Direct Fired Vaporizer start up procedure
1. Before starting the vaporizer, close the outlet valve in the vapor service
line.
2. Fill the vaporizer with LP gas liquid by slowly opening the liquid supply
line valve between the storage tank and the vaporizer. If this valve is
opened too quickly, the excess flow valve in the tank may close. If this
occurs, close the liquid supply line valve and allow the excess flow valve
to equalize and re-open.
3. If the vaporizer is installed with a separate burner supply line not
connected to the vaporizer (
see page 2-7
), open the valve supplying gas
to the burner supply regulator.
4. Turn the temperature control dial on the thermostatic gas control valve
counterclockwise to the "RUN" position. “RUN” position indicates that
the pilot and main burner can start operating.

5. Turn the reigniter switch to “ON” and press the pilot button down (see
Figure 6). Continue to hold the pilot button for 30 to 60 seconds and
release. Pilot should remain lit.
NOTE:
If the ambient temperature is below 10°F (-12°C) when the pilot
button is released it is likely that the main burner will immediately cycle on.
As soon as the LP gas inside the heat exchanger heats up above this
temperature the main burner will cycle off. This is normal operation for the
thermostatic gas valve.
