FIGURE 24: End Vent Vacuum
Note: System vacuum should be set by measuring vacuum pressure at end burner
furthest away from vacuum pump. All other end burners on the other branches should
have the same vacuum pressure reading. The vacuum pressure on end burners
closer to the vacuum pump are set by adjusting the damper on the damper coupling
for each branch.
