SETUP AND INSTALLATION
/j\ Connecting to an extraction system
Comply with the applicable national environmental regulations for the extraction of
exhaust gases released during the heat treatment. Suitable measures must be
implemented to ensure that such gases are safely led outside (FRG: BlmSchG). Such
measures may involve thermal or catalytic treatment of flue gases.
Refer to the TECHNICAL DATA section for the volume flow and temperature of the exhaust
gases.

Draft breaker
Implementation instructions:
• A draft breaker must be used to connect the unit to an extraction system.
• All flue ducts must be made of fireproof materials.
• Apertures must be provided to enable the removal of residue and condensate. The flue
ducts must be thermally insulated (recommendation: half-shell sleeves made of laminated
mineral Tiber).
• The exhaust air / gases from the unit must never come into contact with combustion ex-
haust gases.
• Use the draft breaker to adjust the air flow volume in such a way that exhaust gases can be
extracted reliably without producing any eddying at the unit's exhaust-gas connector.
• Technical measures should be implemented to monitor the flow of air and flue gases and to
prevent operation of the heating unit if the ventilation system Is switched off / defective
(electrical interlock).
