controlled by gas temperature, outside temperature, air
supply as well as the height and inner diameter of the
chimney. The diameter of the chimney should never
be less than that of the flue/chimney collar.
At nominal
effect there should be a negative pressure of 12 to 25
Pascal.
The draft increases when:
•
The chimney becomes warmer than the outside air
•
The active length of the chimney over the hearth
increases
•
Good air supply to the combustion
It can be difficult to obtain the right draught conditions
in case the chimney is too large relative to the fireplace,
as the chimney does not heat up well enough
. In
such cases you may want to contact professional for
evaluation of possible measures. Draught that is too
strong can be controlled with a damper. If necessary,
contact a chimney sweeper. The product is type
tested and should be connected to a chimney that is
dimensioned for the smoke gas temperature indicated
in the CE declaration. When necessary, contact a
professional in advance
Air Supply FIG Ronda Air
A set for fresh air supply is available as accessory.
This will ensure that the air supply to the combustion
chamber is less affected by ventilation systems,
kitchen fans and other factors which can create a
down-draught in the room. In all new construction, we
strongly recommend that it is designed and prepared for
direct supply of outside air. In older houses, the use of
fresh air supply set is also recommended
.
Insufficient
air supply can cause down-draught and thereby low
combustion efficiency and the problems that this
entails: soot stains on the glass, inefficient use of the
wood and a soot deposits in the chimney.
Floor plate
A fireproof floor plate must be put in front of the fireplace
if the floor is of a combustible material.
Dimensional drawing
The illustrations indicate the approximate centre height
of the hole for the flue. Distortions in floors and walls
may influence the dimensions. Dry stack the fireplace
without glue for accurate height and positioning of the
flue/chimney connection.
3. Technical Information
The inserts from Nordpeis have secondary combustion
and are clean burning. The combustion takes place in
two phases: first the wood burns and then the gases
from the fumes are lit by the hot air. This ensures that
these new inserts have minimal emissions of soot
particles and unburnt gases (such as CO) and are
thus better for the environment. Clean burning inserts
require a small amount of wood in order to obtain a
good heat output. Use exclusively clean and dry wood.
Painting
Once the fireplace has been assembled, the joints
been filled and the glue dried, it is ready to be painted.
Use only breathable paint (acrylic) suited for concrete.
In order to add some structure to the surface, if so is
required, add some poweder glue (included) to the
paint.
Marble/granite
Clean the plates with mild soapy water and remove any
residue of spilled glue.
Never use acid/abrasive materials, as this will damage
the surface and polishing.
It is important to use detergent/sealant that is approved
for marble for cleaning and sealing.
Scratches in dark marble can be coloured with a pencil.
A professional stone centre can help you with different
products for surface treatment of the stone
For your own safety, comply with the assembly
instructions. All safety distances are minimum distances.
Installation of the insert must comply with the rules and
regulations of the country where installed. Nordpeis AS
is not responsible for wrongly assembled inserts.
We accept no liability for typographical errors and
changes.

2. Before Installing a new fireplace
All our products are tested according to the latest
European requirements and also
to the Norwegian
standard NS 3058 and NS 3059,
which include particle
tests. However, several European countries have local
regulations for installation of fireplaces, which change
regularly. It is the responsibility of the client that these
regulations are complied with in the country/region
where the fireplace is installed. Nordpeis AS is not
responsible for incorrect installation.
Important to check
(please note that this list is not exhaustive):
•
distance from firebox to combustible/flammable
materials
•
insulation materials/requirements between
fireplace surround and back wall
•
size of floor plates in front of fireplace if required
•
flue connection between firebox and chimney
•
insulation requirements if flue passes through a
flammable wall
Chimney Draft
Compared to older models, the clean burning fireplaces
of today put significantly higher demands on the
chimney. Even the best fireplace will not work properly
if the chimney does not have the right dimensions or
is not in good working order. The draught is mainly
