DISTANCE TO ENSURE FIRE SAFETY
The requirements for fire safety are obligatory:
·
Minimum distance at the side and at the back of the fireplace must be 40 cm.
·
Minimum distance in front of the fireplace must be 80 cm.
·
To use insulation and fire-safe stand for the fireplace, if the floor is inflammable. The stand must be 20 cm wide at the side and 40 cm in front.
·
Don't put any inflammable objects closer than 0,5 m from the fireplace
·
When connecting the fireplace with the chimney, density should be guaranteed, as well as strength of attachment and prevention of the danger
of fire.
INSTALLATION TO A CHIMNEY
The flue gases from the fireplace are lead out and discharged into a chimney by means of a metal chimney stack (pipe). When installing, density and
safety against pulling down shall be guaranteed.
It is not allowed to use a common stack. The chimney must be independent and there must be no other appliances discharged and included to it, even
such that aren't used.
In multifamily residential buildings there can be collective chimneys, designed and built with a special construction design, which is intended to be used
by more than one appliance. In such case, you must know with certainty that the condition of this chimney is good and no flue gases can go out through the
chimney in an unregulated way into residential and building premises. The chimney must be absolutely dense and well insulated.
The presence of any temporary, spare, constant etc. openings is not allowed, except a dense and tightly closed opening for cleaning, located sufficiently
… (low
?
)under the discharge of the fireplace and suitable for cleaning.
INCOMING EXTERNAL AIR
The fireplace must be provided with air supply, necessary to guarantee a normal combustion process and clean ambient atmosphere.
It is obligatory for this air to be taken from the outside of the building and in the shortest possible way is connected with PVC pipe
ø
40 mm lead out in the
back wall of the fireplace. The entrance hole must be protected in a proper way against clogging, infusion of water or any objects. The air must be able to pass
unhindered through the air pipe outside the fireplace.
In the room where the fireplace is installed no presence of any system which sucks air from the premise is allowed. Such system (fan for discharging air,
absorber etc.) could cause dilution of the air in the room. As a result, returning flue gases from the burning fireplace into the premise is possible, and it is not
only undesired but also harmful and dangerous for your health. Because of non-observance of the above mentioned, there are such cases with ordinary
fireplaces on wood. The pellet fireplaces are better protected, namely because of the availability of an ID fan. Nevertheless:
The compliance with the instructions is obligatory to ensure your safety.
CONNECTION OF THE FIREPLACE TO A WATER HEATING SYSTEM (WHS)
Water heating system must be built up and connected to the fireplace – WHS, radiators etc. with installed heat power up to 16 kW.
The fireplace functions only together with a built-up and connected water heating system, which is built by a specialized company when observing all
local, national and European norms assuring functionality, comfort and aesthetics.
INFORMATION AND INSTRUCTIONS
The pump is electrically connected and controlled by the controller. It is fitted only mechanically – the threaded connections have no gaskets. Their
sealing with suitable materials is done during installation by the installation company.
A filter with two spherical taps is fitted to the inlet of the pump outside at the back of the fireplace. The returning cooling water must enter the filter from
the radiators.
The built WHS must have a possibility for the heat-transfer medium (water) to drain from the system in its lower part.
WHS can be closed, with a closed membrane expansion vessel.
The fitting of a safety valve is obligatory which shall not allow an increase of the pressure in the installation (and the fireplace) above 2 bars (0,2)M Pa.
WHS can be open, with an open expansion vessel.
It is not allowed to fit a stopcock between the outlet of the fireplace and the inlet for the hot water of the WHS.
The connection between the chimney and the expansion vessel is direct, without any stop fittings. When building WHS, automatic deaeration (self-
deaeration) of the system must be ensured.
During operation full switching off of all heaters is not provided and is not allowed in any way.
Characteristics and settings of pump GRUNDFOS ALFA 2L:
The flow and the head of the pump can be changed by pressing the button.
PP1- characteristic of the lowest proportional pressure.
The head is reduced when the heat energy decreases and it increases when the heat energy increases.
PP2 –characteristic of the highest proportional pressure.
The head decreases when the heat energy decreases and it increases when the heat energy increases.
CP1 – characteristic of the lowest constant pressure.
The head is kept constant regardless of the energy heat consumption.
CP2 – characteristic of the highest constant pressure.
The head is kept constant but higher.
Speed III – (factory default)
The pump runs at a constant high speed, set to operate at the maximum characteristic under all operation conditions.
It is most suitable also on initial venting.
Speed II
– the pump runs at a constant average speed.
Speed I
– the pump runs at a constant low speed.
From the available characteristics the most suitable for the built installation can be selected. It matters the presence of thermostatic valves, underfloor
heating, etc.
