Smeg PTS723-3 User Manual

 

 

 

 

 

The hob is tested with G20 (2H) natural gas at the pressure of 20 mbar.  
If it is to be used with other types of gas, the burner nozzles have to be changed and 
the primary air flow adjusted. 
To replace the nozzles and adjust the burners, the hob plate has to be removed as 
described below.

 

 

Remove all the burner components in the numerical order shown below: 
•  Remove the pan stands (Fig.1) by lifting them at the back (1) and extracting them 

(2); 

•  remove all the knobs (3, Fig.2) by pulling them outward; 
•  lift all the burner components off the hob (4-5, Fig. 2); 
•  use the spanner 6 (Fig. 3) to open the bayonet fastenings of the burner fixing rings, 

applying leverage on the guides 7; 

•  after removing all the components described above, lift the front of the hob skin (8, 

Fig. 4).  

•  the burners and gas taps can only be accessed by pushing the rear of the hob 

gently upwards with the aid of a tool (9-10, Fig. 5). 

This is necessary to release the internal snap fixing devices. The hob skin can now be 
removed. Some models may have 2 additional pins at the side (Fig. 5), which must be 
removed in the same way, using a tool to apply leverage to the hob.
