Low Emission Fire Lighting; Normal Operation; Electrical Power Supply Failure - Nordica DSA Gebrauchsanleitung

Therefore, it is extremely relevant to take these easy steps during the lighting:
1. Make sure that a strong air change is assured in the room where the appliance is installed.
2. During the first starts, do not load excessively the combustion chamber (about half the quantity indicated in the instructions manual)
and keep the product continuously ON for at least 6-10 hours with the registers less open than the value indicated in the instructions
manual.
3. Repeat this operation for at least 4-5 or more times, according to your possibilities.
4. Then load more and more fuel (following in any case the provisions contained in the installation booklet concerning maximum load)
and, if possible, keep the lighting periods long avoiding, at least in this initial phase, short ON/OFF cycles.
5. During the first starts, no object should be leaned on the appliance and in detail on enamelled surfaces. Enamelled surfaces must
not be touched during heating.
6. Once the «break-in» has been completed, it is possible to use the product as the motor of a car, avoiding abrupt heating with
excessive loads.
After testing the proper working of the appliance, some days from the installation, it is possible to proceed with the construction
of its aesthetic covering.
WARNING: During the surround building operations it must kept in mind possible and subsequent electrical installed parts maintenance
(Fans, temperature probe, etc) and with hydraulic systems all parts connected to the thermo-fireplace.

LOW EMISSION fire lighting

Smokeless combustion is a way of lighting a fire able to significantly reduce the emission of harmful substances. The wood burns gradually
from the top downwards, so combustion is slower and more controlled. Burnt gases pass through the high temperatures of the flame and
therefore burn almost completely. A load will last from 6 to 8 hours.
Place the logs in the hearth a certain distance apart as shown in the
smallest at the top, or vertically in the case of tall narrow combustion chambers. Place the fire starter module on top of the pile, arranging
the first logs in the module at right angles to the pile of wood.
Fire STARTER MODULE. This fire starter module replaces a paper or cardboard starter. Prepare four logs, 20 cm long with a cross section
of 3 cm by 3 cm Picture 13 at page
impregnated wood fibre for example) in the middle. The fire can be lit with a match. If you want, you can use thinner pieces of wood. In this
case, you will need a larger quantity. Keep the flue gas exhaust valve and combustion air regulator open.
After lighting the fire, leave the combustion air regulator open in the position shown:
IMPORTANT:
• do not add further wood between one complete load and the next;
• do not suffocate the fire by closing the air intakes;
• regular cleaning by a chimney sweep reduces fine particle emissions.

8. NORMAL OPERATION

After having positioned the registers correctly, insert the indicated hourly wood load avoiding overloads that cause anomalous stresses
and deformations. You should always use the product with the door closed in order to avoid damages due to overheating (forge
effect). The inobservance of this rule makes the warranty expire.
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.
With the registers located on the front of the device, it is possible to adjust the heat emission of the same. They have 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. Too much fuel and too much air for the combustion may cause overheating and then damage the
product. You should always use the appliance with the door closed in order to avoid damages due to overheating (forge effect).
The adjustment of the registers necessary to reach the rated calorific yield with a depression at the stack of 17-20 Pa (1,7-2 mm of column
of water) is the following one: see chap. TECHNICAL DESCRIPTION. The appliance works as an intermittent operating appliance.
In the event that the water temperature exceeds the tripping temperature of the safety devices, immediately suspend the feeding
of wood, and make sure that the water temperature and the flame decrease, eliminating the causes of the overheating (if necessary
by closing the air register).
If the water system is connected in the thermo-fireplace, the hot water tap can be opened to speed up the cooling of the appliance.
Besides the adjustment of the air for the combustion, the intensity of the combustion and consequently the thermal performance of the
device 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 device is not properly adjusted or the wood is too wet; if instead the smoke is gray or black, it signals that the
combustion is not complete (it is necessary a greater quantity of secondary air).

ELECTRICAL POWER SUPPLY FAILURE

In the event of an unexpected electrical power supply failure during normal system operation, it will be necessary to carry out these simple
manoeuvres to prevent the water in the boiler starting to boil as a consequence of the lack of pump operation.
• Close completely the primary and secondary air registers in order to smother the flame as much as possible.
• Close the smokes register, if existing, to limit further coming of combustive air through possible cracks.
