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 fire-
place and the wall after add-
ing the necessary insulation.
Make an airtight connection
between fireplace and chim-
ney, according to good prac-
tice.
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 kindle.
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. Mini-
mum 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 reflecting insulation material. That prevents loss of heat radia-
tion 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.
