Hauck strongly recommends that a Flo-Control valve and a back-pressure regulator (available
from Hauck) be installed in all LP systems and piped as shown in fig. 13 (see also, GX4059). All
components must be rated for 350 psig for LP use.
Hauck does not recommend installation of a line reducing regulator in the LP supply line. If the
regulator diaphragm were to rupture, total system pressure would be applied to the burner and
could result in damage to equipment, including the baghouse and result in serious injury to
Close the ball valve upstream of the LP solenoid valve (see fig. 13).
Open the shutoff valve on the inlet side of the pump and turn on the LP pump.
Start LP flowing to the burner LP manifold.
Check all LP lines and connections for leaks, following accepted standards and practices.
Open the ball valve upstream of the LP solenoid valve and check the burner LP manifold for leaks (see fig. 12).
