N. LP GAS FUEL PIPING SYSTEM
Hauck requires the use of oil manifolds which meet NFPA guidelines. NFPA requires two shutoff
valves piped in series in the burners main oil line. A low pressure switch must be interlocked with
the burners shutoff valves. Haucks LP manifolds have been designed to meet NFPA
LP is highly flammable and heavier than air. It will accumulate near the ground in the area of a
leak and it dissipates relatively slowly.
Before attaching fuel lines, purge the lines with compressed air.
Connect the main LP line at the appropriate connection on the burner skid.
All piping must be schedule 80 or heavier and all valving must be suitable for 350 psig service. The capacity of the
fuel system must be 1-1/2 times the rated capacity of the blower.
If Hauck has supplied the LP pump set for this application, consult the pump installation instructions for
information on this unit.
