SAFETY NOTES 

 

Before  commissioning,  please  read  the  documentation  carefully  and  pay  attention  to  the  safety 
instructions given in particular. Please consult this manual if anything is unclear. 

 

Make  sure  that  you  understand  the  instructions  contained  in  this  manual  and  that  you  are  sufficiently 
informed regarding the way in which the biomass boiler system works. Should you have any queries at 
any time, please do not hesitate to contact HERZ. 

 

For safety reasons, the owner of the system must not make any changes to the construction or the state 
of the system without consulting the manufacturer or his authorised representative. 

 

Make  sure  that  there  is  a  sufficient  supply  of  fresh  air  to  the  boiler  room  (please  heed  the  relevant 
national regulations) 

 

All  connections  are  to be  checked  before  the  commissioning  of  the  system  in  order  to make sure  that 
they are leak-tight. 

 

A  portable  fire-extinguisher  of  the  prescribed  size  is  to  be  kept  by  the  boiler  room.  (Please  heed  the 
relevant national regulations). 

 

When  opening  the  door  to  the  combustion  chamber,  make  sure  that  no  flue  gas  or  sparks  escape. 
Never leave the combustion chamber door open unattended as toxic gases may escape. 

 

Never heat the boiler using liquid fuels such as petrol or similar.  

 

Carry  out maintenance  regularly  (in  accordance  with  the  maintenance  schedule)  or  use  our  Customer 
Service department. (The minimum maintenance intervals specified in the TGPF are to be observed).  

 

When  carrying  out  maintenance  on  the  system  or  opening  the  control  unit,  the  power  supply  is  to  be 
disconnected and the generally valid safety regulations are to be heeded. 

 

In the boiler room, no fuels may be stored outside the system. It is also not permitted for objects which 
are not required for the  purpose of operating  or carrying  out maintenance on the system to be kept in 
the boiler room. 

 

When filling the fuel bunker using a pump truck, the boiler must always be switched off (this is stamped 
on the cover of the filling connection). If this instruction  is not heeded, flammable and toxic gases may 
get into the storage room! 

 

The fuel bunker is to be protected against unauthorised access.  

 

Always disconnect the power supply if you need to enter the fuel bunker. 

 

Always use low-voltage lamps in the storage room (these must be approved for this type of use by the 
relevant manufacturer). 

 

The system is only to be operated using the types of fuel prescribed. 

 

Vor weitem Transport der Asche muss diese für eine Auskühldauer von mind. 96 Std. zwischen gelagert 
werden. 

 

Should you have any queries, please call us on +43 3357 / 42840-840.  

 

Initial commissioning must be carried out by the HERZ Customer Service department or an authorised 
specialist (otherwise any warranty claim will not be applicable). 

 

Ventilate the pellet storage area for ~ 60 minutes before going in. 

 

The  boiler  meets  the  requirements  of  the  Association  of  Swiss  Canton  Fire  Insurance  Companies  or 
national  fire  safety  regulations.  The  customer  himself  shall  be  responsible  without  exception  for 
ensuring that these regulations are complied with on site!
