1. Ensure all tank valves are open with no restrictions of flow back to the
storage tank. A check valve restricting flow back to the storage tank
must never be used in a vaporizer installation.
2. Close outlet shut-off valve at the exit of the vaporizer.
3. Start burner per Direct Fired Vaporizer startup procedure and turn the
thermostat temperature control dial to the highest setpoint (7).
4. After the burner cycles off, turn thermostat temperature control dial to OFF
position, shut off reigniter (if installed) and check that the pilot flame is
extinguished.
5. After the pilot flame is extinguished, close shut off valve prior to the
vaporizer in the liquid line.
6. Now open vaporizer outlet valve and flare or allow attached equipment to
consume the remaining gas in the line.
7. After verifying the pressure in the lines is zero and no sources of ignition
are present in the area, the vaporizer can now be disconnected.
AUTOMATIC RE- IGNITION OPERATION
Lighting or re-lighting of the pilot flame is accomplished by a spark across a gap
of approximately 1/8’’ (3 mm) from the electrode tip to the grounded surface of
the pilot. When the flame is established, the pilot flame conducts a current to the
grounded pilot burner and a solid-state switch in the unit turns off the spark. If
the pilot flame is extinguished, current to ground is interrupted and the solid-state
switch turns on the spark, which sparks at a nominal timing of 100 times per
minute, re-lighting the pilot flame well before the thermocouple cools enough to
drop out the thermostat safety system.
