Injection nozzle
• GTU C 123 – GTU C 124 - PU 153 Condens – PU 154 Condens
In order to allow for any problems on site, Delavan 80°A injection
nozzles can be replaced by Danfoss 80°S injection nozzles
• PU 155 Condens (F) – GTU C 125 (FF) boilers (see table below)
We recommend at inspection or when the system is being handed
to replace the nozzle by a Fluidics 60°SF nozzle.
