2. BASIC REQUIREMENTS FOR
SETTING UP AN OPEN FIREPLACE
Before installing the fireplace insert, you have to make sure that
the air controls function perfectly and make them function if they
do not. Consult the local building code inspector responsible as to
whether the chimney and combustion air intake are suitable before
beginning installation. Note and apply DIN 18160 and DIN 18896.
Apply the relevant standards in DIN EN 13229 as well. Every open
fireplace requires its own chimney. Multiple use is only permitted
when the unit is to be operated closed (Type A1).
Perform the chimney calculation as per DIN 4705 T1, T2 or EN
13384-1 with the value sets specified in these instructions. The
convection sheath in stock is not required for tiled fireplaces. Set up
the combustion system according to the professional tile fireplace
and ventilation engineer guidelines („TROL-Richtlinien für den Bau
von Kachelöfen," available from Central Association for Sanitation,
Heating and Air-conditioning (ZVSHK), Rathausallee 5, 53729 St.
Augustin, Germany).
3. LOCATIONS AND COMBUSTION AIR SUPPLY
3.1. BASIC REQUIREMENTS OF LOCATIONS FOR OPEN
FIREPLACES AND PROHIBITED LOCATIONS
Open fireplaces may only be installed in rooms and places in which
the location, construction situation and type of utilization do not
lead to hazards. In particular, when the type is dependant on indoor
air, sufficient combustion air must flow into the locations. The floor
space of the location has to be designed for the proper operation
of open fireplaces and has to be large enough.
3.2. THE OPERATION OF OPEN FIREPLACES IS
NOT HAZARDOUS IF...
... the units have safety devices that automatically and reliably
prevent a partial vacuum from forming in the location, or
... the total combustion air volume flow rates and the exhaust system
air volume flow rates required for open fireplaces do not cause a
partial vacuum greater than 0.04 mbar in the open fireplace location
and the rooms of the ambient air network.
3.3. OPEN FIREPLACES MAY NOT BE INSTALLED:
... in stairways, unless they are in residential buildings with
two apartments or less
... in hallways with general access
... in garages
... in room in which highly combustible or potentially explosive
substances or mixtures are processed, stored or manufactured in
quantities that would be hazardous in the event of ignition or
explosion.
Open fireplaces may not be set up in rooms or apartments in which
the ventilation system or forced-air heating system is ventilated
with fans unless the open fireplace has been inspected and deter-
mined to function safely.
