Chimney stove ESTER

10. NORMAL OPERATION

For safety reasons the door of the appliances with constructive system 1, must be opened only for the
loading of the fuel or for removing the ashes, while during the operation and the rest, the door of the hearth
must remain closed.
The appliances with constructive system 2 must be connected to their own flue. The operating with open
door is allowed under supervision.
IMPORTANT: For safety reasons the door of the hearth can be opened only for the loading of the
fuel. The hearth door must always remain closed during operation or rest.
The nominal power of the appliance is of kW 6.5. This power will be reached with a minimum depression in
the chimney of 13 Pascal (=1.3 mm of water column).
With the control located on the front of the appliance (Picture 1 A), it is possible to adjust the heat emission
of the same. This is to be opened according to the calorific need. The best combustion (with minimum
emissions) is reached when, by loading the wood, most part of the air for combustion flows through the
secondary air register.
Never overload the appliance (see the hourly wood load in the table here below). Too much fuel and
too much air for the combustion may cause overheating and then damage the stove.
You should always use the ESTER with the door closed in order to avoid damages due to overheating
(forge effect).
The inobservance of this rule makes the warranty expire.

The ESTER is an appliance with intermittent operation.
Besides the adjustment of air for combustion, the intensity of the combustion and consequently the thermal
performance of your appliance is influenced by the stack. A good draught of the stack requires a stricter
adjustment of air for combustion, while a poor draught requires a more precise adjustment of air for
combustion.
To verify the good combustion, check whether the smoke coming out from the stack is transparent.
If it is white, it means that the appliance is not properly adjusted or the wood is too wet; if instead the
smoke is grey or black, it signals that the combustion is not complete (it is necessary a greater quantity of
secondary air.

11. OPERATION IN TRANSITION PERIODS

During transition periods when the external temperatures are higher, if there is a sudden increase of
temperature it can happen that the combustion gases inside the flue cannot be completely sucked up.
The exhaust gases do not come out completely (intense smell of gas). In this case, shake the grating more
frequently and increase the air for the combustion. Then, load a reduced quantity of fuel in order to permit a
rapid burning (growing up of the flames) and the stabilization of the draught.
Then, check that all openings for the cleaning and the connections to the stack are air-tight.

12. OVEN OPERATION (if present)

After shaking the grate, load some fuel. Thanks to the air flow for the combustion, the temperature of the
oven may become remarkably affected. A good draught of the chimney and channels well cleaned for the
