The furnace should be placed as centrally as possible
to achieve an even distribution of heat. Fire safety
regulations must also be taken into consideration when
planning the location.
The space required for installation consists of the
space taken up by the fireplace or stove itself as well
as the safety distances and space needed for normal
use and maintenance tasks.
The person tending the fire needs a space of at least
one metre in both width and depth in front of the
furnace. For the minimum safety distances of individual
models, refer to “Technical data”.
Your local fire authorities can provide more detailed
information on fire safety regulations.
Smoke flue
The draught depends on the difference in density
between the gas in the chimney and the outside air, as
well as the height of the chimney. The hotter the gases
in the chimney, the bigger the density difference
between the outside air and the chimney gases.
Landscape and weather conditions also influence the
draught of the smoke flue. If the building is located next
to high trees or a hill, the chimney must also be high. It
may be difficult to create a good draught during low
pressure due to the small density difference.
If a fireplace or stove is replaced with a new one, or
an open fireplace is equipped with a fireplace insert
with doors, make sure that the smoke flue can be used
for the new purpose.
If the furnace is altered to use a different fuel (e.g.,
an oil stove is converted into a furnace using solid fuel),
contact a chimneysweep to determine the suitability
and condition of the smoke flue.
Chimney fires, even extinguished ones, must always
be reported to the regional fire brigade control.
Installation location
The fireplace or iron stove is placed on a platform made
of non-flammable material. Alternatively, the platform
can be shielded with non-flammable material, such as
a metal sheet.
The platform shielding must be at least 50 mm wider
than the furnace at the back and sides and 400 mm in
front.
The combustion gases are removed through a Harvia
modular smoke pipe or a smoke flue made of bricks
with a minimum size of 140 x 140 mm. In the case of
iron stoves, Harvia chimneys are also a viable option.
When using a Harvia modular smoke pipe, the fireplace
can be placed in the most practical location.
The fireplace can be connected to the smoke pipe
either from the back or top. The first stage in the smoke
pipe assembly is the installation of the adjustment part.
For more detailed installation instructions, see the
Instructions for installation of Harvia modular smoke
pipes.
Follow the manufacturer’s instructions for safety
distances and the installation of pre-manufactured
flues.
Moving the flue connecting piece to the top
or side
The smoke flue can be connected to the top or back of
Harvia’s fireplaces, and to the top, back or sides of
Harvia’s iron stoves. The fireplaces and stoves
supplied directly from the factory are equipped with a
straight flue pipe and a connection in the back.
If required, exchange the flue connecting piece in the
back of the furnace and the protective cover on the top
or side of it with one another before starting work on
the actual flue connection.
Detach the protective cover from the outer casing by
cutting the clamps. This can be done with, for example,
a hacksaw blade. Remove the flue connecting piece
located in the back opening and the screwed-on cover
protecting the flue outlet.
Join the flue connecting piece to the opening located
on the top of fireplaces, or on the top or side of iron
stoves. Attach the protective cover to the opening in
the back. Ensure that the flanges fit tightly in place and
that the screws have been properly tightened.
The hole in the rear of the outer casing must be
covered with a plate (ca. 200 x 200 mm) if the wall
facing the hole is made of inflammable material.
Connection to a masonry flue
Make a hole for the flue connection in the wall. The hole
should be slightly bigger than the flue connecting pipe.
The pipe will later be sealed to the hole in the wall with,
for example, fireproof mineral wool. A suitable gap
around the pipe is ca. 1 cm.
First connect the flue connecting pipe to the
connecting piece on the rear of the furnace. Make sure
that the connecting pipe is tightly in place and tighten,
if needed, by hitting the pipe with a soft hammer. Also
ensure the sealing of the connection.
Move the fireplace or stove to the flue outlet and push
it towards the flue. Fill the gap around the pipe with
mineral wool and push the fireplace or stove into place.
Leave a space of approximately 50 mm between the
wall and the back of the furnace.
Make sure that the flue connection is tightly sealed
and add more fireproof mineral wool if necessary. Note!
If the flue connection is not tight, the draught
properties of the furnace will suffer and smoke may
seep into the room.
