Ornamental beams: Ornamental beams are allowed in front of the fireplace coating at a distance of 1 cm at least if the ornamental beam is
not a part of the building and the intermediate space is such that it does not accumulate heat and the ornamental beam is not situated within
the area of the insert heat radiation.
Fire protection in a heat radiation area
A minimum distance of 80 cm forwards and sideways must be retained in front of the firebox hole (pict.5, position 1). If the
protection against heat radiation is from both sides, a distance of 40 cm is enough (pic. 5, position 2).
Fire protection above a heat radiation area
A minimum distance of 5 cm from the outer space of the insert coating to non-
combustible building panels must be retained. Air space must be clear so as not to
accumulate heat (pict. 5, position 3). Building panels covering only small coated
areas of the fireplace insert, e.g. floors, wall coating and thermal insulation layers
may abut onto the coating (pict. 5, position 4). Wider combustible building
panels, e.g. ornamental beams, may be at a distance of 1 cm from the insert
coating (see Ornamental beams).
External combustion air income
Hot AIR fireplace inserts are adjusted for direct connection for external
combustion air inflow. Bellmouth of diameter of 120 – 150 mm for external
combustion air connection is ending on the back side (or bottom side) of the
fireplace insert. Inflow for outdoor air connection for combustion in a fireplace
insert must have as few bends as possible. For air inflow within the distance of
1.5 m with one bend (max. 90°) it is possible to use a pipe of diameter 100 mm.
For air inflow within the distance of 3 m with one or two bends (total disjunction
of angles 135°) it is possible to use a pipe of diameter 125 mm. When there is
longer distance and more bends, it is necessary to take into account air resistance
caused by friction of tube walls.
It is possible to supply hot air fireplace inserts with automatic electronic regulation of the combustion process. Automatic regulation consists of
control unit, control damper and temperature sensor. Control dumper must be situated in supply pipes, as close as possible to fireplace insert and
connect hermetically onto bellmouth of the air inflow. After building of the fireplace, the dumper must be accessible for service. When
automatic regulation is in use, it is convenient to set up the hand-operated element in the 2/3 open position (providing right proportion of the air
for nominal output of the insert). Also, fireplace insert can be fitted with door contact for easy service (position of the door contact is described
below in paragraph “door adjusting and unhanging). More detailed description of connection and installing you will find in installing document
of Automatic regulation.
When automatic regulation is in use, manually operated element must not be closed!
Firebox running
Hot air fireplace inserts are suitable either for closed or for open spaces.
Fireplaces with open hearth must be supervised all the time to prevent dangerous sparks and falling out wood pieces burning.
Fuel
Fireplace inserts can be operated only with the following fuel:
dry wooden logs
ONLY DRY WOOD LIBERATES LITTLE HARMFUL POLLUTANTS DURING BURNING!!!
A fireplace insert is not suitable for waste burning!!!
Combustion air input
It is necessary to supply a sufficient amount of external air into the room when using the fire. Both open and closed fireplaces require an
adequate amount of fresh air. The steps for combustion air input cannot be changed and combustion air inputs must be open during the working
operation of the firebox.
Convection air
To prevent heat accumulation, the incoming and outgoing grates of convection air must be open when using the fire. To prevent heat
accumulation in heat distributing system, length of horizontal distribution piping must not be longer than 2,5m. The piping must always lead up.
Exit can´t lead vertically down.
We recommend ordering a professional firm to install hot air piping!
Fire protection above a heat radiation area
A minimum distance of 5 cm from the outer space of the insert coating to non-combustible building panels must be retained
