AIR TUBES INSTALLATION (HT-2000): 
 
The secondary air tubes are painted different colours . The back tube is yellow, the middle 
on is red and the front is unpainted. Before installing, make sure the locating holes in the 
tubes (holes near one end of the tube) are on the left side. Insert one tube in the right side 
air channel and slide it to the right as much as possible. Bring the left end of the tube aligned 
with the ring welded to the left air channel. Move the tube to the left until the locating holes 
are aligned with those in the ring. Insert a cutter pin to hold in place. The air injection holes 
should be facing down in the front and middle tubes.
