3.3.
Installation of the fireplace
3.3.1. Positioning and connection
Put the fireplace at proper height. Make
sure that it is stable and level and that
the side panels are perpendicular to the
bottom plate. Put the fireplace far enough
from the walls, so that minimum 5 cm of
free air passage remains between the
back of the fireplace and the wall after
adding the necessary insulation.
Make an airtight connection between fire-
place and chimney, according to good
practice.
Before further installation of the fireplace,
check for sufficient draft in the chimney
and for proper connection between the
smoke duct and the appliance.
For that purpose, you can light a small
intense fire with paper and small dry kin-
dle. In case of a brick smoke duct, wait
until the duct is dry enough.
3.3.2. Mounting
Start with the masonry round the base of
the fireplace. In that masonry, the air
supply grids (optional) will be installed. Minimum air supply opening is 250 cm².
The grids may be installed on all sides.
It is important that air flows freely into the convection chamber. If you use an air
vent (to convey outside air into the convection chamber), remember to build in the
adjustment knob.
It is recommended to cover the inner side of the convection chamber with extra re-
flecting insulation material. That prevents loss of heat radiation to outside walls or
adjacent rooms, as well as deterioration of any inside wall insulation.
Make sure that the doors of the hearth move freely over the plate in front of the
fireplace.
Continue building the chimney up to the smoke dome. Assure a gap of at least 2
mm between the fireplace and the masonry to allow for dilatation of the fireplace. If
necessary, use heat-resistant strips.
Upper structure support
The masonry over the fireplace must not rest on the fireplace. That is why a support
is used. Between the steel support and the smoke dome, you must leave a free
space of at least 3 mm. That will prevent tensions in the material that might tear the
upper structure. The steel support may rest on the side structure or be attached to
the wall by means of threaded rods.
