Gas Conversion for Top Convertible Pilot (Series 019065X) – PART B 

 
 

Instructions for converting SIT 190 series pilot burner injection from NG to LPG and from NG to LPG only. This 
information should be considered as supplemental to the Appliance Manufacturer’s Instructions. 

 WARNING: The installation of this conversion kit must only be undertaken by a qualified and certified gas 

appliance installer. 

 

1.  Shut off the gas supply to the appliance. 

2.  Allow the pilot burner to cool to room temperature. 

WARNING: Touching a hot pilot burner can 
result in injury.

 

3.  The pilot hood is held in place by spring pressure. 

Remove the hood by pulling it directly up from the 
pilot bracket (a). 

4.  Insert a 5/32” or 4mm Allen wrench into the 

hexagonal key-way of the injector (b), and rotate it 

4

 counter-clockwise until it is free of the injector 

journal (c). 

5.  Verify that the new injector is proper for the 

application. The injector size is stamped on the 
side of the injector near the top. LPG injectors have 
a groove machined around their circumference 
near the top, while NG injectors do not have a 
groove (e). Refer to the Appliance Manufacturers 
instruction sheet for the proper injector size. 

6.  Insert the Allen wrench into the end of the injector. 

Then, insert into injector journal, and rotate the 
injector clockwise until a torque of 9 in-lbs is 
achieved. 

7.  Replace the pilot hood by aligning the tab on the 

base of the hood with the slot in the side of the pilot 
journal, and push the hood down, directly onto the 
pilot bracket (d). The hood must sit squarely on the 
bracket for proper operation. Check to insure that 
the hood is properly seated onto the pilot bracket.

 WARNING: This conversion kit must only be applied as part of a conversion kit supplied by the appliance 

Manufacturer for the specific appliance, and type of gas being converted. 

INSTALLER NOTICE: These instructions must be left with appliance.
