5.9.2 CLOSED FIREPLACE UNITS
For fireplace units that are intended to dissipate heat via the outer
fireplace facing (masonry heater, hypocaustic system, systems with
closing convection air openings, etc.), and therefore dissipate heat
into the room via the facing, it is essential to observe the following
points:
•
The fireplace unit must be dimensioned and built according to
the relevant, professional tile fireplace and ventilation engineer
guidelines (new: TR OL 2006).
•
We recommend using sufficient storage material (e.g. Magnatherm)
to optimally use the heat and avoid the risk of overheating in tem-
perature spikes.
•
The size of the oven, i.e. the size of the heat dissipating surface,
should be determined depending on the heat output and heat requi-
rement.
•
The facing elements must be selected to meet the higher stan-
dards.
•
The builder should provide written instructions on the special type/
means of operation to the operator if possible. The quantity of wood
used has to correspond to the heat dissipation of the surface or the
storage capacity of the storage medium, for example (in general,
stoke no more than 2 – 3/day).
•
We recommend protecting installation surfaces made of combusti-
ble construction materials with active rear ventilation in addition to
the thermal insulation specified.
•
The insulation thicknesses listed on page 11 apply to warm air he-
ating systems only. For closed fireplace units, the insulation thick-
nesses have to be calculated as per TR OL.
•
For liftable combustion chamber doors, the temperature on the re-
verse or guiding rollers and the bearings must not exceed 270 °C.
And areas of the insert that have movable mechanical parts require
separate insulation.
•
When installing accessory parts, observe their installation specification,
especially the permissible operating or ambient temperatures and ac-
cessibility requirements, if any.
