Allcomponentsmustberatedfor350psigforLPuse.WARNINGHauck does not recommend installation of a linereducingregulator in the LP supply line. If theregulator diaphragm were to rupture, total system pressure would be applied to the burner andcould result in damagetoequipment,includingthebaghouseand result in serious injury topersonnel.2.Close the ball valve upstream of the LP solenoid valve (see fig. 13).3.Open the shutoff valve on the inlet side of the pump and turn on the LP pump.4.Start LP flowing to the burner LP manifold.5.Check all LP lines and connections for leaks, following accepted standards and practices.6.Open the ball valve upstream of the LP solenoid valve and check the burner LP manifold for leaks (see fig. 12).Fig. 13- Schematic to aid in adjusting the constant pressure regulator system.(page 3-518)
