5. Before Installing a new fireplace
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
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 should 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
Attention! It is recommended to use a qualified
professional when installing a new fireplace.
Air supply (=mm AIR)
A set for fresh air supply is available as an 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 constructions, we strongly rec-

ommend the product is designed and prepared for direct
supply of outside air. In older houses also, the use of
fresh air supply set is also recommended. Insufficient air
supply can cause poor draught and thereby low com-
bustion efficiency and the problems this entails: soot
stains on the glass, inefficient utilisation of the wood and
a soot deposits in the chimney.
Distance illustration (FIG 1)
*The illustration indicates the approximate centre height
of the recess for the flue. Consider possible inclination
of the flue prior to making perforating the chimney.
Distortions in floors and walls may also influence the
height, dry stack therefore the fireplace for accurate
height and positioning of the flue/chimney connection. If
a fresh air supply set (accessory) is connected through
the floor, mark where the hole should be.
Attention! Since the inner core is composed of
many layers the connection height may vary by up
to a few centimeters from installation to installation.
Safety distances (FIG 2)
Ensure that the safety distances are complied with.
IMPORTANT! Drying Process
The fireplace contains a lot of moisture when it is new
and no fire has been made before. This moisture must
be dried out before the fireplace can withstand the
combustion rate given below.
To extract the moisture, follow this procedure:
1. Ensure that the air vent control just below the door is
2. Ensure that the damper is in ignition mode.
3. Make a small fire with 1-2 kg of kindling wood
4. Set the damper in operating mode, once the flames
Attention! Let the air vent and damper remain open
until the fire is burnt out.
This procedure is repeated twice more, with a 24 hrs
gap between each time.
Attention! Failure to follow the guidelines for drying
can cause the elements to crack.
