pieces. In this way, the
pieces of wood catch fire quickly and generate a higher heat output than if the same
amount of wood were used in larger pieces. Spruce, pine and alder can be stored outdoors
for 2 years, whilst hardwood
can be stored for 3 years
(under cover!).
The following table shows
the impact of the water
content of wood on its heat
value:
Refuelling on to a low fire bed
If there is insufficient burning material in the firebed to light a new fuel charge, excessive
smoke emission can occur. Refuelling must be carried out onto a sufficient quantity of
glowing embers and ash that the new fuel charge will ignite in a reasonable period. If there
are too few embers in the fire bed add suitable kindling to prevent excess smoke.
Unauthorised fuel
Surface-treated wood (veneered, varnished, water- proof coating, etc.), damp wood,
chipboard, flammable liquids, any type of waste (packaging waste), plastics, newspapers,
rubber, leather, fabrics, etc. Burning these kinds of materials pollutes the environment very

badly. Furthermore, it may cause damage to the device and chimney.
Burning charcoal is not permitted. The device has not been verified for use with this kind of
fuel and, as such, it may cause damage to the device and is not covered by the guarantee.
PLEASE NOTE If unauthorized and low-quality fuels are used, we reserve the right to
withdraw the guarantee and warranty claims!

Installation in a stove recess
It is only permitted to install the stove in a recess, built using non-flammable components
(e.g. in an inoperative, open fireplace) and with a flue pipe connection which leads upwards
into the chimney, if there is a minimum distance of at least 5cm from the sides.
Floor protection
If the floor is made from flammable material (floors made from wood, synthetic materials,
carpets, …), a superimposed hearth made from toughened glass, or any other non-
flammable material, should be used.
This base must have the following minimum dimensions, with the opening of the
combustion chamber as the starting point:
•Front 225mm
•Side 150mm

(please see accessory component 7 provided) install
after the final location for the stove has been chosen.
Chimney
It must be ensured that any new or existing
chimneys are suitable and ready for use before
using the stove, or before entering it into service.
Please ensure that the chimney is not blocked if
the device is going to be lit after it has not been used for a long time.

Sirius Operating Manual

Room-sealed operation
Schiedel recommends using the Sirius stoves together with our tested and approved
Permeter Smooth Air System, which has been specifically designed for use with
room sealed appliances.
As modern or refurbished houses have a highly dense construction, it often means that
there is not enough interior air for combustion.
The SIRIUS stove has been certified as a room-sealed stove as per the DIBt (Deutschen
Institutes für Bautechnik, German Institute for Structural Engineering) eligibility criteria.
As such, the stove can be used, by and large, regardless of the air and pressure rations in
the room where it has been installed.
It is safe to use these kinds of room-sealed stoves if the building has a controlled ventilation
system as they are characterised by their largely compact design and self-closing doors.
If the structural conditions mean that room-sealed operation is impossible, it is also possible
for the SIRIUS stove to draw the combustion air from the room where it has been installed
(non-room-sealed operation).
In this case, the installer should ensure that the air supply in the room where the device has
been installed is sufficient.
Connection methods
1.) On standard installations using Permeter Smooth Air, the combustion air is brought
directly into the stove through the outer wall of the Permeter Smooth Air System
2.) Combustion air comes from the rear or from below. The connecting element is 100 mm
in diameter. The air pipe used by the installer should be airtight.
3.) Combustion air comes from the room where the
device has been installed (not recommended by
SCHIEDEL)
No separate air supply connection necessary,
combustion air is extracted from the room where the
device has been installed via the bottom of the
device – open windows regularly, this is mandatory,
especially for extremely impermeable houses

OPERATION
Accessories provided
A hook is provided for the revolving grate, as well as a protective glove to open the heating
door (please refer to page 4).
Heating door lock
The device has a self-closing door. Simply pull on the door handle to open the heating door.
Setting for the combustion air
For optimal combustion, a certain amount of wood requires a certain amount of oxygen. If
the amount of air supplied to the wood is smaller than that need for a clean and efficient
combustion process, the device will generate less energy (device protected from
overheating as far as possible) - the unused “wood gas” escapes through the chimney; the
result: the device is less effective and the environmental footprint is higher.
PLEASE NOTE It is strictly necessary to observe the recommended fuel quantities and air
settings!
The primary air entering the combustion chamber from below via the grate is responsible
for performance, as it generates most of the heat that leads to “wood gasification”. This
wood gas is burnt in a clean and efficient manner thanks to pre-heated secondary air.
The secondary air comes from above and flows along the combustion chamber door (or
window) and over the fuel in the combustion chamber. An accurate mixture of wood gas
and hot secondary air creates an optimal combustion process - and in turn excellent use of
fuel. Nature will thank us for it!
Setting for the Air Supply Lever to prevent flow of combustion air
The supply of the primary and secondary air required for
combustion is regulated using the lever to manage flow of
combustion air.
This determines the burning rate and, as such, the amount of
heat output by the device.

Sirius Operating Manual
Sirius Operating Manual Page | 20
Device set to “0”
(only permitted in areas not covered by DEFRA restrictions for use on wood burning
appliances).
When set to “0“, the air feed is closed, and no combustion air is supplied = this should be
the setting if the device is not going to be used for long periods (e.g. in summer).
Heat setting “1“
When set to “1“, primary and secondary air is supplied in a ratio optimal for a clean
combustion process = setting to operate the device at nominal capacity.
Heat setting “2“
A large amount of combustion air is needed in the igniting phase and the lever should be
pushed all the way to the right to setting “2” = maximum supply of primary and secondary
air.
PLEASE NOTE Setting “2” should only be selected for igniting purposes!
Dampers left open
Operation with the air control or appliance dampers open can cause excess smoke. The
appliance must not be operated with air controls, appliance dampers or door left open
except as directed in the instructions.
In order for the stove to comply with the DEFRA exempt conditions, a DEFRA kit
must be installed, as per the instructions below:
