CAREFUL!
For flue duct configurations 2 to 4 (see
paragraphe 8.1), we recommend to remove the
the ceiling plates permanentl.

Placing and finishing the surround
Protection against high temperatures
FIRE HAZARD!
The gas fire can be delivered with or without
convection hood. In all cases it is important that
there is sufficient ventilation. The temperature on
the top of the appliance is very high. Under no
circumstances may the surround be insulated.
Always follow the installation instructions.
See: Installation Instructions paragraph 2.3).
Connecting without convection hood
Place the grids or other openings in the surround
for the ventilation of a fireplace without
convection hood. The grids or opening protect
the surround against high temperatures.
Ventilation grids must have a dimension of at
least 350 cm2 per side. Grids can be replaced by
opening with an intake of at least 350 cm2 and
an outflow of at least 350 cm2.
TIP:
Deviating connections can be submitted to
Kalfire for written approval.

(2) Grid for exit of convection air (two openings of at
least 175 cm2)
Connecting with convection hood
The convection hood is mounted on the
appliance in the factory and so cannot be
installed afterwards. The convection hood
ensures a delivery of controlled heat in the
room where the gas fire has been installed. This
optimises the heat output of the appliance.
Mount two aluminium ducts of (Ø150 mm) to the
convection hood and connect these to the
ventilation openings or grids mounted on the
convection hood. The total cross-section of the
outlets must be a minimum of 350 cm2.
CAREFUL!
Sealing the fireplace is at your own risk, damage
to the varnish caused by sealing falls outside of
the factory warranty.

TIP!
Ensure that the right-hand ventilation inlet can
be opened so that you can access the various
connections located on the right-hand side of
the E-box if necessary (see paragraph 5.3)
The air gap
The fireplace's electronics are cooled by means
of a fan that comes on when the temperature
exceeds 35 degrees. The air is drawn in through a
7mm air gap to be provided at the front.
WARNING!
Make sure that no construction debris can fall
into the E-box during installation and finishing of
the fireplace. For this, temporarily cover the air
gap. (e.g. with a piece of cardboard).
