Maintenance Recommendations
Direct Fired Vaporizers are designed for trouble free and safe operation.
Because of the nature of their use, and the severe duty they receive, it is
important to provide scheduled maintenance. The maintenance schedule, type
and frequency, provided in this manual is the minimum maintenance required for
proper and safe operation of your vaporizer. Ambient conditions surrounding the
vaporizer installation and LPG quality may require a more frequent maintenance
schedule. A list of spare parts and repair kits for proper maintenance is located
in the Appendix section of this manual.
CAUTION
The equipment described in this manual is designed to operate with
LP gas, a flammable fuel under pressure. The nature of the
application involves inherent hazards that could result in injury.
ONLY a trained and fully qualified person should service this
equipment.
CAUTION
When servicing a component in the liquid or vapor line, BE SURE
that the LP-gas supply is shut off to that component before removal
or disassembly. Vaporizer must be completely purged before
performing service. Be sure that ALL sources of ignition are
extinguished within 25 feet (7.6 m) of the work area.
When flaring the contents of the vaporizer, be sure that the burners
are on to prevent freezing during the flaring operation.

– Initial Installation and Operation Inspections
Required 30-60 days after initial installation
Component Action Required
Inlet Strainer Inspect strainer and remove accumulated debris. NOTE: if debris accumulation is
heavy check every 3-6 months or more frequent as required.
Main Burner
Assembly Check orifices and air supply openings on the burner tips for debris or foreign objects.
If needed, clean any plugged or obstructed orifices before restarting the vaporizer.
NOTE: In some applications vaporizer may be installed in an environment where
excessive amounts of dust or debris are present. When vaporizer is located in this
type of an environment, it may be necessary to check the burner tips on a frequent
basis to ensure proper operation and capacity of the vaporizer.
Drip Leg Check the vaporizer drip leg, and any others present in the installation, for heavy ends
and oil build-up. If present, first ensure there are no sources of ignition within 25 feet
(7.6 m), and then drain heavy ends. NOTE: In areas where LPG quality is poor it may
be necessary for drip legs to be checked for heavy ends more frequently (monthly or
bi-monthly depending on quality of LPG). Once it is verified that no significant quantity
of heavy ends is accumulating during vaporizer operation, this maintenance can be
performed on an annual basis.
