Flame Calibration 

– Sit Nova 826 

 
The  following  section  explains  the  calibration  procedure  for  the  Sit  Nova  826 
Combination  Gas  valve.  The  valve  allows  for  use  with  both  Propane  and  Natural  gas, 
however the jet in the burner will need to be changed and the data plate updated when 
converting  gas  types.  Conversion  kits  are  available  to  purchase  from  Beech  Ovens 
Head Office (

[email protected]

) or your local Beech Ovens representative. 

 

Note:

 

Never  attempt  to  convert  gas  types without  first  changing the  burner  jet 

and data plate in the Gas control cabinet.
