7. Procedure
PNEG-1798 Tower and T-Series Dryers Vaporizer 19
7.3.1. Before running any piping, verify that the 2" burner pipe that has been previously installed through
the screen window and runs vertically along the outside dryer wall is plumb. This is very important
for the keeping the vaporizer piping that will run adjacent to the 2" burner supply line also plumb.
This makes for a professional looking installation when all three (3) pipes have been completed.
The 2" line is in the middle of the arrangement, the 3/4" liquid line is to the left of the 2" line and the
1-1/4" line is to the right of the 2" line.
(See Figure 7J.)

7.3.2. The vaporizer coil must be moved into a position where two (2) 1-1/4" SCH 80 90º elbows can be
screwed on to the coils inlet and outlet MNPT threaded ends. These elbows must be facing
downward when completed.
7.3.3. Move the coil into a position (if not already positioned) where the vaporizer inlet is to the left of the
2" burner line and the outlet is to the right of the 2" burner line. This as viewed looking downward
above the burner on the same side as the burner piping vertical run. The vertical vaporizer lines
begin from here.
